The project which has been taken up by the Delhi Metro Rail Corporation, India, and funded by JBIC, does not consider the benefit of Clean Development Mechanism (CDM), which could have resulted in substantial decrease in the fares being charged by the Delhi Metro. The benefits of CDM through the UNFCCC approved methodology could easily be passed on the commuters once the project is verified and certified by the DOE (designated operational entity). By not availing the benefit of CDM in this project, the cost of the project has been taken in a higher direction which could otherwise be reduced by the CDM and CERs occurring out of the benefits of the project. Also once the DMRC project is completed with the existing financial grants, the latest technologies could have been purchased which would have more impact into the environmental considerations.
