Today’s Alpha Launch marks the first live deployment of Energy Web’s Verified Compute Cloud (VCC) on Energy Web X, leveraging the blockchain platform’s advanced capabilities, including the newly introduced EWX liquid staking. This integral solution enables EWT holders, participating as stakers and/or VCC compute node operators, to be compensated for serving sustainability markets via protocol-level VCC solution service fees. The first commercial VCC pilot on EWX facilitates a decentralised, multiparty validation of public Sustainable Aviation Fuel Certificate (SAFc) data on the SAFc Registry which can be tracked in the explorer.

Liquid staking is one of the key enablers of this digital service, allowing EWT holders to stake their tokens without removing them from circulation. They deposit EWT into a pooled nominator and receive stEWT, a liquid representation of their stake. This stEWT can simultaneously contribute to EWX network security and be re-staked to back the accountability requirements of a VCC solution. Importantly, pooling removes the barrier for smaller actors who do not have the capacity or do not wish to manage infrastructure to engage in on-chain network activity. Moreover, any received rewards are automatically restaked, increasing the stEWT:EWT exchange rate over time without minting new tokens (exchange-rate changes reflect protocol mechanics and service-fee distribution, not guaranteed growth or financial return). This simplifies the staking process for users, removes the need to manage delegations and restake rewards while compounding utility, safeguarding network security and avoiding excessive concentration of stake. Slashing is an important part of this process as it prevents malperformance.

Verified Compute Cloud EWX Pilot Application in Partnership with SAFc Registry

Verified Compute Cloud is Energy Web’s innovative off‑chain business logic computation service with on-chain finality, supporting verification, automation and auditability for sustainable, mission-critical enterprise solutions.The VCC Alpha Launch introduces the first live Verified Compute Cloud pilot on the EWX network, conducted in partnership with the SAFc Registry. The SAFc Registry, founded by three clean tech organisations, the Rocky Mountain Institute, the Environmental Defense Fund and SABA, has been operated by Energy Web since its launch at the December 2023 COP28 climate conference in Dubai. With the VCC model innovation introduced in December 2025, the SAFc Registry principle workflows will be continuously audited, embedding data input and process outcome authenticity. EWX network participants engaged in this VCC solution delivery will validate public SAFc Registry data for each retired (officially issued) certificate.

In this process, independent distributed nodes (VCC operators) verify emissions-reduction calculations, check whether certificates were previously claimed, and corroborate whether each retirement meets SAFc classification rules on beneficiary type, claim year, and production and blending dates. Energy Web’s VCC service solidifies confidence in the integrity and accuracy of each SAFc retirement, delivering a higher-quality and more reliable level of oversight than is possible with today’s largely manual, scope and time-restrictive audit processes. For EWX network stakers, this pilot represents the first opportunity to deploy stEWT to support a live Verified Compute Cloud solution. By staking into the SAFc Verified Compute Cloud solution group, participating EWT holders contribute directly to securing an important sustainability process validation. SAFc VCC Solution payment (service fees) is routed on-chain to compensate performant EWX network participants based on their operational and staking contributions, with payments executed in stablecoin (USDC) pursuant to a solution compensation contract over the three-month technical alpha launch period. VCC service fees are expected to increase gradually throughout the period, as more certificates are purchased on the SAFc platform, increasing the total available compensation pool. Service fees will also be variable, since the number of certificates purchased via SAFc Registry varies from month-to-month. No specific level of compensation is guaranteed, with relevant parameters adjusting based on participation levels, network performance and any future upgrades or modifications related to network operations. Any received USDC-denominated service fees can be held by users in their wallet on the EWX network, or transferred to Polkadot Asset Hub via wallet providers (such as SubWallet), or via extrinsic calls through Polkadot.JS for any further action or exchange.

How EWT Holders Can Prepare and Participate

Through the ecosystem of applications on EWX, users will be able to participate in the SAFc Verified Compute Cloud solution by acquiring (or moving their tokens to EWX), liquid staking and then committing their stEWT to the relevant Verified Compute Cloud Solution Group (VCG). The first step is to ensure a sufficient EWT token holding on EWX, and based on current mechanics a minimum of 3,500 stEWT is required to subscribe to the Alpha Launch VCC SAFc solution group. If EWT holders store tokens on the legacy Energy Web Chain, or have already bridged tokens to Ethereum, they can use the Energy Web Bridge interface and this guide to move these to EWX. Next, participants should liquid stake their EWT tokens on EWX, through the EWX Staking interface using this guide, receiving stEWT in return. Finally, the EWX Marketplace interface can be used to select the SAFc solution group, complete the KYC process and contribute stEWT to complete the subscription process. Guides for completing the KYC process and subscribing to solution groups can be found here.

During the initial phase of the SAFc VCC pilot, staking contributions will be open to any KYC-ed user, while the VCC computation service operation shall be limited to a vetted set of operators. At the discretion of the SAFc registry governance as a VCC client, VCC operation may be expanded to include a broader segment of the community as the pilot progresses. This phased approach allows the community to begin participating immediately through staking, while ensuring that node operations scale efficiently as Verified Compute expands.

VCC Service Slashing Mechanics

The VCC solution technical alpha launch applies an initial, conservative slashing configuration for Verified Compute Cloud operators, designed to enforce baseline performance and protocol compliance while allowing greater operational tolerance during this first production validation phase. The operational objective of this phase is to collect real-world performance data and validate end-to-end workflows under live conditions. Accordingly, slashing thresholds are intentionally set at higher tolerance levels than those expected under standard operating conditions. As an additional protection measure, any slashed funds are temporarily routed to a multisignature-controlled holding address for review and may be returned where slashing is determined to be unwarranted under the applicable VCC protocol.

