The EU Emissions Trading System has failed to drive real action on carbon emissions. With the Copenhagen climate change conference approaching, what can be done to fix the system and improve carbon offsetting as an instrument to tackle climate change?
What is carbon offsetting?
Carbon offsetting is the process of attempting to redeem the CO2 generated by a particular activity, by paying a contribution to a project that will remove an equivalent amount of CO2 from the atmosphere, or prevent its release.
Got that? OK. Let’s try again.
“…carbon offsetting is Enron environmentalism, a neat accounting trick that does little to stop global warming. The government should focus on transforming the way we use energy here in the UK at the same time as helping to put the growing economies of the developing world on a low carbon pathway.”
Greenpeace statement on carbon offsetting, 17 January 2007
An offset is essentially a financial instrument, measured and traded in units corresponding to one tonne of CO2. Buy an offset, create a tonne of pollution (or visa versa). Your money funds projects to develop renewable energy, carbon sequestration (capturing and burying pollution), energy efficiency, or forestry. Theoretically, by the time you’re done, it’s as if you never polluted in the first place. In reality, assuming the project you contributed to was even fully successful, your carbon emissions may not be neutralised for years.
Proponents of offsetting see it as anything from a great way to create investment in renewable energy and energy efficiency to a panacea for developing countries. Another way of looking at carbon offsetting is that it is a license to pollute, what George Monbiot describes as “an excuse for business as usual”. When the ideal aim of reduction of CO2 emissions costs money and takes investment, effort and changes to infrastructure and behaviour, offsetting offers a great way out by paying for these things to happen elsewhere while you continue doing what you were doing all along.
Carbon offsetting is controversial, difficult to prove, and yet the most popular way so far to mitigate climate change.
How does offsetting work?

Cough up if you cough up.
Carbon offsetting activities can be split into two main types; the large scale offset trading of companies and governments to comply with greenhouse gas emissions capping within a regulatory regime set out by the Kyoto Protocol, and the smaller scale activities of organisations, companies, governments and individuals within a voluntary regime. That means anything from nation states building wind farms to a family paying for a few trees to be planted to offset their flight to Spain.
Since the introduction of the Kyoto Protocol on February 16 2005, 183 countries have agreed to put in place efforts to reduce 5 percent of their GHG emissions between 2008 and 2012 from 1990 levels, including Europe. The UK has since undertaken to reduce carbon emissions by 34% on 1990 levels by 2020, announcing the Low Carbon Transition Plan on 15 July.
Under the EU Emissions Trading System (ETS), also introduced in 2005, companies can buy and sell carbon credits representing one tonne of carbon emissions. In exchange for a payment, a company is allowed to emit carbon, with the payment contributing to the cost of projects that defray the environmental impact of those carbon emissions. If a company has excess permits, it can sell these in an open marketplace.
The failure of the ETS
The ETS has been compromised by political and commercial meddling since its inception. Emissions caps were initially set too high, ignoring the scientifically indicated effective level, and industrial lobbying has led to a market flooded with surplus permits.
After the introduction of the ETS, industry lobbied the EU over the perceived commercial threat posed by a strict carbon trading scheme – to tourism and transport, for example. To placate industry, emissions permits were over-issued, for free or from abroad in the form of Certified Emissions Reduction (CER) credits from the Clean Development Mechanism, a system where industrialised, high-carbon nations can buy credit from developing, low-carbon nations. This flooded the permits market, commoditising permits and driving down their value to less than €1 in the early stages. An ETS carbon credit costs about €14 at the time of writing, less than half of its peak value in 2008.
With low-cost, readily available emissions permits, combined with a reduction in emissions in the last decade due to recession and off-shoring, many European companies have acquired a massive surplus of emissions permits. For example, German company Integriertes Hüttenwerk has 10.3 million surplus permits, one in ten of all surplus permits in the EU. That’s roughly the amount of emissions one person creates by flying return from London to Sydney. Two and a half million times.
European industry is likely to have 400 million tonnes worth of surplus permits in the period 2008-2012, which could be sold for over €5 billion in profits, or simply banked for future use, potentially depressing permit prices for the foreseeable future, while having no effect on emissions levels. There is no formal mechanism for clawing these surplus credits back. Companies are effectively able to continue business as usual, profit from surplus credits, and further enable other companies to pollute. High limits on the use of CER credits and further stockpiling could lead to a possible surplus of 1.6 billion permits in the ETS, which may be kept in reserve up to 2020.
Failing the environment
The environmental concerns attached to the failure of the EU ETS are numerous.
