90 Companies Account for Two-Thirds of Global Emissions: a New Look at who is Responsible

A widely-cited article in the November issue of Climatic Change analyzed the greenhouse gas emissions produced by the largest investor-owned and state-owned companies, rather than the usual metric of national emissions.  The results show that nearly two-thirds of carbon dioxide and methane emissions from 1854 to 2010 can be attributed to 90 companies, with almost 30% of emissions produced by the top 20 companies .  Among state-owned companies,  Russian enterprises produced 8.9% of the total emissions, with China accounting for 8.6% of total global emissions. Among investor-owned companies, ChevronTexaco was the leading emitter, causing 3.5% of global emissions, with Exxon causing 3.2% and BP causing 2.5%. The data in the article was constructed using public records and data for the period 1854 to 2010, from the U.S. Department of Energy’s Carbon Dioxide Information and Analysis Centre. Author Richard Heede states, “the present analysis…invites consideration of the suggestion that some degree of responsibility for both cause and remedy for climate change rests with those entities that have extracted, refined, and marketed the preponderance of the historic carbon fuels.” Read “Tracing anthropogenic carbon dioxide and methane emissions to fossil fuel and cement producers, 1854-2010”  in Climatic Change (November 2013) at: http://link.springer.com/article/10.1007/s10584-013-0986-y
