"Shell, I believe, was one of the first to come out and say, 'First of all, we recognize climate change.  The next thing is we accept the fact the majority cause is manmade, a large part of it going to fossil fuels.  There has to be a solution,'" said Angus Gillespie, Vice President for CO2, Shell Oil Company.  Gillespie discusses Shell Oil's work to combat climate change, including an internal price on carbon and being very vocal about climate as an issue.
