Based on empirical evidence, the paper discusses the impact of a consulting and information program for the improvement of material productivity with regard to economic and environmental targets for Germany. The instrument used in the analysis is the integrated economic-environmental model PANTA RHEI, which is parameterized econometrically. The paper presents the model and shows in a baseline forecast that without policy changes, sustainability will be violated in both the economic and the environmental dimensions. This applies to the latter particularly with regard to land use and material consumption. The alternative simulation that introduces a consulting and information program for the improvement of material productivity yields a win-win result: growth rates of GDP and employment are rising, the public debt is reduced, and material consumption is much lower than in the baseline and remains at the actual level, which means that a decoupling of growth and material consumption is possible.
