Depletion of Ozone Layer

The relationship between the ozone layer and chlorofluorocarbons, which is very important for us, has become clear in recent years, and action to protect this ozone layer is now needed around the world.

『Recently, it has been discovered that the ozone layer in the stratosphere blocks ultraviolet rays (1881) and plays a major role in allowing life on earth to live on land, and that holes have formed in the ozone layer, causing skin cancer, and that chlorofluorocarbon (CFC) gas is involved in its destruction (hole formation) (1974). Against this background, the ban on the use of CFC gas and its recovery needs to be completely implemented worldwide, without being limited to specific regions. In reality, however, even the production of hydrochlorofluorocarbons (HCFCs) has not yet been banned worldwide. We need to realize these forms of international regulatory compliance one by one and make them an important cornerstone of our activities to protect the earth.』
