Japanese energy efficiency standards program for appliances is a unique program which sets and revises mandatory standards based on the products of the highest energy efficiency on the markets. This study assessed the cost-effectiveness of the standard settings for air conditioner as a major residential appliance or typical example in the program. Based on analyses of empirical data, the net costs and effects from 1999 to 2040 were estimated. When applying a discount rate of 3%, the cost of abating CO2 emissions realized through the considered standards was estimated to be -13700 JPY/t-CO2. The sensitivity analysis, however, showed the cost turns into positive at a discount rate of 26% or higher.
