Environmental Activities

A global approach of consolidated environmental management.



Isuzu, as a global company, has the responsibility to introduce environmental-friendly vehicles and diesel engines, working together with group companies to preserve our environment.

Isuzu is taking the lead in consolidated environmental management in order to preserve our planet.
The Isuzu Charter on the Global Environment was established in 1992 to implement environmental measures using various approaches. All divisions conduct business with an awareness of environmental conservation - the Engineering Division creates clean fuel efficient vehicles, the Purchasing Division promotes green procurement, the Manufacturing Division reduces the environmental burden in the manufacturing process, and the Sales Operation Support Division conducts seminars on fuel efficient driving. Furthermore, Isuzu has adopted an ISO 14001 environmental management system in order to reduce the environmental impact of corporate activities continuously and to strengthen the company's awareness in environmental management. Isuzu became the first domestic truck manufacturer to receive this ISO certification in 1998, with implementation beginning in the Manufacturing Division and spreading to the entire company by 2002, including the Engineering Division and major overseas plants. In 2004, Isuzu began a program of consolidated environmental management designed to reduce the entire group's impact on our planet. Initially, eight domestic manufacturing companies, six overseas manufacturers and every domestic dealer implemented measures, with all manufacturing companies having acquired ISO 14001 certification by May 2005. Domestic sales companies continue to follow up with conservation activities based on Isuzu's original guidelines on environmental action. The consolidated management system will gradually be expanded to other group companies. In addition, in accordance with the Automotive Recycling Law in Japan, Isuzu is promoting various measures, such as controlling customer/vehicle information, establishing Isuzu's own recycling system and building up dealers' computer systems. The goal of making vehicles 90% recyclable beginning with the 2002 model year has already been achieved and efforts are currently underway to meet the next legislative target of "a 95% or higher recycle ratio of used vehicles in 2015."

Isuzu is developing practical and economical low-pollution energy vehicles plus clean diesels.
For effective use of fossil fuel and protection of our natural heritage, Isuzu is making an intensive effort to bring clean energy vehicles to market, in addition to developing cleaner diesel engines. In urban areas where driving distances are short and reducing air pollution is a priority, vehicles powered by compressed natural gas (CNG) engine are being launched, while hybrid vehicles, which require no infrastructure change, have proved ideal for short to medium distances.
The Isuzu ELF and FORWARD compressed natural gas (CNG) trucks are currently in mass-production. The ELF CNG in particular has proven its popularity, taking 79%* domestic market share in 2006. In a 2007 full model change, CNG engines meeting 2005 new long-term exhaust emission regulations were further refined for cleaner performance, reducing 85% of NOx and 75% of NMHC (non-methane hydrocarbons) compared to standards. In addition, the idling stop & start system is standard on these vehicles, a first in the CNG vehicles.
The ELF diesel hybrid was launched in 2005 and underwent a full model change in 2007. With its lightweight and compact 3-liter engine, "Smoother-Ex" mechanical automatic transmission, original PTO-type parallel drive system and long-life lithium battery, the ELF diesel hybrid offers the reliability needed in a commercial vehicle as well as low fuel costs and reduced CO2 and emission gases.
