The Liaison Council on Promoting Eco-Driving, a body consisting of the National Police Agency (NPA), the Ministry of Economy, Trade and Industry (METI), the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and the Ministry of the Environment (MOE), revised the 10 Recommendations for Eco-Driving, a compilation of recommended driving techniques that industries and associations make use of in disseminating and promoting ecologically-friendly driving, known as “eco-driving.”
1. Outline of the “10 Recommendations for Eco-Driving”
The council formulated the “10 Recommendations for Eco-Driving,” a compilation of recommended driving techniques, called “eco-driving,” in 2003 and, since then, it has been raising public awareness of eco-driving after the two partial revisions of the compilation in 2006 and 2012. Taking into consideration that a certain period of time has passed since the last revision in 2012, these ministries and agency and related associations and entities jointly examined the compilation to decide on whether or not specific items shown in the compilation should be revised.
They considered it important for drivers to ascertain the fuel efficiency of their vehicles, which is expected to work as a trigger for such drivers to tackle or continue to tackle eco-driving. Accordingly, the council revised the compilation, e.g., by transferring Item 10 “Ascertain the fuel efficiency of your vehicle” to the position of Item 1, and compiled new “10 Recommendations for Eco-Driving” as below (Appendix 1).
10 Recommendations for Eco-Driving
- Ascertain the fuel efficiency of your vehicle;
- e-Start: Accelerate your vehicle gently;
- Drive your vehicle with less acceleration and deceleration actions by keeping an adequate inter-vehicle distance;
- Release the acceleration pedal earlier when decelerating your vehicle;
- Use the in-car air conditioner appropriately;
- Stop inefficient idling of the engine;
- Avoid driving in traffic jams by leaving home a little earlier;;
- Start checking and maintenance with checking the air pressure of your tires;
- Unload unnecessary belongings from your vehicle;
- Do not park your vehicle where it blocks the passage of other vehicles;
2. Details of the leaflet of the “10 Recommendations for Eco-Driving”
In line with this revision of the compilation, the council prepared a leaflet of the compilation in order to raise public awareness thereof. The new leaflet was prepared to not only raise awareness of the compilation among drivers but also encourage drivers to learn about eco-driving with their children.. Moreover, the new compilation also explains the use of eco-friendly vehicles as well as tips about approaches to achieving eco-driving of hybrid and electric vehicles. Please see the leaflet (Appendix 2).
Utilization of application for fuel management as well as the filing-up-a tank method* and utilization of fuel measurement instruments** are well known approaches to ascertaining the fuel efficiency of vehicles.
The council, a body consisting of NPA, METI, MLIT and MOE, will strive to advance efforts for disseminating and promoting eco-driving in parallel with raising public awareness of the 10 Recommendations for Eco-Driving.
*1. The filling-up-a tank method is a method of calculating the fuel efficiency of a vehicle by using the data on the travel distance and the amount of consumed fuel (quantity refueled) from the date when the tank of the vehicle is filled up with gasoline at a gas station to the date when the tank is filled up next time. Users of a fuel management application can easily identify the fuel efficiency of their vehicles if they input such data as the total amount of gasoline supplied to the tank, the date when they have filled the tank with gasoline and the odometer distance.
**2. Fuel measurement instruments are instruments indicating the fuel efficiency of vehicles on the in-car display, which is calculated based on the amount of injected fuel and the travel distance, shown by the engine computer. Some types of such instruments show an instant fuel efficiency, which is calculated from the amount of injected fuel and the speed of a vehicle.
