The G20 Transition towards a Net-zero Emissions Economy
The Brown to Green Report is the world’s most comprehensive annual review of G20 climate action: it provides concise and comparable information on mitigation, finance and vulnerability. The report is published annually by „Climate Transparency“, a global partnership of 14 climate research organisations and NGOs from the majority of G20 countries, many from emerging economies. Germanwatch is one of the main authors.
The G20 make up two thirds of the world population, produce four fifth of the global economic output, and account for three quarters of global Greenhouse gas emissions. The average G20 per capita emissions are nearly 11 tons of CO2e. To keep global warming below 2°C, global per capita emissions need to be reduced to 1-3 tCO2e by 2050. The study "20 Climate Action – a turning point?" gives an overview on the current situation of the G20, as well as looking for trends and future plans.
