The move will also facilitate the fast-tracking of Clean Development Mechanism (CDM) registration of all upcoming rail based metro projects in the country which will entitle them to carbon credits for the extent of reduction in carbon emissions, which could be traded in the international carbon market for money.
PoA is a UN-mandated mechanism which allows similar carbon credit projects to be clubbed together that can be operated and managed under a single umbrella.
A recent study by the Central Road Research Institute (CRRI) claimed that Delhi Metro has helped keep more than 3.9 lakh vehicles off roads in 2014 thus saving Rs 10,364 crore in terms of less fuel consumption and other benefits.
In 2008, DMRC had become the first railway project in the world to be registered by the United Nations under the Clean Development Mechanism (CDM), enabling it to claim carbon credits.
