The new president of the World Bank wants funds to invest in decrbonization of poor countries.

This lending program would be a good idea, but the highest priorities for investments in decarbonization are:

1. Getting wealthier countries to invest in their own decarbonization, They produce a lot more greenhouse gas than poor counries do. They do invest in renewable electric generation, but their fossil fuel extraction is still increasing year by year, and greenhouse emissions likewise.
2. Putting an end to funding for "aid" that takes the form of "investment" and "development" of fossil fuel extraction, transport and combustion in poor countries.

Shifting those funds to decarbonization aid would be the best way to start that.

But if we don't require these actions. decarbonization won't get off the ground.
