Europe attempted to reassert its international leadership in the fight against global warming, offering to slash its greenhouse gas emissions by up to 95% by 2050 and by 30% by 2020 if a climate change pact is sealed in Copenhagen in December. "This should be seen as a clear message to the world," said Andreas Carlgren, the Swedish environment minister who chaired the Luxembourg meeting. "We expect to reach an agreement in Copenhagen," he added, after environment ministers from 27 countries finalised a common EU negotiating position. But his optimism contrasted with the increasing doubts around the world enough time remains to deliver a binding agreement in Copenhagen. The EU also still has to settle disputes over the EU's carbon trading scheme and how the developing world will be paid to cope with the impacts of global warming. European finance ministers failed to agree on a funding package for developing countries, with Poland and other poorer eastern European countries unhappy at being asked to subsidise action in countries such as China and India whose economies are growing strongly. Poland is also leading the dissent on the EU emissions trading scheme (ETS). The EU negotiating position offers to slash greenhouse gas emissions by between 80-95% by 2050 and to deepen cuts from 20 to 30% by 2020 if other world powers sign up for similar action. The ministers said they also reached accord on tough action on deforestation and agreed that aviation would have to cut its emissions by 10% by 2020 compared with 2005 levels and shipping by 20%.
