This paper focuses on the research methods and steps involved in carrying out studies on different types of carbon footprints. Furthermore, a comparative study of different carbon footprint assessment standards was carried out to identify their similarities, differences and deficiencies. Goals, principles, research boundaries, calculation methods, data selection and other aspects of organizations footprint and product carbon footprint were analysed, respectively. Organizations carbon footprint assessment standards—ISO14064 and Greenhouse Gas (GHG) protocol and product carbon footprint assessment standards—PAS2050, TSQ0010, ISO14047 and Product and Supply Chain GHG Protocol were analysed comparatively. The selection of GHG, system settings, quantification and carbon footprint, selection of date and treatment of specific emissions are the most important part of the study of the carbon footprint and assessment standards, especially for organizations and products. Guidelines had been made on these issues from existing assessment standards, but further improvement is still needed.

Based on analysis of the reasons of low efficiency in construction industry, the paper suggests that the key point of improving efficiency is the implementation of lifecycle building information integrated management. The main contents of research in this paper include the concept of BIM, product analysis and implementation. After the analysis of the BLM�» it is indiFated that BIM is the key technology in the implementation of BLM; And analysis of concept, Characteristics and product of BIM from the construction project lifecycle perspective ,finally discusses the obstacles in the applications of BIM in our country. And the path to solve, hoping to cause more people concerned about the BIM technology, and to provide references of BIM technology research and practicing in China.
