Governments have agreed to hold warming to below 2?C. The focus of emission reduction proposals to be submitted in INDCs during 2015 is for governments to put forward their proposed contributions to a “fair sharing” of effort to move global emissions downward in the period 2020-2025-2030.
The Climate Action Tracker rates INDCs, pledges and current policies against whether they are consistent with a countries fair share effort to holding warming to below 2°C.
“Effort Sharing” assessment methodology applies state-of-the art scientific literature on “to compare the fairness of government efforts and INDC proposals against the level and timing of emission reductions needed to hold warming to below 2°C. The main focus is on the period 2020, 2025 and 2030 (details here).
Inadequate: If all governments put forward inadequate positions warming likely to exceed 3-4°C.
Medium: Not consistent with limiting warming below 2°C as it would require many other countries comparably greater effort and much deeper reductions.
Sufficient: Fully consistent with below 2°C limit.
Role Model: More than consistent with below 2°C limit.
