India has 21 of the world’s 30 most polluted cities by PM2.5 concentration. The National Clean Air Programme (NCAP) targets a 40% reduction in particulate pollution by 2025–26, but progress is uneven and the challenge is systemic: industrial emissions, vehicular pollution, construction dust, crop residue burning, and domestic fuel use all contribute.
For industrial operations, air quality management means going beyond compliance with emission norms. A comprehensive approach includes: emission inventory development (identifying all sources and their contributions), dispersion modelling (predicting ambient air quality impacts), best available technology (BAT) assessment, and continuous emissions monitoring.
Construction projects, which SEBI and BRSR now require to disclose, generate significant fugitive dust emissions. Mitigation measures — water spraying, wind barriers, material covering, wheel washing — are well-known but inconsistently applied. Environmental management during construction is as important as operational phase compliance.
RSustain’s air quality practice covers emission inventories, dispersion modelling (AERMOD, ADMS), source apportionment, and mitigation strategy design. We work with both industrial clients and government agencies on air quality improvement programmes.
Clean air is a fundamental human right and a prerequisite for public health. Companies that take air quality management seriously protect both their communities and their social licence to operate.
