Sustainability

At Mitsubishi, we take our environmental commitment very seriously.

We recognise that our vehicles impact on the environment in various forms as they go through their lifecycle of production, use and recycling. For this reason, we are committed to reducing our environmental impact in the following key areas: 

Improving our Environmental Management - by:

  • Designing more environmentally sound and sustainable vehicles.
  • Obtaining ISO Certification for our planning and development activity.
  • Training our employees, publishing email magazines and hosting educational sessions to ensure all stakeholders are informed and aware.  
  • Periodically auditing our facilities and completing resource recovery operations.
  • Improving our communication regarding environmental issues with the general public and communities in which we operate.

Preventing Global Warming & Environmental Pollution - by:

  • Improving our fuel economy and reducing vehicle emissions.
  • Utilising refrigerant, conservation-type air conditioners in all new vehicles.
  • Conducting target-based activities to reduce our use of electricity, fuel and other types of energy.
  • Developing low-emission vehicles, including investigating an electric vehicle that emits no carbon dioxide.
  • Taking steps to make the cabins of our vehicles more comfortable and safer by reducing emissions and utilising bio-clear filters.
  • Requiring all suppliers follow our management of hazardous substances guidelines and disclosing data on their use.
  • Complying with industry and environmental regulations regarding air, water, noise and vibration.
  • Running awareness campaigns promoting ‘eco driving’.
  • Collecting chlorofluorocarbons and disposing of them in an environmentally responsible manner.

Recycling and Resource Conservation - by:

  • Promoting reuse and recycling wherever possible.
  • Endeavoring to maintain a zero-volume final disposal record by reducing the volume of waste generated and converting from thermal recycling to material recycling.
  • Promoting the return of packaging - by designing racks and shipping boxes that can be compressed from one-third to one-tenth their size after delivery.
  • Collecting and disposing of used polypropylene bumpers and airbags.
  • Finely separating and storing the large volume of waste generated during maintenance and repairs. Much of this material is then sold as scrap metal or for other purposes.

Technology to prevent Global Warming

At Mitsubishi Motors, we understand the movement to break away from fossil fuels. That’s why we’re developing a range of innovative systems designed to ensure our vehicles run better and cleaner.

Next-generation Clean Diesel Engines:

The excellent fuel efficiency of diesel engines means they improve fuel consumption by 20-30% compared to petrol engines.

Exhaust gasses can be a problem for diesel engines, which is why MMC is promoting the development of new, clean, diesel engine technology.

These engines will aim to produce the same level of emissions generated by petrol engines while using less fuel.

The new clean diesel engine already meets the standards imposed by EURO5, Europe’s next-generation emissions regulations, and the next step is to market the engine in North America and Japan. MMC will continue to aim for top output and fuel efficiency in diesel engines.

Development of Bio-ethanol Fuel-compatible Vehicles:

Bio-ethanol fuel, which is produced from plants that absorb CO2 in the atmosphere as they grow, has been designated as a zero-emission or ‘carbon-neutral’ fuel by the Kyoto Protocol-based method of calculating carbon dioxide emissions.

Mitsubishi Motors is developing flexible fuel vehicles (FFVs) that can run on petrol, bio-ethanol, and fuels that combine the two. In 2007, we launched our first FFVs into the Brazilian market.

The FFV system achieves optimal fuel combustion by estimating the ratio of bio-ethanol in the fuel based on the output of an exhaust gas density sensor fitted in the exhaust system. As a result, the engine can handle petrol-ethanol mixes with proportions of ethanol from 0% to 100% while achieving performance and exhaust emissions on par with petrol vehicles.

Development of the Twin Clutch SST - A Next-generation High-efficiency Transmission

The Twin Clutch Sports Shift Transmission is a high-efficiency transmission developed by MMC. It combines the sportiness and fuel efficiency of a manual transmission with the convenience of an automatic. Mitsubishi plans to fit the Twin Clutch SST to new high-performance sports sedans.

Improving Petrol Engine Efficiency

MMC has promoted innovations in our passenger car petrol engine line-up since 2004. We aim to pair our common design concepts with features such as high performance, low fuel consumption, lower exhaust emissions, and lighter, more compact engines. In 2006, we launched the 3.0L MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) engine in the new Outlander.

This new engine series delivers a high level of performance, including top-class maximum power output and maximum torque, through the MIVEC system. It is also paired with an aluminium cylinder block to make it lighter and more fuel-efficient than conventional engines.

Reduction in Power Consumption of Automotive Air Conditioning

MMC understands that reducing the power consumed by automotive air conditioning helps to improve fuel efficiency and reduce CO2 emissions. The new Power-saving Automotive Air Conditioning Unit that we have developed in conjunction with Mitsubishi Heavy Industries won the US Environmental Protection Agency Climate Protection Award in 2007 for achieving a reduction in power usage.

Green Plastic

MMC is in the process of developing a plant-based resin with broad practical applications. As it is a carbon-neutral material, it not only preserves petroleum resources, but also reduced CO2 emissions. We are currently exploring its uses in producing car interior components.

Protecting and rehabilitating vegetation

As the concerns about global climate change increase, MMC has become involved in protecting and rehabilitating areas of vegetation around the world. We are currently working on projects in Japan, the United States and Australia.

Pajero Forest

The Pajero Forest covers over three hectares of mountain woodlands in Japan. MMC has launched an initiative to conserve and cultivate this area for at least seven years, dating from June 2007. We will be joining the local community in tree-planting and other activities to ensure that the forest continues to flourish.

On June 14, 2007, Mitsubishi held opened the Pajero Forest and Local Mountain Restoration Initiative with a ceremony, in which Mitsubishi Motors President Osamu Masuko and local officials planted trees to mark the occasion.

North American Prairie Restoration Project

Since 1999, Mitsubishi Motors North America Inc. has promoted prairie restoration activities through participation in the Illinois Department of Natural Resources’ Prairie Restoration Project. Involving the cultivation of warm season wild grasses and 26 types of wildflowers, the project covers 3.9 acres around the MMNA factory, and has resulted in natural prairie in the surrounding region being substantially restored.

Environmental Conservation Activities in Australia

In 2006, Mitsubishi Motors Australia Ltd. in conjunction with the Australian Carbon Biosequestration Initiative held an event to plant enough trees to cover the carbon emissions generated by the Mitsubishi cars owned by the South Australian State Government. MMAL workers and volunteers planted over 7000 trees, resulting in 22 hectares of land becoming forest.
