Enhanced expertise with the analysis and the assessment of long-term global and world-regional E3 (energy-economy-environment) scenarios

ECS-IIASA has developed a number of global energy-economic-environmental (E3) scenarios. These include reference scenarios contributed to the recently published Special Report on Emissions Scenarios (SRES, 2000) of the Intergovernmental Panel on Climate Change (IPCC). In this context ECS-IIASA has undertaken a comparison based on the main scenario indicators for some POLES (REF 1999 and 2001) and MESSAGE (A1B for SRES and, mainly in the summary, A1B-550) scenarios.

The analysis has highlighted the main common points and divergence with respect to scenario results on the scenarios� primary energy mix, electricity generation, carbon emissions, as well as carbon and energy intensities putting particular emphasis on the medium term paths in the context of longer term trajectories.

Some of the results indicate that the three principal measures contributing to the goal of limiting atmospheric GHG concentrations are: (1) demand reduction due to enhanced energy conservation, (2) fuel switches away from carbon-intensive fuels, and (3) carbon scrubbing and sequestration.

The full results of this comparison can be found in the final report.
