Oil companies are collaborating on developing cleaner energy ahead of the Paris climate summit in December.
The companies are hoping to improve their individual efforts by joining forces on R&D into cleaner power, particularly into developing carbon capture and storage, the Financial Times reports.
Patrick Pouyanne, chief executive of French energy company Total, said at the Oil and Money conference:
We have all had some experience individually, but it's one area where we could join forces. There are other topics that we are discussing between us so you will see more concrete proposals.
Several oil giants are also seeking to cooperate with the United Nations, and with individual governments to help devise plans to combat global warming. Firms include Shell and BP, which recently sought to talk to governments about creating a global carbon pricing system.
