The world's biggest companies have caused $28 trillion in climate damage, a new study estimates

A new study estimates that the world’s biggest corporations have caused $28 trillion in climate damage, which is a shade less than the sum of all goods and services produced in the United States last year. A Dartmouth College research team came up with the estimated pollution caused by 111 companies, with more than half of the total dollar figure coming from 10 fossil fuel providers: Saudi Aramco, Gazprom, Chevron, ExxonMobil, BP, Shell, National Iranian Oil Co., Pemex, Coal India and the British Coal Corporation. The study is part of an effort to make it easier for people and governments to hold major polluters financially accountable, like the tobacco giants were. The study was published in Wednesday's edition of Nature.
