Aggregated assessment of the r² funding initiative

Saving potentials for the r² funding initiative were determined for the developed technologies as part of the integration and transfer project in the ecological categories of accumulated materials, primary energy demand and greenhouse gas emissions as well as the direct economic saving potential. For each research project of the funding initiative, the Department of Life Cycle Engineering in the Chair of Building Physics at the University of Stuttgart (LBP GaBi) and the Institute for Industrial Production (IIP) at the KIT determined the respective saving potentials of the developed technology for implementation in an industrial-scale plant as well as nation-wide implementation. The results were aggregated into four thematic clusters and shown for the funding initiative as a whole.

The applied methods were mainly material and energy flow analyses, estimates of costs and investments as well as aspects of life cycle assessment in line with DIN ISO 14040 and 14044, and are described in detail in Albrecht et al. (2012), Brandstetter et al. (2012) and Ostertag et al. (2012). Operational support was provided by GaBi’s database and software.

Effects on resource productivity

One objective of the r² funding initiative was to contribute to improving resource efficiency. In its Sustainability Strategy, the German government has set itself the target of doubling resource productivity by 2020 compared to 1994. Based on the surveys by LBP and KIT, the Fraunhofer ISI converted the potentials to the database of the indicator "resource productivity". This was done for the original indicator and for the indicator based on so-called resource equivalents. The theoretical nation-wide potential to reduce cumulated materials means a potential resource productivity increase of about five to six percentage points. More details can be found on the German website.
