He strives to maximize the impact of our applied research, collaborative initiatives, and work with individual companies. This often means innovating how companies credibly align with the Paris Agreement, adapt to inbound climate disclosure regulation, and take advantage of growing interest in science-based nature goals. David also directs BSR’s Transform to Net Zero collaborative initiative. 

Before joining BSR, David was a climate diplomat for the Marshall Islands with the advisory group Independent Diplomat and 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 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.
