Abstract

This report describes initial policy analyses with the Greenhouse gas – Air pollution Interactions and Synergies (GAINS) model. It summarizes the exogenous projections on energy and agricultural activities up to 2030 and discusses the resulting implications on air quality and greenhouse gas emissions. An illustrative scenario explores the health benefits from a substitution of solid fuels in households by LPG and explores the side-effects on greenhouse gas emissions. The paper summarizes the optimization methodology that has been developed for the GAINS-Asia model and presents a range of alternative strategies to improve air quality and reduce greenhouse gas emissions. It shows that with a targeted approach, emission control costs can be reduced by up to 80 percent compared to an across-the-board application of technologies. Furthermore, the paper presents systematic analyses of the costs (i.e., cost curves) for reducing health impacts from fine particulate matter as well as for reducing greenhouse gas emissions.