The causes for slashing fall into two categories: Operational Penalty and performance penalties. Operational Penalty are triggered based on an outcome of a disputed or failed voting round (the cycle in which operators submit their verification results on-chain). The penalty renders orchestrated attacks and malicious behaviour economically unviable, while protecting the reliability of outcomes of applications leveraging Verified Compute Cloud. Operational Penalty would only occur under extreme and rare circumstances, but must remain sufficiently strong to achieve the aforementioned objectives. Performance penalties monitor each VCC operator’s individual performance in a voting round, penalising those that fall far below the agreement performance thresholds. These penalties ensure a minimum quality of service from each operator.

Energy Web X On-Chain Service Scaling

The SAFc VCC Solution Alpha Launch brings together the core components of the 2025 Energy Web platform upgrade into a single operational workflow for the first time.

• Verified Compute enables verification, automation and auditability for sustainable, mission-critical enterprise solutions;
• Liquid Staking (stEWT) expands participation and unlocks new on-chain utility;
• Energy Web Bridge provides multichain mobility and broader ecosystem reach;
• The SAFc Pilot demonstrates these capabilities in a real, commercial application context and delivers immediate value to management and users of the SAFc Registry.

Together, these components form the foundation of a decentralised digital infrastructure designed for high-integrity climate and energy applications. They enable continuous validation, transparent audit trails and automated rule compliance, all of which are essential for markets such as renewable energy tracking, sustainable fuel certification, supply chain emissions accounting and grid operations. This launch marks the beginning of a new phase for Energy Web X, where staking, compute and real-world decarbonisation workflows operate together to deliver trust, automation and transparency at scale.

Why This Matters

A growing number of applications in the energy sector and beyond are leveraging decentralized Worker Node networks on Energy Web X. For example, Green Proofs for Bitcoin (GP4BTC) uses EWX to verify green Bitcoin mining, and the recently launched Carbon-Aware Nomination system orchestrates compute workloads to maximize the use of clean energy. As these and other DePIN (Decentralized Physical Infrastructure Networks) use-cases expand, it becomes ever more critical to enforce accurate and verifiable computation in a secure, scalable manner.

This consensus upgrade directly addresses that need. It introduces several improvements to how EWX validators reach agreement on Worker Node outputs and distribute rewards: changes that align incentives with performance and ensure the integrity of off-chain execution. This upgrade empowers enterprises to pair their off-chain computational systems with highly configurable on-chain reward mechanisms, creating strong business and financial incentives for both enterprises and community members operating Worker Nodes to actively contribute to these decentralised systems.

Setting The Bar on Performance

Only the most consistent, high-performing worker nodes will now be rewarded for their contributions. The upgrade introduces an SLA performance threshold, a minimum standard for correct vote submissions that a node must meet to qualify for any rewards. In other words, a worker’s voting accuracy over each reward period has to exceed a predefined percentage (set on a per-Solution Group basis) for that node to earn a share of the rewards. A “correct” vote means the worker’s submitted result from their off-chain execution aligns with the majority consensus for a given round (as determined by EWX validators). If a node’s correct vote rate falls below the threshold, it won’t receive rewards for that period, no matter how many votes it cast.

This change pushes every Worker Node operator to perform above a clearly defined bar. Energy Web X validators now track each worker’s voting performance across rounds (via on-chain metadata) and calculate the percentage of that worker’s votes that matched the accepted consensus. Only those exceeding the SLA threshold are deemed eligible. Among those that qualify, rewards are weighted by accuracy and stake, meaning those who contribute more correct results and have more stake on the table earn proportionally more. See the reward formula below:

worker_reward = (worker_correct_votes × user_stake) / total_weighted_correct_votes × voting_reward_per_block × active_blocks

Where:

• worker_reward: the amount of EWT distributed to the worker node operator as their active reward for participation in eligible voting rounds within the concluded reward period.
• worker_correct_votes: The number of correct (consensus aligned) votes submitted by the worker node in the eligible voting rounds within the concluded reward period.
• user_stake: The amount of tokens locked by the operator upon registration.
• total_weighted_correct_votes: Sum of correct votes weighted by stake across all worker nodes ( Σ(correct_votes_i * stake_i) ).
• voting_rewards_per_block: Amount of tokens allocated to voting rewards per block (configured by the solution registrar).
• active_blocks: Number of blocks spanning the reward period.

Worked example:

A Solution Group contains 150 operators. At the end of a reward period, 100 operators submitted sufficient votes to exceed the SLA threshold and are eligible for rewards.

From the eligible 100 operators, the average correct votes during the reward period is 100 and the average user stake is 1000.

Therefore: total_weighted_correct_votes = 100 * 100 * 1000 = 10,000,000

Worker Node A had 110 correct votes with a stake of 1000. There are 7200 active blocks in a voting round, and the voting rewards per block are set to 1 token.

Therefore: worker_node_A_reward = (110 * 1000) / 10000000 * 1 * 7200 = 79 tokens

Consensus Validated Via Quorum & Majority Threshold

The consensus mechanism employs a two-tier validation process to guarantee both sufficient participation and accuracy of submissions before finalising the result on-chain. Energy Web X requires two conditions for a voting round to produce a valid result:

• Quorum: A minimum percentage of eligible worker nodes must participate by submitting their votes.
• Majority Threshold: Within the specified quorum of participants, a majority of workers, over the defined threshold, must agree (i.e. submit matching results) for the result to be accepted as the round’s consensus.

If either condition isn’t met the round is marked Unresolved. These thresholds optimise for security and trust without sacrificing scalability. Quorum ensures that a sufficiently broad sample of the network contributes to each consensus decision, while the majority threshold ensures accuracy and trust in the result. Only when both conditions are satisfied will the Energy Web X validator set record the final result on-chain.

