The Ministry of Economy, Trade and Industry (METI) and the Ministry of the Environment (MOE) have jointly totaled and estimated the released and transferred amounts of chemical substances in FY 2012. These substances are recognized to continuously exist in the environment of a considerably wide area and to pose a risk of being injurious to human health, or a risk of impeding the inhabitation or growth of animals and plants. Such substances are designated as Class I Chemical Substances under the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (Chemical Substances Management Act). The ministries hereby announce the compiled results of the statistics.

According to the notifications submitted by business operators, 381,000 tons in total of the chemical substances were released and transferred, down by 4.6% from the previous fiscal year. Data by individual business operators are available from today on the METI and MOE websites.

1. Background

In April 2001, the Pollutant Release and Transfer Register (PRTR) system was introduced under the Chemical Substances Management Act, which was promulgated in July 1999.

Under the PRTR system, every business operator that handles any of the Class I Designated Chemical Substances is required to notify the government of the amount of such chemical substances that they have released into the environment or have transferred to certain locations as contained in waste. Such Class I Designated Chemical Substances are chemical substances are recognized to continue to exist in the environment of a considerably wide area and to pose the risk of being injurious to human health or the risk of impeding the inhabitation or growth of animals and plants. The system also requires the government to disclose not only a tabulation of the data of which notification was submitted by the business operators, but also the estimated amounts of chemical substances that are supposed to be leased from entities other than the business operators concerned.

The PRTR system under the Chemical Substances Management Act was revised by the Cabinet Order in November 2008. In line with the revision, the coverage of chemical substances of which notification is required was also changed from 354 to 462 substances, subject to those notified in FY2014. At the same time, the medical industry was newly introduced to the coverage of the system, resulting in the total number of industries that are required to submit a notification coming to 24.

Jointly with MOE, METI totaled the released amount of such substances, as well as estimating and calculating the amounts that are supposed to be leased from entities other than the business operators, and compiled the results.

The compiled data and the data by business operator have been publicized on both the METI and MOE websites on March 6, 2014.