- Firstly, with the reduced value of emissions permits and overall volatility of prices, no predictable revenue stream exists to undertake large-scale sustainable energy projects or other projects aimed at reducing the impact of emissions. A lack of investment in low-carbon technologies arguably renders the ETS redundant as one of its primary aims is to fund this investment.
- Secondly, the ability of companies to purchase CER credits through the Clean Development Mechanism allows industrialised nations to purchase credit from developing countries with lower emissions, enabling them to continue to pollute by claiming the credit of low-carbon nations. It goes without saying that the effects of climate change caused by continuing carbon emissions are often felt most severely in precisely those developing countries.
- Thirdly, European companies sitting on a potential surplus of 1.6 billion tonnes of emissions permits need take no action on cutting domestic emissions, keeping surplus permits banked for sale or offsetting.
- Finally, any benefit of lower emissions levels due to decreased fossil fuel consumption as a result of decreased industrial output is cancelled out by the sustained activity of polluting companies with surplus credits, as well as their having enabled other companies – particularly power companies – to pollute with traded credit.
The next steps
The United Nations climate change conference in Copenhagen this December presents an opportunity to address the failures of the current approach to climate change, stymied by the competing concerns of the economy and the environment – as the EU ETS so clearly illustrates.
Fixing the ETS
The EU ETS could still provide a template for fledgling international emissions capping schemes, even for a global emissions market.
UK campaigning organisation Sandbag is focussed on emissions trading, specifically fixing the problem of surplus low-price EU emissions permits. Sandbag provides supporters with the means to buy and ‘retire’ (tear up) emissions permits, thus taking permits out of the system which can not then be used to pollute. Companies like Carbon Retirement also focus exclusively on buying and retiring emissions permits.
Sandbag is also campaigning to tighten emissions caps, forcing industry and governments to take the action that the ETS was originally designed to promote – to develop low-carbon energy infrastructure. These measures, along with financial incentives for permit cancellation and setting reserve permit prices, could repair the bloated and ineffective ETS.
Gold Standard organisations such as Climate Care also provide brokerage, trading and offsetting services with a focus on investment in effective, high quality projects offering sustainable development.
Protest and awareness
Campaigning organisations continue to serve an essential function by raising public consciousness to the issues around climate change, and stimulating debate.
On the day of publication of the UK government’s Low Carbon Transition Plan, the World Development Movement described it as a ‘dangerous get-out-of-jail-free card’ due to the reliance of the plan on carbon offsetting. Furthermore the WDM has initiated the ‘Big If’ campaign to protest against the construction of the new E.ON coal fired power station at Kingsnorth in Kent, inviting supporters to vote for candidates who oppose the construction of coal fired power stations, organise vigils, and ‘stand in the way’. Actor Pete Postlethwaite, supporting the campaign, told the press at the launch of environmental documentary ‘The Age of Stupid’ that the government should be dissolved if it proceeded with the construction of new coal fired power stations. Projects like the new Kingsnorth facility can only go ahead with the use of carbon capture and storage (CCS) technology to sequester the huge amounts of carbon they will generate, and represent a step in the opposite direction from the development of renewable or low-carbon energy production.
Offsetting done right?

Surui land viewed with Google Earth
The Surui people of the Brazilian Amazon have been fighting a grassroots campaign with the assistance of environmental and monitoring groups, to protect their tribal lands from deforestation. They first drove settlers away in 1982 after their tribe was virtually wiped out by disease and loss of land in the wake of incursions by land speculators and loggers. The Surui have gained support from organisations who seek to promote the REDD (Reducing Emissions from Deforestation and Forest Degradation) approach to carbon capture, an approach based on the principle that forests are worth more intact than felled.
Though reforestation is a controversial approach to carbon offsetting (amongst other reasons, CO2 capture can be difficult to guarantee), the REDD approach suggests that leaving forests intact could go some way to mitigating up to one fifth of the world’s carbon emissions, and that intact forests, if closely monitored, are an essential component of a successful low-carbon future for the world. REDD attracts funding to communities in developing countries; the Surui map their lands with laptops and a high-resolution version of Google Earth, and they have been given funding for community education and health projects, and the establishment of sustainable industries. Industrialised countries can sink money into REDD projects as a component of their current cap-and-trade activities.
REDD may be our last, best hope of saving the tropical forests.
Rhett Butler, Washington Monthly
REDD has the potential to gain more support at Copenhagen as it is shown to be more vigorously monitored, offering quantifiable benefits and development opportunities for indigenous people, and able to offer other benefits such as the preservation of biodiversity.
