This paper uses comparison and logical methods to discuss Chapter 4 of Energy Law (Draft for Soliciting Opinions). Energy development is taken as a separate chapter; in-situ energy conversion is added to energy processing and conversion, common features are summarized to form general provisions and other provisions. According to respective characteristics of system for total amount control of energy development, performance guarantee system, environmental trust fund system, energy retaining system and environmental lien system, incorporate them into energy development, in-situ energy conversion and energy processing and conversion, in the hope of solving China's shortage of supply for environmental protection laws on energy development and in-situ conversion, responding to times of environmental protection, and optimizing China's Energy Law.展开更多

In this regard,on June 24,the Standing Committee of National People's Congress deliberated the draft of Energy Saving Law,according to which China is to take"resources saving"as a basic national policy.This is a key issue to the long-term benefits of China.With relevant questions,China's Foreign Trade interviewed Dr, Yonglong L(?),Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).and Research Professor at the Chinese Academy of Sciences. Let's listen to Dr.L(?)'s comments with wisdom.展开更多

For the pollution problem in China’s textile and garment industry, the author particularly analyzes the pollution of the textile and garment industry mainly occurred in the process of textile and clothing production and sales in this article. Finally, the author puts forward detail measure to control the pollution from the two aspects and advocates the concept of low-carbon environmental protection and green lifestyle. The low-carbon environmental protection has become a phenomenon in Textile and Apparel.展开更多
