Open source windmills in Mali - using waste materials

Fri, 17 Sep 2010 01:59:00 -0700

Meet Piet Chevalier. He is a wind power engineer and decided to help people to build their own windmills.
Local people [Mali, Tanzania] are trained in building a windmill using waste materials and using a limited range of tools.

Google's nerd search engine

Wed, 15 Sep 2010 08:57:46 -0700

Google Squared builds a table of facts for the search terms you enter.
It formats your search results in spreadsheet format, which immediately appeals to us data nerds.

The supreme geek search engine is still WolframAlpha which managed to invent its own category: the computational search engine.

Interest in climate change back to pre-2007 level

Tue, 14 Sep 2010 07:37:12 -0700

How often do people search on "climate change" on the web? Google trends has the answer.

Whatever the weather: warning for business

Mon, 13 Sep 2010 05:24:57 -0700

British business organization CBI has issued a report warning companies to take climate change risks for their business into account.

For example, climate change risks assessment should cover six key areas – supply chains, assets, operations, markets, regulatorycompliance and business reputation.

Magic disappearance trick of UNFCCC's emissions

Fri, 10 Sep 2010 06:43:00 -0700

The Secretariat of UNFCCC published a carbon footprint of its activities in 2006, covering 2004 and 2005. That footprint contained multiple material errors and has been removed from the UNFCCC website.

The greenhouse gas emissions of UNFCCC were about 25,000 tCO2 per year. In the 2008 carbon footprint this has apparently been reduced to 1,687.2 tCO2.

How did they do it? I mean, even if you offset the emissions they still occurred. Did they ground all staff? Do they have their own fleet of biofuel-powered airplanes?

Note also the precision - in 0.1 tCO2. Emission factors of IPCC have only 3 significant digits, and therefore the calculated CO2 emissions cannot have more than 3 significant digits either.

ISO guidance for carbon footprints adds new complexity

Thu, 09 Sep 2010 06:32:43 -0700

The advantage of ISO 14064-1 [*] is that it is much shorter than the 116 page GHG Protocol. The disadvantage is that the extra explanation is required because it is so short, and therefore ISO is now working on a guidance document: ISO 14069.

One of the things where ISO is providing guidance on is scope 2 emissions - the CO2 that is related to the electricity that you consume but that was not generated on your site. In the GHG Protocol approach you just take IEA emission factors. ISO proposes something much more complex. The mechanism is not clear yet, but involves something with type of electricity mix and consumption profile [level 1 and level 2]. Then, the reporting company can choose between taking into account all electricity, or only the mix of the most competitive technologies of the electricity market [attributional or consequential approach].

I needed to sit down with a glass of milk after reading this. It does not make carbon footprinting clearer or simpler. It also increases the choices for companies and therefore makes comparisons between footprints more difficult. Over the last 10 years I did not meet many companies that would be willing to go into this sort of detail for estimating their scope 2 emissions. So this whole idea of estimating scope 2 emissions seems like something for the ideabox.

CDP proposes "financial control plus" reporting

Tue, 07 Sep 2010 23:47:33 -0700

CDP proposes that reporting companies report their greenhouse gas emissions on the basis of financial accounting rules. At the moment companies can choose between consolidation approaches [financial control, operational control, equity share] when applying ISO 14064-1 or the GHG Protocol. The consequence of this is that carbon footprints of companies are often not comparable.

The proposal of CDP is that companies report 100% of the emissions over the companies under financial control. This includes leased assets. Joint ventures and participations report greenhouse gas emissions according to the percentage interest or equity share.

The Carbon Disclosure Project requests information on greenhouse gas emissions and climate change strategies to 4700 of the planet's largest companies every year.
It does so on behalf of 534 institutional investors with a combined $64 trillion in assets under management.

CER issuance times continue to rise

Sun, 05 Sep 2010 13:08:34 -0700

The UNFCCC website contains a list of the 1799 issuances that took place sofar.

The time between end of monitoring period and the issuance has risen to 300 days [median]. Of these 300 days, the project developer needs about 30 [waiting for the final data to become available, writing monitoring report]. The remaining 9 months are spent in the verification and the UNFCCC system.

The monitoring reports of the last issuances were written 6 - 9 months ago; new Executive Boards procedures introduced in the last few months may further slow down the issuance process.

Making carbon footprints comparable

Fri, 03 Sep 2010 04:54:59 -0700

The standard for carbon footprinting is ISO 14064-1. It is more or less a summary of the WBCSD/GHG Protocol. The problem with this standard is that it does not lead to standardized, comparable carbon footprints. This is because the standard leaves important choices open to the user. One of them is the way the user selects emission sources to report from - the organizational boundaries. The other is the way scope 3 [other indirect] emissions are reported - the operational boundaries.

Organizational boundaries: You can choose between a "control approach" and "equity share". In the control approach you report 100% of the emissions from sources over which you have financial or operation control. In the equity approach you only report the your portion of the facility - if you own 20%, you report 20%. In the equity approach you also report zero emissions for leased assets, since you don't own them. Imagine a bank with a leased office and leased cars. Their emissions will be zero in an equity share approach, whereas they would be fully reported in an operational control approach.

Operational boundaries: You can choose to not report scope 3 emissions at all. Most of the companies that do report scope 3 emissions limit the categories to commuting and business travel. Normally, mapping scope 3 emissions leads to [1] a lot of work collecting data with large associated uncertainties and [2] dwarfing of your scope 1 and 2 emissions. For example, the use of your Apple computer represents more than half of the greenhouse gases that can be associated with Apple.

What is being done about this? The carbon disclosure project [www.cdproject.net] is proposing that companies report using the financial control approach. ISO is working on a standard that gives further guidance to the application of the standard [ISO 14069, draft]. The WBCSD/WRI is working on tools for better assessment of scope 3 emissions [www.ghgprotocol.org]. For the time being you will have to take a very good look at the details of the carbon footprint of an organization before you start comparing.

Registered CDM projects per 2 September 2010

Thu, 02 Sep 2010 02:04:47 -0700

You can download any table on a website straight into Excel 2007 using the /data/from web option. I have downloaded all the registered CDM projects from the UNFCCC webpage and visualized them.
The request for review status applies to registration. There are big HFC projects now for which a request for review has been submitted.

IPCC emission factors tool

Wed, 01 Sep 2010 23:16:00 -0700

fuels.swf Download this file

When you start using IPCC 2006 emission factors, you will see immediately that the units are unwieldy.

That's why I created this tool that allows you to select a fuel and get the emission factor in all the units you want.

You can also use the slider to set a generation efficiency for combustion.
In that case, the tool produces the tCO2/MWh that is related to generating power or heat at that efficiency.
