Air pollution in Indian cities is an environmental crisis that continues to dominate global headlines. India is currently ranked as the second most polluted country in the world, with particulate matter (PM2.5) posing a serious health risk to the population. According to the World Health Organization (WHO), 14 of the 20 most polluted cities in the world are in India, with Delhi, Kanpur and Varanasi consistently having hazardous air quality levels. Poor air quality not only impacts public health through respiratory illnesses and rising healthcare costs, but also threatens biodiversity and accelerates climate change.
For UPSC aspirants, air pollution is not just a social problem but a major issue that cuts across urban development, environmental policy and public administration. An understanding of India’s air pollution policies, challenges and innovative solutions is essential to pass the UPSC exam and contribute to sustainable development.
In this blog, we will examine the extent of air pollution, assess India’s current policies, discuss barriers to enforcement, offer innovative solutions and explore the role of technology and public participation in tackling pollution.
The Severity of Air Pollution in Indian Cities
Alarming Air Quality Levels
India’s largest cities are often shrouded in a toxic haze, with Air Quality Index (AQI) levels frequently exceeding the “hazardous” category of 300. New Delhi, the capital, not only has the poorest air quality among capital cities worldwide but also regularly records PM2.5 concentrations nearly ten times higher than the safe limit prescribed by the WHO. Industrial hubs like Kanpur also endure some of the worst air pollution. Beyond these well-known examples, cities like Begusarai and Guwahati have also emerged as pollution hotspots, with PM2.5 levels of 118.9 µg/m³ and 105.4 µg/m³, respectively. The Ministry of Environment has reported an alarming number of premature deaths caused by prolonged exposure to air pollution, with annual figures exceeding one million cases.

Public Health and Environmental Impact
Air pollution is among the leading causes of chronic respiratory diseases such as asthma and bronchitis. Children, the elderly, and people with preexisting health conditions bear the brunt of its consequences. Beyond health, the economic impact is staggering—air pollution costs Indian businesses approximately USD 95 billion annually, roughly 3% of India’s total GDP. This figure is equivalent to 50% of all tax collected annually or 150% of India’s healthcare budget. On top of that, healthcare costs related to air pollution in India were estimated to be nearly $12 billion in 2019. Meanwhile, reduced visibility disrupts daily life, crop yields plunge due to pollutant-induced damage, and rising greenhouse gas emissions contribute to global climate change.
Current Policies and Their Effectiveness
National Clean Air Programme (NCAP)
Launched in 2019, the NCAP aims to reduce particulate matter (PM2.5 and PM10) levels by 20-30% by 2024, using 2017 as the baseline. It targets 131 non-attainment cities that fail to meet national air quality standards, providing financial support for expanding pollution monitoring capacity, developing city action plans, and conducting public awareness campaigns. For instance, Delhi has seen declining PM2.5 levels under the Graded Response Action Plan (GRAP), but implementation issues persist in other states. Despite its ambitious goals, the NCAP’s effectiveness is hindered by a lack of inter-departmental coordination and funding gaps, raising concerns about achieving its objectives.
Bharat Stage (BS) Vehicle Standards
India’s adoption of BS-VI emission standards was a significant leap toward reducing vehicular pollution. Cleaner fuel and advanced engine technologies have aided reductions in harmful emissions, but slow penetration of electric vehicles (EVs) and inadequate charging infrastructure remain barriers.
Lessons from Global Policies
India can draw valuable lessons from China’s success in improving air quality in Beijing, where the government introduced stringent industrial regulations, shut down polluting factories, and implemented strict vehicle emission standards to tackle the severe smog problem. Similarly, London’s Low-Emission Zones, which restrict high-polluting vehicles from entering certain areas and promote the use of cleaner alternatives, have shown significant promise in curbing harmful pollutants and improving urban air quality. India is also exploring the use of AI and Machine Learning to enhance air quality forecasting and management, a move that could significantly improve the effectiveness of future policies. These examples highlight the importance of strong policy measures, modern technology, and enforcement to address environmental challenges effectively.
Challenges in Reducing Air Pollution in Indian Cities
Vehicular Pollution
Rapid urbanization and insufficient public transportation infrastructure have significantly worsened vehicular emissions in India. The growing demand for private transportation, coupled with inadequate investment in reliable public transit systems, has led to a sharp rise in private car ownership. Indian cities are now witnessing an exponential increase in the number of vehicles on the road, which contributes heavily to urban air pollution. Additionally, poor vehicle maintenance and the use of older, more polluting vehicles further intensify the issue.
Industrial Pollution
Industrial activities are one of the largest contributors to air pollution in India. Many factories and small-scale industries still operate without adequate emission controls or environmental oversight. These poorly monitored industrial zones release pollutants such as particulate matter, nitrogen oxides, and sulfur dioxide into the atmosphere, significantly deteriorating air quality. In particular, industries located near densely populated urban areas pose a dual threat by polluting both the air and the health of nearby residents.
Agricultural Practices
Stubble burning in Punjab and Haryana has a seasonal yet severe impact on air quality in north Indian cities, especially during the winter months. Despite government efforts to promote alternatives like crop residue management equipment and financial incentives, many farmers continue to burn stubble due to economic constraints and lack of awareness. Despite comprehensive policies, implementation and enforcement remain inconsistent across different states and cities. The decentralized nature of environmental governance in India leads to varied levels of compliance and effectiveness, further complicating the issue. The resulting smoke combines with existing urban pollution, creating dense smog that disrupts daily life and endangers health, particularly in cities like Delhi. This recurring issue highlights the urgent need for sustainable and affordable agricultural practices.
