ICLEI promotes the implementation of short-lived climate pollutant reduction strategies by mobilizing and empowering the health sector and demonstrating the full range of health benefits that can be achieved at the city level. A significant transformation in the current trajectory of air and climate pollutant emissions requires increased engagement, commitment and action at the global, regional, national and local levels. Health arguments can be a powerful incentive and driver for such action, in particular on the city level, where benefits of local policy change translate directly to health benefits among the local population.
