The IEA last year said if the world wanted to meet climate targets, it would have to leave two thirds of its fossil fuels in the ground. So what does unburnable carbon mean for oil and gas giants?

Emissions controls will not be the only factor influencing our choice of future energy sources. The IEA and private analysts have pointed to the impending water crisis which could lead to stranded assets – particularly in coal and shale gas – and accelerate the push towards ‘dry’ technologies, like wind and solar PV.
