Barbara Haya

Research Fellow, California Institute for Energy and Environment, UC Berkeley

Barbara Haya’s work combines research and policy outreach with a focus on the effectiveness of carbon offset programs. She leads the Berkeley Carbon Trading Project, which examines the outcomes of California’s carbon offset program and performs analysis on any proposed expansion or modification to the program.


Haya is also helping the University of California system develop its strategy for procuring carbon offsets for use towards meeting the system’s carbon reduction and neutrality goals.

Haya holds a Ph.D. from UC Berkeley’s Energy and Resources Group, where she studied the outcomes of the Kyoto Protocol’s offset program, the Clean Development Mechanism, and worked closely with NGOs at the international climate change negotiations in support of offset program reform. Prior to returning to UC Berkeley, she worked with the Union of Concerned Scientists and then Stanford Law School contributing analysis on the design and implementation of California’s global warming law.
