Air pollution

Air pollution refers to contamination of the air by harmful substances generated mainly through incineration. In the field of transportation, the main problems are the carbon monoxide, nitrogen oxides, and sulfur oxides contained in car exhaust. Problems related to air pollution began to surface in the 1960s, behind enormous waves of motorization. Japan has countered the problems with Air Pollution Control Law and other legislation regulating exhaust gases. Another air pollution problem that has attracted attention in recent years is global warming. The transportation sector accounts for approximately 20% of Japans emission of carbon dioxide, the substance most blamed for global warming. The government is being pressured intensely to take measures to reduce CO2 emissions.

 

Exhaust gas regulations

One of environmental regulations setting standards for the emission of substances which cause air pollution and global warming. Japan has implemented many regulations related to automobile exhaust, which is the main source of such emissions. A recent example is the revised safety regulations for vehicles issued March 1997, which introduced measures to cut carbon monoxide and carbon hydride emissions, based on recommendations by the Central Council for Environmental Pollution Control and the Central Environment Council. As a more fundamental approach, the government is simultaneously promoting the introduction of electric cars, hybrid cars and other low-pollution vehicles. Though the popularity of low-pollution cars remains low, their use is on the rise, aided by technological innovation and various incentives.
