Proposal of Household Economy- Environment Accounts by Household Type 13 th AIM International Workshop @ NIES, Japan Feb 16-18, 2008 National Institute for Environmental Studies Yuko Kanamori
Backgrounds and Objective ・ The household sector is an important component of any investigation of future environmental impacts because households are an end consumer and lifestyle changes have a major influence on society. ・ In the household sector, however, concrete approaches including technical improvements and construction of environment-friendly systems are not so effective because there are few practical restrictions motivating households to take immediate action even when targets are formulated. ・ Under such circumstances, it is essential to quantitatively understand the impacts that lifestyle changes have on the environment in order to select more effective environment-friendly actions. ・ We propose household economy-environment accounts as a tool for analyzing lifestyles. ・ These accounts make it possible to evaluate the environmental impact of lifestyle changes.
