BP: we agree all reserves probably can't be burned.

BP annual report extract: “We agree that burning all known reserves would probably cause global temperatures to rise by more than 2°C – and that addressing this issue will require the efforts of governments, industry and individuals.” “However, we believe that the unburnable carbon approach to assessing the impact of potential climate regulation on a company’s value oversimplifies the complexity of the issue and overstates the potential financial impact”.”
