Professor Heather MacLean is an internationally recognized leader in sustainable systems analysis, including life cycle assessment and its application to energy systems and transportation vehicles. Her research has informed the decisions of industry, government and other organizations and has guided regulations such as California's Low Carbon Fuel Standard. Because she is able to bring together disparate groups such as oil-sands producers and NGO's to collaborate on research studies, her work is often instrumental in securing support from regulators, local communities and other stakeholders. She is an Advisor to the World Bank/World Resources Institute for Sustainable Transportation initiative. Professor MacLean is a fellow of the Engineering Institute of Canada.
