• Air pollution is an environmental problem that can be seen clearly in large communities and in rapid developing areas, where industry, transportation, traffic, and construction are prevalent, as well as in areas where electricity power plant is situated. Air pollutants that are cause of major problems, and that are below the standards include dust and carbon monoxide. Dust is a serious problem especially in crowded communities with traffic congestion, being 3 to 5 times greater than standards. Other pollutants include lead, sulfur dioxide, and nitrogen dioxide. However, their levels remain below Ambient Air Quality Standards.
  
  
• These air pollutants originate from point sources in communities, including vehicles, construction, housing, road construction and maintenance, industries, and business premises. These pollutants not only directly effect human health, but also affect the global environment such as acid rain, global climate change, and acid depletion of the ozone layer.
  
  
• At the present, the government addresses air pollution problems by designating Ambient Air Quality Standards; Emission Standards, Fuel Quality Standards, Lubricant Quality Standards; or promotion of use of unleaded gasoline; installation of smoke filtration equipment in vehicles; examination of pollutants emit from vehicles before extending registration; control of air pollutants from industrial factories by establishing categories of industry subject to air pollution control; and, supplements and revises Industrial Emission Standards. In addition, public campaigns and public relations are undertaken to address air pollution reduction. However, these measures can solve problems, only at one level due to controls, prevention, and solutions to air pollution problems and the lack of unity among many responsible agencies. In addition, cooperation of implementation is inefficient. Agencies that have the duty to monitor and control air pollution emission lack equipment and the personnel with knowledge and experience to take measurements and to establish database systems. Inspection on vehicles and arrestment is insufficient. Research and development of not yet in air pollution, reduction, such as the electric tricycle, electric bus, and electric-motorcycle, are commercial production. Further, a continuing campaign and public relations to change public and vehicles users behavior are lacking.

Goals

1. Air quality in pollution control zones and urban areas, particularly dust, will be within designated Ambient Air Quality Standards. In particular, dust contamination in general areas will have an annual average of not more than 0.1 mg/m3, and dust contamination in roadside areas will have a maximum 24-hour average concentration of not more than 0.3 mg/m3.
2. Other pollutants in ambient air will remain within designated standards, particularly carbon monoxide, beginning in the year 1997.
3. The concentration of air pollutants in industrial zones and general communities, particularly sulfur dioxide and nitrogen oxides, will be within designated standards.

Policy and Implementation Guidelines

Policy

Accelerate the reduction of air pollution initially from vehicles, industry, construction, and transportation. Maintain air quality in areas that have air quality that is within designated standards, not allowing it to be degraded below designated standards. Promote and support utilization of low pollution transportation systems. Promote participation among the government and private sectors and the general public, including polluters and affected people, for the conservation of air quality.

Guidelines

1. Management Guidelines

	Separate industrial zones from communities and residential areas by rigorously implementing master city plans, and prepare reports on the efficiency systems or facilities and equipment for controlling designated air pollutants emission from industries.
	Continuously monitor, check, analyze, and construct database of the overall ambient air quality and emission of air pollutants from its sources.
	Formulate prevention measures and prepare emergency plans for protection, mitigation, suppression or abatement of emergency situations or accidents from air pollution in local areas.
	Assign local government agencies to prepare master plans and action plans for continuous reduction of air pollution in local areas.
	Promote collaboration among government agencies, state enterprises, and the private sector to control and prevent air pollution, and also support efficient and save energy utilization.
	Establish buffer zones around industrial estates and industrial zones in order to control and reduce air pollution conditions arising from industrial activities.
	Control and reduce utilization of substances that are a danger for atmospheric ozone layer.
	Promote investment and use tax measures to promote activities or utilization of facilities and equipment that contribute to mitigating and preventing air pollution.

2.Investment Guidelines

	Promote and support improvement and upgrading of fuel standards to meet international standards, including promotion of ending the use of polluting fuels.
	Support construction of efficient mass transit systems in large urban areas and between the cities; construction of rail systems; and building and improvement of road and express way systems in order to increase surface area available to traffic.
	Upgrade roads passing through all rural villages, and entrance-exit roads in all villages covering a distance of about 1,000 m. from entrance-exit of villages to be asphalt or concrete roads, and support local communities to be able to efficient sweep, vacuum and wash the roads.

3. Legal Guidelines

	Formulate and improve air quality standards, both overall standards and emission standards, including designating methods to check and measure pollution, to be the same as international standards, and strictly enforce these laws against offenders.
	Establish categories of sources of air pollution discharge that must be controlled and odors being discharged to the atmosphere, including formulating appropriate standards for controlling air pollution and odor from sources.
	Designate all categories and ages of vehicles to undertake annual inspections of fuel combustion discharge systems, using an inspection system based on the service center model. Use the symbol "Use Forbidden Temporarily" or, "Use Forbidden Absolutely" for vehicles that cause air pollution beyond designated emission standards establish in the Enhancement and Conservation of National Environmental Quality Act of 1992.
	Formulate orders and regulations of designating standard criteria and guidelines for practice, to control construction and related activities, including the construction of roads, that must be paved, have a shoulder, and have a curb.

4. Supporting Guidelines

	Support and collaborate with the private sector, associations, independent groups and all categories of mass media to participate in public relations efforts and campaigns to educate and increase understanding and awareness of hazardous threats from pollutants in air, and be informed of enforcement of laws against all categories of polluters.
	Support study, research and training in technologies for control and eradication of polluted air, including improving and maintaining machinery to decrease air pollution.
	Promote use of economic incentives to promote solutions to air pollution.
