India's vibrant streets are not just alive with culture and activity but also with a less visible and more insidious companion: air pollution. While the country is struggling with some of the highest pollution levels globally, it's crucial to highlight significant contributors: vehicles. The Centre for Science and Environment's alarming revelation that vehicles contribute to 25% of PM2.5 emissions in India is a clarion call for immediate action.
PM2.5, the microscopic particulate matter, is a sneaky invader of human health, penetrating deep into the lungs and bloodstream, leading to respiratory ailments, heart disease, and even cancer. The list of the top polluting cars, once dominated by the likes of Maruti Suzuki Alto 800 and Hyundai Santro, all compliant with the now-outdated BS4 standards, tells a tale of a nation's struggle with modernity and sustainability.
The List of Concern: India's Top Polluting Cars
The cars that have made it to the infamous list of top polluters are a mix of old favorites and popular choices:
Maruti Suzuki Alto 800 (BS4): Once celebrated for its affordability, the Alto 800's BS4 engines are now a source of concern for their higher emissions.
Hyundai Santro (BS4): A family car that has served many Indian households, but now contributes significantly to urban pollution.
Maruti Suzuki WagonR (BS4): Known for its practicality, the WagonR's older models are falling behind in environmental friendliness.
Tata Indica (BS4): A pioneer in India's diesel hatchback segment, the Indica's emissions are reflective of its age.
Maruti Suzuki Alto K10 (BS4): Another variant of the Alto, the K10's performance comes at the cost of higher pollution levels.
Hyundai i10 (BS4): A popular urban car, the i10's BS4 version is not as kind to the environment as its successors.
Maruti Suzuki Celerio (BS4): Marketed as a city car, the Celerio's older models are part of the pollution problem.
Datsun GO (BS4): An affordable entry-level car, the Datsun GO's emissions are a concern for air quality.
Renault Kwid (BS4): The Kwid's appeal to the budget-conscious consumer is overshadowed by its environmental impact.
Maruti Suzuki Zen Estilo (BS4): Once a symbol of stylish compact cars, the Zen Estilo's BS4 engines are now outdated in terms of emission standards.
These vehicles, while compliant with the Bharat Stage IV (BS4) emission standards of their times, are now significantly more polluting compared to the newer BS6 compliant vehicles. The transition from BS4 to BS6 was a necessary move by India to reduce vehicular pollution, as BS6 standards are much stricter, especially in terms of nitrogen oxide (NOx) and particulate matter (PM) emissions.

Why Are These Cars Polluting?
The cars on this list are primarily there because of their outdated emission standards. BS4 vehicles release higher levels of pollutants due to less efficient fuel combustion and emission control technologies compared to BS6 vehicles. Additionally, the sheer number of these vehicles on the road amplifies their impact on air quality.
What Is The Government's Response?
The Indian government has taken proactive steps to combat vehicular pollution. The introduction of BS6 emission standards, which are on par with Euro 6, is a significant step forward. The promotion of cleaner fuels, investment in public transportation, and the proposed vehicle scrappage policy are all measures aimed at reducing the number of polluting vehicles on the road.
The Path to Cleaner Air
As individuals, we can contribute to reducing pollution by:
Choosing Cleaner Vehicles: Opt for BS6 compliant or electric vehicles when purchasing a new car.
Regular Maintenance: Keep your vehicle in top condition to minimize emissions.
Embracing Alternatives: Use public transport, carpool, or non-motorized transport whenever possible.
