@richardknott The purpose of these companies is to make a profit by extracting and selling oil. It's a bit utopian to think that they will stop doing it on their own.
It is a political problem, we can make the extraction of oil illegal, too expensive, by taxing each barrel extracted or the sale of oil not profitable enough, again with taxes.
These companies are just hoping to make as much money as possible before action is taken.
