The government has now launched a programme to ensure that by 2015, 20% of all new buildings will meet new higher efficiency standards. In 2005, the government introduced an energy efficiency labelling system for air-conditioners and refrigerators which has since been broadened to cover a larger range of goods and modified to incorporate some mandatory standards. More recently the government banned the sale of 100-watt or greater incandescent light bulbs (NDRC, 2012). The two leading schemes in China are the Three Star system developed by the MHRUD and the Leadership in Energy and Environmental Design system, which originated in the United States.
