Strategies To Reduce Pollution In India

India is facing a grave air pollution crisis, with 14 of the 20 most-polluted cities in the world located in the country. The air quality in India has deteriorated significantly over the past two decades, and it is now the second-largest risk factor contributing to the country's disease burden.

The Indian government has implemented various policies and programs to address this issue, such as the National Clean Air Programme (NCAP), which aims to reduce key air pollutants by 20-30% by 2024. However, the success of these measures has been limited due to a lack of legal enforcement and data-related implementation issues.

To effectively reduce pollution in India, a combination of strategies is necessary. This includes the use of public transportation, recycling and reusing products, reducing forest fires and smoking, implementing afforestation initiatives, and reducing emissions from thermal power plants and vehicles. Strong leadership and ambitious actions at the city level are crucial for delivering lasting improvements in public health and the environment.

Improving public transport to reduce vehicle emissions

India is facing a public transport crisis, with a rapid increase in the number of private vehicles on the roads. This has led to a rise in emissions and air pollution, which has severe consequences for the environment and public health. To reduce vehicle emissions, India should focus on improving its public transport systems.

Firstly, investment in new buses and technology upgrades is essential. Many public bus corporations are operating at a financial loss and are unable to invest in new, more fuel-efficient vehicles. The Indian government should provide support and subsidies to ensure these corporations can modernise their fleets and reduce their environmental impact. Improving fuel efficiency in buses will not only benefit the environment but also improve the financial viability of bus companies, as fuel accounts for 30% of their expenses.

Secondly, India should promote and incentivise the use of public transport. Taking public transportation reduces CO2 emissions by 45% compared to driving private cars. This will not only improve air quality but also lead to healthier communities, with fewer cases of respiratory issues and other health problems. To encourage people to choose public transport, measures such as preferential parking, low-emission zones, and stringent fuel economy standards can be implemented.

Additionally, India should continue its efforts to electrify its transport sector. Electric vehicles (EVs) have the potential to significantly reduce emissions and citizens' exposure to air pollution. While India's EV market is growing, high upfront costs can deter consumers. The government should continue to address this through initiatives like the Faster Adoption and Manufacturing of Electric Vehicles (FAME) scheme, which provides purchase incentives and charging infrastructure support.

Furthermore, improving fuel efficiency in conventional vehicles is crucial. India has implemented fuel economy standards for passenger cars, and similar regulations for trucks are expected by the end of 2023. These standards should be regularly updated and gradually tightened to achieve greater emissions reductions. Additionally, incentives and infrastructure development for zero-emission vehicles (ZEVs) can accelerate their deployment and further reduce vehicle emissions.

By implementing these measures, India can improve its public transport systems, reduce vehicle emissions, and contribute to a cleaner and healthier environment for its citizens.

Reducing the use of loudspeakers and horns to limit noise pollution

Noise pollution is a serious issue in India, with cities experiencing rapid growth and some of the noisiest roads in the world. This type of pollution is caused by various sources, including vehicles honking, construction activities, and loudspeakers. It has detrimental effects on both physical and mental health, leading to issues such as respiratory agitation, high blood pressure, migraines, depression, anxiety, and insomnia.

To address this problem, several measures can be implemented:

• Public Awareness and Education: Raising awareness about the harmful effects of noise pollution is essential. People should understand the impact of noise on their health and well-being. Educational campaigns can promote the importance of reducing noise levels, especially in sensitive areas like residential neighborhoods and silence zones.
• Enforce Existing Rules and Regulations: India already has noise pollution rules and regulations in place, such as the Noise Pollution Rules, Supreme Court and High Court orders, which restrict decibel levels and the use of horns in specific areas. Effective enforcement of these rules is crucial to reducing noise pollution.
• Modify Horn and Silencer Use: The use of pressure horns and modified silencers, which contribute significantly to noise levels, should be strictly regulated and penalized. This includes enforcing limits on the decibel levels of horns and ensuring that vehicles comply with noise standards during the manufacturing stage.
• Implement Innovative Solutions: Acoustic cameras, similar to speed trapping cameras, can be installed to identify noise violations and impose fines. Additionally, exploring the use of electric vehicles, which are silent at low speeds, can help reduce noise levels, especially in urban areas.
• Vegetation and Noise Barriers: Strategic placement of vegetation and the implementation of noise barriers or sound walls can help reduce noise levels in specific areas. Vegetation acts as a natural noise attenuator, while noise barriers are effective in blocking high-intensity traffic noise.
• Reduce Vehicle Speeds: Slower vehicle speeds can contribute to reduced noise levels. Implementing speed-reduction infrastructure changes and enforcing speed limits can help achieve this.
• Promote Alternative Transportation: Encouraging the use of bicycles or electric vehicles instead of cars can help decrease road noise. This can be achieved through initiatives like bike-sharing programs and the development of dedicated bike lanes.
• Noise-Absorbing Materials: The use of noise-absorbing materials in building construction can help reduce indoor noise levels, creating quieter living and working spaces.

By implementing these measures, India can effectively reduce noise pollution caused by loudspeakers and horns, improving the health and well-being of its citizens and creating a more peaceful environment.

Implementing eco-friendly waste disposal methods

India's rapidly growing economy has resulted in a significant amount of waste, which has so far been poorly managed. Implementing eco-friendly waste disposal methods is crucial to reducing pollution and its harmful effects on the environment and human health. Here are some detailed suggestions for India to adopt more sustainable waste disposal practices:

Segregating Waste

A fundamental step towards eco-friendly waste disposal is proper waste segregation. Recyclable materials should be separated from non-recyclable waste to facilitate efficient recycling and reduce landfill waste. This includes separating materials such as paper, plastic, glass, and metal for recycling. Additionally, hazardous waste, like electronics, chemicals, and batteries, must be kept separate from general waste to ensure safe disposal and prevent further environmental damage.

Reusing and Recycling Materials

Reusing and recycling waste is essential to reducing the amount of waste generated. Construction sites, for example, can recycle and reuse materials such as wood, metal, concrete, and glass. Old timber can be re-milled into new flooring or panelling, while metal scraps can be melted down and reformed into new products. Recycling e-waste is particularly important due to the presence of hazardous substances and the potential for valuable material recovery. Proper e-waste recycling involves dismantling electronics to recover materials like plastics, metals, and circuit boards, which contain precious metals.

Composting Organic Waste

Organic waste from kitchens and yards can be effectively managed through composting. Compost piles can be easily created in small spaces, using methods like worm composting and bokashi buckets. Composting reduces landfill waste and produces nutrient-rich fertiliser for gardens and farms.

Generating Energy from Waste

Anaerobic digestion plants can convert waste that rots into biogas and fertiliser, providing a source of clean energy and reducing the need for landfill. This approach has been successfully implemented in Sweden, where 100% of garbage is converted into energy, with additional waste imported from other countries for this purpose.

Adopting Sustainable Practices

To further reduce waste and pollution, individuals and industries should adopt sustainable practices. This includes reducing the use of single-use plastics and other materials, extending the lifespan of electronic devices through maintenance, and choosing to buy from brands with strong Extended Producer Responsibility (EPR) policies. EPR policies ensure that companies take responsibility for the proper disposal and recycling of their products.

By implementing these eco-friendly waste disposal methods, India can significantly reduce pollution, conserve natural resources, and protect public health and the environment.
