India's Pollution: A Global Concern?

India's poor air quality is a well-known issue, with the country ranking 5th in the world for air pollution. The air pollution in India has been attributed to various factors, including traffic, fossil fuel-burning power plants, heavy industries, and the burning of organic materials for cooking and heating in rural areas. This pollution has severe consequences for the health and economy of India, reducing life expectancy and causing diseases that further impact productivity and labour supply. With India's pollution levels affecting over 1.3 billion people, it is a pressing issue that requires state-specific control strategies and better access to air quality data to implement effective solutions. Given the global nature of pollution, it is essential to consider whether India's pollution extends beyond its borders and impacts other regions.

India's air pollution policies

India's air pollution is a serious environmental issue, with 21 of the world's 30 most polluted cities in 2019. The country's rapid economic growth and development have contributed to this crisis. The main sources of India's particulate air pollution include industrial and vehicular emissions, construction dust, waste burning, and the use of wood and dung for cooking and heating. In addition, the country's dependence on thermal power for electricity and unsanctioned tyre pyrolysis plants significantly impact air quality. These factors have led to a public health emergency, with an estimated 300,000 to 400,000 people dying from indoor air pollution and carbon monoxide poisoning annually.

To address this crisis, the Indian government has implemented several policies and regulations. The National Clean Air Programme (NCAP), launched in 2019, aims to improve air quality in over 100 of India's most polluted cities. The programme provides a framework for cities to develop air quality management plans and sets a time-bound goal for improving air quality, focusing on 132 "non-attainment" cities. However, NCAP has faced criticism for its poor design and underfunding, and the challenge of reducing pollution within city boundaries while being unable to control external emissions.

Other policies include emission standards for industries and vehicles, such as the Bharat Stage VI standards, and restrictions on crop burning. India has also developed policies promoting cleaner fuels, renewable energy sources, and energy-efficient housing. Several cities have successfully implemented initiatives like cleaner fuel standards, public transportation promotion, and air quality monitoring systems.

The World Bank and the Clean Air Fund are aiding India in Air Quality Management through phased strategies, knowledge enhancement, stakeholder involvement, and policy analysis. These organisations work with the government, businesses, and the public to achieve India's clean air goals.

While India has initiated various measures, the complexity and pervasiveness of the air pollution problem require urgent and coordinated efforts from all sectors. Effective policies, clean technologies, public awareness, and a culture of sustainability are crucial to mitigating adverse health and environmental impacts and achieving a cleaner future for India's citizens.

The health impact of India's pollution

India is the world's second most polluted country, with 1.3 billion people living in areas where the annual average particulate pollution level exceeds the World Health Organization (WHO) guideline. India's pollution has a significant impact on the health of its citizens, reducing their life expectancy and causing various diseases and premature deaths.

Health Impact of India's Pollution

Fine particulate air pollution (PM2.5) shortens an average Indian's life expectancy by 5.3 years, with some areas faring much worse. In the National Capital Territory of Delhi, the most polluted city in the world, air pollution shortens lives by 11.9 years. The Northern Plains, the most polluted region of the country, is home to 521.2 million people who are on track to lose 8 years of life expectancy relative to the WHO guideline.

The high levels of pollution in India have been linked to an increased risk of various diseases, including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases, and respiratory infections such as pneumonia. In 2019, an estimated 1.67 million deaths in India were attributable to air pollution, accounting for 17.8% of the total deaths in the country. The economic cost of these premature deaths and the associated morbidity is substantial, with India incurring losses of $36.8 billion in 2019, equivalent to 1.36% of its gross domestic product (GDP).

The Indian government has recognized the severity of the problem and has implemented various measures to improve air quality. These include the National Clean Air Programme (NCAP), which aims to improve air quality across the country, with a focus on 132 cities that are not meeting air pollution standards. India is also expanding renewable energy, promoting electric vehicles, and supplying LPG cooking fuel to households to reduce emissions. Additionally, organizations like the Clean Air Fund are working with the government and businesses to help India achieve its clean air goals.

While India's efforts to combat pollution are commendable, the country still has a long way to go in reducing the health and economic impacts of air pollution. Successful reduction of air pollution through state-specific strategies will be crucial in improving the health and well-being of India's population.

India's pollution compared to other countries

India is one of the world's most polluted countries, with 21 of the world's 30 cities with the worst air pollution. The capital, New Delhi, has the poorest air quality among capital cities globally. Concentrations of particulate matter (PM2.5) in New Delhi are nearly 10 times higher than the World Health Organization guidelines. Thermal power plants, vehicle pollution, industrial emissions, and the burning of wood and dirty fuels for cooking and heating are some of the main causes of air pollution in India.

From 2013 to 2021, 59.1% of the world's increase in pollution was attributable to India. In 2024, 74 of the 100 most polluted cities and towns were in India, according to the World Air Quality Report. Despite this, India's expansive air quality monitoring network has brought down its national average compared to other heavily polluted countries.

