Climate Action Tracker

Tracking progress toward the globally agreed aim of holding warming well below 2°C


Under the Paris Agreement, countries submitted emissions reduction commitments as (Intended) Nationally Determined Contributions. A crucial question is whether the individual national reduction commitments will be sufficient to ensure that global emissions remain below the 2°C and 1.5°C limits specified in the Paris Agreement.


Guidehouse, Climate Analytics, and New Climate Institute jointly run the Climate Action Tracker (CAT). The CAT is an independent science-based assessment that tracks the emission reduction commitments and actions of countries. The website provides an up-to-date assessment of individual national pledges to reduce greenhouse gas emissions.

CAT quantifies and evaluates climate change mitigation commitments and assesses whether countries are on track to meet them. It then aggregates country actions to the global level, determining the likely temperature increase by the end of the century. CAT also develops sectoral analysis to illustrate required pathways for meeting the global temperature goals.


Supporting the international climate negotiations with insights, the CAT has provided an up-to-date assessment of official emission reduction pledges of countries, an evaluation of their stringency, as well as an overview of the aggregate effects on global emissions since 2009.

CAT aims to make emission reduction pledges transparent and to encourage countries to increase their level of ambition. The project is funded by the ClimateWorks Foundation and the German Ministry for Environment, Nature Conservation and Nuclear Safety (BMU) via the International Climate Initiative.
