Air Emission Estimates and Inventories

Data-based Air Quality Management: From Science to Solutions – Case Study of Indore

Wednesday, June 11, 2025
9:00am – 9:20am ET
Location: 302A
Indore is one of the non-attainment cities in India under the National Clean Air Programme (NCAP) implemented by the Indian Ministry of Environment, Forest and Climate Change (MoEFCC). The NCAP targets a reduction of up to 40% in PM10 by 2025-2026. The Clean Air Catalyst (CAC) project supported the City of Indore with understanding emission sources and identifying mitigation measures. We developed detailed emission inventory using primary and secondary activity data and performed source apportionment. We also identified mitigation measures for the transport sector and estimated net emissions reduction. We developed a suite of measures for mitigating transport emissions in Indore that included enhancing vehicle scrappage, shifting from private to public transport and cleaning road dust, among other measures. Air quality modelling was performed for baseline and the mitigation scenario to understand the impact of the proposed mitigation measures. The team used the WRF-Chem model instrumented with tracking to be able to understand regional contributions.
