Ninety firms created most GHGs

Coal, gas and oil companies most responsible for greenhouse gases from 1854 to 2010

Ninety companies produced two-thirds of global greenhouse-gas (GHG) emissions from 1854 to 2010, new research indicates.

Chevron, Exxon Mobil and BP are among the corporations named in the study published in the journal Climatic Change, according to the Los Angeles Times. The list of offenders is largely populated by coal, gas and oil producers.

“These are the companies and institutions that have created the products … that have led to persistently higher levels of atmospheric carbon dioxide and methane,” said Richard Heede, head of the Climate Accountability Institute and author of the study.

Notably, a number of companies on the study’s list have funded the climate-change-denial movement. “For me, one of the most interesting things to think about was the overlap of large-scale producers and the funding of disinformation campaigns, and how that has delayed action,” said Naomi Oreskes, Harvard professor of the history of science, quoted in the UK’s Guardian newspaper.
