Norms<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Bharat Stage (BS) emission norms are India\u2019s legally enforced standards to regulate air pollutants emitted by motor vehicles.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Framed by the Ministry of Environment, Forest and Climate Change (MoEFCC) and implemented by the Central Pollution Control Board (CPCB), these norms are broadly aligned with European emission standards (Euro norms) and apply to all new vehicles manufactured and sold in the country.<\/span><\/li>\n<\/ul>\n<h3><b>Evolution of Bharat Stage Norms<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India has progressively tightened vehicular emission standards to address worsening urban air pollution:<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">BS I \u2013 Introduced nationwide in 2000<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">BS II \u2013 2001 (Delhi first), nationwide by

Implemented directly from BS IV in April 2020, skipping BS V<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3><b>Pollutants Regulated<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">BS norms prescribe upper limits for key vehicular pollutants, including:<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">Carbon Monoxide (CO)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">Hydrocarbons (HC)<\/span><\/li>\n<li style=\"font-weight: 400;\"

(PM)<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Each successive BS standard tightens these limits significantly.<\/span><\/li>\n<\/ul>\n<h3><b>Other Features<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Advanced emission-control technologies, such as:<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">Diesel Particulate Filters (DPF)<\/span><\/li>\n<li style=\"font-weight: 400;\"

protection by reducing pollutants linked to respiratory and cardiovascular diseases.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Environmental benefits, including lower smog formation and black carbon emissions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Technological upgradation of India\u2019s automobile industry.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Global alignment, improving export competitiveness of Indian vehicles.<\/span><\/li>\n<\/ul>\n<h2><b>Why Delhi Has Mixed-Standard Vehicles<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Delhi\u2019s <\/span><b>mixed BS fleet<\/b><span style=\"font-weight: 400;\"> exists because the Capital adopted stricter norms earlier than the rest of India due to severe air pollution.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Delhi implemented BS II in 2001, BS III in 2005 and BS IV in 2010\u2014well ahead of national timelines.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Although BS VI became mandatory nationwide in April 2020, vehicles from other states with older standards continue to enter the city, resulting in a mix of emission norms on Delhi\u2019s roads.<\/span><\/li>\n<\/ul>\n<h2><b>Why Older Vehicles Contribute More to Air Pollution<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Older vehicles emit significantly higher levels of harmful pollutants because they lack advanced emission-control technologies.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Diesel vehicles, in particular, release large amounts of nitrogen oxides and fine particulate matter, major contributors to smog and respiratory and cardiovascular diseases.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">They also emit volatile organic compounds that form secondary pollutants in the atmosphere.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In addition, black carbon from diesel exhaust not only damages public health but also accelerates climate warming, making older vehicles especially polluting.<\/span><\/li>\n<\/ul>\n<h3><b>Scale of Older, High-Polluting Vehicles in Delhi-NCR<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A significant share of vehicles in Delhi-NCR remains highly polluting.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Government assessments indicate that nearly <\/span><b>37% of vehicles<\/b><span style=\"font-weight: 400;\"> in the region comply only with older <\/span><b>Bharat Stage I, II or III norms<\/b><span style=\"font-weight: 400;\">, making them major contributors to the air quality crisis.<\/span><\/li>\n<\/ul>\n<h2><b>BS VI vs BS IV: What Changed in Emission Standards<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">BS VI emission norms impose far tighter pollution limits than BS IV.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">For petrol vehicles, nitrogen oxide (NOx) limits are reduced by about 25%.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">For diesel vehicles, NOx emissions must fall by nearly 68%, while particulate matter (PM) emissions are cut by around 82%.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">BS VI vehicles also run on much cleaner, low-sulphur fuel, enabling advanced emission-control technologies to operate effectively.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In addition, BS VI introduces more stringent testing procedures, closer to real-world driving conditions, to ensure lower on-road emissions.<\/span><\/li>\n<\/ul>\n<p><b>Source:<\/b> <strong><a