Improving Withdrawal Delay

The upgrade also refines how and when worker node operators can withdraw their stake from the network. The withdrawal delay is the period a user must wait between submitting an unsubscription request and receiving their tokens. This means every action (vote) has a consequence: correct votes will always be rewarded while protecting against malicious actors who may otherwise submit false votes and then withdraw to evade penalties.

With the upgrade, withdrawal delays are measured in reward periods instead of blocks. In practice, after an operator initializes a withdrawal, they must wait a defined (by the registrar) number of additional reward periods before withdrawing their collateral. During this delay period, the node can still participate in voting rounds and continue to earn rewards, except for the final reward period in which the stake is released and voting eligibility ends. This ensures all pending rounds are properly settled and any rewards or penalties processed before a node can exit the network.

For example, a solution group has a withdrawal delay of 2 reward periods. A subscribed worker node operator votes in Reward Period 1 then submits an unsubscribe request in Reward Period 2. The operator would need to wait for Reward Period 3 and 4 to conclude, before receiving their funds back during a block (specific timing depends on system load) in Reward Period 5. The operator can participate (vote) in Reward Period 3 and 4 but not in 5.

The Outcome: Accurate, Scalable and Secure Off-Chain Compute

Together, these enhancements bring Energy Web X’s consensus mechanism in line with the vision of incentivizing top-performing worker nodes to deliver accurate, verifiable outputs from off-chain computation.

What does this mean for Energy Web ecosystem participants? Solution owners and their users can have complete trust in the outputs of decentralised compute. Energy Web X’s blockchain will securely handle the heavy lifting of coordinating nodes, validating results, and distributing rewards, all in the background. This allows developers and enterprises to focus on what they do best: building high-value applications, confident that a robust, trusted decentralized compute layer is reliably powering their workloads behind the scenes.

A New Era for Sustainable Computing

Demand for computing power is exploding as AI models, cloud services, and decentralized applications consume ever-greater amounts of energy. But not all energy is created equal. In some regions, a data center might be drawing power from a coal-heavy grid, while elsewhere excess wind or solar power goes unused. For the past decade, tech giants addressed this by buying renewable energy or improving efficiency. But what if we could take a more dynamic approach — shifting computational workloads across location and time to maximize use of clean energy?

Enter Carbon-Aware Nomination, a groundbreaking mechanism from Energy Web that does exactly that. It ensures computational tasks run where and when they have the lowest carbon intensity. This isn’t a standard cloud feature or a typical blockchain project, but a fusion of both: it connects decentralized computing networks with real-time carbon intensity data from WattTime and the Green Software Foundation’s Carbon-Aware SDK. And the best part — it’s going open-source, inviting the entire industry to build a greener digital future together.

The Carbon Cost of Computing: Why It Matters

Computing today has a massive carbon cost. Data centers account for around 1–2% of global electricity use (on par with the airline industry), and that share is rising fast. Some forecasts warn that with the AI boom, data center energy demand could hit double-digit percentages of global consumption by 2030. In short, if we don’t make computing more sustainable, it will hinder global climate goals. Today’s solutions to decarbonize workloads rarely have real-time “carbon awareness.” This means a lot of flexible computing — like batch processing or AI training jobs — might be running at the worst possible times for the planet. Carbon-Aware Nomination changes that paradigm by intelligently routing workloads to times and places where electricity is greenest.

Why Carbon-Aware Nomination Is a Game-Changer

Carbon-aware computing isn’t an entirely new idea, but no one has implemented it the way we have. Existing approaches have serious limitations:

• Blind Spots in Conventional Cloud Sustainability: Major cloud platforms have introduced sustainability dashboards and efficiency tools to help customers estimate carbon footprints. However, these proprietary solutions require you to trust their reporting. There’s no independent way to verify if a given workload actually ran on low-carbon energy. In other words, you might see carbon-saving claims, but you can’t prove them. While Carbon-Aware Nomination is built for decentralized compute networks, its methodology could be adapted for cloud orchestration. However, the current implementation is blockchain-native, ensuring verifiable, tamper-proof sustainability claims.
• Decentralized Compute Lacks Climate Intelligence: Emerging networks like iExec, Golem, and Akash distribute workloads across many nodes, leveraging blockchain for compute marketplaces. Yet, they schedule jobs without considering the carbon intensity of those nodes. A task might just as easily run on a coal-powered node as on a solar-powered one. Until now, no decentralized computing platform has integrated real-time carbon optimization into its scheduling logic.

This is where Carbon-Aware Nomination stands apart. It combines decentralized computing with live carbon-intensity data for the first time. By doing so, it delivers several unique benefits that neither traditional clouds nor existing blockchain compute projects offer:

