In this 3-minute clip from the film DIRTY BUSINESS, Rolling Stone reporter Jeff Goodell introduces Dr. Vaclav Smil, from the Environment program at the University of Manitoba. Smil has calculated that using "carbon capture and sequestration" (CCS) technology to curb coal’s greenhouse gas emissions would require an infrastructure twice as large as the entire existing petrochemical infrastructure. Julio Friedman argues that 1) we can do that, and 2) we must, if we’re going to avert the worst global warming. Others—Joseph Romm from the Center for American Progress, Rebecca Tarbotton from the Rainforest Action Network and Frank O’Donnell from Clean Air Watch—argue that burying CO2 emissions deep underground is going to be very tough to enforce internationally and will require something like UN weapons inspectors; that this technology will become an excuse to increase the mining and burning of coal, instead of weaning us off of coal, because CCS means you need to burn more coal to get the same amount of energy as you get from unfiltered coal plants.
