Energy-efficiency labeling, also known as energy efficiency labeling, is an information label attached to energy-consuming products or minimal packaging, the product energy efficiency rating and other performance indicators, the aim is to provide the necessary information for users and consumers' purchasing decisions, to guide and help consumers to choose energy-efficient energy-saving products.

China's energy efficiency labeling system implemented on March 1, 2005 in accordance with the provisions of the Measures, the National Development and Reform Commission, General Administration of Quality Supervision, Inspection and Quarantine and the national commission to develop and publish the catalog of the People's Republic of China on the implementation of energy efficiency labeling ( the first batch), "China's energy efficiency identifies the basic Style," Rules of energy efficiency labeling of household refrigerators and room air regulator energy efficiency identifies the Implementation Rules "(2004 71), since March 2005 1 will be the first of these two products from refrigerators, air conditioners, the implementation of energy efficiency labeling system.
Energy efficiency labeling for the blue and white background, at the top marked with the word "China's energy-efficiency labeling" (CHINA ENERGY LABEL), sticky back, requiring the paste on the front panel of the product. Identifies the structure can be divided into background information bar, the energy efficiency rating display bar display and product-related indicators bar. As an information identifies energy-efficiency labeling visually express the product's energy efficiency rating, energy consumption indicators can and other important performance indicators, and energy efficiency rating is the most important indicators to determine whether the product is energy-saving, energy efficiency rating of the product the lower, indicating higher energy efficiency, the better the energy saving effect, the more power. At present, China's energy-efficiency labeling of energy efficiency is divided into 1, 2, 3, 4, 5 a total of five levels, Level 1 means that the products reach the international advanced level, the most energy-saving, that is the lowest energy consumption; Level 2 Comparison of energy-saving; Level 3 the product of the energy efficiency of the average level of China's market; Level 4 product energy efficiency is lower than the market average; Level 5 is the market access indicators, below the grade requirements do not allow the production and sale. Universal awareness of energy efficiency in the various consumer groups, bar with three kinds of manifestations of the energy efficiency rating show to visualize the expression of the energy efficiency rating information: First, the text of the "low-energy, medium, high energy consumption; the second is digital part of the "1,2,3,4,5"; three colors represent the level of emotional arrangements indicate the color in which red represents prohibition, orange on behalf of the warning, green for environmental protection and energy saving.
Thus the efficiency labeling so that consumers can compare the energy saving effect of the different products, so that consumers can buy more energy efficient, cheaper products.
Mandatory implementation of energy efficiency in China: monitor, LCD TV, plasma TV, rice cookers, induction cooker, household washing machines, refrigerators, water heaters, energy saving lamps, high pressure sodium lamp, printer, copier, electric fans.

The energy efficiency rating is divided into five levels:
At present more than 100 countries around the world have implemented energy-efficiency labeling system. Color-coded blue and white background, divided into 1, 2, 3, 4, 5 a total offive levels, Level 1 means that the products reach the international advanced level, the most energy-saving, that is the lowest energy consumption; Level 2 Comparison of energy-saving;rating 3 indicates the energy efficiency of products for the average level of China's market; level 4 product energy efficiency is lower than the market average; level 5 is the market access indicators, below the grade requirements do not allow the production and sale. Energy-efficiency labeling back sticky at the top marked with the words "China's energy-efficiency labeling" (CHINA ENERGY LABEL) color labels, usually pasted on the front panel of the product.
