The PRTR system enables us to know what chemicals, from what kind of sources, and how much chemicals are released for each year.
The PRTR system is now widely adopted and implemented absroad. In Japan, The Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof was established in 1999.
The PRTR (Pollutant Release and Transfer Register) is a system that (i) requires businesses handling chemical substances potentially hazardous to the environment to estimate the amounts of chemical substances released and transferred in waste, and to report the data to their local governments, and that (ii) the national government then compiles data submitted and makes the results public.
PRTR aims to establish the common background of risk communication among the government, the business operators and the public by providing data about releases of chemical substances to the environment. These data also help the business operators to manage their own amount of releases. In consequence, it can contribute to reduce the environmental risks from chemical substances.
