Achieving the Paris Agreement and SDGs can result in low-carbon, healthy, resilient and equitable societies with high well-being for all  . Given the overlap in sources of greenhouse gases  and co-pollutants in energy systems, strategies that pursue GHG emission reductions and improvements in energy efficiency hold significant potential health co-benefits through air pollution emission reductions  . Air quality improvements alone can substantially offset, or most likely exceed, mitigation costs at the societal level . Pursuit of a mitigation pathway compatible with warming of +1.5℃ with associated cleaner air, avoided extreme events and improved food security and nutrition could result in 152 + 43 million fewer premature deaths worldwide between 2020 and 2100 compared with a business-as-usual scenario . Reaching the Paris Agreement could result in an annual reduction of 1.18 million air pollution-related deaths, 5.86 million diet- related deaths and 1.15 million deaths due to physical inactivity across nine major economies by 2040 . In Europe, a mitigation scenario compatible with RCP2.6 could reduce total pollution costs, mostly from PM2.5, by 84%, with human health benefits equal to more than Euro 1 trillion over five years . In the EU, ambitious climate mitigation policies could reduce years of lost life due to fine particulate matter  from over 4.6 million in 2005 to 1 million in 2050, reduce ozone-related premature deaths from 48,000 to 7,000 and generate health benefits of Euro 62 billion yr-1 in 2050 .
