UN Body Credits Delhi Metro- 6.3 Lakh Carbon Credits for Modal Shift Project

The Delhi Metro Rail Corporation has been certified by the United Nations(UN) as the First Metro Rail and Rail based system in the world which will get carbon Credits for reducing Green House Gas Emissions as it has helped to reduce pollution levels in the city by 6.3 lakh tons every year thus helping in reducing global warming.

Today about 18 lakh people travel in the city’s Metro Rail system which is completely non-polluting and environment friendly and, but for the Metro these people would have traveled by cars, busses, two/three wheelers etc which would have resulted in emission of green House Gases such as CO2, CO, HC, NOx, PM and SO2. Thus, DMRC has helped in reduction in 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 and thus earned carbon credits worth about Rs.47 crore annually for the next seven years and with the increase in number of passengers, this figure shall increase.

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. It is difficult to give documentary proof of the difference of energy consumption of two scenarios, i.e. “With Metro and Without Metro”. DMRC proposed an innovative method of proving the emissions using sampling techniques. After rigorous persuasion the UN body has finally agreed with this technique as the technique is very scientific in nature.

Delhi Metro has helped remove more than 91 thousand vehicles from the roads of Delhi daily. During the last two decades Delhi had an exponential growth in the vehicular population having more vehicles than the combined number in the other three Metro cities of India viz. Mumbai, Chennai and Kolkata. More than 90% of vehicles circulating are personal vehicles. In absence of the project the passengers move from their trip origination to their trip destination by buses, by taxis, by cars, by motorized rickshaws and by NMT (Non Motorized Transport). In the baseline situation or business-as-usual scenario, these modes of transport would continue to operate and transport passengers from their trip origin to their trip destination. With the construction and operation of Delhi Metro, the Metro complements other modes of transport and replaces partially trips made by conventional or traditional means of transit by Metro. The CDM project replaces trips made by conventional transport modes with Metro, being a more efficient, faster, safer and more reliable transport means. Emission reductions are achieved through reducing GHG emissions per passenger-kilometer, comparing conventional modes of transport with Metro. The resource efficiency of transporting passengers in Delhi by Metro has improved i.e. emissions per passenger kilometer are reduced compared to the situation without project i.e. had the Delhi Metro not operated.

This is the second CDM project from DMRC to be registered with the UN body in the last three years. DMRC’s first CDM project on regenerative braking had also achieved many international firsts apart from earning valuable foreign exchange for the country.

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