Clean Development Mechanism

DMRC has contributed significantly to arresting the process of climate change. It has developed following projects under the Clean Development Mechanism and the Gold Standard to demonstrate savings in CO2 emissions from its activities.

(i) Installation of low GHG emitting rolling stock in metro system, Project No. 1351
(ii) Metro Delhi, India, Project No. 4463
(iii) Energy Efficiency measures in DMRC Phase-II under the Gold Standard (ID. GS1246)
(iv) The MRTS PoA Project No. 9863

(v) DMRC Solar PV Project

(i) Installation of low GHG emitting rolling stock in metro system Project No. 1351:This was the very 1st CDM project to be registered by DMRC.
DMRC has electricity driven mass rapid transit system which uses 4 car or 6 car Rolling Stock on different service lines. The cars are equipped with 3 phase AC traction motors with regenerative braking system. By employing the regenerative braking technology, the DMRC’s trains are able to ‘generate’ electricity when brakes are applied. On an average 35% of electricity is regenerated and on a per kilometer basis, 5.26 kWh/Km of energy is regenerated. The electricity generated in braking is fed back into the system and is utilized by other trains which are in the loop at different locations on the track and are not in the braking mode. The electricity regenerated by trains in braking mode is used by trains in other modes of operation. This translates into reduction of load on the grid equivalent to the amount of electricity regenerated. In the absence of regenerative braking system, this requirement for electricity would have been met by drawing power from the national grid. Since the power plants use coal which releases enormous amount of CO2, we have, to that extent, avoided such emissions.

For a ten year crediting period (2007 to 2017), the estimated emission reductions are 41,160 tonnes of CO2 (e) average per year.

(ii)Metro Delhi, India, Project No. 4463: The essence of this project is that the carbon footprint of people travelling by metro is much lesser than that of the same journeys performed by other modes of transport i.e. private vehicles. The non-metro modes of transport are not only less efficient in terms of fuel economy but also are more polluting.

In the project situation the metro complements other modes of transport and replaces partially trips made by conventional or traditional means of transit by metro. Metro, being a more efficient, faster, safer and more reliable transport means Emission reductions are achieved through reducing GHG emissions per passenger-kilometre, comparing conventional modes of transport with metro. The calculation of amount of GHG saved is based on Approved Combined Methodology (ACM)-16 which has been pioneered by DMRC and approved by UNFCCC. Over a seven year crediting period, commencing June 2011, the estimated annual average emission reductions are 5, 29,043 tCO2 (e).

(iii) Energy Efficiency measures in DMRC Phase-II under the Gold Standard (ID. GS1246): Delhi Metro Rail Corporation (DMRC) is the first metro and railway system in the world to be registered (Registered on 6th January 2014) with The Gold Standard Foundation with project ID GS1246. Title of this micro scale Project Activity is Energy Efficiency measures in DMRC Phase II stations’.
The project activity involves energy efficiency measures undertaken by DMRC in a number of station buildings forming a part of Delhi Metro Phase-II following ECBC Code to the extent possible.

The total annual energy consumption is approximately 70 KWh/sqm for phase-I stations while for phase II stations it is 46.6 KWh/sqm, thus resulting in a total reduction of 23.4 KWh/sq m.
Since the project is more efficient as compared to Phase-I of Delhi Metro, it consumes less electricity and has resulted in reduction of 12195 tonne of CO2 equivalent for a period of 2 years. Such benefits of emission reduction will be available for next 10 years.

(iv) The MRTS PoA Project No. 9863: The MRTS PoA will consist of a series of MRTS projects (like Metro Rail, LRT, Monorail etc) implemented across India. Delhi Metro Rail Corporation Ltd (DMRC) will act as a Coordinating / Managing Entity (CME) for the PoA and would provide an open platform for different agencies to participate in the PoA developing their own CPA. As the proposed transportation system is more efficient compared to the traditional means of transport in the baseline, the project activity achieves emission reductions through improved efficiency in the transportation and calculated per passenger-kilometer. On average, MRT system has lower GHG emissions per passenger kilometer than those used in the absence of the project activity, hence, results in GHG emission reductions. The emission reductions under this programme will therefore be calculated according to the consolidated CDM methodology ACM0016 - “Mass Rapid Transit Projects”. The projects will be implemented under the Programme of Activities (“PoA”) approach and has been designed in such a way that individual, national and international project developers and financers may join the programme to improve the financial viability of the projects with the introduction of carbon revenues. Project has potential to generate more than 6 lakhs CERS annually just from phase-3 operations.

Upcoming Metro projects across India can avail benefits of CDM through DMRC’s MRTS PoA. DMRC will act as umbrella for all other upcoming MRTS projects interested to join MRTS PoA.

(v) DMRC SOLAR PV Project: On 25th March 2017, DMRC’s initiative on Solar PV roof-top installations became the first CDM project to be registered with UNFCCC for any metro or railways.
This project falls in the small scale category – those that have a threshold of less than 15MW of installed solar capacity and is a part of the “Renewable Energy PoA in India” whose Coordinating Managing Entity (CME) is “Emission Reduction Services Private Limited”.
In this, DMRC has implemented a new grid connected solar power plant in National Capital Region (NCR) at its metro stations, depot, parking areas, RSS and colonies. DMRC Solar PV Panels are installed at 31 locations of Delhi/NCR which encompasses of an installed capacity of 14.983 MW (DC) and estimated annual power generation and 19,687 MWh.
The emission reductions under this project will therefore be calculated according to the CDM methodology AMS-I.D.: Grid connected renewable electricity generation -Version 17, Sectoral Scope: 01. By this methodology, this project will generate an estimate of 18,506 CERs (carbon credits).
DMRC Solar PV Project will generate renewable power, which will displace part of the electricity that would have otherwise been supplied by a majority of fossil fuel fired power plants constituting the grid mix. Thus, GHG emission reductions can be achieved by avoiding the GHG emissions that would have occurred in the absence of the project activity.
