Theglobal spreadof automobileshas totally surpassed the imaginationof
theearlydaysandhasgivenrisetonewissuesintheformofenvironmental
concerns. In the 1960s, exhaust gas regulations were first established in
California and Japan, and from this emerged the development of various
environmental technologies by automobile manufacturers striving to
satisfy these regulations. Today, automobile manufacturers are expected
not only tomake continuous efforts to eliminate harmful substances from
exhaust gas in order to prevent air pollution, but to also minimize the
emission of carbon dioxide, which is a principal greenhouse effect gas.
Thesemodern countermeasures have also had the effect of reducing fuel
consumption and generating advantages for the consumer.

Fuel economy standard (km/L)

Source: The graph represents a simple conversion of the fuel standard in each country from
the International Council on Clean Transportation. When a correction is applied by a simple
calculation to account for a fuel consumption measurement mode, taking into account
deregulationmeasures and differences in vehicle types, the fuel standard for the EUbecomes
21.1 km/L (2021 reference value is calculated by METI), and for the U.S. it becomes 16.5 km/L
(2020 reference value calculated by METI). The 2010-2015 values for Japan have been added
by METI (they are reference values, as themeasurement mode differs from2015).
