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 country's fair share effort to holding warming to below 2°C.
The CAT “Effort Sharing” assessment methodology applies state-of-the art scientific literature on how 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.
In 2017, the CAT rating system will be updated to reflect the Paris Agreement’s stronger 1.5°C limit.
|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 to make a 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.|
