Why Tim Yeo is wrong about carbon emissions from UK aviation being controlled by the ETS

This piece from the Carbon Brief sets out how the carbon emissions from UK aviation are dealt with by the ETS, and why Tim Yeo (and others promoting huge expansion of UK air travel, beyond the limit recommended by the Committee on Climate Change), have got it wrong.  Besides the apparent misunderstanding about the failings of the ETS, Yeo also suggested that that if the UK were to increase its airport capacity, carriers would be more likely to send their newer, more efficient planes to Heathrow. Carbon Brief explains that this would not happen as there doesn’t seem to be any reason why airlines would send their newest planes to the UK over other EU destinations.  If the ETS works as it is meant to, the price of carbon permits would go up, so the cost of flying would go up.  And the UK would have to either cut down on aviation demand (very unlikely) or overstep its emissions cap, as no government would be popular if it tried to ration air travel. 


The Carbon Briefing:

Is Tim Yeo right to claim a third runway won’t make any difference to UK emissions?

  • 29 Aug 2012,  (The Carbon Brief)
  • by Ros Donald

Energy and Climate Change (ECC) Committee chair Tim Yeo has argued that a third runway at London airport Heathrow will not lead to extra greenhouse gas emissions due to the aviation sector’s inclusion in the EU Emissions Trading Scheme (ETS) this year. Could he be right?

Yeo was originally against the plan to increase Heathrow Airport’s capacity because he said a new runway would lead to an increase in greenhouse gas emissions. But now, he’s changed his mind.

As he wrote in a Telegraph column this weekend, he thinks the European Union’s decision to include aircraft emissions in the overall EU emissions cap in January means that as long as other industries continue to cut their emissions, the UK can afford to increase its aviation capacity. He writes:

“Even if we covered the whole of Surrey and Berkshire in new runways it wouldn’t actually lead to a single kilogram of extra greenhouse gas emissions taking place.”

Yeo also suggests that that if the UK were to increase its airport capacity, carriers would be more likely to send their newer, more efficient planes to Heathrow.

The UK’s Institute of Directors (IoD) agrees with Yeo. In a submission to the Department of Energy and Climate Change’s consultation on new airport capacity, it says:

“[I]nclusion of aviation in the ETS does allow aviation to grow without worrying about carbon emissions, given that emissions from air transport are now part of the overall cap. The logic of the ETS is to reduce emissions where it is most cost-effective to do so, which is unlikely to be in aviation. So the inclusion of aviation in the ETS should allow a long-term growth in air transport while the UK meets its emissions targets overall.”

Aviation in the ETS

Let’s look at how the ETS now applies to airlines. The UK’s Climate Change Act doesn’t currently cover the UK’s emissions from international aviation or shipping. This means that the ETS is the only mechanism aimed at limiting UK aviation emissions.

All aircraft operators became subject to the ETS in January this year.  This means that airlines receive emissions permits from the government of the EU member state they’re based in. On the 30th of March every year, they have to report their emissions, and from 2013 they’ll have to surrender enough allowances to cover them. They can emit more than their allowance by buying permits from the market or, if they emit less than the allowance, they can sell their leftover permits.

The ETS aims to reduce emissions from aviation in the EU every year by increasing the amount of emissions permits that must be bought. This year, the ETS cap on airline emissions is set at 97 per cent of average emissions from the sector in 2004 – 2006.

Eighty-five per cent of the emissions allowance is free of charge to airlines this year, leaving airlines to bid for the remaining 15 per cent of emissions at auction – a number that’s set to increase as time goes on. Airlines will be able to buy and sell allowances across the EU. They will be able to buy credits from other industries, but they’ll only be able to sell them to other airlines.

Will the ETS be enough to limit the UK’s emissions?

But not everyone agrees that the ETS will be enough to ensure extra Heathrow capacity doesn’t push up overall UK emissions. Commenters have pointed to high emissions caps, aloophole that allows carbon offset credits from outside the EU to be traded on the scheme and legal challenges against the inclusion of aviation in the ETS scheme from non-EU countries as reasons why the scheme isn’t enough on its own to keep emissions down if the UK keeps building runways. And that’s if the ETS manages to weather the current slump in emissions prices – critics have also pointed out that the scheme could fail altogether, as it already has – twice.

