Kaysie Brown appointed as Associate Director, Climate Diplomacy and Geopolitics


E3G is excited to welcome Kaysie Brown as Associate Director of Climate Diplomacy and Geopolitics in the U.S. office.

Kaysie Brown brings over twenty years of experience to E3G working at the cross-section of foreign policy, diplomatic engagement, and geopolitics in various roles as a policymaker, diplomat, and practitioner.

Kaysie previously served in the Biden-Harris Administration as Deputy Lead Negotiator on Pandemics and Senior Advisor in the Coordinator’s Office for COVID-19 Response and Health Security and was awarded the Department of State’s Meritorious Honor Award. She was also a member of the Biden-Harris transition review team of the U.S. Mission to the United Nations, served as Chief of Staff for the Sustainable Development Goals U.S. negotiating team, and advanced fragility and conflict response at the Bureau of Conflict and Stabilization Operations.

From 2015-2021, Kaysie was Vice President for Policy & Strategic Initiatives at the United Nations Foundation, where she led its policy work and advanced partnerships including the Business & Sustainable Development Commission, the World Benchmarking Alliance, the U.S. SDG Initiative, and the Local2030 Islands Initiative. She has overseen programs and projects at the Council on Foreign Relations, the Center for Global Development, the U.S. Global Leadership Coalition, and the International Peace Institute. She has written widely on issues related to global cooperation, sustainability, and geopolitics.

Reflecting on her new role, Kaysie Brown said:

“I’m honored to join E3G as their Associate Director on climate diplomacy and geopolitics. In this increasingly shifting and complicated global political environment, geopolitics not only shapes but is profoundly shaped by the impacts of climate change and the energy transition, presenting the single most critical challenge of our time. I am eager to leverage my experience in multilateral diplomacy, coalition building, and global cooperation to drive forward our collective efforts toward a more sustainable and resilient future.”

Clarence Edwards, Executive Director of E3G’s Washington DC office, said:

“We are thrilled to welcome Kaysie to E3G, and excited to have her working with us in Washington DC. Her range of experience in the U.S. government and in the broader global and multilateral policy community will benefit the organization as we work to understand this complex geopolitical era.”

Nick Mabey, Co-CEO of E3G said:

“We’re very pleased to welcome Kaysie Brown to E3G to lead our work on Climate Diplomacy and Geopolitics at this vital time – ahead of COP30 in Brazil next year, when countries’ commitments to the Paris Agreement will be tested, 10 years on from its signing. 

We are also very pleased that Kaysie joins us in E3G’s Washington DC office, where her insights into US politics and policy will provide so much value, not just for the team there, but for our whole organization”.
