Proper Management of Chemical Substances

There are a wide variety of chemical substances on Earth, with over 100,000 types that are commercialized. While they allow us to lead convenient lives, they can also have an impact on human health and other factors.
For substances that are clearly harmful, regulations are enforced by law.

PRTR System

Chemical substances are also regulated by the national law regarding the understanding and improvement of the management of emissions of specific chemical substances into the environment.

The PRTR system is a system that understands, aggregates, and publishes the amount of chemical substances emitted into the environment and the amount transferred off-site in waste based on reports from businesses and national estimates.
