The United Nations Emissions Program (UNEP) has prepared a number of reports on the gap between the non-binding pledges that were made during COP 15 (the Copenhagen Agreement) and the maximum temperature rise of 2oC that was the objective of the pledges.

The UNEP Emissions Gap Report was prepared for COP 16 (Cancun) but the Appendices were released later.
