This chapter discusses the links between aerosol as a pollutant and as a climate forcer, and how future changes in aerosol will be affected by policies in both spheres. The chapter starts with some historical background. It then describes how aerosol particles impact human health and the environment and the regulations that exist to limit these effects. It then describes how aerosol is represented as one of several short-lived climate forcers and how the climatic effects of these are compared to long-lived greenhouse gases in carbon budgets and climate metrics. The chapter describes the effects of policies related to air quality and climate, including the co-benefits and trade-offs of these policies. It concludes by summarizing how integrated assessment models allow policymakers to explore many forward-looking or optimized scenarios of future changes in air pollutant and greenhouse gas emissions.
