The United States Society for Ecological Economics (USSEE) hosts biennial meetings to provide a national and international forum that focuses on the latest issues and shares the latest developments in Ecological Economics.

The Fourth Biennial Conference of the USSEE, “Creating Sustainability Within Our Midst: Challenges for the 21st Century,” took place in June 2007 in downtown New York City on the campus of Pace University. Partnering with the Pace Institute for Environmental & Regional Studies as a co-sponsor, the conference offered a variety of themes and special symposia featuring collective interests as well as regional issues and amenities.
