Projected Impacts of Global Energy Efficiency Standards for Appliances Implemented in SEAD Countries Since 2010

The adoption of increasingly stringent energy efficiency standards for appliances is an established and effective method of reducing energy use and global greenhouse gas emissions. In this study, we present and analyze, using a bottom-up analytical framework, appliance efficiency standards for a number of end uses in countries participating in the Super-efficient Equipment and Appliance Deployment (SEAD) initiative. SEAD member countries account for about one half of global energy consumption. The study summarizes minimum performance standards (MEPS) that were implemented, announced, or are being considered since January 2010. The impact of these standards is analyzed using the Bottom-Up Energy Analysis System (BUENAS). BUENAS integrates activity forecasting, unit energy consumption, and stock accounting in order to project energy consumption at a more detailed level than other forecasting models, especially those that are top-down in nature. The analytical framework underpinning BUENAS is briefly described and the model is used to project the energy and emissions savings potential of the MEPS through the year 2030. The standards analyzed are expected to save almost 660 TWh of energy in 2030, and result in cumulative emissions savings of 3.3 gigatons (Gt) of CO2 from 2010 to 2030, a reduction of 4% and 3% respectively from a scenario without standards.
