Chelsea worked as a Staff Scientist based at SEI’s Seattle office until January 2013; she focused on climate change mitigation issues.

She worked on developing tools to quantify greenhouse gas (GHG) emissions reduction strategies and policies from global to city scales, conducting long-term scenario modeling, and analyzing offset methodologies.

Projects included development and delivery of materials for United Nations Framework Convention on Climate Change (UNFCCC) regional training workshops on mitigation assessment; revision of the Global Environment Facility’s methodology for calculating GHG emissions reductions from energy efficiency projects; a GHG inventory and tracking framework for King County, WA; technical scenario analysis and modeling of how the City of Seattle could reduce GHG emissions to near zero by 2050; and providing the U.S. Environmental Protection Agency with monthly reviews of recent developments in offset markets.

Chelsea has a bachelor’s degree in atmospheric science from the University of California–Berkeley, and a master’s degree in global change science and policy from Yale University School of Forestry & Environmental Studies. She has also lived and worked in Latin America.
