The ACEEE 2012 International Energy Efficiency Scorecard will rank 12 of the world's largest economies representing over 78 percent of global gross domestic product, 63 percent of global energy consumption, and 62 percent of the global carbon-dioxide-equivalent emissions.
The rankings will include: Australia, Brazil, Canada, China, France, Germany, Italy, Japan, Russia, the United Kingdom, the United States, and the European Union. Over 25 different energy efficiency indicators or "metrics" have been analyzed for each economy ranked in the report. The rankings are determined by a total score out of 100 possible points.
Points can be earned in four difference categories including buildings, industry, and transportation, as well as metrics that track cross-cutting aspects of energy use at the national level.
