Indian Express: Strategies To Combat Air Pollution

Air pollution is a pressing issue in India, with 1.4 billion people exposed to unhealthy levels of ambient PM2.5, the most harmful pollutant. This has resulted in severe health consequences, including respiratory and cardiovascular illnesses, and even death. To reduce exposure to air pollution, individuals can take measures such as wearing properly-fitting masks, avoiding outdoor activities during smoggy periods, and using air purifiers indoors. Additionally, transitioning to clean energy sources, such as renewable energy and electric vehicles, is crucial. The Indian government has also implemented various initiatives, such as the National Clean Air Programme (NCAP), to combat air pollution and improve air quality across the country.

Wear properly-fitting masks to reduce exposure to air pollution

Wearing a mask is an effective way to protect yourself from air pollution. However, not all masks are created equal, and it is important to choose one that offers sufficient protection.

N95 masks are a type of respirator that can filter out up to 95% of airborne particles. They are designed to fit tightly against the face, leaving almost no gaps, and use a denser filtering material than surgical masks. This makes them more effective at protecting against small particles and germs. However, they can be uncomfortable to wear for extended periods and are more expensive than surgical masks.

Surgical masks, on the other hand, are looser-fitting and designed to stop water droplets. While they can provide some protection against larger particles, they are less effective against small, lightweight particles due to the gaps between the skin and the edges of the mask. They are ideal for settings with airborne pathogens, such as hospitals, as they prevent viruses and bacteria from leaving the wearer's body through bodily fluids.

When wearing a mask, it is important to ensure a proper fit to maximise protection. This includes placing the mask over the nose and mouth, using the metal strap to form a seal around the nose, and adjusting the metal strip to conform to the shape of the nose for a secure fit.

Additionally, it is crucial to practise good mask hygiene. Reusable masks should be washed daily, and it is recommended to have multiple masks to rotate between. Used disposable masks should be discarded in a closed bin, and hands should be washed or sanitised after touching them.

While masks can provide protection against air pollution, the best way to stay safe is to stay indoors when the air quality is poor. Keeping windows and doors shut and using an air conditioner, if possible, can help reduce exposure to outdoor pollutants.

Transition to renewable energy sources

India's transition to renewable energy sources is a critical component of its efforts to reduce air pollution. The country has set ambitious targets, including reaching net-zero emissions by 2070 and meeting 50% of its electricity requirements from renewable sources by 2030. This shift towards clean energy is already well underway, with India overachieving its commitments from the Paris Summit by meeting 40% of its power capacity from non-fossil fuels ahead of schedule.

The Indian government has recognised that a transition to clean energy is a huge economic opportunity. The country is well-positioned to become a global leader in renewable batteries and green hydrogen, with the potential to create a market worth up to $80 billion by 2030. Additionally, India has set ambitious targets for electric vehicle (EV) sales penetration by 2030: 30% for private cars, 70% for commercial vehicles, and 80% for two- and three-wheelers.

The energy sector in India is undergoing a profound transformation, moving away from fossil fuels and embracing renewable energy sources. Within the renewables sector, solar power accounts for the biggest share at 53.4%, followed by wind power at 34.1%. The government has also launched initiatives to promote the adoption of electric vehicles, such as providing subsidies and installing charging infrastructure across the country.

To further accelerate the transition to renewable energy, the Indian government has implemented several policy measures. These include removing subsidies for petrol and diesel in the early 2010s and introducing subsidies for electric vehicles in 2019. Additionally, India has a robust energy efficiency programme that has successfully reduced energy use and emissions from buildings, transport, and major industries.

The benefits of transitioning to renewable energy sources are significant. Renewable energy sources do not produce any air pollution when generating electricity, in contrast to fossil fuels, which release harmful pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter. By scaling up renewable energy and promoting electric vehicles, India can improve air quality, protect human health, and build a more sustainable future.

However, there are challenges to scaling up renewable energy in India. One of the biggest challenges is the high cost of solar and wind power plants. Another challenge is the need to develop a strong grid infrastructure to support renewable energy integration, as renewable sources are intermittent and can be challenging to integrate into the grid. Nonetheless, the cost of renewable energy has been falling, and technological developments and a vibrant private sector have made solar power plants cheaper to build than coal-based ones.

In conclusion, India's transition to renewable energy sources is a critical component of its strategy to reduce air pollution. The country has set ambitious targets and is already making significant progress. The transition to clean energy offers economic opportunities and the potential to improve air quality and protect human health. By addressing the challenges and continuing to implement supportive policies, India can accelerate its progress towards a sustainable and renewable energy future.

Stop the use of coal in hotels and restaurants

According to an IIT Kanpur study, there are approximately 9,000 hotels and restaurants in Delhi that use coal, mostly in tandoors. They are a major source of PM emissions in the form of fly ash, a byproduct of coal combustion that can cause lung disease if inhaled.

To reduce air pollution, the report suggests that each household should avoid using wood, crop residue, cow dung, and coal for cooking. Instead, everyone should get access to Liquefied Petroleum Gas (LPG), which would bring down levels of PM 2.5, PM 10, and nitrogen oxides (NOx).

Provide Alternatives to Coal for Cooking

The government and private sector should work together to provide alternative sources of fuel for cooking, such as LPG cylinders. This will not only reduce air pollution but also provide a safer and more efficient source of energy for households and businesses.

Create Awareness Campaigns

Conduct awareness campaigns to educate the public about the harmful effects of coal combustion on human health and the environment. Emphasize the long-term benefits of switching to cleaner sources of energy, such as reduced air pollution, improved respiratory health, and a reduced carbon footprint.

Implement Policies and Regulations

The government should implement policies and regulations to discourage the use of coal in hotels and restaurants. This could include incentives for businesses to switch to alternative sources of energy, such as subsidies or tax breaks. Additionally, strict emission standards and penalties for non-compliance should be enforced to ensure businesses transition away from coal.

Promote the Use of Electric or Hybrid Vehicles

The IIT Kanpur report also suggests promoting the use of electric, hybrid, and BS-VI vehicles to reduce air pollution. Hotels and restaurants can contribute to this by investing in electric or hybrid vehicles for their own operations, such as food delivery or transportation services.

Support Renewable Energy Sources

Invest in and promote the use of renewable energy sources, such as solar, wind, or hydroelectric power. This can be done through government initiatives, such as providing subsidies or grants for businesses to install renewable energy systems. Additionally, encourage hotels and restaurants to use energy-efficient appliances and practices to reduce their overall energy consumption.

By implementing these measures, India can significantly reduce its reliance on coal, improve air quality, and protect the health and well-being of its citizens. It is important to remember that a combination of these strategies, along with coordinated and sustained actions across various sectors, will be most effective in tackling the air pollution crisis.