1. Decentralized & Trustless Architecture: Built on the Energy Web X blockchain, every decision and claim is transparent. There’s no single company controlling the process, and sustainability claims are tamper-proof and verifiable by anyone. This brings a new level of trust to green computing — auditors or stakeholders can confirm, via the public ledger, that a workload ran at a time of low grid emissions.
2. Real-Time Carbon Intelligence: The system taps into WattTime’s API and the GSF Carbon-Aware SDK to get live and forecasted grid emissions data. Workloads are continuously matched to the cleanest energy times in real time. If wind picks up in Region A or solar output surges in Region B, the scheduler knows and can route tasks accordingly. We’re not offsetting carbon with credits or averaging it annually; we’re actively avoiding emissions as they happen.
3. Hybrid Public/Enterprise Nodes: Flexibility is built in. Organizations can nominate workloads to run on public decentralized nodes or their own infrastructure — whichever meets the carbon criteria. For example, an enterprise could use its private servers when they’re running on green power, or tap into a public pool of nodes in another region when local power is dirty. Carbon-Aware Nomination isn’t “all or nothing” — it’s a smart overlay that finds the greenest option across a mix of resources.
4. Verifiable ESG Reporting: Every workload handled through this system generates a digital proof of its execution with associated carbon data. Think of it like an eco-receipt. This proof can feed directly into ESG reports or sustainability audits, backed by blockchain records. Instead of saying “we think our computations were low-carbon,” organizations can cryptographically demonstrate it. This level of accountability is increasingly crucial as investors and regulators demand hard evidence of climate action.
5. Open-Source Collaboration: Unlike proprietary cloud solutions, Carbon-Aware Nomination is being released as open-source software. This invites an entire community — from researchers to startups — to use it, audit it, and improve it. By sharing the code, Energy Web ensures transparency of the algorithm and accelerates innovation. Anyone will be able to plug into the system or even contribute new features (for example, supporting new types of workloads or integrating additional data sources). We believe an open approach is the fastest way to standardize carbon-aware computing across the world.

How It Works (In Simple Terms):

1. Checks Carbon Data: A group of computers (nominators) analyze real-time electricity grid data to find where energy is greenest.
2. Finds the Best Spot: The nominators select and agree on the cleanest available computing resources to execute the workload and qualify for rewards.
3. Runs & Verifies: The selected computers can accept and execute the workload, and the blockchain records proof of completion, ensuring eligibility for rewards.

How It Works (In detail): The Carbon-Aware Nomination Pool

So, how does the system actually orchestrate a “greener” workload? Rather than a central scheduler deciding where tasks run, Carbon-Aware Nomination uses a decentralized pool of worker nodes and nominators that collectively determine the optimal execution plan. Here’s a high-level look at the process:

• Live Carbon Data Feeds: Using the Carbon Aware SDK, the system continuously pulls real-time and forecasted carbon intensity data from WattTime’s service. This data covers different regions and grids, updating as conditions change (like when a big solar farm comes online in the afternoon or when a coal plant ramps up at night).
• Normalized Comparison: Because “100 gCO₂/kWh” means different things on different grids, the scheduler normalizes carbon intensity across regions. This prevents it from always favoring the same region and ensures a fair comparison. In essence, the algorithm knows what “clean” means for each location and time — a form of smart context.
• Energy Web X Worker Registry: All participating compute nodes (whether run by individuals, companies, or data centers) register on the Energy Web X blockchain registry. They publish metadata about their location, hardware, and efficiency. This on-chain registry is like a directory of available computing resources, with info crucial for carbon-aware decisions. It’s also transparent — anyone can see which nodes are available and where they are.
• Green Nomination Process: When a workload needs scheduling, a separate group of decentralized nominators, independent from the compute nodes themselves, evaluates the available options. These nominators analyze live carbon intensity data (from step 1), assess each node’s performance and capacity, and rank them based on sustainability. Essentially, the nodes compete, but not on price or speed alone, on verifiable carbon performance. The system then nominates the best-suited, lowest-carbon node to execute the task, ensuring a trustless and tamper-proof selection process.
• Workload Execution & Proof: The chosen node runs the computation. During and after execution, it logs the energy used and the carbon intensity at that time. This information is reported back and recorded (for example, as an attestation on Energy Web X). The result is a verifiable proof that “Task X was executed at Time Y in Region Z with carbon intensity Q gCO₂/kWh.” If someone doubts the claim, the proof is on the blockchain for anyone to verify.

Continuous Optimization: Over time, the system can employ incentives to improve efficiency. For instance, node operators who consistently provide low-carbon compute (by perhaps adding their own renewable energy or load-shifting) could be rewarded. Likewise, if the network notices certain regions becoming cleaner (say a new wind farm installed), it will naturally start shifting more workloads there. The feedback loop encourages the whole ecosystem to move towards cleaner operations, as sustainable nodes get more business.

In practice, this means a company using Carbon-Aware Nomination could submit a batch job and know that the job will run at the best possible time (perhaps an hour later when a green energy surge comes) and in the best location (maybe on a server one country over where it’s a windy night), all without manual intervention. The heavy lifting of “when and where to compute” is handled by the decentralized logic in a transparent way.

How Carbon-Aware Nomination Fits into Energy Web X

Carbon-Aware Nomination is a component of the broader Energy Web X (EWX) ecosystem. EWX is Energy Web’s new architecture for decentralized solutions, and it supports multiple “nomination” methods (i.e., scheduling and matching mechanisms) for every single compute workload of their solutions. Carbon awareness is one powerful approach, but not the only one — some applications might optimize purely on cost or latency, for example. Within EWX:

• Solutions can opt-in to Carbon-Aware Nomination if minimizing emissions is a priority, or choose other nomination modules better suited to their needs. This flexible architecture means EWX can cater to different preferences (greenest vs. fastest vs. cheapest, etc.), and Carbon-Aware Nomination is available for any solution that cares about sustainability.
• Even for applications that prioritize performance, Carbon-Aware Nomination can run in the background or as a secondary filter. For instance, if two nodes are equally capable, why not pick the one on cleaner energy? In this way, the carbon-aware mechanism can enhance other scheduling strategies by adding a sustainability lens.
• All of this happens while leveraging the security and transparency of Energy Web’s blockchain. The nominations (scheduling decisions) and the resulting proofs are recorded on-chain, which aligns with Energy Web’s mission to use open digital infrastructure for the clean energy transition. EWX provides the trust layer that makes Carbon-Aware Nomination’s claims audit-proof.

