Delhi Smog Alert: Haryana's Jhajjar Fuels Pollution Crisis
18 Dec, 2025
Summary
- Jhajjar contributes 16.5% of Delhi's PM2.5, surpassing the city's transport sector.
- Nearly two-thirds of Delhi's pollution originates from outside the city limits.
- Thermal power plants in Jhajjar are identified as a major contributor to emissions.
Even after the end of the stubble-burning season, a substantial portion of Delhi's pollution originates from neighboring regions. On Wednesday, Jhajjar in Haryana contributed 16.5% to Delhi's PM2.5 levels, a figure higher than the city's own transport sector. Data from the Centre's Decision Support System (DSS) indicates that close to two-thirds of Delhi's pollution load originated from outside the capital.
Other areas within the National Capital Region (NCR) also showed significant contributions, with Rohtak, Bhiwani, and Sonipat adding to the cross-boundary pollution. Experts attribute Jhajjar's high impact to its two coal-based thermal power plants, emphasizing how prevailing winds can transport pollutants easily to Delhi. While the DSS uses an older emissions inventory, major pollution sources like these power plants remain consistent contributors.
