As E3G’s European Climate Diplomacy lead, Jennifer works on issues ranging from Transatlantic and Sino-European climate cooperation and competition; COP26; Climate risk and resilience diplomacy; and emerging European Green Deal Diplomacy.   

Jennifer works with policymakers, diplomats, foreign policy experts and civil society, to create the political space and build the diplomatic coalitions to accelerate international climate action. The Climate Diplomacy and Geopolitics teams works to build cooperation towards a climate safe world for all while managing the geopolitical competition in an emerging global clean economy that has the potential to drive a race to the top. She is also an expert on UN climate negotiations, having previously led E3G’s work on the UNFCCC.  

Before joining E3G, Jennifer worked on integrated climate risk management concepts at GIZ, looking at the climate risks facing small island developing states. Prior to that, she had worked on climate policy and resilience at the local level with ICLEI-Local Governments for Sustainability. 

Jennifer has a Master of Environmental Science, Policy and Management jointly awarded by the International Institute for Industrial Environmental Economics at Lund University (Sweden), the University of Manchester (UK) and Central European University (Budapest). She also studied Economics and Politics during her Bachelor (Hons) at the University of Cambridge.
