METRIC EVALUATION FOR COMMUNITY-LEVEL CO₂ REDUCTION THROUGH ENERGY/ENVIRONMENT LEARNING APPROACH

Abstract

 In recent years various environmental programs have been conducted to address climate change. However, CO₂ emission reduction derived from people's behavioral change has rarely been quantitatively-analyzed after programs. In this paper, the community-level energy/environment learning approach and the formulation for metric evaluation were proposed so that household CO₂ reduction as a whole in a community/region can be estimated by accumulating CO₂ emission reduction in a family after energy/environmental learning program has conducted. To estimate, various programs which target individuals from kids to adults were assumed and ranked. Level of cooperation of other household membership, decrease of households continuing saving energy by time, and overestimation caused by participation of other household membership in a different program were also considered. According to a case study in Bunkyo City, Tokyo, in most actions, α of A level program was about 0.2 larger than that of D level. Through programs, α was 0.3 and β was 0.6 approximately on average.
