Reducing Environmental Impact from Substances

Efforts to reduce the environmental burden from chemical substances
In an EU directive related to end-of-life vehicles (ELV), the use of chemical substances such as lead, mercury, heptachrome, and cadmium will be gradually curbed starting from July 2003. Domestically, the Japan Automobile Manufacturer's Association (JAMA) has also called on manufacturers to take voluntary measures to reduce the use of these same four substances from here on.
In order to reduce the impact on the environment from landfill shredder dust, companies are doing there best to reduce the environmental burden from such substances and continue active R&D to find alternative technologies and uses for alternative materials.
(1) Lead-free Fuel Tank
Molten lead and alloy plated steel sheeting have been widely used in fuel tanks with approximately 200g of lead per vehicle. Mitsubishi Motors made comprehensive assessments of corrosion resistance, machining performance, fuel tank integrity, and cost. Development is founded on galvanized steel plate consisting of two types of lead-free materials that have the same or better corrosion resistance performance. Almost all of our current production vehicles have been completely switched over to such materials.

(2) Mercury-free Combination Meter
Mercury and cadmium used in the Colt for fluorescent lighting applications is kept to an absolute minimum while a mercury-free LED (Light Emitting Diode) in the combination meter is used as a backlight.
