As Pune prepares to implement a Low Emission Zone (LEZ), an important question lies at the centre of the discussion: how can cities legally regulate high-polluting vehicles?
Low emission zones (LEZs) are designated zones in a city where the use of polluting vehicles is restricted or discouraged. Such zoning aims to improve local air quality and health by reducing vehicle tailpipe emissions. One pathway to implement LEZ is straightforward restriction – banning old polluting vehicles from entering identified areas. The other is more strategic; using pricing mechanisms to discourage the use of polluting vehicles while also generating resources to support sustainable transport initiatives.
ITDP India is working with Pune to implement the idea of introducing a charge on high polluting vehicles. Instead of relying solely on bans, the aim is to introduce a levy on older and more polluting vehicles entering the LEZ. How this can be done is simple: create a system where cleaner mobility becomes the easier and more affordable choice.
However, choosing “pricing” is not just a policy shift. It is also a legal one.
In order to kick-start a LEZ, the legal pathway used to introduce these charges must be carefully structured. The legislation supporting it, the authority under which the charge is introduced, and terminology used will determine whether the system can withstand legal scrutiny.
Understanding the Existing Legal Landscape for Clean Air
India does not currently have a single consolidated law governing Low Emission Zones. Instead, implementation depends on multiple laws and authorities working together. At the constitutional level, the right to a clean environment is recognised under Article 21, while Article 48-A places a duty on the State to protect and improve the environment.
Beyond this constitutional backing, several legislations create the broader framework within which an LEZ can operate.
- The Environment (Protection) Act, 1986 (EPA) grants the Central Government wide powers to regulate polluting activities and restrict certain areas when necessary for environmental protection.
- The Air (Prevention and Control of Pollution) Act, 1981 empowers both the State Pollution Control Board and State Government to plan and implement pollution-abatement programmes, including issuing binding directions.
- The Motor Vehicles Act, 1988 allows State Governments to regulate vehicle movement in the interest of public safety and convenience.
Meanwhile, the Maharashtra Municipal Corporations (MMC) Act, 1949 directs municipal corporations to undertake environmental protection measures. However, the Act currently does not explicitly empower the city to levy environmental charges linked to vehicular pollution.
This gap becomes central when discussing how Pimpri Chinchwad Municipal Corporation (PCMC) and Pune Municipal Corporation (PMC) can independently implement a pricing-based LEZ.

What are the Possible Legal Pathways for Indian Cities to Introduce Pricing in LEZ
To better understand how pricing can be introduced within a Low Emission Zone (LEZ), ITDP India conducted a legal study in the context of Pimpri Chinchwad. The objective was to identify the various legal pathways available for introducing a pricing mechanism and assess which of them could provide a legally robust foundation. The study identifies three possible pathways through which an LEZ and its associated pricing mechanism could be implemented. While the analysis was undertaken for Pimpri Chinchwad, these pathways may also be relevant for other cities in Maharashtra, including Pune. However, they should be viewed as potential legal options rather than definitive solutions. Their feasibility will ultimately depend on discussions with the respective city corporation and a detailed assessment of the city’s legal and administrative context.
Option I: Implementing Pricing underthe Air (prevention and control of pollution) Act 1981)
Approaching the Maharashtra State Government under the Air Act provides one of the most viable legal pathways for introducing pricing under a Low Emission Zone. As Maharashtra is already declared an Air Pollution Control Area, the State Government can impose targeted restrictions and environmental charges to address air pollution.
Under the same Act, the Maharashtra Pollution Control Board (MPCB) is empowered to plan and implement pollution-abatement measures, issue binding directions, and collect restitutionary damages linked to environmental harm. Together, these provisions provide a strong legal basis for introducing pollution pricing through an LEZ.
Option II: Implementing Pricing under the Maharashtra Municipal Corporation Act (MMC), 1949
This pathway enables greater local autonomy but also presents the greatest legal challenge. Under the MMC Act, municipal corporations such as PMC and PCMC can regulate transit and impose certain special charges, but only after getting approval from General Body. Further, the Act does not provide authority to levy environmental charges linked to vehicular pollution.
As a result, cities seeking to independently implement a pricing-based Low Emission Zone would require legislative amendments. In Maharashtra, this would involve strengthening Section 208 of the MMC Act. At present, Section 208 permits the levy of special charges primarily in cases involving physical damage to roads or traffic obstruction, but it does not explicitly recognise environmental protection or air pollution control as valid grounds for imposing such charges.
