On average, public finance institutions controlled by G20 governments, along with
multilateral development banks such as the World Bank Group, provide $ 71.8 billion per year in public finance
for fossil fuels, and only $ 18.7 billion in public finance
for clean energy (figure taken from from the report
Talk is Cheap: How G20 Governments are Financing Climate Disaster, July 2017, available here).
Having said that, since the climate
talks have postponed a global treaty until it will be too late, radical unilateral action is needed to get a momentum
for multilateral agreement.
