- Vehicles: Account for over 80% of emissions, primarily releasing CO, NOₓ, and NMVOCs.
- Industries: Sectors like steel, sugar, cement, and paper contribute to pollutants likesuspended particulate matter (SPM), SOₓ, NOₓ, and CO₂.
- Road Transport: Generates about 12% of India’s CO₂ emissions, according to the International Energy Agency.
- Solid Waste Burning:
- India generates over62 million tons of waste annually, much of which is either burned openly or left in informal dumps, releasing pollutants like dioxins, furans, and PM.
- Agricultural Practices:
- Stubble burningafter paddy and wheat harvests, particularly in Punjab, Haryana, and Uttar Pradesh, significantly increases pollution levels, especially during winter in the National Capital Region (NCR).
- Other agricultural practices like fertilizer application and livestock farming releaseammonia, methane, and particulate matter.
- Domestic Cooking and Heating:
- About62-65% of rural households rely on solid fuels, like biomass and coal, leading to significant indoor and outdoor pollution.
- Coal-Based Power Plants:
- Coal-based thermal power plants without adequate pollution control technologies account for over50% of SO₂, 30% of NOₓ, and 20% of PM emissions in India.
- Improper Use of Pyrolysis:
- Pyrolysis, a process to break down synthetic material, produces fine carbon residue and pollutants. In 2014, the National Green Tribunal (NGT) banned the open burning of used tires for pyrolysis.

- Only60% of NCAP funds have been utilized, with some cities using less than 30%. This inefficiency affects the overall success of pollution reduction efforts.
- Cross-Border Pollution:
- NCAP lacks provisions to tackle pollution from neighboring regions. For example, in Delhi, around two-thirds of air pollution originates from neighboring states.
Global Perspective on Air Pollution: Initiatives and Best Practices
Global Impacts of Air Pollution: Air pollution affects nearly every country, with WHO reporting that 99% of the global population breathes air that exceeds WHO guideline limits. State of Global Air 2021 indicated that air pollution contributed to 8.1 million deaths, underlining the urgency for a global response. Countries worldwide are experimenting with innovative practices and policies to address this issue effectively.
Successful Global Practices to Tackle Air Pollution
