Science reports: Last month, geographer Richard Heede received a subpoena from Representative Lamar Smith (R-TX), chairman of the House of Representatives Committee on Science, Space, and Technology. Smith, a climate change doubter, became concerned when the attorneys general of several states launched investigations into whether ExxonMobil had committed fraud by sowing doubts about climate change even as its own scientists knew it was taking place. The congressman suspected a conspiracy between the attorneys general and environmental advocates, and he wanted to see all the communications among them. Predictably, his targets included advocacy organizations such as Greenpeace, 350.org, and the Union of Concerned Scientists. They also included Heede, who works on his own aboard a rented houseboat on San Francisco Bay in California.
Heede is less well known than his fellow recipients, but his work is no less threatening to the fossil fuel industry. Heede (pronounced “Heedie”) has compiled a massive database quantifying who has been responsible for taking carbon out of the ground and putting it into the atmosphere. Working alone, with uncertain funding, he spent years piecing together the annual production of every major fossil fuel company since the Industrial Revolution and converting it to carbon emissions.
Heede’s research shows that nearly two-thirds of anthropogenic carbon emissions originated in just 90 companies and government-run industries. Among them, the top eight companies — ranked according to annual and cumulative emissions below — account for 20 percent of world carbon emissions from fossil fuels and cement production since the Industrial Revolution.
