Delivering Air Quality, Health, and Climate Co-Benefits in Salon 9
14:45 - 16:15
Climate change and air pollution are interrelated in ways that are relevant for cities. Climate change can influence air pollution through changes in meteorology, whereas air pollutant emissions themselves can influence regional climate as short-lived climate pollutants. Perhaps most importantly, most actions to decrease greenhouse gas (GHG) emissions reduce air pollutant emissions from the same sources, leading to important co-benefits for air quality and health. Since ambient air pollution is responsible for about 4.5 million premature deaths globally each year, actions to slow climate change will have significant benefits for global health. As cities work toward air quality and climate mitigation goals, there is opportunity to plan to address both problems simultaneously. This session aims to improve understanding of the links between air pollution, climate change, and public health, and from past efforts to quantify co-benefits with a focus on developing effective policies. Further, we hope to learn from the experience of city practitioners about how co-benefits can and have been used successfully to motivate GHG emission reductions and air quality improvements. We will also discuss opportunities for joint air pollutant/GHG emissions inventories and how air quality and health co-benefits can be estimated and delivered in practice, and ways to strengthen that capacity.
