Shell’s executive vice president for renewables and energy solutions, Elisabeth Brinton, is quitting the post, she announced on Tuesday, prompting a shake-up that will see Thomas Brostrom take the leading role in the oil supermajor’s growing green power generation operation.

Brinton, who took the role two years ago, said in a Linkedin post: “I’ve been offered a unique opportunity that I couldn’t pass up. I am not going to a competitor but will continue to be a global leader advancing sustainability and commercial net-zero energy transition strategies.”
