Delhi's poor air quality navigating sustainable transport solutions for cleaner skies

Delhi, a bustling metropolis, grapples with a persistent struggle against air quality challenges that extend far beyond the fleeting haze surrounding Diwali celebrations. In a global comparison, the city's air quality paints a concerning picture throughout the year, revealing significant disparities when measured against other cities of similar stature. The World Health Organization's Urban Ambient Air Quality database underscores Delhi's worrisome annual PM10 levels, which averaged a staggering 230 micrograms per cubic meter (μg/m3) between 2011 and 2015. This alarming statistic starkly contrasts with the relatively lower levels observed in cities such as Mumbai, Kolkata, Dhaka, Cairo, Beijing, Shanghai, Istanbul, São Paulo, and Buenos Aires.

A Multifaceted Predicament

The complexity of Delhi's air quality issue transcends the realm of seasonal factors like agricultural burning and festive fireworks. Central to this multifaceted challenge is the continual contribution of the city's transportation sector. Consequently, the adoption of cleaner and more sustainable transport alternatives emerges as a crucial and enduring strategy in the quest to enhance Delhi's annual ambient air quality.

Pioneering Clean Transport Initiatives

In the early 2000s, the city mandated the adoption of compressed natural gas (CNG) as an eco-friendly alternative fuel for both public transport vehicles and the informal shared transit fleet, popularly known as paratransit. While this transition yielded commendable benefits, the city's burgeoning motor vehicle fleet has since overshadowed these gains. Notably, the number of motor vehicles in Delhi has more than doubled, surging from approximately 4.5 million in 2006 to over 10 million in the present day.

Strategic Measures for Sustainable Solutions

Addressing this escalating concern demands the exploration and implementation of several strategic initiatives:

Removal of Diesel and Petrol-driven Private Vehicles:

The removal of diesel and petrol-driven private vehicles holds significant potential in mitigating Delhi's persistent struggle with air pollution. These vehicles are major contributors to the city's deteriorating air quality, emitting a substantial volume of pollutants and particulate matter into the atmosphere on a daily basis. Eliminating their usage represents a crucial step toward fostering a cleaner and healthier environment for Delhi's residents.

Encouraging Modal Shift to Public Transport:

Transitioning private vehicle users to public transport necessitates the development of innovative systems that cater to the quality expectations of private vehicle users. Comfortable passenger spaces, convenient pick-up and drop-off points, and on-demand transport services serve as crucial elements in facilitating this transition. Leveraging shared app-based public transport models and mini-buses operated by bus aggregators can play a pivotal role in optimizing fuel usage and reducing emissions per passenger.

Embracing Electric Mobility:

Initiating a substantial shift towards electric vehicles (EVs) warrants sustained governmental efforts, starting with the incorporation of EVs into official fleets to set an example for the general public. Incentivizing the adoption of electric mobility within the market and conducting widespread awareness campaigns that highlight the advantages of EVs can further stimulate consumer interest and participation.

Enhancing Last-Mile Connectivity to the Metro:

Improving last-mile connectivity to the Delhi metro system can broaden its accessibility and appeal to a wider segment of the population. Direct access points from prominent residential and commercial complexes can serve as catalysts for increased metro usage among residents and commuters.

Integration of Transport Systems:

Streamlining Delhi's fragmented transport system, encompassing separate metro, bus, paratransit, and suburban train services, is essential for providing seamless and comprehensive end-to-end connectivity. Establishing a centralized agency, akin to Transport for London, dedicated to orchestrating and managing the diverse transportation networks, can foster a more cohesive and integrated approach.

Undoubtedly, the implementation of these transformative changes will demand substantial effort, necessitating comprehensive research and a sustained, multi-year commitment. However, initiating these reforms in the nation's capital, poised to become one of the most populous cities globally, holds the promise of immediate and enduring benefits, particularly in the context of urgent air quality management and sustainable urban development imperatives.

Transportation serves as a significant contributor to Delhi's air quality concerns, yet prioritizing the adoption of clean transport practices offers a viable and indispensable solution. Swift and decisive action is imperative to ensure a cleaner and healthier environment for the city's residents and future generations.


Delhi's battle against air pollution requires a multi-faceted approach, encompassing robust policies, technological advancements, public participation, and collaborative efforts. By addressing the root causes and implementing sustainable measures, the city can aspire to achieve a cleaner and healthier environment for its residents and future generations.

In the quest for cleaner skies and a healthier urban environment, embracing sustainable transport solutions stands as a pivotal and non-negotiable stride toward securing a brighter future for Delhi and its inhabitants.
