Targetl 3.9

Basic Approach
Vehicles are products that can affect human healthand biodiversity through the emission of environmental pollutants and chemical substances during business activities or product use.
MITSUBISHI MOTORS aims to contribute to therealization of a pollution-free society and has positioned it as one of the key challenges in its Environmental Plan Package. We are working to reduce theenvironmental impact of our products and the pollution resulting from our business activities.
In the stage of product development, along with
reducing noxious components of exhaust gases andpromoting the development of fuel economy improving technologies and electrification technologies, we
strive to manage hazardous substances. In production
processes, we are endeavoring to reduce air pollutants emitted from out plants by voluntarily enacting
activity standards that are stricter than legal requirements. In order to reduce the impact on the environment from air pollutants and chemical substances,
we engage in the prevention of pollution throughout
all our business activities.

Improving Gasoline Engine Vehicles
In the 1960s, emissions of carbon monoxide (CO),hydrocarbons (HC) and nitrogen oxides (NOx) wererestricted by regulations, and those restrictions have
gradually been tightened since.
We have taken various measures since such regulations were first introduced. Currently, our products
are compliant with strict emission regulations, thanks
to the advanced technologies such as electronicallycontrolled fuel injectors for combustion control, gasoline particulate filter (GPF) systems, and improved
catalyst technologies.

Improving Diesel Engine Vehicles
For diesel engine vehicles, emissions of CO, HC, NOx,and particulate matter (PM) *2 have been regulated
in some countries and regions, such as Japan, UnitedStates and European countries, since the 1970s.
Since such regulations were first introduced, we
have taken measures including improving the combustion technology. To comply with these regulations,
we have developed and produced clean diesel engines
by systemizing combustion control technologies suchas variable geometry turbocharger and high pressure
fuel injection system, as well as after-treatment technologies such as NOx trap catalyst, diesel particulate

filter, and urea selective catalytic reduction system.

In addition to developing and popularizing electrified
vehicles, which emit little exhaust while driving, weare endeavoring to develop and improve gasoline anddiesel vehicles that emit fewer hazardous substances.
