In September 2021, DMRC earned Rs 195 million from the sale of 3.55 million carbon credits that it accumulated over a six-year period from 2012 to 2018 in its quest for increased energy efficiency. DMRC has a number of projects aimed at increasing energy efficiency to its credit. Since 2015, Delhi Metro has also provided CDM consultancy services to other Indian metro systems, allowing them to collect carbon credits from their projects. Gujarat Metro, Mumbai Metro, and Chennai Metro, among others, have already registered their projects under the Delhi Metro’s Program of Activities, allowing them to earn carbon credits and contribute to India’s Intended Nationally Determined Contribution in accordance with the Paris agreement.
