With 65% solar energy use and eco-friendly infrastructure, Pune and Nagpur Metros aim to register for carbon credits, opening new revenue streams through global sustainability trade.
A Move Toward Monetising Sustainability
Maharashtra Metro Rail Corporation Limited (MahaMetro) has taken steps to monetise its environmental initiatives by pursuing carbon credit registration for the Nagpur and Pune Metro projects.
- A consultant is being appointed to evaluate and formally register the green practices adopted by both metro systems.
- These credits will allow MahaMetro to trade emission reductions in international carbon markets.

Metro Projects Powered by Clean Energy
Both metro systems have demonstrated strong green credentials, significantly reducing their carbon footprints:
- Up to 65% of energy needs are met through solar power from installations on station rooftops, depot walls, and vacant land.
- Other sustainable practices include rainwater harvesting, bio-digester sewage systems, and green building designs.
Notably, Nagpur Metro has achieved IGBC certification for its eco-friendly station infrastructure, placing it among India’s most sustainable urban transport systems.
Following the Delhi Metro Model
The move mirrors the success of the Delhi Metro, the first in the world to earn UN-certified carbon credits for its energy-saving and emission-reduction efforts.
- MahaMetro plans to include solar energy generation, regenerative braking, and the modal shift from private vehicles to metro in its carbon accounting process.
These efforts contribute to reduced fossil fuel use, a key criterion in the global carbon trading system.
Project Implementation and Revenue Potential
The carbon credit project is being jointly funded by the Government of India and Maharashtra State, and will roll out in two phases:
- Assessment and registration phase over 24 months
- Operational phase of 7 years for verified carbon credit generation and trading
- The selected consultant will perform detailed surveys and register with international carbon markets.
- As an incentive, the consultant will receive a performance-based share of the actual revenue generated.
Each carbon credit represents one tonne of COâ‚‚ reduction, and they currently trade between $5 to $25 globally. MahaMetro could potentially earn crores annually, depending on market rates and verified reductions.
Rapid Expansion and Ridership Growth
- Nagpur Metro currently operates 38 km across 37 stations, with Phase II adding another 43.8 km underway.
- Pune Metro has 33 km operational across two corridors, and is reporting strong ridership and revenue growth in recent months.
These expansions not only enhance urban connectivity, but also amplify the environmental impact by encouraging a shift away from private vehicle use, further increasing potential carbon savings.
MahaMetro is registering the Pune and Nagpur Metro projects for carbon credits, aiming to monetise eco-friendly operations like solar energy use and green infrastructure. With credits trading at $5–$25 per tonne, this move could generate crores in annual revenue while reinforcing India’s sustainable urban mobility goals.