Decentralized Nomination: Trustless, Transparent, and Resilient

Unlike a traditional cloud scheduler (where one company’s software decides where your job runs), Carbon-Aware Nomination operates without a single controlling entity. The decision process is distributed among many participants and governed by open algorithms. This decentralized approach brings several advantages:

• Trustless operations: You don’t have to trust Energy Web or any cloud provider’s claims — you can verify the outcomes yourself on-chain. If a workload was supposed to run on green power, anyone can check the records and confirm it did. This is crucial for companies that need to report emissions reductions to regulators or want to avoid greenwashing.
• Transparency: Every step, from the carbon data used to the final selection of a node, can be made transparent. Community members could even watch a dashboard of live nominations happening, seeing in real time how the system is chasing the lowest-carbon resources. This level of openness is unheard of in proprietary cloud scheduling.
• Resilience: Decentralization also means there’s no single point of failure. The nomination process can continue even if one node or one data feed goes down. Multiple nodes participate in making decisions, and the blockchain ensures a canonical record. It’s much harder to corrupt or game the system — doing so would require attacking a broad, global network of participants.

For users, this simply translates to peace of mind. You get a robust service that not only optimizes for sustainability but is also inherently reliable and tamper-proof.

Why Open Source Matters

Energy Web is committed to open-sourcing the entire Carbon-Aware Nomination system. By making it freely available to developers, enterprises, and even competitors, we aim to set a new industry standard for carbon-aware computing. Transparency is a core value here — anyone can inspect the code to understand how decisions are made and suggest improvements. Open source also accelerates innovation: a global community can adapt the tool for new use cases (imagine carbon-aware scheduling for edge devices or for other batch processes like rendering and scientific computing). We’re releasing this under an open license so that this carbon-aware logic can proliferate everywhere, not just within Energy Web’s ecosystem.

Ultimately, climate change is a shared challenge. We believe that by open-sourcing this solution, we enable network effects — more contributions, more adoption, and more emissions saved. No single company can decarbonize IT on its own, but together, we can make carbon-aware computing the “new normal” for all data centers and devices.

Join the Movement

Carbon-aware computing is the future. Whether you’re an enterprise managing thousands of servers, a blockchain enthusiast, or a developer hacking on weekends, you can start integrating Carbon-Aware Nomination into your workflows to make a tangible impact. This isn’t just an Energy Web project — it’s a call to all cloud providers, decentralized network operators, and software platforms: join us in running workloads on clean energy. Imagine a world where every AI training, every render job, every transaction validation automatically seeks out the greenest energy available. That’s what we’re building, and we invite you to build it with us.

The code will be open-sourced on Energy Web’s GitHub (and accessible through our developer portal). We’ll be hosting community calls and tutorials for those who want to implement it or contribute. By working together, we can ensure that the digital infrastructure of the future not only powers our economies — but also heals our planet. It’s time to decarbonize the cloud, one workload at a time.

Carbon-Aware Nomination System for Decentralized Computing is now live was originally published in Energy Web on Medium, where people are continuing the conversation by highlighting and responding to this story.

Zug, Switzerland & Oakland, CA — April 3, 2025 — Energy Web, a global nonprofit building open-source Web3 technologies for the energy transition, WattTime, an environmental tech nonprofit providing real-time grid emissions data, and the Green Software Foundation (GSF) today announced the launch of Carbon-Aware Nomination, an open-source system for scheduling computing workloads based on electricity carbon-intensity. This first-of-its-kind solution leverages GSF’s Carbon-Aware SDK, blockchain technology, and live emissions data from WattTime to ensure that applications run when and where power is cleanest, drastically reducing the carbon intensity of computing workloads.

A New Standard for Carbon-Aware Compute

Carbon-Aware Nomination combines Energy Web’s decentralized computing platform with WattTime’s Automated Emissions Reduction (AER) data feeds and GSF’s Carbon-Aware SDK, allowing any batch job or flexible workload to automatically “chase” the lowest-carbon energy available. Instead of running immediately or in a fixed location, a task can be delayed or relocated — for example, executing at night in a region with abundant wind energy — with the entire decision process orchestrated and verified on the Energy Web X blockchain. Unlike traditional cloud computing tools, this system provides cryptographic proof of the carbon emissions caused, giving enterprises and developers unprecedented transparency into the sustainability of their IT operations.

“Our community has been looking for ways to cut IT emissions without sacrificing performance or trust,” said Mani Hagh Sefat, CTO of Energy Web. “Carbon-Aware Nomination delivers that by leveraging decentralization. By partnering with WattTime and integrating GSF’s Carbon-Aware SDK, we’re injecting the best real-time data into an open, trustless network of computing resources. The result is a game-changer — any organization can now ensure its workloads run with the lowest possible carbon impact, and they can prove it. We’re excited to open-source this tool and work with others to scale it up; this is about creating a new norm for green computing across the industry.”

Collaboration Across Climate-Tech Innovators

WattTime’s leadership echoed the significance of this collaboration.

“This partnership demonstrates how data and technology can come together to fight climate change in new domains,” said Gavin McCormick, WattTime co-founder and Executive Director. “Energy Web’s innovative use of our emissions intelligence, coupled with the Green Software Foundation’s Carbon-Aware SDK, ensures that even computing workloads can automatically prioritize clean energy. We’re thrilled to see Automated Emissions Reduction principles expanding into cloud and blockchain infrastructure. By giving organizations the power to run tasks when renewables are abundant, Carbon-Aware Nomination turns climate intention into action.”

The Green Software Foundation (GSF), which has been advancing sustainability in software development, also sees this as an important milestone. “GSF’s mission is to reduce the environmental impact of software, and integrating our Carbon-Aware SDK into decentralized compute systems represents a major step toward that goal,” said Asim Hussain, Executive Director of Green Software Foundation. “By working with Energy Web and WattTime, we’re proving that sustainability can be a core part of modern computing — measurable, verifiable, and open-source.”