A stronger legal foundation would require amending the provision to:
- explicitly recognise environmental protection and vehicular pollution control as legitimate grounds for regulating vehicle movement and levying special charges
- authorise the levy of environmental charges for these purposes through the existing mechanism under the Act, including the requirement for approval by the Corporation.
Option III: Implementing pricing under the Environment (Protection) Act, 1986
This pathway relies on action by the Central Government through the Ministry of Environment, Forest and Climate Change (MoEFCC). While it provides a strong legal basis for implementing a Low Emission Zone (LEZ), it is less likely to be pursued directly by a city, as the necessary powers rest with the Central Government.
The Environment (Protection) Act provides wide-ranging powers to protect and improve environmental quality. In the context of an LEZ, the most relevant provisions include the power to:
- restrict areas where certain operations or processes may be prohibited or permitted only subject to safeguards (Section 3(2)(v))
- issue binding directions for the regulation or prohibition of activities contributing to pollution (Section 5)
- prescribe environmental standards and stricter emission limits for specific areas through the Environment (Protection) Rules, 1986
Using these powers, the Central Government could notify an area in Pune or Pimpri Chinchwad as a Low Emission Zone and prescribe restrictions or environmental charges for high-polluting vehicles. Since the necessary statutory powers already exist under the EPA, this pathway would not require amendments to existing legislation.
The Terminology Matters for Low Emission Zones: Fee vs Charge
At first glance, the difference between a “fee” and a “charge” may seem minor. Legally, however, the distinction is critical.
A fee is generally understood as something charged in return for a service or benefit provided to the payer. However, this creates a challenge for an LEZ. An LEZ does not provide a direct service to the driver entering the zone. Instead, it restricts access in order to protect public health and reduce environmental harm. If the levy is framed as a “fee”, it becomes vulnerable to legal challenges on the grounds that no direct service is being provided.
This is where the concept of an Environment Compensation Charge (ECC), or a “Special Charge”, becomes important.
Unlike a fee, an environmental compensation charge is linked to the idea of compensating for environmental harm caused by polluting activities. Judicial precedents already recognise the principle of restitutionary and compensatory damages in environmental matters. Framing the levy this way creates a far more resilient legal foundation for implementation.
Building Legally Resilient Low Emission Zones in Indian Cities
As Pune and Pimpri Chinchwad move closer to implementing Low Emission Zones, with Pune starting the preliminary phases from June 2026, the urgency of establishing a legally secure framework continues to grow.
If immediate implementation is the priority, pathways through the Central Government, State Government, or MPCB currently offer the strongest legal footing. Existing legislation and precedents already support the collection of environmental charges through these routes.
However, if cities seek greater local control and long-term autonomy, it requires legislative reform. In this process, terminology itself becomes a form of legal protection. Framing the levy as Environmental Compensation rather than a service-based fee could determine whether the city’s efforts withstand future legal scrutiny.
For a policy designed to improve air quality and public health in the long term, legal resilience will be just as important as technical planning.

Frequently Asked Questions
- What is a Low Emission Zone? A Low Emission Zone is a designated area where the older, polluting vehicles are either restricted, discouraged, or required to pay a charge to enter. The goal is to improve air quality by reducing vehicle emissions in areas with high pollution levels.
- Will an LEZ affect all vehicles? No. LEZs typically target vehicles based on their emission performance. Cleaner vehicles may be exempt, while older and more polluting vehicles may face restrictions or charges.
- How does a pricing-based LEZ work? Instead of completely banning vehicles, a pricing-based LEZ imposes a charge on vehicles that do not meet specified emission standards. The charge acts as a disincentive for using polluting vehicles, providing flexibility while still influencing travel behaviour. It allows vehicle owners to make choices while creating a financial incentive to shift towards cleaner vehicles or sustainable transport options.
- How can revenue collected through an LEZ be used? The LEZ charge is not designed as a revenue-generating mechanism. The primary intention of levying a charge is to discourage continued use of high polluting vehicles and gradually phase them out. Revenue from LEZ charges will support initiatives that directly reduce air pollution such as investing in procuring electric buses, and improving walking and cycling infrastructure.
