Shell Chief Executive Peter Voser said Wednesday that he wanted to work on the sustainability agenda when he retires from the oil major next year.
"I want to give something back which I learned over the last 30 years and work on the sustainability agenda long term, which body, which area, I have no clue at this stage," he told reporters.
Mr Voser, who last month said he would retire next year, said he planned to take up some non-executive directorships on boards, though not on the board of Shell.
Mr Voser will be retiring at the age of 55 and will have served five years as chief executive. He joined the company in 1982, left for an executive position with ABB Ltd 20 years later and then returned to Shell in 2004 as chief financial officer.
