Assessments of Japanese Energy Efficiency Policy Measures in Residential Sector

Abstract

Eco-point program was one of the key programs intended for improvement in energy efficiency in residential sector in Japan. This paper estimated energy saving and CO₂ emission reduction effects of the program considering its impacts on changes in sales demand of appliances together with the expected energy efficiency improvements after the program. The estimated total effect of CO₂ reduction through the Eco-point program for air conditioners, refrigerators and televisions was 0.94 Mt-CO₂. The effect was much smaller than that estimated by the Japanese government. For the key aspect in the program for TVs, sensitivity analysis was also performed.
