This summary report provides an overview of the impact that standards and labelling programmes are having on the energy efficiency of energy-using appliances and equipment in countries around the world. It draws on a global review of nearly 400 published reports, studies and papers covering more than 100 products – representing one of the most comprehensive datasets assembled on the topic to date. It confirms that improvements to the energy efficiency of appliances and equipment are some of the lowest-cost options available today for reducing energy consumption and associated emissions, with typical society benefit/cost ratios of 4:1. Programmes that have been operating the longest, such as those in the United States and the European Union, are estimated to deliver annual reductions of around 15% of total current electricity consumption. These programmes provide net financial benefits to individuals and the community. Other benefits, including employment, product innovation, water savings, improvements in air quality and the reduction of public expenditure on health, add to the case for stronger standards and labels.
