The "Climate Action Tracker" is an independent science-based assessment, which tracks the emission commitments and actions of countries. The website provides an up-to-date assessment of individual national pledges, targets and INDCs and currently implemented policy to reduce their greenhouse gas emissions.
The CAT tracks 32 countries covering around 80% of global emissions. All the biggest emitters and a representative sample of smaller emitters covering about 80% of global emissions and approximately 70% of global population. The national actions we track are:
- Effect of current policies on emissions: The policies a government has implemented or enacted and how these are likely to affect national emission over the time period to 2030, and where possible beyond.
- Impact of pledges, targets and INDCs (link) on national emissions over the time period to 2030, and where possible beyond.
- Fair share and comparability of effort: Whether a government is doing its “fair share” compared with others towards the global effort to limit warming below 2?C.
CAT calculates global warming consequence and emissions gaps. The Climate Action Tracker assesses the total global effort of INDCs, pledges and current policies.
Rating countries
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.
