Reports of CDM/JI Feasibility Studies: FY2009

Title of Feasibility Study (FS)CDM Project Feasibility Study on Energy Efficiency Activities Using Idling Stop Equipments for Buses in Jinan, Shandong Province, China
FYFY 2009
Main Implementing EntityJapan Weather Association
FS Partner(s)Jinan Public Traffic Company
Location of Project ActivityChina (Jinan City, Shandong Province)
Summary of FS ReportPDF (106KB)
Description of Project ActivityThe purpose of the small-scale project activity is to reduce GHG emissions from buses operating by Jinan Public Transport Group Company (JPTGC) in Jinan city, Shandong Province, China. The idling stop device was developed in Japan to prevail the idling stop technology for existing/used vehicles. It is possible to ease driving operation to stop idling compare to manual operations of turning the engine off and on by the ignition key. In the project activity, project entities install the post-fit type idling stop devices to total 2,000 numbers of existing/used buses. It is achieved the fuel saving with stop idling, as a result, it is expected average 4,000tCO2 emission reductions in one year during the project period. The air pollutant emissions such as NOx and PM are also reduced at the same time.

Methodology to be appliedThe new CDM methodology planned to be applied in March 2010 referred to as "Transport energy efficiency attained by Post-fit Idle Stop Equipment"
Baseline ScenarioBaseline scenario assumes that the bus installed with post-fit idle stop equipment will continue to use diesel fuel and to conduct idle stopping operation when such bus stops at terminal, signalized crossing, bus stops, traffic jam, etc.
Jinan Public Traffic Company (JPTC) does not have any plan to introduce new bus that the idle stopping system has been installed at manufacturer’s factory. The idle stop equipment of post-fit type is the first technology proposed to JPTC by Japanese side as a proven technology in Japan aiming at increasing of energy efficiency for bus operation.
This project is the first of its kinds in China that tries to introduce a similar technology. The regulation to enforce the idle stopping operation of vehicles has not been implemented neither by the Municipal Government of Jinan City, Provincial Government of Shandong Province nor by the Central Government of China. As such the application of post-fit type idle stopping system cannot be considered as the baseline.
Demonstration of Additionality
  • Technological barriers:
      In China, no post-fit type idle stopping device has been introduced yet. Furthermore, as there is no technology for measuring the influence on engine and bus mechanism because of the installation of post-fit type idle stopping equipment to vehicles and no record of such experience accumulated, the introduction of post-fit type idle stopping equipment has not been introduced yet. The project was the first experience for China to use the post-fit type idle stopping equipment as an experiment.
      JPTC, the executing body of the project, came to know about the post-fit type idle stopping system and device until when Japanese side proposed it to them.
      The JPTC has not been familiarized fully yet about the way of installation and operation of post-fit type idle stopping device.
      Under such situation, the training on how to introduce and operate the post -fit type idle stopping device is planned to be proposed to them from Japanese side. In such a way, it will be possible to overcome the technological barrier with the technical assistance provided by Japanese side to implement the project as the CDM project.
  • Barrier due to prevailing practice:
      In China, the domestic technologies for manufacturing the engine and mechanism has not been developed well similar to the level of Japan yet. Therefore, it is believed that the post-fit type idle stopping device cannot be applied to the vehicles of Chinese make although it is a proven technology in Japan.
      Under such situation, the resistance for the introduction of post-fit type idle stopping device has been strong yet. The full introduction of post-fit type idle stopping device through this project can be considered as the first case in China.
Estimation of GHG Emission Reductions3,936tCO2 per year (by 2,000 bus units)
Monitoring Plan
  • Monitoring structure: The monitoring structure for the project activity is shown below.
  • Monitoring equipment: The monitoring equipment is SD card writer to be attached to idling-stop device.
  • QA/QC: DOE shall visit the Jinan Public Transport Company each year for checking the inventory of idling stop equipment, data collected by SD card, preparation and storing of monthly reports, so as to recommend a necessary revision to the manager of vehicle management division in the headquarters if such revision is deemed necessary.
  • Data management: The personnel computer which is used exclusively for management and recording the data concerned with the idling stop operation shall be installed in the vehicle management division in the headquarters so as to store the inventory of idling stop equipment, data contained in SD card and monthly reports and prepare a necessary index system for reference. Those data stored shall be restored periodically as to back-up the system and data.
Environmental Impact AnalysisNo adverse environment impact is assessed. It is assessed that the use of idle stopping equipment is possible to save the fuel consumption during the period of stopping of vehicle at crossing, bus stop, traffic jam, etc. As the project does not associate with construction works, the project is not a subject of environment impact assessment analysis.
Project FeasibilityThe priority of action was given to overcome the technological barrier that hinders the introduction of post-fit type idle stopping device, as it was not possible to evaluate and implement actual introduction plan that include a determination of vehicle type, vehicle number and bus operation route until the time that the energy efficiency due to the use of idle stopping system can be verified and a stable operation of device as well as vehicle can be certified.
In March 2010, the JPTC expressed their expectation that the Study will be continued to make sure of the effects of the system and agreed to apply the methodology prepared as a new CDM methodology on small scale project. Under such circumstance, the application of methodology relevant to the Project is determined to be carried out as soon as possible.
It is estimated that the period needed for the registration of actual project to UNFCCC is around 16 months after the application of the new CDM methodology concerned.
Pollutants Emissions ReductionThe idle stopping system is possible to contribute effectively to improve the air quality in the area where the project will be implemented because of emission reduction of NOx, CO, PM, THC during the stopping period of Vehicle become available.
Contribution to Sustainable Development in Host CountryThe application and use of the post-fit type idle stopping device to a large number of vehicles will contribute to save the fuel consumption thereby reduce the volume of fossil fuel consumption as well as to reduce the air pollutants at the same time.
The installation of post-fit type idle stopping device to a large number of vehicles will push up the technical standards level of electronic technology of China concerned to automobile industry in general and automobile repair and maintenance industries in particular, thereby, the promotion of vehicle navigation system as well as ETC can be accelerated. In such a way, the project will possible to contribute to sustainable development of concerned industries in China.
