Facebook’s former sustainability director and Google’s former clean energy czar Bill Weihl has called on businesses to “go beyond their own four walls” and lobby for policies that create net-zero national economies in a “just” manner. Speaking at The Business Booster in Paris last month alongside Mary Robinson, former Irish President and incumbent chair of the UN Elders, Weihl was asked to give a brief summary of where he believed corporate leadership on climate justice currently sits, and what more must now be done to deliver a just transition to net-zero.
