In this case, when such measures are to be implemented for the global environmental conservation, Japan will consider international collaboration so as to appropriately ensure the effectiveness of such measures. As regards the costs for the collection and disposal of general waste, in addition to controlling the discharge of waste by requiring households to assume an appropriate share of these costs, Japan will study measures to create and promote conditions for adopting a deposit system. Also, Japan will conduct wide-ranging studies on the application of economic measures, including studies on arrangements to clarify the responsibilities of those who discharge the waste and to appropriately reflect the costs of waste collection and disposal on product prices. For this purpose, it will attach importance to the implementation of the following activities. It is also indicated in the current Five-Year Economic Plan that the development of such indicator system will be promoted.
Specific activities are as follows.
As regards the SEEA to be included in the SNA, according to a three-year plan which began in FY 1992, Japan will continue to promote study on accounting structure and methods of monetary evaluation of the environment and will conduct the design of and trial calculations for the SEEA of Japan. Steps will be taken to move to estimations for the next stage, according to the level of achievement of the above-mentioned trial calculation. As regards environmental resource accounting, giving due considera-tion to the international impact, Japan will develop methodologies for drawing up physical accounting tables reflecting the relevance between the environmental loads by Japan's economic activities and the quantitative and qualitative changes in environmental and natural resources, as well as methodologies for evaluating those changes in terms of economic value. It will also improve the information system about them.
