Reducing Air Pollution In India: Strategies For A Cleaner Future

India has been struggling with air pollution for decades, and it poses a grave risk to the country's development goals. The economic cost of air pollution to the Indian economy is estimated at more than $150 billion annually, and it is one of the top health risk factors in the country. While the Indian government has launched several initiatives to combat air pollution, such as the National Clean Air Programme (NCAP), these policies have often been ineffective due to underfunding and poor design. However, there is a growing understanding that solving air pollution in India can boost the economy and business, and improve public health. This includes increasing consumer spending, reducing sick leaves, and improving employee productivity. To achieve these goals, India needs to implement comprehensive policies, invest in specialized workforces, increase citizen engagement, and address the root causes of air pollution, such as emissions from vehicles and industries.

Improve public transport to discourage private vehicle usage

India's air pollution problem is a pressing issue, with the country facing economic and health consequences if it fails to address it. Air pollution in India costs its economy an estimated $95 billion per year, and it is the second-largest risk factor contributing to the country's disease burden. To combat this, India has implemented various policies and initiatives, including the National Clean Air Programme (NCAP), which aims to reduce key air pollutants by 20-30% by 2024.

One of the strategies to reduce air pollution in India is to improve public transportation to discourage private vehicle usage. Here are some ways to do this:

Increase investment in public transport infrastructure

The Indian government should allocate more funds to develop and improve public transport systems such as the Metro, overhead rail, and bus services. This includes investing in clean technologies, such as electric vehicles and renewable energy sources, to reduce emissions from the transportation sector.

Make public transport more affordable and accessible

By subsidizing fares or offering discounted rates for frequent users, the government can encourage more people to use public transportation. This can be especially beneficial for low-income communities who may otherwise rely on private vehicles due to financial constraints. Making public transport more affordable increases its usage, reducing the number of private vehicles on the road and, consequently, their emissions.

Enhance safety and convenience

Ensuring that public transport is a safe and convenient option for commuters is crucial in encouraging its usage. This involves implementing measures such as increasing the frequency of services, improving lighting and security at stations and stops, and providing real-time arrival and departure information to reduce waiting times.

Promote integrated transport systems

Developing integrated transport systems that allow for seamless transfers between different modes of public transportation can make it more attractive to commuters. For example, providing park-and-ride facilities at Metro stations, where people can park their cars and complete their journey using the Metro, can reduce private vehicle usage.

Encourage behavioral change

Public awareness campaigns can play a vital role in encouraging people to choose public transportation over private vehicles. Highlighting the environmental and health benefits of reduced air pollution, as well as the potential for improved productivity and reduced traffic congestion, can help shift public perception and encourage a cultural shift toward public transport usage.

Improving public transportation to discourage private vehicle usage is a crucial step in reducing air pollution in India. By implementing these strategies, India can make significant progress toward creating a greener, healthier, and more sustainable future for its citizens.

Implement car-pooling and bicycle lanes

India's air pollution problem poses a grave risk to the country's development goals, causing a rapid increase in public health expenditure, diminished labour productivity, and reduced agricultural yields. It is estimated to cost the Indian economy over $95 billion per year. As such, implementing car-pooling and bicycle lanes can be an effective strategy to reduce air pollution in India, particularly in highly congested cities like Delhi.

One way to encourage car-pooling is through the creation of high-occupancy toll (HOT) lanes, or HOV lanes. This involves dedicating specific lanes on roads and highways to cars carrying more than one occupant, typically three or more. This strategy has been successfully implemented in other countries, such as the US, China, and Indonesia, leading to a significant increase in car-sharing. To incentivize commuters to use these lanes, tolls could be completely exempted or substantially reduced compared to other lanes. Implementing HOT lanes can also foster a more disciplined driving culture and help reduce traffic congestion.

In addition to HOT lanes, the Indian government and local authorities have promoted various car-pooling initiatives. For example, in Bengaluru, the Traffic Police and Karnataka State Pollution Control Board endorsed "Let's Drive Along," a carpool app. Similarly, in Kolkata, the Police Department and IIT Kharagpur are working with the Pool Car Operators Welfare Association to promote carpooling in areas not served by buses. The Delhi government has also launched carpool platforms, such as the Poochh-O Carpool app, and existing platforms like BlaBlaCar and Orahi have gained popularity during vehicle rationing schemes. However, the legality of carpooling models remains a grey area, and there are concerns about the blurring lines between private and commercial services.

Implementing bicycle lanes in residential areas and on roads in cities like Delhi can also help reduce air pollution and encourage safe travel by bicycles. This measure can reduce traffic-based air pollution and congestion, providing a sustainable and environmentally friendly mode of transportation for shorter distances.

By combining the implementation of car-pooling initiatives and dedicated lanes with the development of bicycle lanes, India can take significant steps towards reducing air pollution, improving public health, and mitigating the economic impacts of poor air quality.

Encourage cleaner fuel sources

India is the world's second most populous country and the third-largest economy, and it is rapidly growing. The country has been working to provide modern energy products and services to millions of households living in energy poverty. However, India's air quality has significantly deteriorated over the past two decades, and air pollution poses a grave threat to the country's development goals. It leads to increased public health expenditure, reduced labour productivity, and lower agricultural yields, costing the Indian economy an estimated $95 billion per year.

