A mechanism to verify each state's compliance with its commitment to curb greenhouse gas emissions
Areas of disagreement:
The amount by which developed countries must cut their greenhouse gas emissions How much effort developing countries should make to curb their emissions Procedures for monitoring and verifying each country's emissions Whether countries should be legally bound to meet emission reduction targets The amount of money developed countries should transfer to developing countries, to help them curb emissions and adapt to the effect of climate change The mechanism for transferring this money, and how it should be raised The future of the Kyoto Protocol - whether it should be part of the Copenhagen deal, or replaced by it How many degrees of warming, above pre-industrial levels, should be regarded as the acceptable maximum
