New Delhi: In a significant move, the United Nations has appreciated contribution of the Delhi Metro in reducing the pollution level. The United Nations has certified the Delhi Metro for the first metro rail-based system in the world to get carbon credits for contributing to the fight against climate change by reducing pollution levels in the city by 6.3 lakh tonnes every year.

The Delhi Metro Rail Corporation (DMRC) is the first institution to receive carbon credits from the UNO instead of not producing pollution.

Every passenger who chose to use Metro instead of car/bus contributes in reduction in emissions to the extent of approximately 100 gm of carbon-dioxide for every trip of 10 km and therefore, becomes party to the reduction in global warming.

The organisation has also earned carbon credits worth Rs 47 crore annually for the next seven years.

With nearly 18 lakh people taking the new age transport system every day, the Metro has helped reduce pollution and emission of green house gases as it is a completely  non-polluting and environment-friendly system.

"Thus, DMRC has helped in reducing emission of harmful gases into the city’s atmosphere and the United Nations Body administering the clean Development Mechanism (CDM) under the Kyoto Protocol has certified that DMRC has reduced emissions," Delhi Metro spokesman Anuj Dayal said.

No other Metro in the world could get the carbon credit for the above because of the very stringent requirement of the United Nations Body to provide conclusive documentary proof of reduction in emissions.

Emission reductions are achieved through reducing GHG emissions per passenger-kilometer, comparing conventional modes of transport with Metro, Dayal said.
