Climate Transparency

The project combines the most critical climate assessments and the expertise of various institutions from G20 countries. Working together, experts use independent, comparable and comprehensive data to show how far the transformation from a fossil to a green economy has progressed in the individual G20 countries. The annual “Brown to Green Report” contains clear information on emission reduction, vulnerability and finances. By using this information for the climate performance of the G20 countries, the project strengthens the knowledge of key stakeholders in Argentina, Brazil, India, Indonesia, Mexico and South Africa, expanding their capacity to initiate ambitious climate protection measures. Workshops, briefings, publications and media reports inform government representatives, G20 stakeholders, NGOs (Non-Governmental Organisations) think tanks and companies about the climate-friendly transformation from fossil fuels to renewable energies (“brown to green”).

State of implementation/results

  • The Climate Transparency Report (CTR) 2021 was published on 14 October 2021, followed by national launch events in Argentina, Brazil, Indonesia, South Africa, Mexico, and South Korea. The CTR continues to push for more ambition in G20 climate action. Partner organisations in the countries have identified key opportunities in individual countries that should be pushed to maximise ambition in climate action. The CTR is published annually and produced jointly with Climate Analytics and other project partners.
  • This year's CTR includes the NDC Transparency Check with assessments of all G20 countries that have submitted expanded or updated NDCs. All assessments are published on the CT website.
  • The project has produced several papers, including one on decarbonisation of the transport sector in India, and one on energy transition in Mexico.
