　　Abstract

　　A wide body of scientific literature outlines the co-control of greenhouse gas and air pollutant emissions, offering welcome local near-term benefits to efforts directed at the mitigation of long-lived greenhouse gases. However, a systems perspective can also reveal important opportunities for controlling local air quality in a way that maximizes benefits to climate change. Such strategies could actively address emissions of short-lived climate pollutants (BC, CH4) that could reduce the rate of temperature increase in the near term and off-set potential cooling from the reduction of SO2 and OC that are required for achieving local air quality standards. Another a strategy could focus on sources that co-emit short-lived air pollutants and long-lived greenhouse gases. Analysis shows that there is a host of practical measures that do not only achieve both objectives, but are also beneficial from a social planner’s economic perspective, i.e., which will not hamper economic development in the long run. The presentation will provide examples for both approaches and present a model framework that helps identifying such win-win measures.
