LCA is a method to

For example, if two cars
with the same displacement of 2,000 liters are evaluated in the Life Cycle Assessment, purchasing the one that is evaluated as having less environmental impact would be an environmentally
The most effective way

In 2003, as many as 19 years ago, the power-saving device (Setsuden-mushi) I developed in the past was calculated its environmental
impact using this life cycle assessment method and also evaluated for its environmental impact reduction effects by the power-saving device itself, which led to Type III EcoLeaf environmental
label certification as the 3rd one in Japan, (See attached label) and the news was covered by the local TV station.
