Climate Action Tracker

An independent science-based assessment tracking all countries‘ emission reduction pledges and their implementation. CAT assessments are regarded as the thermometer of international climate action ambition.

Independent Scientific Analysis

The Climate Action Tracker (CAT) is an independent scientific analysis that measures government climate action against the globally agreed aim of holding warming below 2°C of warming. It is produced by four research organisations: Climate Analytics, Ecofys, NewClimate Institute and Potsdam Institute for Climate Impact Research.
The Climate Action Tracker tracks the actions of 30 selected countries, all the biggest emitters and a representative sample of smaller emitters, focusing on:

  • Government climate action pledged to the UNFCCC (and INDCs, other commitments)
  • The policies a government has actually implemented to meet its commitments
  • Whether a government is doing its “fair share” compared with others
  • Comparison to emission reduction potential based on a literature review
  • Comparison of national and sectoral decarbonisation indicators

Individual country assessments, briefings and updates are available www.climateactiontracker.org

Latest

What can we say about the climate pledges that countries have submitted so far? The Climate Action Tracker, produced by four research orgsanisations in Europe, has rated most of the INDCs that have come in so far as 'medium'. This means that if all governments adopted this notion of how much they should do, warming would probably exceed 2°C.
