"When I had been the chief executive of BP for only a couple of years, I broke ranks with the rest of the industry. In 1997, I stood under a blazing Californian sun at Stanford University, and explained that BP: acknowledged the risk posed by climate change; accepted that it was a result of human activity; and wanted to do something about it. I was asked by other chief executives whether I had lost the plot. The American Petroleum Institute accused BP of ‘leaving the church’. And some NGOs accused us of ‘greenwash’, assuming that we were trying to distract attention from our core business." (Quoted from article)
