Some of the world's richest billionaires each emit about 3 million metric tons of carbon dioxide on average per year, more than 1 million times the amount emitted by 90% of people, according to a new study.
The sample consisted of 125 billionaire with investments in 183 corporations, and who have a combined corporate equity value of $2.4 trillion. About 50 to 70% of their emissions stem from their investments.
Collectively, their annual carbon dioxide emissions total about 393 million metric tons, which is about the same annual carbon footprint of France with its population of 67 million people, according to the report by Oxfam, a charity collective that aims to reduce poverty.
