Controlling Pollution In India: Strategies For A Sustainable Future

India is one of the most polluted countries in the world, with 1.4 billion people exposed to unhealthy levels of air pollution. The capital, New Delhi, is the most polluted capital city globally, with particulate matter (PM2.5) concentrations nearly 10 times higher than World Health Organization guidelines. India's rapid economic growth has been associated with this deterioration in air quality, and the effects are devastating, causing more than 2 million deaths annually and resulting in economic losses. As a result, India has launched ambitious initiatives to tackle this crisis, including the National Clean Air Program, which aims to reduce particulate matter pollution by 30% by 2024. This paragraph introduces the topic of pollution control measures in India, highlighting the severity of the problem and the country's efforts to address it.

Reducing emissions from thermal power plants, vehicles and industrial sources

India has one of the world's fastest-growing economies, but this growth has also led to a rise in air pollution. Thermal power plants, vehicles, and industrial sources are some of the main polluters, and so reducing emissions from these sources is crucial to improving air quality in India. Here are some measures that can be taken to achieve this:

Thermal Power Plants

Thermal power plants, particularly those that burn coal, are a significant contributor to India's CO2 emissions. To reduce emissions from this sector, India could adopt a carbon emission-trading system, also known as a cap-and-trade program. This system allows thermal power plants to purchase the right to emit CO2 from plants with lower abatement costs, providing a cost-effective way to achieve targeted emission levels. Additionally, India should continue its push towards renewable energy sources, as evidenced by the recent success in reducing emissions intensity by 33% over 14 years due to increased renewable energy generation.

Vehicles

Road transport is another major source of air pollution in India, with a significant impact on urban areas. To tackle this, India has implemented policies to promote the electrification of vehicles, such as the Faster Adoption and Manufacturing of Electric Vehicles (FAME) scheme. These policies aim to reduce energy demand and CO2 emissions, with electric vehicles projected to avoid up to 380 Mt CO2 by 2050. Additionally, India has introduced fuel economy standards for passenger cars and trucks, with further improvements needed to meet long-term climate goals. The scrappage policy of 2021, which requires older vehicles to pass a "fitness test", is also helping to reduce air pollution by encouraging the replacement of polluting vehicles.

Industrial Sources

Industrial emissions are a significant contributor to air pollution in India. While specific measures for each industry may vary, some general strategies include adopting cleaner technologies, improving energy efficiency, and implementing emission control technologies. Additionally, industries can explore participation in emission trading programs, which provide financial incentives for reducing emissions.

By implementing these measures, India can make significant progress in reducing emissions from thermal power plants, vehicles, and industrial sources, contributing to improved air quality and public health.

Transitioning to cleaner cooking fuels

To address this issue, India has been promoting the adoption of cleaner cooking fuels, such as liquefied petroleum gas (LPG) and piped natural gas (PNG). The Pradhan Mantri Ujjwala Yojana (PMUY) scheme, launched in 2016, aimed to provide LPG connections to rural families below the poverty line. This scheme has made a significant contribution to replacing traditional cooking fuels. Additionally, innovative payment schemes, such as the "pay-as-you-go" model, have been effective in improving access to LPG for low-income households. This model allows households to purchase credits for LPG through their phones, eliminating the burden of high upfront costs.

However, there are challenges and concerns associated with the transition to LPG and PNG. There is a risk of increased CO2 emissions, with an estimated additional 91 million metric tons of CO2 annually from LPG combustion. Moreover, LPG and PNG may not be clean enough due to associated NOx and ultrafine particle emissions, which have adverse health impacts. There is also a high reliance on imported LPG, posing energy security risks and volatile prices.

To address these challenges, alternative cleaner cooking fuels, such as electricity and biogas, can be explored. Electricity has the potential to address the shortcomings of LPG and PNG, but it has not gained popularity in India yet. Decentralization and integration of renewables in the power generation sector can provide a more sustainable solution with lower carbon intensity and stable prices. Biogas, another viable option, has been promoted through initiatives like the National Biogas and Manure Management Programme.

Overall, India's transition to cleaner cooking fuels will have global implications, offering opportunities to address multiple sustainable development goals related to health, the environment, and socio-economic development. However, it is essential to adopt a holistic approach to cooking fuel policies, considering factors such as affordability, accessibility, and supply reliability to ensure a successful transition.

Improving waste management

India is one of the world's most polluted countries, with 21 of the 30 cities with the worst air pollution. The air pollution crisis in India is multi-sectoral and multi-jurisdictional, requiring an "airshed" approach. An airshed can be defined as a region that shares a common flow of air, which may become uniformly polluted and stagnant.

To improve waste management in India, the following steps can be taken:

Firstly, there needs to be a focus on reducing waste and improving recycling practices. This can be achieved by implementing better waste segregation practices and increasing public awareness about the importance of recycling. The Indian government should also prioritize the development and implementation of waste management infrastructure, such as waste treatment facilities and landfills that meet international standards.

