David Wei

Managing Director

New York

As the lead of BSR’s climate team, David works with companies to develop and implement net zero climate goals, manage climate risks, integrate climate justice into company action, and incubate collaborations to build the net zero economy.

He strives to maximize the impact of our applied research, collaborative initiatives, and work with individual companies. This often means innovating how companies align with the Paris Agreement and implement the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD).

Before joining BSR, David was a climate diplomat for the Marshall Islands with the advisory group Independent Diplomat. In this role, he led on emissions reductions and transparency in the UN climate negotiations for the Alliance of Small Island States. As an international lawyer with the Foundation for International Environmental Law and Development, David built up the environmental treaty expertise of governments across the globe. He began his career as a securities litigator with Fried Frank in New York and as a commercial litigator with Cassels Brock in Toronto before focusing on climate change.

David holds a LLM in International Law from New York University, a JD and MA in International Relations from the University of Toronto, and a BA in Ethics, Politics, and Economics from Yale University.

He has two daughters likely to see warming at the end of the century firsthand, and he lives with them and his wife in New York City.
