Just 20 energy companies account for one-third of greenhouse emissions since 1965, according to a new study.
The Climate Accountability Institute’s Richard Heede tallied up all the fossil fuels extracted by every company through 2017 and calculated the emissions. The data is public, the math is straightforward and the emissions are indisputable.
The top 10 companies, in order, are, predictably, Saudi Aramco, Chevron, Gazprom, Exxon Mobil, National Iranian Oil Co., BP, Royal Dutch Shell, Coal India and PEMEX. More details are available online at http://climateaccountability.org/carbonmajors.html.
