GAINS Asia

  1. 1. Pallav Purohit International Institute for Applied Systems Analysis (IIASA) Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS)-Asia Asia-Europe Scientific Cooperation Day Vienna, 24 October 2007
  2. 2. GAINS GHG-Air pollution INteractions and Synergies model • Extension of Regional Air Pollution Information and Simulation (RAINS) integrated assessment model for air pollution to GHGs • CO2, CH4, N2O, HFC, PFC, SF6 in addition to SO2, NOx, VOC, NH3, PM • Currently implemented for 43 countries in Europe (funded by the Netherlands), • GAINS-Asia (China and India) project to be completed at the beginning of the next year (funded by DG- Research)
  3. 3. The multi-pollutant/multi-effect approach of the RAINS model Costs of emission controls PM SO2 NOx VOC NH3 Health impacts: √ √ √ √ √ Quantification of impacts PM O3 √ √ Quantification of physical Vegetation damage: √ √ and chemical interactions O3 in the atmosphere Acidification √ √ √ Eutrophication √ √
  4. 4. Policy analysis with the GAINS cost-effectiveness approach Energy/agricultural Driving forces (i. e. population projections and economic growth) Emission control options Emissions Costs OPTIMIZATION Atmospheric dispersion Health and environmental Environmental impacts targets
  5. 5. The GAINS approach for identifying cost-effective emission control strategies (GHG-Air pollution INteractions and Synergies ) IIASA’s GAINS optimization model PM SO2 NH3 NOx VOC GHGs Health Eutrophication Acidification Policy Ozone target on GHG emissions Policy targets on air quality
  6. 6. GAINS-Asia is freely accessible at the Internet http://www.iiasa.ac.at/web-apps/apd/gains/
