International Summit on Integrated Environmental Modeling

This report describes the International Summit on Integrated Environmental Modeling (IEM), held in
Washington, DC on 7th-9th December 2010. The meeting brought together 57 scientists and managers
from leading US and European government and non-governmental organizations, universities and
companies together with international organizations. The Summit built on previous meetings which have
been convened over a number of years, including: the US Environmental Protection Agency (US EPA)
workshop on Collaborative Approaches to Integrated Modeling: Better Integration for Better Decision-
Making (December, 2008); the AGU Fall Meeting, San Francisco (December 2009); and the International
Congress on Environmental Modeling and Software (July 2010). From these meetings there is now
recognition that many separate communities are involved in developing IEM. The aim of the Summit was
to bring together two key groupings, the US and Europe, with the intention of creating a community open
to all.
