ExxonMobil and Chevron among worst in terms of CO₂ emissions and investment in renewables, according to research

Oil and gas companies in North America are lagging behind their European counterparts in cleaning up their operations, new research has found, with higher greenhouse gas emissions and less investment in clean alternatives.

ExxonMobil and Chevron of the US, alongside Canada's Suncor, ranked lowest in a review conducted by the Carbon Disclosure Project (CDP) of 11 of the world's biggest oil and gas companies. At the top of the table came Statoil of Norway, Italy's Eni and the French company Total.
