Meredydd Evans

Integrat Analys & Dec Sci Team


Meredydd Evans is an energy policy and finance expert with over 20 years of international experience. She has worked on energy efficiency and clean energy policies and projects in numerous countries. She is a senior staff scientist at the Pacific Northwest National Laboratory, where she is managing a program on international sustainable energy, including efforts on building energy efficiency, policies and mechanisms to reduce short-lived forcers, and energy data for policy and clean energy investments, among others. Her work covers both global assessments as well as country-specific research in China, India, Vietnam, Russia and elsewhere. She began working at PNNL in 1994, and she was seconded to the International Energy Agency in Paris from 2002-2006. While at the IEA, she served as Acting Head of the Non-Member Country Division and she wrote two books on energy policy. Both works have been used by national governments in designing policies, laws and regulatory systems. Meredydd is fluent in five languages and has published numerous books and articles.
