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.

Thermometer shows the global-mean temperature increase above pre-industrial by 2100, with an uncertainty range originating from carbon-cycle and climate modelling.

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 well below 2°C, and pursuing efforts to limit warming to 1.5°C. It is produced by two research organisations: Climate Analytics, and NewClimate Institute.

The Climate Action Tracker tracks climate pledges and policies of 32 countries, covering around 80% of global emissions, including all the biggest emitters and a representative sample of smaller emitters. The analysis focuses 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

This policy brief discusses economy-wide and sector-level benchmarks in 2030 and beyond for Japan to be consistent with the Paris Agreement’s long-term 1.5°C warming limit, based on recent analyses by the Climate Action Tracker and its member organisations, NewClimate Institute and Climate Analytics. The benchmarks presented in this brief are set in such a way that the world would not have to rely excessively on unproven negative emission technologies in the second half of this century.  
The recent wave of net zero targets has put the Paris Agreement’s 1.5°C within striking distance. In this global update, the Climate Action Tracker (CAT) has calculated that global warming by 2100 could be as low as 2.1°C as a result of all the net zero pledges announced as of November 2020.  
This report, the fifth country assessment in the Climate Action Tracker's Scaling Up Climate Action Series, analyses three key areas where Turkey could accelerate its climate action: electricity supply, road and rail passenger transport and the residential buildings sector. The report illustrates GHG emissions reductions from such actions, along with other benefits for sustainable development.  
Australia is lacking the national political commitment to stimulate the economy-wide transformational changes required for increased climate mitigation ambition. High level government climate leadership is not only absent, but the government is even directly undermining adequate climate mitigation, according to this report by Climate Analytics and New Climate Institute, part of the Climate Action Tracker’s Governance Series.  
There is room for improvement in the Philippines’ political commitment to climate mitigation. The Philippines has played a leadership role on climate change internationally, including in securing the 1.5°C temperature limit in the Paris Agreement. However, it could bolster this position by undertaking and showcasing domestic mitigation efforts, according to this report by Climate Analytics and New Climate Institute, part of the Climate Action Tracker’s Governance Series.
