Causes of low pollution
India's pollution problem is a serious environmental issue, with 84 of the world's 100 most polluted cities located in the country. However, some Indian cities have lower pollution levels than others. Here are the causes of low pollution in these cities:
Geographical Location and Natural Surroundings:
Aizawl, the capital of Mizoram, is located over 1,100 meters above sea level. Its elevation, thick greenery, and natural airflow contribute to cleaner air. Similarly, Koppal in Karnataka is surrounded by hills and farmlands, while Raichur benefits from its natural landscapes, keeping pollution levels low.
Low Industrial Activity and Fewer Factories:
Gadag in Karnataka stands out for its low industrial activity, minimal pollution sources, and open spaces. Aizawl also has fewer factories, contributing to its cleaner air.
Less Traffic and Efficient Traffic Management:
Cities with less traffic congestion, such as Aizawl and Koppal, tend to have lower pollution levels. Efficient traffic management and well-designed road infrastructure can help reduce traffic congestion and, consequently, air pollution.
Government Initiatives and Policies:
The Indian government has taken steps to address air pollution, such as launching the National Clean Air Programme in 2019, targeting a 20-30% reduction in PM2.5 and PM10 concentrations by 2024. Additionally, the Commission for Air Quality Management has implemented the Graded Response Action Plan (GRAP) to combat pollution during severe air quality episodes.
Community Efforts and Awareness:
In some cases, local communities and authorities have worked together to improve air quality. For example, the river Thames, once considered biologically dead, was brought back to life through collective efforts, and similar initiatives can inspire action in Indian cities.

Efforts to promote clean air
India is one of the world's most polluted countries, with 17 of the world's 30 most air-polluted cities. The country's capital, New Delhi, has the poorest air quality among capital cities globally, with particulate matter (PM2.5) concentrations nearly 10 times higher than World Health Organization guidelines. The main sources of air pollution in India include thermal power plants, vehicle emissions, industrial emissions, crop residue burning, and the burning of wood and dirty fuels for cooking and heating.
To tackle this issue, India has undertaken several efforts to promote clean air and improve air quality. Here are some key initiatives:
National Clean Air Programme (NCAP)
The Indian government has introduced the National Clean Air Programme (NCAP), a comprehensive framework to tackle deteriorating air quality. The NCAP focuses on 132 cities that fail to meet air pollution standards, providing a flexible framework for cities to develop air quality management plans and encouraging collaboration across jurisdictions.
Graded Response Action Plan (GRAP)
Many cities in India have implemented the Graded Response Action Plan (GRAP) to address poor air quality. Stage I of GRAP includes measures such as dust mitigation at construction sites, effective waste management, and regular road cleaning. These steps are particularly crucial during winter months when pollution levels surge due to agricultural burning, vehicle emissions, and industrial output.
Collaboration with Organizations
India has collaborated with organizations like the Clean Air Fund to achieve its clean air goals. The Fund supports the government by improving air quality data, providing technical assistance to sub-national governments, and facilitating dialogue between stakeholders like private sector leaders and healthcare practitioners. The Indian Institute of Technology Kanpur (IIT-K) is also working with various government departments to enhance air quality data, monitoring, and source apportionment.
Business Engagement
The Confederation of Indian Industry has developed a Corporate Air Emissions Reporting Guide to assist businesses in managing and reporting their air emissions. The India CEO Forum for Clean Air, with over 130 members, aims to galvanize the private sector to address poor air quality. The Clean Air Fund has also empowered healthcare professionals to amplify the health impacts of air pollution.
Building Healthy Cities Project
In Indore, India, the Building Healthy Cities Project, funded by USAID, trained local volunteers as clean air guides. These guides educated the community, maintained and read air sensor data, and supported advocacy efforts for cleaner air.
Technological Innovations
Chennai-based startup Thales Cleantech has innovated by developing a method to extract potable water from the air with zero carbon emissions. Additionally, advancements in satellite technology have improved air quality monitoring and enhanced our understanding of environmental challenges.
Emphasis on Renewable Energy and Electric Vehicles
The Indian government is emphasizing the expansion of renewable energy sources and the promotion of electric vehicles. This shift aims to reduce vehicle and industrial emissions, which are significant contributors to air pollution in the country.
These efforts demonstrate India's commitment to addressing air pollution and improving the health and well-being of its citizens. By embracing collaboration, innovation, and sustainable practices, India is working towards creating a cleaner and healthier future for its populace.

Healthiest cities in India
India is facing critical environmental challenges due to poor air quality, with significant variations across different cities. However, some cities have cleaner air and healthier lifestyles than others.
Chandigarh has been ranked as the healthiest city in India, according to the GOQii India Fit Report 2020. The report surveyed about five million people to understand the health and lifestyle of Indians. It found that only 38% of Indians were healthy, with Kolkata scoring the lowest due to the highest incidence of diseases like diabetes, cholesterol, blood pressure, and thyroid issues.
Aizawl, the capital of Mizoram, is also known for its clean air. Located over 1100 meters above sea level, Aizawl offers fresh mountain air and stunning views. Its PM2.5 level is 13.8 µg/m³, which is considered 'Good' and safe for outdoor activities. The city's thick greenery, fewer factories, and less traffic contribute to its clean air.
Koppal, a town in Karnataka, is another example of clean air and a healthy environment. Surrounded by hills and farmlands, Koppal has a low PM2.5 level of 16.3 µg/m³, which is well below the harmful range. The town has fewer industries, less traffic, and natural landscapes, all contributing to its low air pollution levels.
Other cities in India with relatively better air quality include Gadag in Karnataka, known for its temples and traditions, and Bengaluru, which is the 13th least polluted city in the country. While big cities like Delhi continue to struggle with poor air quality, these examples show that clean air and healthier environments are still possible in India.