An Open-Source Future for Climate-Smart Computing

The Carbon-Aware Nomination system is fully open-source, with documentation and developer tools provided by Energy Web. Companies and developers can integrate it into cloud workflows, decentralized applications, or scheduling software to begin reducing the carbon emissions of their operations. Because the solution runs on a public blockchain, any sustainability claims are transparent and auditable by third parties.

This initiative also aligns with broader efforts by the tech sector to cut emissions: recent studies estimate that data centers and networks account for over 1% of global electricity use, and industry leaders are keen to mitigate this impact.

By launching Carbon-Aware Nomination in collaboration with WattTime and the Green Software Foundation, Energy Web aims to foster an ecosystem of climate-smart computing. The three organizations plan to engage cloud providers, enterprises, and researchers in adopting the approach. This joint effort showcases the power of cross-sector partnerships, bringing together blockchain-based decentralization, real-time environmental intelligence, and software-driven carbon-aware scheduling.

The International Energy Agency recently released two reports: its annual Electricity 2025 analysis and a discussion of current challenges in grid investment. These documents describe two key aspects of the global energy transition: global demand for electricity is increasing, and new renewables (including distributed energy resources) are expected to be the greatest contributor to new supply that meets it. If you dig a bit deeper, you can also see why the electricity system needs a Digital Spine, Energy Web’s solution to optimize grid flexibility and unlock the potential of DERs.

The energy transition continues

The IEA forecasts “soaring” electricity demand over the next three years. Most of this increase will occur in developing economies, but advanced economies are expected to see increasing demand as well, driven by electric vehicle adoption, new air conditioners, heat pumps, and (especially in the U.S.) new data centers.

This new demand will be met by new low-carbon generation. The IEA expects fully half of the new demand to be met by solar PV, the cost of which continues to decline.

But progress increases complexity

It is undoubtedly excellent news that low-carbon generation will meet new demand, but the IEA cautions that power systems need to further adapt to the changing fuel mix on our grids. A combination of traditional thermal plants that are relatively inflexible, new renewable generation that is variable, and new demand patterns (e.g., more air conditioning demand on hot days and more electric vehicle charging on workday evenings) result in higher volatility in power markets.

We already see these impacts. The Electricity 2025 report describes the increasing incidence of negative prices in wholesale electricity markets, which occurs when supply outsizes demand so significantly that market-clearing prices fall below zero. This can happen for any number of reasons, but as the energy transition continues we would expect to see it happen more frequently in areas where afternoon solar generation could far exceed air conditioning demand (think massive amounts of rooftop and utility-scale solar) or overnight wind generation is greater than nearby transmission capacity.

Negative pricing events are most common in the regions of the world that are furthest along the energy transition, including Australia, California, and Texas (three places with very high solar PV or Wind penetration).

Negative price events are not in themselves a problem; however, they are noteworthy because they suggest real challenges in power system operations, which will only increase as the energy transition continues.

Physical infrastructure improvements will be insufficient

One strategy to address these challenges is to increase investments in electric grids. This means increasing transmission capacity and upgrading other physical infrastructure in order to reduce constraints that contribute to negative pricing: if one location has more power supply than demand, simply ship the excess to a location that can use it (yes, we recognize that this simplified description glosses over the complexities of constrained dispatch, but it remains true that increasing capacity in an appropriately-planned way will reduce the impacts of system constraints).

Unfortunately, the IEA does not think such new investments will be sufficient, or at least not sufficiently fast:

Around 1.5 million kilometres of new transmission lines have been built worldwide over the last decade, but inadequate transmission remains major constraint on power system development, electrification and energy security. Among other issues, grid infrastructure has struggled to keep pace with the rate at which new renewable sources are entering the system.

Their report describes several reasons for this, including supply chain bottlenecks and permitting delays — problems that are unlikely to recede in an era of increasing trade protectionism.

Managing power systems requires new ways to provide flexibility

So if new transmission is insufficient, what is the solution? The IEA offers its perspective: “Optimising the use of existing grid infrastructure through digital technologies enhances efficiency and maximises the use of existing assets, providing a safety valve for networks and supply chains”

This is precisely what our Digital Spine solution does: facilitate integration of DERs to allow grid operators and market participants to efficiently, fairly, and securely operate the grid. It can wring cost savings out of existing operational processes or even allow new market configurations that until now have not been feasible.

As an example of the latter, we implemented our Digital Spine solution in Australia as part of the Australian Energy Market Operator (AEMO)’s Project Edge. In that project, AEMO and market participants demonstrated a new approach to integrating DERs into both transmission- and distribution-level operations: a two-sided market based on dynamic operating envelopes. An independent cost-benefit analysis found that implementing this approach could save consumers AU$5–6 billion over twenty years, and that the savings would accrue to both consumers with DERs and those without them. A separate independent technology and cybersecurity assessment found that the Digital Spine as the underlying data exchange was more scalable, stable, resilient, flexible, and secure than traditional point-to-point or centralized approaches.

If you or your organization are looking to increase your network’s efficiency and unlock the full potential of DERs, please see our Digital Spine webpage for more information or to contact us.

The energy industry is at a turning point. With decentralization on the rise, evolving regulatory demands, and an urgent push for sustainability, industry leaders must innovate together. That’s why Energy Web is excited to launch Energy Web Circles — a new initiative that brings together enterprises, regulators, and technology providers to create software solutions for today’s energy challenges.

A New Model for Collaboration

Energy Web Circles are designed to cut through traditional silos by focusing on key issues faced by the energy sector. Each Circle zeroes in on a specific challenge or opportunity, ranging from decentralized identity management, zero carbon electric vehicle charging, to carbon-aware computing and advanced grid management. These groups offer structured, flexible environments where participants can create solutions, share insights, and help shape emerging industry standards.

