Mumbai Metro One Private Limited (MMOPL) is a joint venture between Reliance Infrastructure Limited, Mumbai Metropolitan Region Development Authority (MMRDA), and Veolia Transport SA. It was established in 2008 to develop, operate, and maintain the Mumbai Metro Line 1, which is a 12.4 km long elevated corridor connecting Versova in the western suburbs of Mumbai to Ghatkopar in the eastern suburbs. The line has 12 stations and carries around 4 lakh passengers daily.

MMOPL is committed to the decarbonisation of the transportation sector and reducing its carbon footprint. It has implemented several initiatives to achieve this goal, such as the use of regenerative braking technology in trains, which recovers the energy generated during braking and feeds it back into the power grid. This reduces the energy consumption of the trains and also helps to reduce the load on the power grid.

MMOPL has also implemented a corporate energy management system to monitor and manage its energy consumption. This system helps to identify areas where energy can be saved and optimised, leading to a reduction in energy costs and carbon emissions. The company has set a target to reduce its carbon emissions by 30% by 2030, and it is working towards achieving this goal through various initiatives.

One of the key initiatives taken by MMOPL to promote renewable energy is the implementation of a Corporate Power Purchase Agreement (PPA). Under this agreement, the company has signed a contract with a renewable energy generator to purchase a fixed amount of renewable energy at a fixed price for a specified period. This helps to promote the development of renewable energy projects and also ensures a stable supply of renewable energy for the company.

MMOPL has also installed solar panels at its stations and depots to generate renewable energy. These solar panels have a total capacity of 2.6 MW and generate around 3.5 million units of electricity annually. This helps to reduce the company's dependence on grid electricity and also reduces its carbon footprint.

In addition to promoting renewable energy, MMOPL is also committed to reducing its energy consumption through various energy-efficient measures. It has implemented LED lighting at its stations and depots, which has led to a reduction in energy consumption by around 50%. The company has also implemented a rainwater harvesting system at its depots to conserve water.

MMOPL is also committed to promoting sustainable transportation and reducing the use of private vehicles. It has implemented a feeder bus service to connect its stations to nearby residential and commercial areas. This helps to encourage people to use public transportation and reduce the number of private vehicles on the road.

In conclusion, Mumbai Metro One Private Limited is a leading player in the transportation sector in India, committed to the decarbonisation of the sector and reducing its carbon footprint. The company has implemented several initiatives to promote renewable energy, reduce energy consumption, and promote sustainable transportation. Its commitment to decarbonisation and sustainability is a testament to its vision of creating a sustainable future for the transportation sector in India.