The future
It is vital that EU leadership (in climate change) continues. We have to invest in the future and the future is low-carbon.
Nicholas Stern (author of the Stern Review on the Economics of Climate Change)
UN climate chief Yvo de Boer identifies four essential points that must be agreed at Copenhagen:
- How much are the industrialized countries willing to reduce their emissions of greenhouse gases?
- How much are major developing countries such as China and India willing to do to limit the growth of their emissions?
- How is the help needed by developing countries to engage in reducing their emissions and adapting to the impacts of climate change going to be financed?
- How is that money going to be managed?
Along with initiatives like REDD, clean energy development and low-carbon technology transfer to developing countries, fixing the EU ETS offers only part of the solution – and it’s worth noting that every question asked by de Boer above involves money. Idealistic ambitions to save the world will come to nothing if no one is willing to foot the bill.

Hi there,
I don’t think your criticisms are entirely fair. On the four in your conclusion:
1. EUAs have been volatile – just like oil and the economy. That’s a known feature of cap and trade – the demand for credits depends on economic factors. At times of lower anticipated industrial output, credits are cheaper. This can make it difficult for companies’ financial planning, but if they really want to they can buy financial products to fix the price, so the scheme feels like a tax (which it sounds like would suit you better).
2. CERs – I agree, admitting CERs into the scheme is not helpful. But some safety valve is necessary to get people to sign up.
3. This is not true – some companies/sectors have a surplus, but the scheme overall does not. If there was a surplus, the price of credits would be zero.
4. As #3 – the scheme must be making emission reductions or the credits would not have any value. The scheme cannot possibly increase emissions for anyone, so a reduction in some parts of the scheme = an overall reduction.
Best
Posted by Dan | 20. Aug, 2009, 7:48 amHi Dan, many thanks for your comments. Interesting to read. The conclusion you referred to isn’t the conclusion of the whole piece – sorry if that wasn’t clear. The rest is at the link ‘The next steps’, which refers to some of the ways to mitigate these issues.
To refer to your comments:
1) Yes, EUAs have been volatile, but with prices for EUAs dropping to less than €1 in phase 1 of the ETS, and having dropped again since last year, it’s a reasonable point to make. I referred to this article in the Independent describing some of these concerns.
2) Regarding CERs, were free EUAs not enough incentive?
3) I didn’t suggest that the scheme overall has a surplus, but if some companies have large surpluses which they can freely trade, this still comprises the efficacy of the system.
4) I didn’t say the sceme would necessarily result in increased emissions – but when companies with surpluses can pass permits to energy utilities, for example, this is surely doing nothing to improve the situation. Indeed, you have referred on your own blog to EU carbox dioxide emissions having exceeded permits by 25 percent – so would a net increase be really so inconceivable?
Posted by Nathan | 20. Aug, 2009, 10:10 am#2 – a more accurate way to think of allocation of EUAs is not that the member states have transferred valuable credits to the EU ETS installations, but a liability, which is the obligation to reduce their emissions. The credits are only valuable because the companies have to pay to comply with the EU ETS cap. The value of the EUA transactions within the scheme net to zero, of course, because participants ultimately sell to each other.
#3 – this is an issue for member states. They are trying to protect high intensity / trade exposed industries by giving them free credits. It is a financial issue for individual firms / sectors but does not affect the total quantity of emissions from the scheme.
#4 – it’s almost impossible for non-compliance to occur. The fines are so punitive that everyone complies. The 2008 data is for the first year of the phase so emissions are likely to exceed the cap. If anything the data suggests the cap is below the baseline emissions and the scheme has environmental value.
Thanks – I spotted your next steps page now. See what you think of our service ‘Carbon Retirement’ (and give us a plug if you like it
Posted by Dan | 20. Aug, 2009, 11:00 amThanks again for the comments Dan – I’ve added a link to the article.
Posted by Nathan | 20. Aug, 2009, 11:11 amGood post. The only thing I’d add would be the problems with ‘proving’ additionality with any offset. It will always involve judgements and that’s something that should be embraced. Offsetting standards will proliferate as we make progress, not converge on a single carbon price.
Posted by Declan | 20. Aug, 2009, 9:16 amThanks Declan – regarding proving offsets, this is where retiring credits and schemes like the CDM Gold Standard might come in – taking permits to pollute out of the system with quantifyable benefits and providing premium quality project-based offsets respectively. But you’re right, carbon offsetting is market-driven, so there may well be a whole raft of standards as things move forward.
