Billionaire Michael Bloomberg announced Wednesday that he will donate $64 million to environmental organizations after the US government moved to roll back Obama-era measures to counter climate change.

Repealing the Clean Power Plan (CPP) was a campaign promise by President Donald Trump and follows his decision in June to withdraw from the 2015 Paris agreement to cap global warming.

Bloomberg, the former mayor of New York, termed the repeal effort "a mistake," but said that progress is already being made on limiting pollution from power plants and that "we will continue doing it even without leadership from Washington."

Among the recipients of the Bloomberg donation is the Sierra Club's Beyond Coal campaign, which pushes for the closure of old coal power plants and works to prevent new ones from being constructed.