Introducing the First Circle: Universal Energy ID

Our inaugural Circle, Universal Energy ID, sets the stage for a more secure and interoperable energy ecosystem. As energy markets become increasingly decentralized, the need for a transparent and standardized identity framework grows. The Universal Energy ID isn’t just an identity solution — it’s a trust layer for the decentralized energy economy. It enables secure, seamless, and interoperable transactions that are essential for modern energy systems.

What is the Universal Energy ID Circle?

The Universal Energy ID Circle is a collaborative initiative aimed at developing and deploying a decentralized identity and credentialing system for the energy sector. The primary goal is to create a trusted and verifiable identity infrastructure that enables seamless transactions, regulatory compliance, and secure access control across the energy ecosystem. The Circle is designed to foster the development and integration of the EnergyID framework to enable Digital Product Passports (DPPs), e.g. to manage the lifecycle of batteries. For a DPP, this means that information about a product can be stored and updated across a network of various participants (manufacturers, suppliers, distributors, consumers, regulators) without relying on a central entity, making it resistant to censorship and single points of failure. By implementing DPPs, enterprises can drive innovation in electric mobility, enable circular economy practices, and comply with evolving regulatory requirements.

What Does the Solution Look Like?

At the core of this initiative is the EnergyID DID method, a W3C-compliant Decentralized Identifier (DID) specifically tailored for energy applications. This method provides a secure, tamper-proof way to authenticate energy-related assets, organizations, and individuals. This framework empowers electric mobility providers, distributed energy resource (DER) operators, and digital product passport managers to build trust and security into their transactions, setting a new standard for the industry.

The solution comprises:

• Universal EnergyID Wallet — A digital identity wallet that allows energy stakeholders (such as utilities, DER owners, and EV users) to store and manage their decentralized identifiers and verifiable credentials.
• Verifiable Credentials (VCs) — These digital attestations enable secure proof of identity, asset ownership, and regulatory compliance in energy transactions.
• Interoperability Layer — Designed to integrate with existing identity management systems and ensure compatibility with global standards such as eIDAS 2.0.
• Trust and Governance Framework — A decentralized governance structure ensuring that credential issuance and verification are secure, reliable, and universally accepted.

How It Works in Practice

• For Electric Vehicle Charging: EV owners can use their Universal EnergyID to authenticate at any charging station, ensuring trusted, frictionless access without relying on siloed authentication systems.
• For Distributed Energy Resources (DERs): A solar panel or battery storage unit can have a unique, verifiable identity that allows grid operators to authenticate its participation in energy markets.
• For Energy Data Sovereignty: Consumers can control who has access to their energy data, ensuring privacy and security while enabling seamless energy transactions.
• For Regulatory Compliance: Businesses and energy providers can automatically prove adherence to compliance standards through digitally signed verifiable credentials.

Key Benefits of Universal Energy ID

• Unified Identity Management: It provides a single standard for managing identities across energy, electric mobility, and beyond, eliminating fragmentation.
• Proven Adoption: Major enterprises and OEMs are already adopting this framework, demonstrating real-world traction.
• Regulatory Alignment: Built to align with standards like eIDAS and Digital Product Passports, it ensures both compliance and scalability.
• Open and Interoperable: The solution is integrated with leading open-source identity frameworks, including OWF and ACA-Py, making it adaptable to various use cases.
• Secure Communication: Worker nodes in Energy Web act as DIDComm mediators and relayers, ensuring secure, reliable communication in decentralized identity ecosystems.
• Automated Billing: The system supports automated and trustworthy billing for energy consumed and produced, reducing administrative friction

Why Katalist?

Decarbonizing the maritime industry is a challenging task due to the long lifespan of ships (around 35 years), which limits the speed of fleet replacement. This is why the focus has shifted to the use of low-emission fuels, enabled by a Chain of Custody model called “Book and Claim.”

The system allows for the decoupling of the physical low-emission fuel from its associated low-emission attribute, which can be traded separately. This approach makes low-emission fuels more accessible.

This model serves as an interim mechanism, buying time until global infrastructure is fully in place to support widespread physical use of low-emission fuels without needing to decouple the sustainability attributes of maritime fuel from its actual usage.

How?

To build trust among participants, the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping and RMI have co-developed and continuously refined a robust methodology that all actors can rely on.

The role of Energy Web Foundation was to provide the technology platform in a way that shortened implementation timelines, enabled hypothesis testing, and allowed for necessary adjustments in a relatively short time compared to building everything from scratch.

Thanks to our Generic Green Proofs approach, we successfully developed two proof-of-concepts, gathering valuable insights that enabled the team to refine the solution into a full production platform — ready to launch in November at COP29 (link to the press release).

What might have taken years to build, we accomplished in months, delivering critical insights that shaped the final platform.

What Companies Can Do on the Platform

1. Issuance
   The creation of certificates on Katalist follows a well-thought-out methodology. This ensures that the most relevant data is collected from ships and voyages, along with the appropriate documentation to attest to fuel attributes and usage.
2. Transfer
   Participants on the platform can transfer certificates based on predetermined rules and restrictions.
3. Retirements and Export (Claims)
   The ultimate goal for companies using the platform is to claim emission savings from alternative fuel usage in their sustainability reports.
4. Public Retirement Table
   Depending on the type of company, industry actors can view varying levels of information about actual fuel usage. Once the final actor (Cargo Owner) has claimed the certificate, the data becomes publicly available through the “Public Retirement Table.”

Who?