To reduce air pollution and encourage cleaner fuel sources, India can take several measures:

• Promote the use of Compressed Natural Gas (CNG) vehicles: CNG is a much cleaner fuel alternative to petrol or diesel. By offering tax incentives for CNG-filled cars and making all new car registrations CNG-only, India can encourage a shift towards cleaner fuel sources.
• Encourage the adoption of liquefied petroleum gas (LPG): LPG is a clean-burning fossil fuel that reduces indoor air pollution, especially in rural households where traditional cooking fuels like solid biomass are still commonly used. The Pradhan Mantri Ujjwala Yojana (PMUY) scheme, which provides free LPG connections to poor households, has accelerated the adoption of LPG. Social networks also play a crucial role in encouraging households to switch to LPG.
• Support the development and adoption of renewable energy sources: India can provide subsidies and incentives for renewable energy sources such as solar power, especially in unelectrified areas. This will help reduce the country's reliance on fossil fuels and decrease indoor air pollution caused by kerosene use.
• Invest in clean technologies: India needs to invest in cleantech to save lives and livelihoods. This includes supporting the development and adoption of electric vehicles, improving fuel efficiency in existing vehicles, and encouraging public transportation.
• Implement the National Clean Air Programme (NCAP) effectively: The NCAP aims to reduce key air pollutants by 20-30% by 2024. However, it has struggled to enforce its targets due to a lack of legal mandate. Providing adequate financial support and legal enforcement to the NCAP can help India make significant progress in reducing air pollution.

By encouraging cleaner fuel sources and implementing effective policies, India can improve its air quality, reduce its economic losses, and enhance the health and well-being of its citizens.

Invest in cleantech and pollution control

India has been taking significant steps to address its air pollution crisis, which poses a grave risk to the country's development goals, public health, and economy. One of the key strategies is to invest in cleantech and pollution control, which involves implementing innovative solutions and technologies to reduce emissions and improve air quality.

The Indian government has demonstrated a strong commitment to addressing air pollution by increasing funding for pollution control initiatives. In the 2019-2020 budget, the allocation for pollution control was increased almost tenfold, from US$678,000 to US$62.2 million. This trend continued in the 2020-2021 budget, with a further increase to US$63.01 million. These funds are crucial for supporting local and national initiatives aimed at reducing air pollution.

One notable initiative is the National Clean Air Programme (NCAP), which was launched in 2019. The NCAP calls on 122 cities across India to develop and implement city-level Clean Air Plans to reduce ambient PM10 and PM2.5 concentrations. The programme sets a target of a 20-30% reduction in these key air pollutants by 2024. However, the NCAP has faced challenges in legally enforcing its targets, highlighting the need for stronger policy measures and mandates.

To effectively tackle air pollution, India is also focusing on renewable energy and electric vehicles. The Delhi Metro, for example, is now powered by solar energy, reducing its dependence on coal and saving millions in energy costs. Additionally, India is promoting the use of LPG cooking fuel and encouraging the adoption of electric vehicles to reduce vehicular emissions.

The private sector also has a crucial role to play in investing in cleantech and pollution control. Businesses can benefit from improved air quality through increased consumer spending and improved employee health and productivity. A report by the Clean Air Fund and Dalberg Advisors highlights the economic benefits of reducing air pollution, including higher revenues for businesses and increased economic growth.

Overall, investing in cleantech and pollution control is essential for India to address its air quality crisis and unlock the social and economic benefits of a cleaner, healthier environment. By collaborating with local communities, governments, and businesses, India can develop and implement effective solutions to reduce air pollution and improve the lives of its citizens.

Strengthen air quality management strategies and enforcement

Strengthening air quality management strategies and enforcement is key to reducing air pollution in India. Here are several measures that can be implemented to achieve this:

• Enhance monitoring and enforcement capabilities: India has made progress in monitoring air quality, but consistent and rigorous monitoring, as well as reporting, are essential. This includes investing in advanced pollution forecasting technologies and developing a system to integrate live emissions data with data on pollution sources. This system should provide real-time analysis and targeted recommendations for emergency measures. For instance, if high pollution levels are predicted, the system could recommend limiting traffic or temporarily halting construction activities.
• Strengthen local and regional capacities: Local and regional governments play a crucial role in implementing effective air quality management strategies. It is important to empower them with the necessary resources and authority to develop and enforce policies that address their specific pollution challenges. This includes providing financial assistance to pollution control boards and committees, as well as ensuring that grants allocated for pollution reduction projects are utilized effectively and maximize air pollution reductions.
• Comprehensive policy interventions: Governments should develop comprehensive policies that target the various sources of air pollution, including industry, transportation, and road traffic. This includes enforcing stricter emission standards for vehicles, power plants, and industries, as well as promoting cleaner energy sources and processes. For instance, the Bharat Stage VI emission standards, implemented in 2020, represent one of India's most ambitious efforts, targeting tailpipe emissions from a wide range of vehicles.
• Legal mandate for action plans: While India has launched initiatives like the National Clean Air Programme (NCAP), they often lack legal enforceability. To make such action plans effective, they need to be backed by legislation that sets clear targets for pollution reduction and holds responsible parties accountable. This includes setting enforceable standards for emissions, air quality, and pollution control measures, with penalties for non-compliance.
• Increase collaboration and citizen engagement: Reducing air pollution requires collaboration between governments, businesses, and citizens. Citizens should be encouraged to take initiatives like carpooling, using public transportation, or switching to cleaner fuel options. Additionally, raising awareness about the health and economic impacts of air pollution can help build public support for stronger enforcement of pollution control measures.
