The Hindu Business Line : Delhi Metro: First rail project on UN green list

New Delhi, Jan. 4 Delhi Metro has become the first rail sector project in the world to be registered at the UN under the clean development mechanism (CDM) scheme, enabling it to earn carbon credits.

By selling these carbon credits, Delhi Metro Rail Corporation (DMRC) would now earn Rs 1.2 crore per annum for a ten year period starting December 2007. DMRC can now claim 40,000 CERs per annum for a ten-year period.

Buyers

The buyer for the CERs is Japan Carbon Finance Ltd for the entire ten year period, which also funded the consulting study for the project. The project document was prepared by Indian office of Ernst and Young. This project is for the use of regenerative braking systems in trains wherein the kinetic energy released when the brakes are applied is supplied back to the overhead electricity lines. This results in about 30 per cent of electricity saving.

Car, bus usage

DMRC is also working on a project to claim carbon credits for the carbon dioxide emissions reduced on account of lesser usage of buses, cars by those commuters who have now shifted to the metro rail.

Incidentally, Indian Railways also uses locomotives with regenerative braking systems and acceptance of this methodology at the UN would make it easier for Railways to get its project registered.
