Cleaning the air in South Asia: Why science and cooperation matter

IIASA researchers Pallav Purohit and Zbigniew Klimont examined the urgent challenge of air pollution in South Asia and the opportunities to address it through science-based policy and regional cooperation. In the run-up to the recent International Vienna Energy and Climate Forum, they drew on recent research and real-world examples to highlight how integrated approaches to energy, climate, and air quality can deliver cleaner air, improved health, and more resilient economies for nearly one billion people.
