To promote green buildings is the way access to the sustainable development. Currently, China has issued some regulations and systems to boost the green building. However, problems lie in China and the systems are not effective. USA and EU have rich experiences and fairly sophisticated legislation and policies to develop green building. China may get some lessens from these countries. This paper will make an overview of legal framework and main system of green building in China, then, analyses some important legal systems and typical case related green building in the USA and EU. Further, problems were pointed out in the China based on the comparative analysis of these countries. Lastly, according to the condition in China and lessons from USA and EU, this paper will put some suggests to promote green building, such as, take some measures to enhance the awareness of the stakeholders, create multi- incentive tools and so on.展开更多
