    Accelerating promotion of LEVs

Number of LEVs owned increased from approximately 630,000 units at the end of FY2000 to approximately 9.68 million units at the end of FY2004. With this, the target stipulated in the plan is expected to be achieved ahead of the targeted time frame.

3. Trend and emerging issues Promotion of LEVs is considered to have accelerated due to the government’s initiative in the replacement of official vehicles and introduction of greening of automobile tax. In order to further accomplish popularization of LEVs, it might be necessary to review the action plan.

4. Constraints and challenge GoJ is aiming at promoting total of 50,000 fuel cell vehicles (FCVs) by FY 2010. In June 2005, type approval for FCVs was conducted for the first time in the world. However, current status of promotion has not been advanced due to number of issues such as cost.

? Transboundary air pollution Decision-Making



Acid deposition Acid precipitation is a growing concern in Japan, and the contribution of transboundary air pollution to this phenomenon is increasing in importance. The average of the rain and snow pH at each monitoring site throughout the whole period (20 years) ranged from pH 4.49 (Ijira Lake) to pH 5.85 (Ube), while the overall average

was pH 4.77. to plants, was

Rain and snow with a pH of less than 3, which may cause acute damage not observed. However, studies carried out from JFY 2000 to JFY 2002

indicated that about 5% of samples had throughout Japan is classified as acidic, measured in areas of Europe and North

a pH of less than 4. Thus, precipitation and presents pH levels similar to those America where acidification damage has

occurred. Sulfate and nitrate deposition varied with season. The maximum in winter on the Japan Sea side of the main island of Japan. In area, the supply of sulfur and nitrogen oxides is considered

atmosphere in winter, suggesting that pollutants may originate from the Continent. A nationwide increase in ozone concentration was observed in spring, and the



trend was observed strongly suspected. At present, there is
