Use of Natural Refrigerants
It has been shown that HCFC gases are a factor behind global warming and the destruction of the ozone layer.
In 1988, the Montreal Protocol brought widespread attention to these difficult issues and in the same year, Japan introduced the Ozone Layer Protection Act. Since then, a succession of regulations governing the manufacture and import of specified HCFCs have been introduced and in 2020, production was abolished.
Since 2000, YOKOREI has been leading the industry by introducing ammonia as a natural refrigerant that does not contain HCFCs into all new logistics center.
In 2024, while the industry average for natural refrigerant use was around 50%,YOKOREI boasted usage of arounnd 72% and we are steadily advancing this initiative.
