Assessing ambition of nationally determined contributions

23 Assessing ambition

A key for a successful new international climate agreement by December 2015 will be the collective assessment of ambition of individual proposals by countries on how and how much to reduce their greenhouse gas emissions. We here identify five methods for this assessment, namely comparison to: BAU, effort sharing approaches, mitigation potential, decarbonisation benchmarks, and best practice policy packages. We conclude that there is nothing right or wrong in choosing one or several of these approaches to assess the level of ambition of contributions. However, individual approaches lend themselves better to assess and show the level of ambition of certain elements of a contribution. An approach using several of many methods described can take into account the difference in national circumstances.
