A multi-scale health impact assessment of air pollution over the 21st century

Ozone and PM2.5 are current risk factors for premature death all over the globe. In coming decades, substantial improvements in public health may be achieved by reducing air pollution. To better understand the potential of emissions policies, studies are needed that assess possible future health impacts under alternative assumptions about future emissions and climate across multiple spatial scales. Authors used consistent climate–air-quality–health modeling framework across three geographical scales (World, Europe and Ile-de-France) to assess future (2030–2050) health impacts of ozone and PM2.5 under two emissions scenarios (Current Legislation Emissions, CLE, and Maximum Feasible Reductions, MFR).
