India’s Centre for Research on Energy and Clean Air (CREA), an independent research body, has released a countrywide report on October air quality, detailing sector-wise PM2.5 contributors across states and major cities.

Urban dust

According to the report, 44 per cent of Mumbai’s PM2.5 comes from urban fugitive dust, which includes construction activity and dust from unpaved roads. Industries and power generation facilities account for 28 per cent of emissions. Transportation contributes 11 per cent, while domestic activities account for 10 per cent. Agriculture and waste burning are among the other, comparatively smaller contributors.
