Seven Eleven Japan, the convenience store plans to equip all its new stores with LED-based signboards and outdoor lighting. The effort is to reduce emissions of global warming gases. LEDs will likely be able to allow 7-11 to cut its carbon dioxide emissions by 3%, or 1.8 tons per store per year times 1000 new stores each year.
The Seven & i Holdings Co. estimates that it will spend more than 1 billion yen a year on LED lighting. An initial investment per new store will cost 1-2 million yen. Down the road, Seven-Eleven Japan is expected to use roughly 75% less power than fluorescent lights, thus getting back their investment. LED lights also last four to five years, compared with a year or so for fluorescent lights.
Rival convenience store operators, Lawson Inc., FamilyMart Co. and Circle K Sunkus Co. have been testing LED-based signboards, however, 7-11 is the first to take the plunge on a large scale.
Convenience store operators are also turning to more power-efficient air conditioning to reduce their CO2 emissions.
Shall we call this a convenient truth?
