Karoline Hallmeyer


Karoline Hallmeyer is an Analyst at Climate Policy Initiative, based in San Francisco, where she focuses on blended finance solutions and policy mechanisms to catalyze sustainable investment across mitigation and adaptation sectors. Her expertise lies in adaptation finance, climate risk, and mechanisms for market transformation. Working on CPI’s Global Innovation Lab for Climate Finance (the Lab) she helped to develop the Climate Resilience and Adaptation Finance and Technology Transfer Facility (CRAFT), the first private equity fund focusing the uptake of adaptation and resilience technologies and services in emerging markets and the Smallholder Forestry Vehicle (SFV), a fund that structures and re-finances portfolios of smallholder timber plantations in East Africa with the aim to support afforestation and farmers’ resilience. Karoline is also a lead analyst of the UK’s Climate Public Private Partnership Programme (CP3), which is a market mechanism that uses private equity to catalyze low carbon climate resilient investment in low- and middle-income countries. Since 2018, she has been a member of the Adaptation & Resilience Expert Group (AREG) organized by Climate Bonds Initiative (CBI) and advises on the development of principles to provide guidance for determining when projects and assets are compatible with a climate resilient economy.

Before she joined CPI, Karoline worked as research assistant for Professor Dr. Geoffrey Heal at Columbia University Business School. She holds a Bachelor’s degree in Political Science from London Metropolitan University and a Master’s degree in Climate & Society from Columbia University’s Earth Institute. She is a 2018 Fellow of the Clean Energy Leadership Institute.
