A Los Angeles based ‘philanthro-activist’ group is claiming the world’s largest fossil fuel companies owe at least $209 billion a year in “reparations” for climate damages.

In a new paper entitled Time to Pay the Piper, One Earth argues climate change is a moral issue that will disproportionately impact developing nations in Africa, Asia and Latin America to the tune of $99 trillion from 2025-50, $70 trillion of which it attributes to fossil fuels.

“Human-caused climate change has long been acknowledged as essentially an ethical issue that threatens humanity and ravages the planet,” it said.
