A recent mid-year assessment by the <strong>Centre for Research on Energy and Clean Air (CREA)<\/strong> has revealed sobering data: from January to June 2025, Delhi recorded <strong>29 days of &#8216;very poor&#8217; air quality<\/strong> and only <strong>three days that met the &#8216;good&#8217; category<\/strong>.

This aims to eliminate highly polluting older automobiles from city roads.<\/p>\n\n\n\n<p><strong>Pros of the ELV ban:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduces emissions from outdated internal combustion engines.<\/li>\n\n\n\n<li>Encourages the adoption of newer, cleaner vehicles.<\/li>\n\n\n\n<li>Supports the electric vehicle push under Delhi\u2019s EV policy.<\/li>\n<\/ul>\n\n\n\n<p><strong>Limitations:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The ELV policy alone <strong>cannot offset emissions<\/strong> from other sources.<\/li>\n\n\n\n<li><strong>Enforcement remains patchy<\/strong>, especially in informal transit segments.<\/li>\n\n\n\n<li>It targets a <strong>limited segment<\/strong> of vehicles, missing industrial trucks, construction equipment, and even generators.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">The Other Culprits: Year-Round Emission Sources<\/h2>\n\n\n\n<p>CREA\u2019s report highlights that the <strong>focus on vehicular emissions alone is too narrow<\/strong>. The broader pollution ecosystem includes:<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"1\">\n<li><strong>Construction Dust<\/strong>: One of the top sources of PM10 and PM2.5 emissions in Delhi. Enforcement of dust control norms remains weak.<\/li>\n\n\n\n<li><strong>Waste Burning<\/strong>: Open garbage burning continues across Delhi\u2019s fringes despite being illegal. This adds to black carbon and PM2.5 concentrations.<\/li>\n\n\n\n<li><strong>Biomass and Domestic Fuels<\/strong>: Low-income households still rely on wood, coal, and kerosene, particularly in peri-urban areas.<\/li>\n\n\n\n<li><strong>Industrial Pollution<\/strong>: Unauthorized factories and brick kilns operate in and around Delhi, especially in Ghaziabad and Faridabad, contributing heavily to emissions.<\/li>\n\n\n\n<li><strong>Diesel Generators<\/strong>: Due to erratic power supply in some localities, DG sets are used for backup, adding to local pollution hotspots.<\/li>\n\n\n\n<li><strong>Transboundary Pollution<\/strong>: Emissions from Punjab, Haryana, and Uttar Pradesh drift into Delhi during specific seasons.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Delhi Needs: A Multi-Sectoral, Science-Backed Response<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/blog.aquartia.in\/wp-content\/uploads\/2025\/07\/Gemini_Generated_Image_rxbz36rxbz36rxbz-1024x1024.png\" alt=\"\" class=\"wp-image-2659\" srcset=\"https:\/\/blog.aquartia.in\/wp-content\/uploads\/2025\/07\/Gemini_Generated_Image_rxbz36rxbz36rxbz-1024x1024.png 1024w, https:\/\/blog.aquartia.in\/wp-content\/uploads\/2025\/07\/Gemini_Generated_Image_rxbz36rxbz36rxbz-300x300.png 300w, https:\/\/blog.aquartia.in\/wp-content\/uploads\/2025\/07\/Gemini_Generated_Image_rxbz36rxbz36rxbz-150x150.png 150w, https:\/\/blog.aquartia.in\/wp-content\/uploads\/2025\/07\/Gemini_Generated_Image_rxbz36rxbz36rxbz-768x768.png 768w, https:\/\/blog.aquartia.in\/wp-content\/uploads\/2025\/07\/Gemini_Generated_Image_rxbz36rxbz36rxbz-1536x1536.png 1536w, https:\/\/blog.aquartia.in\/wp-content\/uploads\/2025\/07\/Gemini_Generated_Image_rxbz36rxbz36rxbz.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>To truly improve air quality, Delhi must adopt a <strong>multi-pronged strategy<\/strong> that targets <strong>all major pollution sources<\/strong>:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. <strong>Decarbonize Urban Transport<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Push for more public transport and rapid electrification of buses and autorickshaws.<\/li>\n\n\n\n<li>Incentivize walking and cycling infrastructure.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>Strict Construction and Demolition (C&amp;D) Regulation<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enforce real-time monitoring of large construction sites.<\/li>\n\n\n\n<li>Mandate use of dust barriers, sprinklers, and green netting.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>Control Industrial Emissions<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Relocate illegal factories out of residential areas.<\/li>\n\n\n\n<li>Use AI-based compliance checks and satellite data to identify hotspots.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. <strong>Manage Waste Scientifically<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Scale up municipal composting and biomethanation.<\/li>\n\n\n\n<li>Deploy community incinerators and phase out landfills.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5. <strong>Strengthen Citizen Monitoring and Early Warning Systems<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Improve public access to hyperlocal air quality data.<\/li>\n\n\n\n<li>Expand air pollution awareness campaigns in schools and workplaces.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Lessons from Other Cities<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Beijing:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Adopted a <strong>\u2018regional pollution control zone\u2019<\/strong> approach with surrounding provinces.<\/li>\n\n\n\n<li>Shut down coal plants and restricted high-emission vehicles.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">London:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Introduced <strong>Ultra-Low Emission Zones (ULEZ)<\/strong> with a congestion charge.<\/li>\n\n\n\n<li>Heavily promoted retrofitting of old diesel buses.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Tokyo:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enforced <strong>strict building energy efficiency<\/strong> norms.<\/li>\n\n\n\n<li>Incentivized electric and hybrid cars with subsidies.<\/li>\n<\/ul>\n\n\n\n<p>Delhi can adapt elements of these strategies while tailoring them to local needs, particularly involving <strong>low-income communities<\/strong> in decision-making.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Delhi\u2019s air crisis is not just seasonal or vehicular \u2014 it\u2019s systemic.
