Forty-odd years ago, about to graduate from university, I received my first job offer, from BP. I accepted instantly. Oil was the industry of the moment. North Sea oil and gas was being developed, offering the UK a degree of freedom from the power of Opec and the risk of embargoes. The combination of economics and politics and the idea of working for a great company operating on a world stage was irresistible.

Now I’m often asked by students or their parents if they should consider a job in the sector. Would I make the same decision now?

Things have certainly changed. The oil and gas industry is under attack on many sides. Vilified by environmentalists for its contribution to the continuing growth in emissions and global warming, it faces an increasing number of court challenges from those seeking to prove the liability of individual companies for the damage done by climate change.
