The 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 independent, in-depth assessment draws on the latest analysis of international renowned data sets such as the OECD, World Bank, and IEA, as well as qualitative data from leading global experts in the field.

The review is based on 80 indicators for adaptation, mitigation and finance compared against 1.5°C global benchmarks and aims to make good practices and gaps transparent. The summary report and 20 country profiles allows the report to be a clear reference tool for decision makers.

This year’s policy assessment is more detailed than previous ones. The report features a novel analysis of climate impacts in G20 countries, their adaptation plans and their policies for greening the financial system.