The platform is designed for key maritime industry actors:

• Shipping Companies: Operators or owners of ships are responsible for purchasing fuel and uploading relevant data to the platform.
• Freight Forwarders: Intermediaries in the maritime transportation cycle and vital parts of the supply chain.
• Cargo Owners: Responsible for the contents of shipments.

What Will 2025 Bring?

By the end of the year, we anticipate onboarding several companies to the platform. By early 2025, the first certificates will be issued using Katalist. Additional features will be developed, with updates shared as plans progress.

Conclusion

Energy Web contributes to decarbonization efforts by serving as a climate-tech partner, significantly accelerating the journey from ideas to proof-of-concepts and minimum viable products.

Our expertise lies in creating generic frameworks that enable faster deployments, adaptable to decarbonization plans that drive impactful climate change solutions.

If you’re interested in bringing your ideas to life faster and more efficiently using proven methodologies and connections with relevant industry actors, let’s discuss how Green Proofs can be applied to your use case. contact us!

Generic Green Proofs Use Case (Applied to the Maritime Industry): Katalist was originally published in Energy Web on Medium, where people are continuing the conversation by highlighting and responding to this story.

Why Green Proofs?

In today’s world, corporations are under immense pressure to reduce their carbon footprints, meet regulatory standards, and fulfill consumer demand for greener products. In doing so, they must balance the challenge of providing good and verifiable data that stands up to external scrutiny with protecting their proprietary information and processes.

Corporations are pursuing a variety of sustainability solutions to achieve these goals, which vary in terms of flexibility, cost and compliance with the standards of large-scale enterprises and regulators.

To address these complex sustainability needs, Energy Web developed Green Proofs — a powerfully comprehensive and configurable software solution — to bring deep levels of transparency and verifiability to emerging green products and markets.

Green Proofs technology is built to enable the following:

1. Buy and sell low carbon services and commodities: Whether your company deals in biofuels, green energy, or climate-conscious services, Green Proofs helps you sell and source products that can be verifiably marketed as sustainable.

2. Launch green product registries: Create transparent, scalable, and credible market access in “hard to abate” sectors that can benefit from attribute tracking and support broader decarbonization.

3. Prove your company and products are sustainable: Green Proofs provides tools for tracking and reporting progress toward environmental goals. It integrates granular data, helping you measure Scope 3 emissions and evaluate supplier impact while protecting sensitive information.

Green Proofs technology

Green Proofs is a suite of modular technology solutions that come in the form of turn-key applications or highly customized software built in close partnership with Energy Web.

A core technology underpinning Green Proofs software is the Energy Web Worker node network. Energy Web developed worker nodes to solve a longstanding problem that hindered the advancement of energy tracking solutions: solution logic varied widely according to use case and relied on commercially sensitive data that oftentimes needed to remain private, but the results needed to be transparent and publicly verifiable.

Worker nodes address this problem by allowing enterprises to configure their own computing networks that:

1. Ingest data from external sources
2. Execute custom logic workflows
3. Vote on results in order to establish consensus without revealing or modifying the underlying data.
4. Publish the consensus to a trusted, public ledger

Worker nodes put enterprises in the driver’s seat of their application, giving them granular control over workflow logic and data inputs. The end result is an enterprise-friendly architecture that provides cryptographic proof that pre-defined rules and processes are being followed correctly, while preserving data privacy and integrity.

It is important to note that while Energy Web has historically been known for its use of blockchain, worker nodes do not exist to store or tokenize certificates and data on the blockchain. The primary use of blockchain in Green Proofs is to serve as a ledger for the worker nodes’ validation results of logic workflows.

Green Proofs Business Applications

Green Proofs helps companies demonstrate that their operations, products, and services are sustainable. It achieves this in three ways:

Helping Companies Buy and Sell Low-Carbon Services and Commodities

Green Proofs streamlines access to low-carbon services and commodities, empowering companies to source materials and services that both support their sustainability goals and enable the marketing/sale of verifiably green products. Currently, Green Proofs is streamlining market access to sustainable aviation fuel, green EV charging, low-carbon shipping services, and climate-aligned Bitcoin mining, making it easier for companies to find the right solutions to reduce their Scope 1, 2, and 3 emissions.

The recently-announced Katalist platform is an excellent example of this business application — using Katalist, maritime freight customers can lower their emissions using a robust book-and-claim system, supporting corporate sustainability claims about themselves and their products.

Launch Green Product Registries

For companies or consortia looking to establish or expand markets for emerging green commodities, Green Proofs offers the ability to launch next-generation Green Product Registries. These registries support transparent, scalable tracking of sustainable goods and services, enabling participants to securely book, trade, and retire digital certificates that represent specific environmental attributes.

By deploying these customized registries, companies can support sustainable product verification, drive growth in emerging green markets, and contribute to decarbonization efforts on a larger scale. With the flexibility and transparency offered by Green Proofs, businesses can lead the way in expanding sustainable options for their industry while building trust with customers and stakeholders.

To learn more about this business application, we invite you to explore the SAFc Registry, where users can obtain certificates representing the use of sustainable aviation fuel, which are then used to credibly claim Scope 3 emissions reductions.

Track and Report Emissions

To truly demonstrate sustainability, companies need more than metrics; they need verifiable data that tracks the environmental impact of their products, operations, and supply chains (scope 1, 2 and 3 emissions). Green Proofs can help companies better collect, track, and report this data in detail, offering insights on both corporate-level and product-specific emissions. We are currently working with industry partners to gather requirements for this business application .

Who can use Green Proofs?

Energy Web built Green Proofs for any corporation or organization that wants to market itself or its products as green. We help customers access Green Proofs in a variety of ways — from no-code and low-code solutions that enable quick, independent launches to providing ongoing design, development, and hosting services for bespoke platforms.
