Bill Weihl is the Founder and Chief Strategic Advisor of ClimateVoice, a non-profit initiative launched in February 2020 that is mobilizing the workforce to encourage companies to go “all in” on climate - especially in their use of their voice and influence to support public policy, everywhere they operate.

From 2012 to 2018, Bill was Director of Sustainability at Facebook, leading work on sustainability across the company, and helping to launch the Renewable Energy Buyers Alliance (now CEBA). Prior to Facebook, Bill was Green Energy Czar at Google, where his team pioneered Google’s work to buy clean energy for its data centers and helped found the Climate Savers Computing Initiative with Intel and WWF.

Bill is on the board of directors of Acterra and Common Energy, and on the President’s Councils for Ceres and for Pathfinder International. He has received numerous awards, including Time Magazine's Hero of the Environment (2009), the Global Green Award for environmental leadership (2016), and the VERGE Vanguard Award (2018).
