Join Vital Strategies for a webinar launching its new report, Prioritizing Evidence Gaps: Air Pollution and Health Impacts of Climate Action. Current evidence suggests climate actions will result in larger health gains via air pollution reductions than via CO2 and temperature reductions. At the same time, more research is needed to precisely assess the effectiveness of clean air and climate actions being taken, considering how actions reduce specific health-damaging source emissions. Vital Strategies and Wellcome Trust conducted a rapid scoping activity to identify and prioritize gaps in the evidence base that may be limiting cities' and countries' abilities to demonstrate the health impacts of climate mitigation actions targeting combustion-source air pollution.
