Air Quality Benefits of Climate Action in Cities Around the World
Representatives of nine cities from around the world analysed air quality and health benefits of climate actions in their cities at a workshop organised by C40, the leading global network of cities committed to addressing climate change.
At the workshop in London, from 7th to 9th November, experts from CERC, C40, Buro Happold and the London School of Hygiene and Tropical Medicine worked with representatives from Istanbul, Medellin, Quezon City, Quito, Mexico City, Buenos Aires, Hanoi, Athens and Karachi. The city representatives brought details of specific climate actions to which their city is committed, including tightening vehicle emissions standards, new public transport schemes, building solar energy generation plants and reducing industrial emissions. During the event CERC's Mark Jackson and Matt Williams provided expert guidance on air quality benefits of the actions. All nine cities were able to produce numerical estimates of benefits from their actions, including air quality concentration improvements and consequent improvements in life expectancy for the city populations, and the benefits of scaling up their actions to more ambitious targets.
