Food waste remains a critical issue in Japan, especially in light of the country's low food self-sufficiency rate and shortage of available landfill sites for waste disposal. In order to evaluate options for further preventing and mitigating food waste in Japan, we analyzed food waste trends by estimating the disparity between calorie/protein...

The indicators measure elements of SEPLS resilience that are, almost by definition, strongly interrelated. The practices and institutions that they describe can be grouped in five areas: • Landscape/seascape diversity and ecosystem protection • Biodiversity (including agricultural biodiversity) • Knowledge and innovation • Governance and social...

We estimate the time-series environmental impact of material use which will be utilised to estimate eco-efficiency (GDP/environmental impact of material use) in Japan for identified 120 materials in four categories (fossil resources, non-metallic minerals, metals and biomass) by estimating the per unit of environmental impacts in resources...

本稿では、欧州を中心とした国際的な資源効率・循環経済の政策動向について、特にEUにおいて持続可能な資源管理・資源効率・循環経済の政策発展が進む中で、経済と環境の政策統合、物質資源効率と低炭素政策の調和がはかられてきた経緯を示し、その内容を分析しつつ、わが国の資源効率政策の今後の方向性について議論している。The paper discusses that environment and social economic policy have been integrated especially in Europe.

In order to develop strategies for changing the future, this literature has developed various theories of change, based on some analysis of the past, but mostly...

IGES made a proposal of an MRV methodology for the JCM projects which installs solar PV systems to the JCM Joint Committee between Mongolia and Japan. The Joint Committee approved a methodology MN_AM003 "Installation of Solar PV System" on the basis of this proposal. The attached proposed version (PM_003) includes three documents: the JCM Proposed...

The author explained about the roles of hydropower in ensuring the energy security in the Mekong region. Based on a critical review of the current trend of hydropower development, it argued that existing approach of uncoordinated Mekong mainstream hydropower development cannot ensure sustainable development; rather it causes negative impacts on...

Assuming all thermal power plants currently planned for construction and replacement are put into operation, coal-fired and gas-fired power plants need to operate below 56% and 43%, respectively, of their capacity factor in order to achieve Japan’s electric power sector’s voluntary emissions intensity targets for 2030. However, the voluntary...
