BRUSSELS, Dec. 5  -- The European Union has agreed to have 10 percent of its vehicle fuels sourced with renewable fuels by 2020 in spite of warnings from scientists.

Scientists have said that turning forests or grasslands into farmland to make up for acreage lost to biofuel production undermines the claim that biofuels is a clean source of energy, Deutsche Welle reported Friday.

But an agreement between the European Parliament, the European Commission and European Union member states, upholds the 10 percent target proposed in January, as the three parties agreed to count non-food source biofuels twice.

Klaus' aide told reporters after the meeting that the president "considers Cohn-Bendit's behaviour a big provocation."

Cohn-Bendit said that Klaus was infuriated by his question on his relationship to Irish businessman and anti-EU activist Declan Ganley, who successfully rallied opposition to the Lisbon Treaty in Ireland, aktualne. cz news web site reported.

MOSCOW, Dec. 4  -- The European Union should stop "clinging to the past" in its attitudes towards Russia, Prime Minister Vladimir Putin said Wednesday.

He welcomed the EU decision this week to resume discussions on a new treaty with Russia. The talks had been suspended after Russian troops entered Georgia in August.
