Seven & i Holdings is promoting various initiatives such as working together with original product manufacturing plants and delivery service providers and others to save energy at factories and introduce eco-friendly vehicles.
In addition to promoting the introduction of ecofriendly vehicles, Seven & i Holdings is working to improve fuel efficiency and reduce store delivery frequencies. Furthermore, progress is also being made in the introduction of drive-data terminals in trucks, which record driving conditions. Based on the collected data, drivers are instructed and eco-driving seminars carried out.
CO2 Emissions by Delivery Trucks
We are replacing delivery vehicles with hybrid trucks at SEJ. These are capable of recuperating energy generated during deceleration and then using it as secondary power to drive motors when pulling away and accelerating. Through this technology, we hope to realize fuel-efficiency improvements and reduced CO2 emissions, etc. There are 5,329 delivery vehicles in the fleet, as of May 31, 2016, and hybrid trucks account for 660 of these. We plan to replace 20% of the total fleet with eco-friendly trucks by 2020.
Number of Hybrid Vehicles Introduced
SEJ is promoting the introduction of eco-friendly tires that reduce the rolling resistance of the tires of delivery vehicles. As of May 31, 2016, we have installed eco-friendly tires on 5,289 delivery vehicles, representing approximately 99% of the total fleet.
Moreover, SEJ has also introduced retread tires to 8,000 vehicles*1, as of May 31, 2016. These tires are made from tires that have finished their service life by removing a certain amount of the tire surface that contacts the road and applying new rubber and tread. In this way, they can be re-used as rear tires for delivery vehicles. SEJ will promote the use of retread tires to contribute to resource conservation and waste reduction by reusing them.
SEJ is promoting efforts to reduce wasted power usage at its distribution centers by introducing "demand controllers" that monitor the electricity usage of each unit of equipment and apply controls to the equipment in use to ensure that the usage does not exceed a certain range. As of May 31, 2016, the controllers have been introduced at 69 of SEJ's 149 distribution centers.
SEJ has its original daily products manufactured by several contract manufacturers. These manufacturers have organized the Nihon Delica Foods Association, which reports on the CO2 emissions, waste emissions, and the food recycle rate associated with plant operations. We work to ascertain environmental information shared by our contract manufacturers and hold study seminars in conjunction with the Environment Countermeasures Committee of the Nihon Delica Foods Association, where we share environmental measures such as energy-saving with each manufacturer in an effort to reduce energy use at their plants.
