A primary goal of the Durban Platform negotiations should be to develop an agreement that will maximize reductions in greenhouse gas emissions over time. Achieving this objective will be a function of not only the ambition of the 2015 agreement, but also the levels of participation and compliance by states.

For a decade and a half, the principal aim under the U.N. Framework Convention on Climate Change (UNFCCC) had been to establish, and then to extend, a legally-binding regime regulating greenhouse gas (GHG) emissions.
