This Website documents more than 20 years of US-German collaboration for more sustainable land-use in cities and municipalities. For the latest activities of the Network, please go to and register there.

In 2000, the United States Environmental Protection Agency (EPA) and the German Federal Ministry of Education and Research (BMBF) continued a cooperative effort to share information and evaluate new solutions and tools for the redevelopment of contaminated sites. By using model projects to demonstrate exemplary approaches to site redevelopment, the working group aims to evaluate new approaches and technologies and then transfer lessons learned throughout the U.S. and Germany. Since 2012, the working group is in Phase 5 with a focus on developing, evaluating, and refining tools and models for using portfolios of land so as to increase the resilience of environmental, social, and economic systems; and expanding the capacity of these systems to provide goods and services that sustain human life.
