William Rees

William Rees, FRSC (born December 18, 1943), is Professor Emeritus at the University of British Columbia and former director of the School of Community and Regional Planning (SCARP) at UBC.

Rees taught at the University of British Columbia from 1969–70 until his retirement in 2011–12, but has since continued his writing and research.

His primary interest is in public policy and planning relating to global environmental trends and the ecological conditions for sustainable socioeconomic development.

He is the originator of the "ecological footprint" concept and co-developer of the method.

William Rees received his PhD degree in population ecology from the University of Toronto.

He founded SCARP's '"Environment and Resource Planning" concentration and from 1994 to 1999 served as director of the School.

Rees' book on ecological footprint analysis, Our Ecological Footprint (co-authored with then PhD student Dr Mathis Wackernagel), was published in 1996 and is now available in English, Chinese, French, German, Hungarian, Italian, Japanese, Latvian, and Spanish.

Much of Rees' work is in the realm of ecological economics and human ecology including behavioural and cultural barriers to sustainability.

He is best known in these fields for the co-development of ecological footprint analysis with his then PhD student Mathis Wackernagel.

The ecological footprint is a quantitative tool that estimates humanity's ecological impact on the ecosphere in terms of appropriated ecosystem (land and water) area.

This research reveals the fundamental incompatibility between continued material economic growth and ecological security, and has helped to reopen debate on human carrying capacity as a consideration in sustainable development.

Rees is a founding member and recent past-President of the Canadian Society for Ecological Economics.

He is also a Fellow at the Post Carbon Institute, a co-investigator in the "Global Integrity Project" aimed at defining the ecological and political requirements for biodiversity preservation, a founding director of the One Earth Initiative and a Director of the Real Green New Deal project.

A dynamic speaker, Rees has been invited to lecture on areas of his expertise across Canada and the US, as well as in Australia, Austria, Belgium, China, Finland, France, Germany, Hungary, Japan, Mexico, the Netherlands, Norway, Indonesia, Italy, Korea, the former Soviet Union, Spain, Sri Lanka, Sweden and the UK.

Rees' academic interests are in the following subject matter fields:

Rees has said that the "enlightenment project," rooted as it is in Cartesian dualism, has resulted in a techno-industrial society that sees itself as somehow separate from the biophysical world.

This dualism and its expansionary-materialist worldview are the basis of many of the "environmental problems" facing humankind.

In 1997, UBC awarded William Rees a Senior Killam Research Prize.

Rees was a member of the winning team receiving the City of Barcelona 2004 Award (Multimedia Category) for the exhibition Inhabiting the World. In 2000, The Vancouver Sun recognized him as one of British Columbia's top "public intellectuals."

Previously he was a recipient of a 2007 Trudeau Fellowship, an annual prize awarded by the Pierre Elliott Trudeau Foundation "...in recognition of outstanding achievement, innovative approaches to issues of public policy and commitment to public engagement", and in 2006 he was elected as a Fellow of the Royal Society of Canada (FRSC).

In 2012 he was awarded the 2012 Blue Planet Prize (jointly with Dr Mathis Wackernagel), the 2012 Kenneth Boulding Prize in Ecological Economics (ISEE), and an honorary Doctoral Degree, Laval University.

Rees has received a Dean's Medal of Distinction (UBC Faculty of Applied Science 2016) and the 2015 Herman Daly Award in Ecological Economics (USSEE).
