New Delhi: European Union (EU) hit out at the United States saying that others have to foot the bill for the latter's refusal to ratify the Kyoto Protocol on reducing emission of greenhouse gases.

EU also said that it is looking at new alliances beyond the developed and developing world framework to accelerate the use of renewable energy resources in the world.

"EU is already looking beyond 2012 and has reduced its emission by 3.5 per cent upto 2000 from the 1990 levels. The US has left the family and we are trying to convince them that this is the best and only show in town," EU's head of division, climate change, Thomas Becker, at the UN conference on climate change.

Speaking to reporters, Becker said that the EU is also putting in place the emission trading mechanism (ETM) to make the greenhouse reduction mechanism cost effective.

However, he said that the middle income group among the developing countries should also "start looking at their obligations towards cleaner environment, if not in terms of targets of emission reduction than at least greater use of renewable energy".