Secondly, India should invest in waste-to-energy technologies, which can help reduce the amount of waste sent to landfills while also generating electricity. This approach has already been successfully implemented in other countries, such as Sweden, which has a long history of converting waste into energy.

Thirdly, the Indian government should promote and incentivize the use of compostable and biodegradable products, reducing the amount of waste that ends up in landfills. This can be done through subsidies, grants, and public education campaigns.

Fourthly, the government should also focus on improving the management of construction and demolition (C&D) waste, as this is a significant contributor to air pollution in India. This includes the identification and removal of C&D waste, as well as the implementation of policies to reduce the generation of such waste.

Lastly, public participation and education are crucial. The Indian government should invest in educational campaigns to raise awareness about the importance of waste management and the negative impacts of pollution. Engaging the community will be essential to bringing about behavioral changes and encouraging people to take individual responsibility for their waste.

Implementing air quality monitoring and management initiatives

India is one of the world's most polluted countries, with 21 of the 30 cities with the worst air pollution. To address this, India has launched the National Clean Air Programme (NCAP), which aims to reduce particulate matter pollution by 30% by 2024. Implementing air quality monitoring and management initiatives is crucial to achieving this goal.

One key initiative is supporting air quality data collection and facilitating information sharing among stakeholders. This includes working with government agencies, such as the Central Pollution Control Board (CPCB), and local authorities like the Department of Environment in Delhi, to establish continuous air quality monitoring stations. These stations help identify pollution hotspots and provide data for informed decision-making.

Specific action plans are then developed to address local sources of air pollution. For example, in Delhi, 13 hotspots have been identified, including Narela, Bawana, and Mundka, which have higher air pollution levels than other areas. The action plans involve various measures, such as identifying and removing plastic and garbage dumps, repairing roads, de-congesting traffic, and closing polluting or unauthorized industries.

To ensure effective implementation, the Deputy Commissioners of Municipal Corporation of Delhi (MCD) Zones are made responsible as nodal officers for executing the action plans. Officers from other relevant departments and agencies are also included in the execution team to ensure coordinated efforts.

Additionally, community engagement is vital. Initiatives such as the Health Care Without Harm program aim to build a network of health workers who can advocate for clean air and educate patients, policymakers, and the public.

Furthermore, India is also focusing on renewable energy and electric vehicles to combat air pollution. The Delhi Metro, for instance, now meets 60% of its daytime energy requirements through solar power, reducing its dependence on coal.

By combining data collection, targeted action plans, community engagement, and a shift towards cleaner energy sources, India is working towards improving air quality and reducing the health and economic impacts of air pollution.

Encouraging the use of renewable energy and electric vehicles

India is one of the world's most polluted countries, with 21 of the 30 cities with the worst air pollution. The capital, New Delhi, has the poorest air quality of any capital city globally. To address this, India has launched the National Clean Air Programme (NCAP), which aims to reduce particulate matter pollution by 30% by 2024. A key part of this strategy is encouraging the use of renewable energy and electric vehicles (EVs).

The Indian government has set an ambitious target of 30% EV sales by 2030. To achieve this, they have introduced the Faster Adoption and Manufacturing of Electric Vehicles (FAME) program, which encourages the purchase of EVs. However, as of 2021, EVs still only account for 2% of vehicle sales in India. To increase this figure, policy interventions such as Zero Emission Vehicle (ZEV) programs could be introduced, requiring auto manufacturers to sell a certain proportion of electric vehicles. This would help to reduce air pollution and improve air quality.

One of the main barriers to the wider adoption of renewable energy is the cost of installation. Many homeowners consider solar energy too expensive, even with state and federal incentives and significant long-term savings. To encourage the use of renewable energy, the government should consider innovative market reforms to make renewable energy more affordable and attractive to consumers. For example, government subsidies for renewable energy have been reduced since 2017, which may be a factor in the slow uptake of renewable energy sources.

Another way to encourage the use of renewable energy is to highlight its advantages. Renewable energy helps to reduce climate change, as fossil fuels are the dominant contributor to CO2 emissions. In 2018, fossil fuels were responsible for 89% of CO2 emissions. By transitioning to renewable energy, India can reduce its carbon emissions and improve air quality. Additionally, the rapid growth of the solar industry is creating high-potential job opportunities, which can support local and regional economies.

Finally, the integration of renewable energy and electric vehicle charging systems can bring several benefits. For example, electric vehicle owners can sell or trade stored power, earning additional revenue. Combining a renewable energy panel system, such as solar or wind power, with an electric vehicle charging station provides a cost-effective way to produce and utilise renewable energy. This can also help to stabilise the grid by storing wind and solar power, and reduce greenhouse gas emissions.
