The Climate Transparency Report (previously known as "Brown to Green Report") is the world's most comprehensive annual review of G20 countries' climate action and their transition to a net-zero emissions economy.

The review is based on 100 indicators for adaptation, mitigation and finance and aims to make good practices and gaps transparent. The summary report and 20 country profiles allow the report to be a clear reference tool for decision makers.

This year's report consists of two parts: the annual policy assessment based on data of the previous year(s) is complemented by an analysis of the impacts of the COVID-19 crisis and recovery efforts on countries' climate ambition.

The Summary Report 2020 provides a comprehensive overview of all G20 countries, whether - and how well - they are doing on the journey to transition towards a net-zero emissions economy. The report draws on the latest emissions data from 2019 and 2020 and covers 100 indicators on decarbonisation, climate policies, finance and vulnerability to the impacts of climate change. Providing country ratings, it identifies leaders and laggards in the G20.
