The US is in Copenhagen with a very strong hand, having succeeded in significantly furthering its basic agenda of refusing to commit itself to a substantial reduction in emissions until the major developing economies are on board. It is also clear that the US remains firmly committed to ensuring that its hegemonic interests are not seriously compromised by the outcome of climate change negotiations. With the climate laggards in tow, and a pliant European Union unwilling to assert its better instincts, there is a serious danger that the US would dominate the endgame at Copenhagen with an outcome that substantially meets its requirements, at the cost of the developing countries. Above all, a US-led outcome would spell an end, at least temporarily, to serious emissions cuts by the developed countries.
