Nicke Widyawati

Revenue at Indonesia’s state-owned oil and gas giant climbed 39% to $57.5 billion last year, and profits soared 95%. Widyawati, in her fourth year as CEO, is now navigating a swirl of geopolitical issues made more complex by Pertamina’s status as Asia’s largest gasoline importer. Fresh off a corporate reorg, the company is pushing further into greener energy—14% of its investment goes to renewables; Widyawati is chairing the G20’s business task force on energy.
