BP's outgoing chief, Bob Dudley, has said excluding natural gas from energy-transition efforts would be a "huge and unnecessary risk", even though both the public and politicians are seemingly turning against it. Oil majors such as BP and Shell have invested heavily in natural gas projects and are also now looking to champion technology such as carbon capture and storage, which could trap CO2 emissions below the ground. Natural gas emits about half the CO2 of coal and the oil companies claim its use would ease the transition to renewable energy sources.
