here's the official pitch on COP-15:

THE GOVERNMENT'S GOALS FOR COP15

The government’s ambition is for the agreement to include as many countries as possible, and that the agreement must contribute to a reduction in man-made greenhouse gases which have a negative effect on our climate system.

The government will therefore put all its efforts into obtaining an agreement that combines respect for the environment, living standards and long-term security of energy supply in the best way possible.
