Andrew Leach is an energy and environmental economist who holds a joint appointment with the University of Alberta’s Faculties of Arts and Law. With more than two decades of experience as a researcher, Leach is also a co-director of the Institute for Public Economics at the U of A. Prior to these appointments, Leach was a professor in the Alberta School of Business.

Leach holds a bachelor’s degree in environmental science and a master’s degree in economics from the University of Guelph, a doctoral degree in economics from Queen’s University and a master’s degree in constitutional law from the U of A. Before joining the U of A, he was a teaching fellow at Queen’s University in the economics department, then an assistant professor at HEC Montréal’s Institute of Applied Economics and later a visiting scholar at the Strategic Policy Branch of Environment Canada. He also served as academic director of the Centre for Applied Business Research in Energy and the Environment (CABREE) at the U of A’s School of Business between 2014 and 2022.

By drawing on his expertise in constitutional law, environmental science and environmental economics, Leach has advised various levels of government on climate change and oil and gas industry policies. Since 2011, he has appeared as an expert witness before the Senate and the House of Commons, and in 2015, he served as chair of the Government of Alberta’s Climate Leadership Panel. Over the years, Leach has served as an economics and policy consultant for Environment Canada, the National Roundtable on the Environment and the Economy (NRTEE), the Auditor General of Alberta, Alberta Environment, Alberta Finance and Enterprise, and Alberta Energy. Leach is also a contributing writer to a variety of news publications, with over 200 articles published by major media outlets such as CBC News, The Globe and Mail, and Maclean’s.

Outside of his academic endeavours, Leach volunteers his time as a board member of the REACH Edmonton Council for Safer Communities. He also enjoys cycling and serves on the board of Edmonton Juventus Cycling Club.
