Guidelines for developing emission inventory in East Asia
This guidebook is expected to be used for preparation of detailed and reliable emission inventory in East Asia, and is expected to be used to establish strategy for anti-pollution measures in specific location, country or in East Asia.
In East Asian region, the rapid economic growth is causing emission increase of substances responsible for acid rain such as sulfur dioxide (SO2) and nitrogen oxide (NOx), and volatile organic compounds (VOC), leading to concerns of its environmental impact. Also tropospheric ozone has attracted attention as long range trans-boundary air pollutant, and there has been reports on its density increase, effects on plants, and its reaction with VOC in the air which react to form photochemical oxidants.
This serious condition of air pollution following economic growth will interfere with the continuous development of East Asian countries. This condition will effect to increase the background level of long range trans-boundary air pollution on Japan as well as on a global scale. In addition, the large scale emission source is also a cause of large amount of greenhouse gases.
However, in East Asian region, the organization of basic information necessary to manage atmospheric environment, is insufficient. In relation to this, it is difficult to formulate effective anti-pollutant measure based on scientific knowledge, including knowledge of reduction of anti-pollutant measure to its goal, reduction potential and methods of countermeasures.
