CDM for fly ash and brokers, against recycling and the poor of Delhi

2008-08-06T18:55:52+01:00

I know that this blog is shutting soon but I wanted to write a tiny last post before it dies out...
I just read an interesting article about the negative effects CDM (Clean Development Mechanisms - a scheme under the Kyoto Protocol) can have on both the local environment and the poor, but how on the other side they can benefit some opportunist and unscrupulous brokers and developed countries playing this game.
http://www.motherjones.com/news/outfront/2008/07/outfront-wasted-potential.html

I don't want to generalise about CDMs as I am (pretty) sure there might be some good projects, and I don't mean that Delhi's situation is brilliant thanks to waste-pickers! I just wanted to highlight an interesting example showing that too narrow boundaries for the evaluation of a project as well as stakeholders looking for easy money usually lead to ill-advised decisions (quite obvious, isn't it?).
Happy reading and good luck with y(our) PhDs or whatever you are doing!

But Darling! What about the pain at the pumps?

2008-07-23T00:15:14+01:00

This is a couple of weeks old now, but I feel it may still be worth discussing. In light of Alistair Darling's shockless u-turn on fuel duty this month, the Tories have been grandstanding around the place with their big ideas for 'sharing the pain' of high oil prices. According to George Osborne their so-called Fair Fuel Stabiliser would operate "so when the price of oil goes up, fuel duty would actually be cut. And with duty rising when oil prices fall, we would be putting something aside in the good years to help in difficult times."

Aside from the fact that I'd like Mr Osborne to square this shameless price-control policy with his usual free market rhetoric, I'd like to know if it could ever work. Aside from the fact that we all know this is probably 75% opoprtunistic politics for the Daily Mail consensus, could they really save the pence they claim and stil raise revenue?

The Tory maths department says that:

"had the Fair Fuel Stabiliser been introduced in the 2008 Budget, when unleaded petrol cost £1.08 a litre, then half of the 10p rise since then would have been absorbed by government."

But, as Vince Cable says in the same Time article, Mr Osborne may be:

"presuming a knowledge of future trends in oil prices which is not shared by most people who look at these professionally"

So, let's see what would have happened at an earlier point in time. In 2000 the tripling in oil prices from $10 to $30 brought protesters out on the British streets to complain at the pump price of petrol. The Conservative Party had campaigned for protests against Labour's fuel duty rises and the ensuing blockades created much more havoc than the one-lane whimpers we've had this year. So it might have been an ideal time to instigate some kind of Fair Fuel Stabiliser. But no good years came (see graph of data from the US via the EIA - sorry, didn't have time to find UK figures).

The truth is that until now the economy was sufficiently buoyant to absorb the rises in oil prices. Economic growth was outpacing the increases in pump price as a high tax buffer heavily shields the consumer from the full proportional crude price rise.

Oil prices have begun to soften recently, apparently due to a relaxing of political tensions in oil states. If a tax cut plus a flexible tax rate were introduced today by a new Tory government (surprise!) then maybe Mr Osborne would be able to raise duty a little later in the year. But given the last 8 year's trends I wouldn't bet against prices continuing upwards (albeit more slowly), thus effectively demanding a rising subsidy. Or am I mistaken?

Another aspect to this is that the fuel price protests mostly arose from concerns from lorrydrivers about Johnny-trucking-Foreigner's comparitively cheap oil, which he can bring over here in his extra fuel tanks from dark places in Eastern Europe where fuel duty is less high (hmmph). Mr Osborne's Fair Fuel Stabiliser would most likely still be unfair in this regard, especially in the 'fat' years as the Tories promise to keep duty up at a bearable level for environmental reasons.

If there's a message to all this nonsense then it might be that it would be nice if politicians recognised that fuel duty hikes are a pretty minor component of pump price, and are generally absorbed by an economy over time. (Hence the most potentially important act in amongst all the politicking recently was Brown's visit to the House of Saud). Even better (wishful thinking alert!), maybe policies could be a bit more explicit about which element of the tax is related to environmental externalities, and which is for the general coffers. Hey, and while we're talking about wacky ideas, why not suggest tackling GHG emissions from transport solely through a pump price that incorporats a pan-European carbon price reflective of the marginal abatement cost? Or is that too liberal for the Conservative Party?

