The Geneva-based firm set up a renewables and power division in 2019 to be a third core pillar alongside metals and oil trading. It also formed a joint venture called Nala Renewables to invest in green energy. Hauman was most recently head of crude oil for Europe, the company said in a statement said. The new carbon team will be based in Geneva, Houston and Singapore.
