Shell has set net zero targets, such as cuts emissions from its business towards net zero by 2050. The big question is what does so-on do with these billions of dollars of profits? Does he keep returning it to shareholders? Or does he suddenly decide to divert a much larger chunk of that cash towards the newer parts of the business and to set Shell on an even faster path towards net zero? What are the biggest challenges someone is going to face? Is there any skill set he needs to brush up on before he can really do this job well?
