Just 100 companies responsible for 71% of global emissions, study says

A relatively small number of fossil fuel producers and their investors could hold the key to tackling climate change

Just 100 companies have been the source of more than 70% of the world's greenhouse gas emissions since 1988, according to a new report.

The Carbon Majors Report (pdf) "pinpoints how a relatively small set of fossil fuel producers may hold the key to systemic change on carbon emissions," says Pedro Faria, technical director at environmental non-profit CDP, which published the report in collaboration with the Climate Accountability Institute.
