Shell cuts debt with $7.25 billion sale of Canada oil sands.

Shell on Thursday also amended its pay policy to better reflect incentives to control emissions. Cutting greenhouse gases, including both carbon dioxide and methane, from its refineries, chemical plants and burning of natural gas at its fields, will make up 10 percent of executives’ bonuses. This 10 percent weighting was split between energy intensity, controlling oil spills and water use last year, according to the company’s annual report.
