This report analyses pledge on emissions reductions put forward by Parties in the Cancún Agreements, including information emerging since the negotiations took place in 2010.

It focuses on the uncertainties and risks of achieving the goal of limiting the global temperature increase to 2 degrees Celsius, and provides a detailed overview what the pledges and actions of the 12 countries and regions with the largest emissions could mean for reduction targets.

The report highlights that since the Cancún negotiations, developing countries have published new information about their emission projections which have led to higher than expected emission levels, and have increased the emission gap.

It suggests that a selected set of mitigation options in addition to existing pledges could result in emission reduction which would narrow the gap towards achieving the two degrees Celsius goal. It also concludes that uncertainties in accounting rules and projections could mean that global emissions remain at business-as-usual projections for 2020.