This is the End... of sorts

2008-06-29T00:57:58+01:00

As those of you following the blog have no doubt noticed, the regularity of the posts in the last few weeks has slowed to a snail's pace. The reason for this is that we are all getting on with our PhDs - either attempting to upgrade or writing up - and finding less time to contribute. Myself included; I have found it difficult to balance my PhD and professional work time with researching and writing blog posts.

As such, there will likely be some changes coming to the site. This may include, unfortunately, closing down the blog for good.

It has been a good 18 months or so on the blog, and I think the rest of bloggers here will agree with me that it has been a real learning experience and a great project to work on. In particular, the blog has led me to read up on issues that I wasn't aware of previously, and forced me to have opinions on things to which I previously hadn't put much thought. And for that, I'm a better researcher. Of course, I can't not mention the Great Global Warming Swindle post, which was the watershed moment for the site. It brought a lot of new (and regular) readership, and without our audience (and commenters) the blog wouldn't have lasted this long.

So what next? I will be stepping down immediately as contributor to the blog, with the aim of soon stepping down as webmaster. I have decided that I would rather make a nice clean break from the blog, rather than let my internet presence peter away into (further) obscurity. I will be trying to find someone to replace me in charge of the day-to-day running of the site. If you are a PhD or MSc student here in CEP and are interested in doing so - get in touch! If I am unable to find someone, I will be shutting down the site.

Once again, many thanks to those who contributed to, read, and commented on the blog!

Perfect Payment for Ecosystem Services Scheme?

2008-06-23T17:51:28+01:00

A short while ago I was asked for an example of a perfect payments for ecosystem services (PES) scheme. A myriad of examples where things didn�??t quite work out came to mind and I had almost resigned myself to the fact that a perfect PES may not exist, when I found a report called �??The Vittel payments for ecosystem services: a �??perfect�?? PES case?�??

This Vittel case even received a mention in the recent The Economics of Ecosystems and Biodiversity (TEEB) report recently launched at CBD meeting in Bonn. This TEEB report has called itself the biodiversity equivalent of the Stern Review, aiming to evaluate the loss of biodiversity and the associated decline in ecosystem services worldwide. An ambitious aim, and the first phase report is disappointing but, since the Vittel case received a mention I was enthusiastic that I might be on to something.

Vittel is a very well known mineral water company; the UK consumes 80 million bottles a year. Originating at the base of the Vosges mountains in north-east France the water must be within quality requirements to call itself �??natural mineral water�??. Agricultural intensification in the areas surrounding the �??grande source�?? meant the Vittel brand name could be jeopardised if nitrate levels from fertilisers continued to rise. This was unlikely to be contamination to an illegal level, or dangerous level (nitrates in Vittel are 10 times less than tap water), but one that would damage the brand name; Vittel is characterised by a total absence of nitrites and low levels of nitrates.

To solve this potential loss of the brand name, Vittel created a PES scheme with local farmers. It abolished debt linked to land acquisition, provided subsidies to about 200 euros/hectare/year over five years, up to 150,000 euros per farm, free labour to apply compost to fields, and free technical assistance. All this plus long-term contracts to guarantee security for the farmers.

In this case study the link between the ecosystem service (water filtration) provided and the management practice was clearly scientifically established. There is one clear buyer, a number of sellers, and an effective intermediary institution. 100% of the farmers in the area accepted the 30 year contract and the scheme has eliminated 1,700 ha of maize land and kept Vittel as �??Vittel�??.

So it is, apparently, a successful example indeed, which is great. However, how replicable is this example? It took 10 years to develop, negotiate and implement this PES scheme involving only 26 farmers. All of parties were within close geographical proximity. Development included four years of intensive farm modelling and continuous on-farm testing. While there are no published total costs, Vittel spent 980 euros per hectare, per year, for the first seven years...

�?� will we be able to create similarly successful schemes for other ecosystem services when much of remaining forests and biodiversity is concentrated in developing countries? When deals are international? When we have more than 26 service providers? And, when there just aren�??t enough resources left to take ten years to develop a PES for a single watershed! I hope that such significant investments of time and money will decrease as markets for ecosystems services gain maturity and experiences like this will aid in future project development. But, for now, the search for the perfect PES continues.

