Benefits of integrating air pollution and climate change policy

Global climate change has resulted primarily from the accumulation of carbon dioxide (CO2) and other greenhouse gases (GHGs) in the atmosphere over the last 150 years. However, recent studies indicate that, on average, 40 per cent of the potential warming by GHGs is being masked by certain aerosols (and aerosol-cloud interactions) that increase the reflection of sunlight.
