William E. Rees is a human ecologist, ecological economist, professor, and former director of the University of British Columbia’s School of Community and Regional Planning. Since 1969, Rees has been at the forefront of the fields of sustainable development, ecology, and ecological economics, producing countless publications and ideas, and contributing to a wide variety of collaborative projects focused on the public policy and planning implications of global environmental trends and the necessary ecological conditions for sustainable socioeconomic development.

Dr. Rees is best known as the originator of the Ecological Footprint concept, and the co-developer of the quantitative analysis model that estimates humanity’s ecological impact on the ecosphere in terms of appropriated ecosystem area. Twenty years after the development of the Ecological Footprint analysis model, governments of all levels, from municipal to international, major international organisation sand agencies, and many NGOs have incorporated Ecological Footprint analysis into their planning processes. His ground-breaking work has shifted the global paradigm for policy makers and academics engaged in the struggle for sustainable socioeconomic development.
