INTERGOVERNMENTAL PANEL ON CLIMATE CHNGE (IPCC)

The main finding from the comparison of SRES and new scenarios in the literature is that (high agreement, much evidence):● The ranges of main driving forces and emissions

have not changed very much● Population scenarios from major demographic

institutions are lower than they were at the time of TAR

● Regional medium-term (2030) economic projections for some developing country regions are currently lower than the highest scenarios used in TAR.

● The most noticeable changes are lower projections of SOx and NOx emissions.

Global Mitigation Challenges• Significant mitigation potential by 2030 and

beyond at costs <$100/tCO2

• Technological change essential for reducing mitigation costs and increasing potentials

• “Upfront” investments reduce longer-term mitigation costs and increase potentials

• High emissions baselines have higher mitigation costs and higher stabilization levels.

• Investment in RD&D and diffusion reduce mitigation costs