The Aviation Environment Federation (AEF) produced a response to Yeo’s claims in March, pointing out that cap and trade systems need complementary legislation to keep them stable. The federation claims that if the government decides to go ahead with the runway believing the ETS will iron out emissions problems, it could face a future crunch point if the price of emissions permits goes up. It says the UK would have to either cut down on aviation demand or overstep its emissions cap. AEF claims that the latter situation is much more likely, given that the government would make itself rather unpopular if it decided to limit aviation activity by closing runways or rationing air travel.

But this argument assumes that the ETS will function according to plan in the future, with emissions prices rising as the EU tightens the emissions cap next year as part of the scheme’s third phase. ETS expert Michael Grubb wrote a piece for the BBC after the second market crash in 2009, calling on the EU to step in to ensure the carbon price stops plummeting. Since he wrote the piece, of course, no such thing has happened. The carbon price crashed a third time this July, meaning it’s currently too low to drive emissions reductions – a low carbon price means it’s cheaper to emit greenhouse gases than invest in greener alternatives.

Improving the ETS

But could the ETS be strengthened to the point where we can be confident it will constrain aviation emissions? The EU released a plan in late July to bolster the market by delaying some carbon auctions, but this is unlikely to address the problem of oversupply.

The UK Parliament’s ECC Committee produced a report in January, which outlines a variety of mechanisms that could be used to raise the carbon price again. These include allowing countries to set aside emissions allowances aside, ensuring there aren’t as many available. Another possible solution could be to further tighten the emissions cap. But opposition from Poland appears to be holding these proposals back. The country has lobbied against set-asides and recently blocked a proposal for firm emissions milestones to be set in the lead-up to 2050 targets under the ETS.

The Committee on Climate Change – which advises the government on how to cut its emissions in line with the Climate Change Act – wants the government to add its own cap on aviation emissions in addition to the ETS. It says the government should formally include aviation in its carbon budgets, which are set every five years and place legally binding ceilings on the level of permitted UK emissions.

But what if emissions trading started to expand to include other countries? Australia and the EU announced today that they would start carbon trading from 2015, potentially laying the groundwork for a global scheme. The architects of the deal say that it will create greater certainty in carbon pricing. Critics have pointed out, however, that the EU is likely to dictate the level of pricing, which seems a bit risky given that the EU’s carbon price is looking so shaky at present.

Better planes

And then there’s Yeo’s claim that airlines will send their most efficient planes to the UK if it increases its capacity. This argument doesn’t seem to have much to do with the ETS. As the scheme also applies to other European countries, there doesn’t seem to be any reason why the cap would necessarily mean airlines would send their newest planes to the UK over other EU destinations.

But it doesn’t seem to be a serious argument in favour of the third Heathrow runway, either.Justine Greening, the current transport secretary, says the new runway won’t be a full-size one so it won’t be able to “take the new planes”.

So has the ETS fixed it?

Both Yeo and the IoD seem to think that the inclusion of aviation into the ETS has solved any question of whether increased capacity at Heathrow will have a negative effect on the UK’s carbon emissions. Unfortunately, this seems like a risky bet to make.

The ETS could start to work better, and the extra aviation capacity could become much more expensive, or the ETS may just give up the ghost again and leave aviation emissions unregulated. There may be other arguments in favour of a third runway, but claiming that the ETS has removed any cause for concern about emissions seems a bit weak.

Why Tim Yeo is wrong on aviation and the EU ETS

Date added: August 29, 2012

This is an article from BusinessGreen, with a good and clear explanation of why Tim Yeo is utterly wrong with his pronouncements on aviation and the ETS. You would have thought someone who is Chair of the Energy and Climate Change Select Committee should know this. The ETS cannot and will not prevent aviation emissions from rising, because of the current weakness and failures of the ETS, meaning it does not work properly, largely as the carbon price is too low and dubious credits are imported from outside. However, supposing the ETS did work perfectly, it would drive up the cost of flying hugely as permits become scarce and expensive as carbon cuts are harder and harder for other sectors to make. There would then be no need for more runways as demand would fall greatly. So no need for a new Heathrow runway, or a new airport. Unless planes could become virtually zero carbon – of which there is no current prospect.
