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

Governments are wrapping up a meeting in Bonn, Germany, to figure out how to implement a global climate agreement. The conference has focused on the pledges to reduce greenhouse gas emissions, which nations made two years ago in Paris. But even as negotiators debate the details, scientists are warning that carbon dioxide levels are again on the rise, and the efforts in Paris may not be enough.  
BONN, Germany (Reuters) - Global warming is likely to be slightly less severe than previously expected thanks to stronger climate policies by China and India that will offset less U.S. action under President Donald Trump, a study showed on Wednesday.  
The outlook for curbing global warming has improved since last year as a result of policy moves in China and India, analysts said on Wednesday. In a report released on the sidelines of UN climate talks in Bonn, Climate Action Tracker (CAT) lowered their temperature rise prediction this century from 3.6C to 3.4C.  
The New Zealand government’s newly announced climate policies – with the goal of making New Zealand’s electricity system fossil fuel free by 2025 and reducing emissions to net zero by 2050 – have drawn international praise but the Climate Action Tracker reveals the NZ ambition is not ‘fine’ as claimed.

This briefing is the annual Climate Action Tracker estimate of global progress towards the Paris Agreement goals, with some positive and negative findings. While there is a significant improvement on climate action globally, despite US rollbacks, President Trump’s announced intention to withdraw from the Paris Agreement, has led to a significant deterioration in the effect of Paris Agreement commitments (NDCs)—by about 0.3°C.
