11 INTERGOVERNMENTAL PANEL ON CLIMATE CHNGE (IPCC) Long-Term Stabilization Profiles ~$100/tCO 2 A2 B1

12 INTERGOVERNMENTAL PANEL ON CLIMATE CHNGE (IPCC) Long-Term Stabilization Profiles <$25/tCO 2 ~$100/tCO 2

13 The lower the stabilisation level the earlier global emissions have to go down peak in 10yrs peak in 25yrs

20 Nakicenovic # 20 2008 Global Energy Assessment Towards a more Sustainable Future The magnitude of the change required is huge The magnitude of the change required is huge The challenge is to find a way forward that addresses all the issues simultaneously The challenge is to find a way forward that addresses all the issues simultaneously A paradigm shift is needed: energy end- use efficiency, new renewables, advanced nuclear and carbon capture and storage. A paradigm shift is needed: energy end- use efficiency, new renewables, advanced nuclear and carbon capture and storage. Source: Johansson, 2005

21 Some Research Areas for future collaboration (1)Integrated Assessment Framework: Modeling of long-term global and regional transitions (2)Decision Making under Uncertainty (3)Energy services: Understanding heterogeneity of energy consumers (4)Global Energy Assessment (GEA)

22 Confronting the Challenges of Energy for Sustainable Development: The Role of Scientific and Technical Analysis Sustainable Development: The Role of Scientific and Technical Analysis and its international partners present the www.GlobalEnergyAssessment.org

23 GEA Knowledge Clusters ●Cluster I: Major Global Issues and Energy –assessment of the Challenges ●Cluster II: Energy Resources and Technological Options –assessment of the Components available to build future energy systems ●Cluster III: Possible Sustainable Futures –assessment of how to combine the Components to create Systems that address the Challenges – Scenario development ●Cluster IV: Policies Advancing Energy for Sustainable Development –assessment of the Policies needed to address the Challenges and realize the Systems
