ExxonMobil agrees to join oil and gas climate change alliance

U-turn means company will join BP, Shell and Total in contributing $100m to project

ExxonMobil has joined the oil and gas industry's flagship climate change project, reversing its decision not to join the alliance four years ago.

The company was a notable holdout when the Oil and Gas Climate Initiative (OCGI) was launched, but will now join European peers BP, Shell and Total in contributing $100m (75m) to curb the impact of global warming.
