For a Safe and Refreshing Environment

 Environmental Management Bureau is committed to preventing air pollution due to the emissions of factories, cars, and the like, preventing pollution due to dioxins, and protecting the health of the Japanese people, as well as preserving our living environment by tacking such issues as noise, vibration, and offensive odors.

■Measures to prevent air pollution from  factories and industrial facilities
  (stationary sources)
 In order to prevent air pollution by soot and smoke from factories and industrial facilities, the bureau regulates emissions in accordance with the Air Pollution Control Law and other statutes, and monitoring of air pollution. There is also pollution prevention organization in factories (pollution control managers).

■Measures against automotive pollution (mobile sources)
 In order to prevent air pollution due to nitrogen oxide (NOx), particulate matter (PM), and other substances contained in automotive exhaust, and prevent noise pollution, the bureau regulates emissions of individual automobiles, as well as noise and fuel quality. In major cities with heavy road traffic where air pollution from nitrogen oxide and particulate matter is particularly severe, there are also special emissions regulations for nitrogen oxide and particulate matter in accordance with the Automobile NOx/PM Reduction Law, as well as measures to coordinate and reduce transportation demand and prevent traffic jams. The bureau also offers subsidy programs, tax incentives, and other measures to encourage the wider use of low-emission vehicles and other automobiles with better emissions performance.

The Ministry of the Environment has been operating the Atmospheric Environmental Regional Observation System since 1999. This system makes it possible to check air quality conditions in real time. For details

State of Heat Island Phenomenon

In the vicinity of Koshigaya
in Saitama prefecture, there were over 200
cumulative hours over 30。C
in 1981, but over 400 in 1999.

Measures against Vehicle Exhaust Emissions

 Japan has the worldユs strictest exhaust-emission regulations for diesel vehicles, and has played a pioneering role in environmental measures worldwide. On the fuel side, is also phasing out the sulfur content of diesel fuel.
The Cabinet has also adopted the Fundamental Policy for Reducing Total Emissions based on the Automobile NOx/PM Law. It sets targets for nitrogen oxide and particulate matter, including overall achievement of environmental standards by FY 2010.

■Dioxin Measures
 Japan is pushing forward a comprehensive set of measures against environmental pollution from dioxins, including measures to reduce dioxin emissions based on the Law Concerning Special Measures against Dioxins.
Environmental Management Bureau regulates dioxin emissions by factories and industrial facilities and regularly observes environmental conditions. It also collects information on air, water, and soil pollution and the like in order to enforce comprehensive measures against dioxins.

■Measures to Conserve
 the Living Environment

 In order to prevent noise, vibration, and offensive odors that degrade the living environment, the bureau regulates factories and industrial facilities in accordance with the Noise Regulation Law, Vibration Regulation Law, and Offensive Odor Control Law. The bureau also tackles such issues as low-frequency noise, heat islands, and light pollution.

■Other Activities
  The bureau monitors the strength of radioactive rays and the quality of radioactive substances in the environment in cooperation with the Ministry of Education, Culture, Sports,Science and Technology.
