While Germany has introduced a comprehensive ecological tax reform (ETR) in 1999, Poland has taken only first steps into this direction. In order to intensify the exchange between German and Polish experts from politics, research and NGOs, the Polish Ministry of the Environment together with the German Ministry of the Environment organised a workshop in Warsaw during which the design of the German ecological tax reform and its implications were discussed. Helen Lückge, Fellow at Ecologic, presented the economic implications of the German ETR.

On 12 October 2005, the Climate Policy Center and the German Marshall Fund of the United States conducted an international workshop designed to clarify and improve R&D strategy for climate change solutions. The one-day meeting helped experts in the United States and Europe focus on key strategic questions about relevant R&D priorities and policies. Senior Fellow Markus Knigge gave a presentation on the impacts of the German Renewable Energy Sources Act and the Eco-taxes on innovation and commercialization of clean technologies.
