Meet the companies responsible for producing the vast majority of our fossil fuels:

A recent paper by Richard Heede, from the Climate Accountability Institute, in Colorado, shows that just 90 companies produced two-thirds of the fossil fuels burned in the industrial era. That includes 50 investor-owned companies like Chevron and Exxon, 31 state-owned companies like Mexico’s Pemex, and nine government-run entities from the ex-Soviet Union, China and other countries.
