Delhi strains to breathe every winter. Field fires, firecrackers, and bad weather patterns are frequently blamed. Television screens are filled with images of anti-smog cannons and towering air purifiers. However, even after the headlines have faded, the air remains harmful. Critics now argue that we have consistently ignored the true cause of Delhi's air pollution—its massive everyday traffic—in favour of more convenient seasonal scapegoats. 

This concern was highlighted this week at the Press Club of India recently, when Delhi SSANS (Swasth Saans Adhikar Nagrik Samiti), a new citizens' coalition, was officially formed. Doctors, attorneys, journalists, students, trade unionists, and impacted citizens comprise the group. Its central message was clear: the public debate on air pollution has been sidetracked by episodic causes, while the city's largest and most persistent source of emissions—private vehicles—is still insufficiently regulated. 

This viewpoint is supported by multiple scientific assessments. According to source apportionment studies, including one undertaken by IIT Kanpur, cars account for over 60% of Delhi's air pollution on average, followed by dust at 25%. Seasonal factors like crop residue burning and winter meteorology contribute to pollution levels, but they are not the primary reason. With roughly 13 million automobiles for a population of approximately 22 million, Delhi's daily traffic has practically become its most polluting machine. 

D. Raghunandan, former Delhi Science Forum secretary and president of the All India People Science Network, emphasised that arguing about minor differences in estimations diverts attention away from the main job. "How does it matter if the numbers are 21.2 per cent or 26.2 per cent?" he enquired. He stated that "the strategies will be the same in either case." According to him, research has already identified four to five major pollution sources, with automotive emissions and dust—both ambient and construction-related—leading the way, followed by industrial pollution in and around Delhi and emissions from thermal power plants. 

"If the system can address pollution caused by dust and vehicles, it can be significantly controlled," Raghunandan stressed, reinforcing the alliance's urge to prioritise structural improvements over cosmetic solutions. 

Leading attorney Prashant Bhushan and public health specialists described air pollution at the press conference as a violation of the constitutional right to life. Speakers warned against relying too much on "spectacle-driven" solutions, noting that smog towers and anti-smog cannons only operate within a 50- to 100-foot radius and for brief periods of time. One person likened it to putting a bandage on a deep interior sore. 

Experts also cautioned that people often overlook the most serious health hazards. Fine particulate matter, such as PM2.5 and PM10, can travel deep into the lungs and even into the bloodstream. Even when the air appears clear, toxic chemicals such as nitrogen oxides, carbon monoxide, and surface ozone continue to be detrimental, contributing to respiratory disease, cardiovascular stress, and shortened life expectancy. 

The Delhi SSANS says that the only long-term solution is to permanently reduce the number of automobiles on the road. "There is only one way of cutting down vehicular pollution, and that is by reducing their numbers," Raghunandan told the crowd. To achieve this, the group has recommended increasing Delhi's bus fleet from approximately 7,000 to over 15,000 vehicles, with a focus on smaller electric buses to service inner-city districts. Currently, approximately 30% of neighbourhoods lack a bus stop within 500 metres, forcing residents to rely on two-wheelers or private cars. 

The partnership has also called for serious planning around the city's underused Ring Railway, which has the potential to transport thousands of commuters daily if properly linked with bus and Metro services. While Delhi Metro now transports over seven million passengers each day, speakers emphasised that last-mile connectivity remains a major issue. "The solution lies in improving the mass transportation system; otherwise people will be forced to continue using their personal vehicles," he said. 

Participants emphasised the importance of restoring secure pedestrian and bicycle infrastructure. "Delhi should move people, not just vehicles," said a trade union leader, emphasising the daily challenges of workers who travel vast distances due to insufficient or expensive public transportation. 

The conference drew parallels with cities like Beijing, which achieved a significant reduction in air pollution in a decade by reducing vehicle use and upgrading public transit systems. Speakers claimed that Delhi might pursue a similar path—as long as it abandons short-term remedies and rethinks how mobility is designed. 

Citizens received a clear message: the fight for clean air is not seasonal. It happens every day, on every street.
