One of the best solutions for both issues is to improve energy efficiency. To improve energy efficiency, it is commonly recognized by both standards and energy sectors that Minimum Energy Performance Standards （MEPS） could play an important role . China and the USA, the top two energy consumption countries in the world, both have adopted MEPS program to address the problem of energy conservation and environmental protection. This paper analyzes and compares the two countries＇ MEPS programs from a historical and legal context, examining the role of different stakeholders in the process,the process, the outcomes by standards,and then makes some recommendations for both sides.展开更多
