ALTHOUGH NOW CHAIRMAN of Masdar rather than CEO, Al Jaber still plays an important role in reducing the energy use of a country with among the world’s largest carbon footprints per citizen. He is at the forefront of Abu Dhabi’s renewable energy drive, and has also led Masdar’s to investments in clean energy projects across the world. He spearheaded the launch and establishment of Masdar in 2006, and also serves as the assistant minister of Foreign Affairs and the UAE’s Special Envoy for Energy and Climate Change.
