Climate Transparency is an open global consortium with a shared mission to stimulate a ‘race to the top’ in climate action through enhanced transparency. For this purpose, comprehensive, comparable and credible information about government climate action is spread by bringing together the most important actors in assessing and communicating climate action for the benefit of key influencers and decision makers.

The Climate Transparency consortium produces the Brown to Green Report every year, providing a comprehensive overview of how the G20 countries are doing on the transition to a low-carbon economy. The report draws on the latest emissions data and covers over 80 indicators on decarbonisation, climate policies, finance, and vulnerability to the impacts of climate change. Providing country ratings, it identifies leaders and laggards of climate action in the G20. Additionally, a country profile is produced for each of the G20 countries. In 2019, Climate Transparency compiled 14 “Ambition Calls” which included concrete recommendations for more ambitious climate action in each of the 14 countries, in light of the Climate Ambition Summit on 23 September 2019 in New York.
