The Climate Transparency Report 2020

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.

“The consequences of climate change can already be felt. We need to prepare and take decisive action now. The Climate Transparency Report names adaptation measures that are needed and what countries should include in their plans.”

Christiana Figueres, Founding Partner, Global Optimism and former Executive Secretary, UNFCCC


“The post-corona recovery packages can lead to a greener and more just world. Unfortunately, many do not live up to that aspiration. The Climate Transparency Report provides an excellent overview of the recovery programs with good examples as well as missed chances.”

Prof. Joseph Stiglitz, Nobel laureate economist, Columbia University


“We are at a crossroads: one road leads to climate crisis with extreme heat, fires and flooding increasingly impacting G20 countries, the other to a resilient, sustainable and inclusive future for all. G20 leaders need to reaffirm their commitment to the right course. The Climate Transparency Report identifies clear opportunities for the G20 to enhance climate ambition on the road to COP26 and to align their financial systems with the Paris goals and the SDGs.”

Laurence Tubiana, CEO European Climate Foundation


“Climate crisis is already here and countries need to do much more to fight it. The future is now or there is no future. The Climate Transparency Report clearly shows what each country should do, so if you still do not know, which actions are necessary, you must read it, there is no excuses!”

Nicole Becker, Jovenes por el Clima, Argentina


“The G20 represents some of the highest emitting countries in the world. They therefore have a responsibility to lead with ambitious climate action. The Climate Transparency Report not only helps these countries understand how much more they need to do, but also helps citizens in holding these governments accountable for implementing the Paris Agreement.”

Tasneem Essop, Executive Director of Climate Action Network-International

Climate Transparency launched its “Climate Transparency Report 2020” on 18 November 2020.
