Management and Reduction of Chemical Substances
Daikin bases around the world take voluntary action to reduce the amounts of various chemical substances, such as PRTR substances and VOCs. From fiscal 2016, we are working toward a target of reducing emissions per unit of production (total of PRTR substances and VOCs) in fiscal 2020 by 5% against the standard value (average for fiscal 2013-2015).
In fiscal 2017, our Chemicals Division strove to reduce emissions of the raw material methylene chloride and our Air Conditioning Manufacturing Division strove to reduce emissions of volatile processing oil, resulting in a 5% reduction against the standard value.
PRTR Law (Pollutant Release and Transfer Register (PRTR) Law)
Enacted in Japan in 1999, the PRTR Law is a legal framework in Japan for the calculation and publicizing of the amounts of certain hazardous chemical substances that are emitted or transferred as waste into the environment (air, water, and soil) or into public sewage systems. Other countries have similar regulations. The PRTR Law was revised in 2009.

Perfluorooctanoic Acid (PFOA) is a man-made chemical substance that has been conventionally used as a polymerization aid for fluororesins. It does not readily degrade in nature and is thus a substance of concern for the environment and human safety. At the end of 2015, as part of its efforts toward sustainable management of chemical substances, Daikin Industries, Ltd. ceased manufacturing and using PFOA and similar compounds, as well as products made from these.
