Britain said on Saturday it was still looking into the possibility of introducing a car scrappage scheme to boost the recession-hit vehicle industry, despite a report that the Treasury was blocking the idea.

Under the proposed scheme, cars more than nine years old could be scrapped in return for a 2,000 pound ($2,946) discount on a new car.

The amount of litter dumped on beaches across Britain has more than doubled in the last 15 years to its highest ever level, endangering the health of wildlife and humans, according to a survey on Wednesday.

The Marine Conservation Society (MCS) said its beachwatch 2008 annual survey had found an average of 2,195 items of litter per kilometer of beach, a rise of 110 percent since 1994.

Britain's Prime Minister Gordon Brown said on Wednesday the upcoming budget will contain environmental measures to aid recovery from recession, including creating thousands of "green" jobs.

The government launched a campaign on Tuesday to get the public to reuse carrier bags, saying each shopper got through 13,000 bags in a lifetime.

The leaders reaffirmed a previous commitment to sign a U.N. climate deal this year, a step the U.N. climate-change chief said was useful, though action would be better.

The European Union's Emissions Trading Scheme was at least 40 million tons short of carbon permits in 2008, analysts said after reviewing preliminary EU data on Wednesday.

Carbon market analysts said discounting incomplete data and comparing like-for-like figures between 2007 and 2008 showed companies emitted between 40 and 100 million tons over their allocated quota of emissions permits.
