In this report, we aim to better understand the implications of different effort-sharing criteria and metrics on emission reduction efforts for key countries in the post-2015 agreement.

The report, produced for the German environmental protection agency Umweltbundesamt (UBA), evaluates available options for a variety of aspects around the differentiation of mitigation commitments.

This paper explores a wide range of air-pollutant emissions over the twenty-first century consistent with the global CO₂ paths of the RCPs.

The emissions gap in 2020 is the difference between emission levels in 2020 consistent with meeting climate targets, and levels expected in that year if country pledges and commitments are met. As it becomes less and less likely that the emissions gap will be closed by 2020, the world will have to rely on more difficult, costlier and riskier means after 2020 of keeping global average temperature increase below 2°C.
