Environmental Issues

The Japan Auto Parts Industries Association (JAPIA) has formulated and implemented the 8th Environmental Voluntary Action Plan as a countermeasure against global warming and has achieved a 16% reduction in emissions by 2018 if the 2007 figure is set at 100. We also manage chemical substances in our products and implement initiatives for the life cycle assessment (LCA) of automobiles.

2. Advanced company tour,
Case Studies, and Issuing guidance

The JAPIA, as part of its environmental protection activities, organize tours of the facilities of companies that have introduced and implemented a variety of advanced initiatives with the aim of improving technologies related to global warming prevention and promoting mutual exchange.

In addition to the above, we are working to raise the level of our member companies efforts through the publication of "Case Studies of Energy Conservation Measures", "Waste Reduction Case Studies", "Water Resource Reduction and Improvement Case Studies", "Guidance on Effective Use of Water Resources", "Guidance on Labeling and SDS Compliance" and "List of Laws and Regulations for Chemical Substance Management in Factories" and other publications.

3. Study Session on Regulation of Chemical Substances in Products 

The JAPIA, in response to requests from its members involved in operations related to environmentally hazardous substances, holds study sessions on the "Basic Content of Laws and Regulations" and "Latest Trends in Major Regulations".

The study session was attended by not only JAPIA members but also OEMs and non-members of the supply chain to raise the level of the entire supply chain and was highly evaluated.


Study Group Agenda

The basics of the legal system; Approach to Substance Survey Approach to Chemical Substance Management Regulatory Basics for Product Environment

Latest Developments in Major Regulations; Chemical Substances Control Law North America (federal and state laws) Europe REACH ELV regulations in each country.


4.Developed and released a tool for calculating the lifecycle environmental impact of LCA automotive parts, such as CO2.
In 2013, the JAPIA released "
LCI* Guidelines and Calculation Tool" to provide a method for calculating the LCA for auto parts, in order to efficiently calculate the environmental impact at the manufacturing stage, which used to require a complicated survey. Subsequently, we published in 2016 "LCI Guidelines/Calculation Tool (Manufacturing + Use stage)" on how to calculate the environmental impact of automotive parts themselves at the stage of use of vehicles with high environmental impact. In March 2018, JAPIA received the "Director-General's Award of the Industrial Technology and Environment Bureau of the Ministry of Economy, Trade and Industry" at the LCA Japan Forum Awards in recognition of these LCA activities.
In June 2019, JAPIA developed and released standardized data on the environmental impact of typical automotive parts and tools for calculating the environmental impact of each stage of the product’s life cycle so that member companies can objectively evaluate the environmental performance of their products, and held a briefing session on tools for calculating the environmental impact of CO2 and other substances in the life cycle of automotive parts.
