ChevronTexaco was the leading emitter among investor-owned companies, causing 3.5% of greenhouse gas emissions to date, with Exxon not far behind at 3.2%. In third place, BP caused 2.5% of global emissions to date. (Guardian). Narrow it down to the real power-brokers and decision-makers—the CEO's of fossil fuel companies or the energy ministers from the largest petro-states—says climate researcher Richard Heede, and the actual individuals most responsible for the political world's continued refusal to address the planetary crisis of climate change "could all fit on a Greyhound bus or two."
In a newly compeleted study by Heede and his colleagues at the Climate Accountability Institute, their analysis shows that a mere 90 companies, some private and some state-owned, account for a full two-thirds of all greenhouse gas emissions that are now driving perilous rates of global warming.
