“…The three emission control options considered for this study are presented in Table 1. These three different mitigation scenarios were accomplished with a reduction in the (a) transport sector, with the implementation of Bharat Stage VI (BS-VI) norms, which are emission standards placed by the government to regulate the output of air pollutants from internal combustion engines and spark-ignition engine equipment including motor vehicles [25], similar to Euro-6 standards in the European Union; (b) energy sector, by converting coal-based power plants and industries to natural gas; and (c) residential sector, with a fuel shift to liquefied petroleum gas (LPG). Improvement in the air quality was assessed based on reduction in PM and NOx emissions for each of the three control scenarios.…”

Sporadic efforts have been introduced to control emissions in Delhi, but the air quality has declined further due to the rapid development of different sectors. In this study, the impact of various mitigation scenarios on air quality for PM10, ozone, and its precursors are studied using a chemical transport model, namely WRF-Chem. The Emission Database for Global Atmospheric Research emission inventory was modified and introduced into the WRF-Chem model to assess the impact of selected emission control scenarios on different sectors. The simulations were conducted with reduced emissions for these sectors over the study domain: (a) implementation of Bharat Stage—VI norms in the transport sector, (b) conversion of fuel from coal to natural gas in the energy sector, and (c) fuel shift to LPG in the residential sector. The transport sector noted a decrease of 4.9% in PM10, 44.1% in ozone, and 18.9% in NOx concentrations with emission reduction measures. In the energy sector, a marginal reduction of 3.9% in NOx concentrations was noted, and no change was observed in PM10 and ozone concentrations. In the residential sector, a decrease of 8% in PM-10, 47.7% in ozone, and 49.8% in NOx concentrations were noted. The VOC-to-NOx ratios were also studied, revealing the ozone production over the study domain was mostly VOC-limited. As the inclusion of control measures resulted in varying levels of reduction in pollutant concentrations, it was also studied in the context of improving the air quality index. The WRF-Chem model can be successfully implemented to study the effectiveness of any regulated control measures.
