Even as India gears up to meet emission targets, Mumbai’s new suburban trains have already begun cutting down 40 per cent carbon emissions, claim railways.
India has promised to a reduction by 20 per cent by 2020 at the Copenhagen climate change summit.
“The Copenhagen summit wants India to cut down 20 to 25 per cent of carbon emissions. Here is a project in Mumbai that has already cut down emissions by 40 per cent. I think we can compensate for other government bodies,” P.C. Sehgal, managing director of Mumbai Railway Vikas Corporation told Hindustan Times.
The regenerative braking system in the new trains generates about 30 per cent electricity. This regenerated electrical energy is reused by other trains on the same service line. This leads to reduction of power consumption as less power is drawn from the electrical grid that provides power to western India. In this way it conserves electricity and reduces green house gases.
Energy saving by these new trains will get translated to a saving of Rs 100 crore annually as 250 million units of energy are saved.
The Mumbai train project is also set to be a part of the Clean Development Mechanism project of the United Nations Framework Convention on Climate Change (UNFCCC). The Mumbai Railway Vikas Corporation has already submitted a project idea note to the clean development mechanism executive board at Bonn in Germany, for issuance of certified emission reductions.
According to estimates, by using this system, the railways hope to reduce greenhouse gases by 5.21 lakh tonne of CO2e (Carbon dioxide equivalents) over a 10-year period, between 2009 and 2019.
Officials said that Mumbai’s new trains will be a template for other electric trains in
the country and the railway ministry plans to extend the project to other regions in the country.
