Clearing the Air Seminar Series was organised by the Initiative on Climate, Energy and Environment (ICEE) at the Centre for Policy Research (CPR). This series aimed to promote sustained and informed public understanding around the data, impacts, sources and policy challenges involved in clearing Delhi’s air. While it focused on the context of Delhi, the series also reflected on the fact that the problem extends far beyond Delhi. The seminar series presented the work of experts in a range of areas to help promote informed public discussion about what changes are needed, what is possible, and how to get it done. Clearing the air in terms of knowledge and public information, the organizers hope, will make a small contribution toward actually clearing Delhi’s air.
