WORKSHOP on GLOBAL AIR POLLUTION TRENDS UP TO 2030

January 27-28, 2005

International Institute for Applied Systems Analysis (IIASA)
Laxenburg, Austria

The continuing rise in economic wealth will further intensify the pressure from the driving forces of air pollution, both in industrialized and developing countries. However, worldwide data on air pollution show that, once nations reach a certain level of economic development, they manage to control their emissions and, thus, effectively improve local and regional air quality. While such trend reversals are evident for some air pollutants, there is still little indication of a similar tendency for greenhouse gases that have negative impacts on global climate.

The workshop reviewed the medium-term perspectives on the development of the emissions of the various air pollutants across the globe up to 2030. It assessed the findings from top-down and bottom-up approaches, and compared results of medium-term studies with trends suggested by long-term projections. While focusing on the traditional air pollutants, the workshop also considered related trends in greenhouse gas emissions. A special session was devoted to emission projections for black carbon and organic carbon.

The workshop included the following sessions:

• Medium-term emission projections for air pollutants up to 2030
• Long-term emission scenarios
• Emission trends of air pollutants and greenhouse gases
• Emission scenarios for carbonaceous particles (black carbon, organic carbon)
• Assessments of future air quality and impacts

The workshop has been organized as part of the "Atmospheric Sustainability" subproject of the "ACCENT" European Network of Excellence on Atmospheric Composition Change.
