- Socioeconomics lead for the GCAM core model development team
- Lead modeler for the United States Mid-Century Strategy for Deep Decarbonization
- Expert in net-zero and negative emission strategies
Haewon McJeon is a fellow at the Center for Global Sustainability (CGS) and a research scientist at the Joint Global Change Research Institute, a partnership between the Pacific Northwest National Laboratory and the University of Maryland. His research focuses on developing methods for decision-making under uncertainties surrounding climate change. Dr. McJeon’s recent work has examined large-scale technology combinations and their impact on the cost of climate stabilization, the climate implications of globally abundant natural gas, and net-zero to net-negative emissions strategies for the century. He holds a Ph.D. in Environmental Policy from University of Maryland and a B.A. in Economics from Seoul National University.
- Integrated assessment modeling & scenarios; deep decarbonization
After the U.S. withdrew from the Paris Agreement in 2017, CGS led the analysis of commitments from the more than 4,000 cities, states, businesses, universities, communities of faith, and more who pledged to support the goals of the Paris Agreement in their own capacity. Since the U.S. officially rejoined the Paris Agreement in March 2021, CGS has continued working with U.S. subnational and international partners to deliver analysis that informs how an "all-of-society" ambitious and achievable U.S. climate strategy can drive actionable and feasible policy. CGS informs U.S. climate policy from the local to global through developing integrated modeling and climate scenarios for the federal government, advising on international discussions to ramp up ambition, and collaborating from the bottom-up to move the resources necessary to set and achieve ambitious climate goals.
