What is CAT?

What is the Climate Action Tracker?

The Climate Action Tracker (CAT) is an independent scientific analysis produced by three research organisations tracking climate action and global efforts towards the globally agreed aim of holding warming below 2°C, since 2009. 

The CAT Consortium

Climate Analytics


NewClimate Institute

PIK (Potsdam Institute for Climate Impact Research) is a collaborator of the project as scientific advisor and data provider. The global aggregation and pathway extension methodology and tools were developed by PIK as partner in the project between 2009 and 2016. The consortium has now absorbed activities previously performed by PIK. The global aggregation and climate modelling methods from PIK are still used for the CAT temperature calculations and emissions data from the PIK PRIMAP emissions module are used for the country analysis.

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:

CAT calculates global warming consequence and emissions gaps

The Climate Action Tracker assesses the total global effort of INDCs, pledges and current policies on:

New Developments in course of 2015/2016

Past consortium members have included the Potsdam Institute for Climate Impact Research (2009–2016).

The Climate Action Tracker is made possible due to generous support from the ClimateWorks Foundation and the German Ministry for  Environment, Nature Conservation, Buildings and Nuclear Safety (BMUB) via the International Climate Initiative. Past supporters include the European Climate Foundation and the Children’s Investment Fund Foundation.
