Abstract

Japan initiated economy-wide material flow studies in 1992 for an evaluation on the quality of the environment, and has since then actively contributed to promote material flow studies at international level. The results of environmental and resource material flow studies including material flow accounting in Japan have contributed to related international activities such as those carried out by the OECD. The current phase of the material flow research projects in Japan aims at developing indicators and methodologies to assess the performance of policy measures and technologies concerning sustainable production and consumption by using material flow models. Material flow indicators are closely related to the Japanese government’s policy as stated in Japan's Basic Plan for Establishing a Sound Material-Cycle Society. As part of the Basic Plan, the Japanese government adopted three numerical time-bound targets on resource efficiency. Those targets is to increase resource productivity to 390,000 yen/ton by 2010 from 280,000 yen/ton in 2000, to increase cyclical use rate to 14% by 2010 from 10% in 2000, and to decrease amount going to final disposal to 28 million tons by 2010 from 56 million tons in 2000. The annual survey on material flow analysis concerning 40 minerals including copper, lead, zinc and gold has been carried out by the JOGMEC(Japan Oil, Gas and Metals National Corporation) in 2005. This survey could provide a clear dataset of domestic material flow for promotion of mineral resource productivity in Japan.

일본은 환경의 질에 관한 평가를 위해 물질흐름 연구를 시작한 이래 국제적으로 물질흐름 연구를 증진하는데 크게 기여하였다. 일본의 물질흐름 계정을 포함한 환경자원 물질흐름 연구의 결과는 OECD에 의해 수행된 것과 같은 국제적 활동에 기여하였다. 현 단계에서 일본 물질흐름 연구 프로젝트들은 물질흐름 모형을 이용해 지속가능한 생산과 소비에 관한 정책이나 기술성과를 평가하기 위한 적정 지표 및 방법론을 개발하는데 있다. 물질흐름 지표들은 건전한 물질순환사회 건설을 위한 기본계획에서 언급한 일본 정부의 정책과 밀접하게 관련되어 있다. 일본 정부의 자원효율성에 관한 세 가지 정량적 달성 목표는 자원생산성을 2000년 280,000 엔/톤에서 2010년 390,000 엔/톤으로 증가시키고, 자원순환사용율은 2000년 10%에서 2010년 14%로 증가시키며, 최종 폐기물 총량은 2000년 56 백만톤에서 2010년 28 백만톤으로 줄이는 것이다. 구리, 연, 아연, 금을 포함한 40개 광종에 관한 2005년도 물질흐름 분석 연차조사는 일본의 광물자원 생산성 향상을 위한 국내 물질흐름의 결과를 제시하고 있다.
