EU stumbles on the low-carbon road
By Stephen Mulvey
EU reporter, BBC News

Environmentalists have expressed grave concern that the European Commission could be about to drop plans to ensure that new cars produce a quarter less carbon dioxide by 2012.

The Commission had been expected this week to announce plans to force car makers to meet this tough target, despite warnings from the industry that it would push up prices and put jobs at risk.

The move would have been a concrete step towards the "post-industrial revolution" the Commission called for two weeks ago, to tackle climate change.

But sharp disagreements within the Commission have led to the postponement of the announcement, and environmentalists fear the plan will not survive in its original form.

Officials say Commission President Jose Manuel Barroso still favours ambitious legislation - but green lobbyists say they have privately heard the opposite.

Credibility

The EU has long been saying that cars should emit on average no more than 120g of CO2 per kilometre, though the deadline for reaching the target has been steadily slipping.

In 1999, car makers agreed to aim for 140g/km by 2008 - a 25% reduction from the 1995 level of 185g/km - but had reached only 162g/km by 2005.

Environment Commissioner Stavros Dimas's answer was to make 120g/km a mandatory target for 2012, but the idea has apparently run into opposition within the Commission.

"Failing to announce legislation ensuring that the 120g/km target is met would seriously undermine the credibility of the Commission," a group of 10 green non-governmental organisations wrote in an open letter to Mr Barroso on Tuesday.

"It would also mean that the Commission fails to deliver on its first real-world policy following the announcement on 10 January of a greenhouse gas reduction target of at least 20% by 2020."

Transport has the potential to knock off course Europe's efforts to reduce greenhouse gas emissions.

It generates more than one fifth of the overall emissions, and is the only sector where emissions have been dramatically rising in recent years - by 26% between 1990 and 2004.

Passenger cars alone account for more than one-tenth of the EU's CO2 emissions. Although the amount of CO2 they produce per kilometre has fallen since 1995, a rise in the number of cars being sold, and the distances driven, has more than compensated for this.

Better engines, better fuel

On Wednesday the European Commission was to have announced two measures, both of which have now been delayed.

The plan to impose mandatory restrictions on CO2 emissions from passenger cars would have obliged car makers to use technology to make cars more efficient, or to sell cars with smaller engines.

The other measure - a review of the fuel quality directive - would have obliged oil companies to produce fuels that released 10% less CO2 by 2020, taking into account emissions from all stages of the production and consumption process "from well to wheel".

This would provide an incentive for the rapid introduction of second generation biofuels, which are not yet available on an industrial scale.

To complete the package of proposals, the Commission was due to make a statement on existing plans for an "integrated approach" to reducing CO2 emissions from cars, covering things such as taxation, labelling, reducing congestion and changing drivers' behaviour.

Commission spokeswoman Pia Ahrenkilde Hansen said on Tuesday that one reason for the delay was the problem of ensuring coherence between all the various proposals.

The measures also have to be consistent with the papers mapping out the proposed low-carbon revolution published on 10 January.

Biofuel debate

One of these papers calls for biofuels to have a 10% share of the fuel market by 2020, but the proposed change to the fuel quality directive "results in completely different numbers", according to Peter Tjan, secretary general of the European Petroleum Industry Association.

Jos Dings of the Transport and Environment pressure group foresees a struggle between two different approaches to biofuels.

The 10% share can currently be achieved by production of any biofuels, including varieties whose manufacture entails sizeable CO2 emissions. This approach is favoured by the agricultural lobby.

By contrast, the amended fuel quality directive would put a premium on second-generation biofuels because these allow a big reduction in net CO2 emissions per unit of energy contained in the fuel.

Both the fuel and car industries warn of higher costs to the consumer if the Commission's plans go ahead.

Sigrid de Vries of the European Automobile Manufacturers Association (ACEA) says one study has estimated the cost of a small car could increase by between 2,500 and 4,000 euros if the 120g/km limit is enforced - though other studies are less pessimistic.

Other measures, such as reducing traffic congestion, would achieve the same reduction in emissions far more cheaply, she says.

March summit

But Jos Dings argues that all available mechanisms for reducing emissions from transport have to be grasped with both hands.

The 120g/km limit is absolutely key, he says, because it promises such a big reduction in emissions - 25% within a few years.

He points out that any increase in the cost of the car would be more than offset over its lifetime by savings on fuel, thanks to the engine's greater efficiency.

Stephan Singer, head of climate and energy policy for WWF in Brussels, also hopes that Mr Barroso will not waver, but is a little less gloomy than Jos Dings.

The key task for the Commission now, he points out, is to ensure that the next EU summit in March supports the big shift to a low-carbon economy, outlined on 10 January, with its headline goal of a minimum 20% reduction in greenhouse gas emissions by 2020.

If the prime ministers and presidents sign up to that, he says, tough action to rein in emissions from two sectors outside the EU's carbon emissions trading scheme - transport and construction - will become inevitable.