Geothermal electricity as baseload

2008-06-06T10:59:00+01:00

Wind and PV are intermittent? Geothermal is not. Here we have a renewable source of energy which can be a good source of base load power.
Well it is still relatively expensive, but look what feed-in tariffs seem to be triggering in Germany.

Drilling is still the bottleneck for this technology (I remember hearing that last year at a Renewable Energy Association conference as well, from a representative of the UK geothermal "micro" industry).

However, (as happened for other technologies) such bottlenecks can usually be solved with investments and market expansion (as it is happening for the silicon feedstock bottleneck in the PV sector, as an example). This is maybe what it's happening in...Germany, again!

Personal carbon trading rises again!

2008-05-26T14:40:42+01:00

MPs have taken a break from proclaiming the death of the Labour party, and today lent their support to the personal carbon credit idea advertised by Ed Milliband 18 months ago. And when I say lent their support, I mean, they said the government should go ahead with it. Here is their report, released today.

Climate policy is all well and good, but I can't say I'm thrilled with this. I wrote about this proposal back in 2006 here, highlighting the fact that their proposed cap and trade system for individuals could be achieved with a tax and rebate ("feebate") scheme. But don't take my word for it: here is Greg Mankiw discussing a feebate in the NY Times last year. In my view, a feebate system avoids the costs and complexity of a cap and trade system, but retains the progressive nature.

But for those new to this discussion, I'll just summarize the issues. The idea is to reduce emissions from domestic energy and transport sources. The MPs from the Environmental Audit Committe (EAC) have proposed that this should be done via a cap and trade system, where each person in the UK is given an equal ration of carbon allowances, which can be "spent" on energy and transport emissions. Allowances that they don't use can be sold on a trading market, thereby offering an opportunity for income for people who are economical with carbon. These are generally people from lower incomes, thereby making the system progressive. Those who need more credits (or tourists) need to buy them from the market. The price of a permit represents the marginal cost of carbon reduction. A massive IT project to say the least - but supporters point to the Oyster card system to suggest it can be done.

A feebate system, on the other hand, places a fixed tax on the enegy and transport products on the basis of their embodied carbon. This incentivises switching to lower carbon products, much in the way as the permit price in a cap and trade system does. All revenue from the tax is then redistributed back uniformly to all tax payers. This means that more economical people are better off under the feebate system than before - which also makes the system progressive. This system, of course, requires transparency from the government.

Sadly, in all the UK government's material about personal carbon trading, I've not seen a convincing discussion about why it would be better than such a feebate. In today's EAC report, I find their argument weak.

For starters, they don't even compare trading with a feebate system - they compare it with green taxes without rebates (which we know are regressive). So they've skewed the argument in their favor to begin with. They also claim that, "We have been unconvinced of the Government�??s real commitment to implementing meaningful green taxation." (p.11). Which is a bit rich, coming from MPs.

They then claim:

[I]ndividuals are used to dealing with and absorbing price fluctuations from taxes, and need the provocation of a personal carbon allowance to make real decisions about their lifestyle.

[P]rice elasticity of energy consumption is very low in this [household] sector, which means that carbon prices would need to be very high to have a significant impact on behaviour and emissions.

Pray tell, what is the mechanism that incentivises carbon reduction under the personal carbon credit scheme? Could it be...PRICE?! How they seem to think that the price impacts under a personal credit scheme are more effective than a green tax is beyond me. This is Microeconomics 101: in theory, the impacts are identical, and their argument is bunk.

Now, I say "in theory" because it is possible that a useful advantage is that:

Cap and Share offers personal carbon trading�??s sense of empowerment and entitlement. (p.12)

There's a chance that it trading could make people more proactive because they can count their permits like beans. Now, this could make an interesting behavioural economics study, but the EAC have no such results to offer. As they admit, it is "not something we should have to rely on in order to implement a scheme" (p.13). Oh well.

Finally, they claim that the benefits of a personal carbon credit scheme over a tax system outweigh the costs. According to the BBC, "the cost of introducing the scheme would be between £700 million and £2 billion, and would cost £1bn-£2bn a year to run." (When I get further information, I'll compare these costs to their proposed emissions cuts.) I don't have estimates on the cost of a feebate system, but it would likely be implemented easily into the existing VAT and tax return system: no ID cards, no trading market, no mess.

So for now, colour me unconvinced.

