7. 2 Policies and Scenarios for Renewables, Societal and Global Challenges
Summary / Abstract:
Until 2050 Germany could abate its GHG emissions by 100% and lower its raw material consumption (RMC) by almost 70%. This is the first study addressing in a systemic approach climate mitigation and resource efficiency on a regional and global scale. The RESCUE-study (“Resource-efficient Pathways towards Greenhouse-Gas- Neutrality”) analyzes six scenarios that describe possible transformation pathways towards a GHG-neutral and resource-efficient Germany in 2050. The scenarios focus on different levels of ambition towards achieving GHG-neutrality (GreenLate – slow transition, GreenSupreme – fast transition), enhanced material efficiency (GreenMe), and a wider implementation of sustainable life-styles (GreenLife). The implementation and maintaining of the needed technologies comes with various synergies and trade-offs. For instance, increasing efficiency leads to less material use, this lowering energy demands – in the same time building up a low-carbon system creates increasing demand for materials (e.g. copper) and resources (e.g. land).
