Non-Consolidated Data

In the past, Isuzu operated its environmental management structures on a site-by-site basis. With the revision of ISO 14001 in fiscal 2016, the systems were integrated on a Group-wide basis. In December 2016, we expanded ISO 14001 certification to all Isuzu sites, and shifted to ISO 14001:2015.
At present, Isuzu is carrying out uniform environmental initiatives across all sites. Moreover, we are undertaking company-wide efforts to reduce the environmental burden resulting from our business operations and to strengthen our environmental management.

Violations and Accidents Related to Environmental Laws and Regulations in FY2025

Isuzu had no violations or environmental accidents related to environmental laws and regulations during FY2025.

Reduce and Control Emissions

Trends in Waste Generation

Since FY2012, Isuzu has achieved zero emissions, with no waste being sent to landfills.

Trends in Plastic Product Industrial Waste Emissions

As Isuzu emits more than 250 tons of plastic product industrial waste annually, the company is classified as a large-volume emitter under the Act on Promotion of Resource Circulation for Plastics^*.
In accordance with the law, Isuzu has set goals for reducing and recycling plastic product industrial waste and implemented initiatives to achieve these goals. In FY2025, we successfully met our targets.
Isuzu will continue to accelerate its efforts to reduce waste and promote recycling, advancing methodical initiatives to achieve future targets.

Control Chlorofluorocarbon Emissions

In response to the Act for Control of Chlorofluorocarbon Emissions (Act on Rational Use and Proper Management of Fluorocarbons) effective from April 2015, Isuzu is promoting proper refrigerant management for business-use refrigeration air conditioning equipment and other equipment using chlorofluorocarbons at all of its bases, and is implementing inspections of all such equipment.
While this act requires business operators to report if their estimated leakage of chlorofluorocarbon exceeds 1,000 tons-CO₂/year, Isuzu has verified that its leakage volume for FY2025 was lower than this level.

Reduction of VOC Emissions

Isuzu is reducing emissions through the recovery of volatile organic compounds (VOC), has reduced VOC emissions from its plants and reviewed and improved its painting processes, which entail particularly large VOC emissions.
This activity is promoted through voluntary efforts to reduce VOC emissions by the Japan Automobile Manufacturers Association, Inc.

Trend in Total VOC Emissions

Proper Management of Emissions and Wastewater

By properly maintaining boilers and other smoke-generating facilities, we ensure that the amount of air pollutants from emissions such as nitrogen oxides (NOx) and sulfur oxides (SOx) is within regulatory standard values^*.
Further, wastewater from our plants is processed in a wastewater treatment facility before being discharged to sewer systems or public water areas. The discharged water is analyzed on a regular basis to ensure that it is within regulatory standard values.
