Ecologic analyses, within the framework of this project, the institutional interactions between international treaty systems and European environmental instruments. Although they are negotiated separately, they affect each other's performance and effectiveness. Such 'institutional interaction' will inevitably cause conflicts if regulatory approaches are incompatible. If approaches are mutually reinforcing, however, it may also create synergies. If not addressed properly, inter-institutional conflicts can inhibit and counteract the effectiveness of international environmental co-operation.

WTO Ministerial Conferences' site events represent unique occasions for trade and environment experts to meet and exchange opinions. Large numbers of high level policy makers, researchers and academics as well as representatives from civil society groups from all over the world come together to discuss recent developments in the area, conflicts between trade, environment and sustainable development, and potential solutions. Ecologic participated in a number of the site events at the Seattle Ministerial and reported their outcomes to the German Federal Environmental Agency.