Who are you calling a gas bag?

2008-05-26T13:52:12+01:00

I've been doing a little reading about an interesting little molecule called dimethyl ether, or DME. There are many who claim a bright future for DME as it can be produced from a variety of sources (fossil and renewable), it is a gas at room temperature but is easily liquified for transport, it is water soluble, and is a very clean-burning fuel for heating and in blends with LPG, petrol and diesel. It can also be converted to petrol and chemicals with high purity. Impressively for such a tiny molecule, it even has its own fan club called the International DME Association, who really would like to see more of it.

[Quick overview of DME production: It does not occur naturally in significant quantities and is made by the dyhydration of two molecules of methanol. Methanol is mainly made from syngas (carbon monoxide and hydrogen)]

Because DME burns cleanly and can be used in all existing engines it is attractive for car manufacturers (Volvo are in the IDA). Because it can be produced frombiomass gasified to syngas it is attractive to legislators (the EU is considering its use in biofuel blends). Because it can be made from coal it is attractive for countries that are short of oil (e.g. China) and coal gasification guys (Lurgi are in the IDA). But mainly it is attractive to oil and gas companies who are finding that natural gas is increasingly located further from its markets (Total and BP are in the IDA).

New Zealand went into production of methanol, DME and petrol from natural gas in 1979 to get value from remote gas fields, and whilst the petrol enterprise didn't survive the oil price collapse of 1986, methanol production did. Now Qatar is following suit with large-scale conversion plants to enable export of its gas as liquid fuels like diesel (via GTL). This is arguably more sensible than selling LNG, which has associated compression/decompression losses and is constrained by availablity of handling facilities. DME might be even better: it is has a 'clean' premium as a fuel, the conversion process has lower capex and opex costs and it can access additional markets such as LPG in Asia.

The problem with these kind of panacea technologies is that their attraction often hinges on the fact that they break the monopoly of a particular raw material, such as that of oil with transport fuel. So hydrogen, electricity and DME are all promoted on their ability to be produced fom renewables, but in reality are often backed by the suppliers of the fossil fuels from which they are more likely to be produced. In the case of DME, it seems that it offers something that hydrogen and electricity do not - it can bring an end to stranded natural gas fields for which pipelines and LNG are not practical - and if the IDA are persuasive enough, we can burn more fossil fuels as long as the crude price stays above $30 (er...likely...).

This post isn't really about whether its a bad thing to have more temptations to burn oil and gas in exciting new ways. It's more about how good ideas (e.g. waste/biomass to methanol to DME) tend to become overwhelmed and distorted once the big boys start to get involved in lobbying; I have no doubt that DME could be produced from renewable resources, but I question whether biomass features as heavily in BP's business plan for DME as it does in their presentations on the subject. In a roundabout way this brings me neatly back to the title of this post, which jumped out at me from a presentation by a BP technologist on DME.

In a list of different ways to get value from remote gas, Dr Fleisch mentions the 'very small niche' of Gas by Bag. Before I got carried away with my little introduction to DME (above), I was just intending to put up the pictures below and ask if anyone had any more info on Gas by Bag. It seems astonishing to me that this family have been given the facilities to fill a big old sack with unpurified methane and then just cart it home. I want answers!

Where do you think this is?
What can actually be done with gas at realtively low pressures, apart from poisoning and asphyxiation?
Is it free?
Why not install provisions for filling pressurised LPG bottles, which would be a 20th of the size for an equal quantity?

Watch that whale �?? it has a plastic bag on its head!

2008-05-21T16:31:29+01:00

Shamed by your pathetically un-environmental principles? Don�??t worry help is at hand �?? instead of getting free plastic bags at the supermarket, pay for them. Technically, you aren�??t actually saving the planet �??but you will be told you are - everyone wins. But thank goodness the one thing we are saving is as much oil as possible, what a relief!

Even Gordon Brown announced he would force supermarkets to charge for the bags, saying that they were �??one of the most visible symbols of environmental waste�??. Oh Gordon �?? you seemed to have confused �??environmental�?? with �??economic�??, mind you it�??s so easily done these days.

To my astonishment I discovered that even China plans to address their plastic bag use - at last are they growing a conscience? Well... maybe not, as they will save 37 million barrels of oil a year by cutting production. It certainly pays to care.

