He has been the president of En+ Group and United Company Rusal, the second largest aluminium company in the world,[4] until 2018.[5] After graduating from Moscow State University with a degree in physics, Deripaska became a metals broker specialized in trading aluminium before expanding into energy, machinery, financial services and agribusiness. In 2000, Deripaska founded Rusal, the result of a partnership between Sibirsky Aluminium and Roman Abramovich's Millhouse Capital.[6] In 2007, Rusal merged with SUAL Group and Glencore International AG to form UC Rusal, with Deripaska as chairman.[7] He was once Russia's richest man, worth $28 billion, but nearly lost everything due to mounting debts amid the 2007–08 financial crisis. As of May 2017, his wealth was estimated by Forbes at $5.2 billion.[8] Deripaska is also known for his close ties to Russian president Vladimir Putin, as well as his connection to American political consultant Paul Manafort, whom Deripaska employed from at least 2005 to 2009.[9] Deripaska is also the founder of Volnoe Delo, Russia's largest charitable foundation, and is reported to have donated more than $250 million to mostly educational causes.

The proposals were signed by more than 100 of the world's leading corporations and handed to the Prime Minister of Japan Yasuo Fukuda on 20 June 2008. The G8 leaders discussed the recommendations during the summit in Japan on 7–9 July 2008. The process was coordinated by the World Economic Forum in collaboration with the World Business Council for Sustainable Development.[120]
