Impacts of Short-Lived Air Pollutants (ECLIPSE)

ECLIPSE is conducting research to increase knowledge about emissions of ozone and aerosols, which act as short-lived climate forcers, and identify concrete, cost-effective abatement measures.


Current climate policies do not address short-lived substances such as ozone and aerosols, including black carbon. These substances, called short-lived climate forcers (SLCFs), make significant contributions to climate change, especially in the near term, and also affect air quality.

The ECLIPSE project is developing and assessing emission abatement strategies for SLCFs to provide scientifically-based advice to policy makers on measures that both mitigate climate change and improve air quality. The project is building on existing knowledge and using state-of-the-art techniques to increase understanding of the different physical and chemical properties and the associated impact of SLCFs. The research will also study the interactions between SLCFs and clouds.

The project is using three case studies, Eastern Europe, China, and the Arctic, to better understand how SLCFs interact with the atmosphere.

IIASA Research

Researchers with IIASA’s Mitigation of Air Pollution and Greenhouse Gases program are providing expertise on emissions and the economic costs of emission reduction measures, using the GAINS model at a global level and for examining SLCF emissions from Eastern Europe and China.