Selling Ecosystem Services: A pro-poor conservation solution?

2008-05-20T12:53:51+01:00

A meeting held by the Forests Philanthropy Action Network and the Department for International Development in London yesterday did well to bring a growing concern to the front of people�??s minds; just a shame that there were only a handful of people present.

The meeting, briefly covering the many issues of tropical forest conservation and the rural poor, focussed on the need for engagement of capital markets to realise the value of tropical forests. Academia, the public and private sector are beginning to promote this ecosystem service commoditisation as a method to not only conserve forests but also to reduce poverty in developing countries. On the surface it appears to make sense; depletion of natural resources and poverty often occur together. The development of a market generates revenue for previously �??free�?? ecosystem services. Deliver the funds to those who provide the service and you�??ll get poverty alleviation. But this seems more like an ideal, designed to help sell the idea to the policy-maker or consumer, rather than the reality.

Thinking beyond the lifespan of most well-meaning NGOs, will rural communities in developing countries have the capacity to deal with these markets for ecosystem services? Meeting conservation and rural development goals concurrently isn�??t straightforward. The Integrated Conservation and Development Projects, appearing since the 1980s, taught us that those living near to projects must have a high level of input in their design and implementation, and sufficiently clear links between conservation and social benefits must be made to secure success.

To take an example, consider payments made for CDM or voluntary carbon market projects in developing countries. It is highly unlikely that the average rural community will have sufficient capacity to deal with issues of additionality, leakage, permanence and management demanded by stringent compliance market conditions and emerging voluntary market standards. It is, arguably, just as unlikely to get private sector consultants and project developers to assess exactly what the local community�??s needs and aspirations are. It is more likely we�??ll try to implement projects claiming development benefits so that they sell and then shrug our shoulders as marginalised community members get poorer, or indigenous people lose customary property rights.

Those designing markets for ecosystem services need to carefully consider what the project is designed for. Is it compensation for the opportunities forgone? Is it to make tangible poverty reductions and contributions to development? Or, is it merely charity to the local communities that obscure potential implications of, for example, restricting resource access? If it is the first, we need much better ways to calculate opportunity costs before we do more harm than good. If it is the second, we must learn from community based resource management approaches and invest time and effort to establish best practice guidelines. If it is the third, then how long can we really get away with it?

Hey Mr Gore, what about meat?

2008-05-19T16:38:16+01:00

A whole movie on climate change without talking about livestock farming?
That's what Al Gore did in "An Inconvenient Truth" and this certainly is an important mistake. A newly-released Dutch movie aims to repair this lapse.

Yesterday morning was in London the World premiere of "Meat the Truth", a movie about livestock farming's contribution to climate change. The documentary is presented by Marianne Thieme, a Dutch MP of the "Party for the Animals".
Thieme's documentary mostly relies on a result of the study released by the FAO (UN Food and Agriculture Organisation) in 2006: "Livestock's long shadow".
This study showed that livestock farming accounted for 18% of the world greenhouse gas emissions, making it one of the worst contributors to global warming.
While cars and energy are often thought by the public to be the only big contributors to climate change, not many know the importance of agriculture and especially livestock farming's contributions to GHG emissions.

Although the 18% figure has recently been challenged, it is not really new to say that Western diets containing lots of meat are responsible for much more GHG emissions (especially methane, a GHG that is 25 times more powerful than CO2) than vegetarian diets. And there have already been several good posts on this topic on this blog (Simon's 1 and 2 and Will's).

But the movie manages to communicate effectively on this issue, with enough wit for the audience to feel challenged but not patronised.
One of the funny bits of the movie is Marianne meeting a former cattle farmer from Montana that became vegetarian after he realised how bad his industry was (a spine tumor was the thought-provoking event that made him change). Howard Lyman, nicknamed the "wild cowboy" appears as a convincing vegetarian (he is even vegan now).

At last, the end of the movie challenges the viewer to change his/her habits of eating meat. The less you eat meat (and dairy), the easier you can reduce GHG emissions from your food consumption (which DOES count a lot as I just said).
Mr Gore might have forgotten to talk about meat consumption's impact on climate change for the simple reason he "has been involved in the business of raising Black Angus for most of his life". Difficult to separate personal life and ideals sometimes...

So how far are you willing to reduce your meat consumption today?