The impact of India's pollution is not limited to its borders. Air pollution knows no borders, and the emissions from India can contribute to the overall global pollution levels, affecting other countries. Additionally, India's pollution has economic implications beyond its borders. For example, if India had achieved safe air quality levels in 2019, its GDP would have increased by $95 billion due to increased productivity, consumer activity, and reduced premature deaths.

While India's pollution levels are concerning, it is encouraging to see that the country is taking steps to address the issue. India has launched the National Clean Air Program, aiming to reduce particulate matter pollution by 30% by 2024. The Indian Institute of Technology Kanpur is collaborating with relevant departments and organizations to implement real-time measures to mitigate pollution sources. Additionally, the World Bank is introducing tools to support state and regional air quality management approaches in India. These efforts demonstrate India's commitment to tackling its pollution problem and improving the health and well-being of its citizens.

India's pollution control initiatives

India is one of the most polluted countries in the world, with 100% of its 1.4 billion population exposed to unhealthy levels of ambient PM2.5, the most dangerous type of air pollutant. Air pollution poses a major health risk, causing heart and lung diseases and cancer, and it also translates into economic losses, with air pollution offsetting nearly 1.36% of India's GDP in 2019 and costing its economy 4.5% in 2022.

To tackle this crisis, India has implemented various pollution control initiatives. One example is the National Clean Air Program (NCAP), launched in January 2019, with the goal of reducing pollution levels in 102 of the most polluted cities by 20-30% in five years. The NCAP focuses on the Indo-Gangetic Plain, where population density and pollution intensity are the highest. The World Bank program introduces tools to support state and regional air quality management, helping formulate India's first State Air Quality Action Plans and Regional Airshed Action Plan for the Indo-Gangetic Plains (IGP).

Another initiative is the use of bio-decomposers to combat stubble burning, a significant contributor to winter pollution. India is also exploring dynamic toll pricing on highways and bridges based on real-time air quality data to regulate traffic flow and reduce emissions during high-pollution days. Additionally, the Building Healthy Cities Project, funded by USAID, trained local volunteers as clean air guides in Indore, India. These guides educated the community, organized advocacy efforts, and maintained and read air sensor data.

The private sector also plays a crucial role in combating air pollution. The Confederation of Indian Industry's CEO Forum for Clean Air brings together business leaders to catalyse cross-sector change. India is also creating opportunities for cutting-edge environmental technologies to address its persistent air and water pollution problems. The market for environmental technologies in India is expected to grow significantly, with a focus on air pollution control, solid waste and recycling, and water/wastewater management.

Furthermore, India could benefit from adapting urban planning strategies that prioritise green spaces, similar to those implemented in Curitiba, Brazil. These initiatives demonstrate India's commitment to addressing its air pollution crisis and mitigating its impact on public health and the economy.

The economic impact of India's pollution

India is the world's second most polluted country, with 100% of its population exposed to unhealthy levels of ambient PM2.5. This is one of the most harmful pollutants, causing deadly illnesses such as lung cancer, stroke, and heart disease. As a result, India's pollution has had a significant economic impact on the country.

Firstly, India's pollution has resulted in a substantial loss of output and productivity. In 2019, lost output from premature deaths and morbidity attributable to air pollution accounted for economic losses of up to US$36.8 billion, which was approximately 1.36% of India's gross domestic product (GDP). The economic loss as a proportion of state GDP varied across the states, with the highest loss occurring in low per-capita GDP states such as Uttar Pradesh, Bihar, Rajasthan, Madhya Pradesh, and Chhattisgarh. Delhi, the country's most polluted city, had the highest per capita economic loss due to air pollution. This loss of output could hinder India's aspiration to become a $5 trillion economy by 2024.

Secondly, India's pollution has led to increased healthcare costs and burdens on the healthcare system. The India State-Level Disease Burden Initiative has found that exposure to air pollution is associated with increased disease burden and mortality. For example, the death rate due to ambient particulate matter pollution increased by 115.3% from 1990 to 2019, while the rate due to ambient ozone pollution increased by 139.2%. These adverse health outcomes have direct and indirect economic costs, including medical expenses, lost workdays, and reduced productivity.

Thirdly, India's pollution has impacted the country's ability to attract foreign investment and develop its economy. As pollution levels rise, businesses may choose to invest in other countries with cleaner environments and better air quality. Additionally, pollution can hinder economic growth by reducing worker productivity, increasing healthcare costs for businesses, and limiting the potential for innovation and development.

Finally, India's pollution has resulted in the implementation of costly pollution control measures and policies. The Indian government has launched the National Clean Air Program (NCAP) to reduce particulate matter pollution by 30% by 2024. While this program is necessary to improve air quality, it requires significant funding and resources, impacting the country's economic development. Additionally, individual states and cities incur costs associated with monitoring, enforcement, and compliance with air quality standards.

Overall, India's pollution has had a significant economic impact on the country, resulting in lost output, increased healthcare costs, reduced foreign investment, and the implementation of costly pollution control measures. Addressing India's pollution problem is crucial not only for the health and well-being of its citizens but also for the country's economic growth and development.
