The construction of ecological civilization is closely related to people's happiness. It is undoubtedly a wise and forward-looking choice to combine the concepts of ecological protection and rational use of resources with civil law, so as to call for more people to spontaneously participate in the protection of the ecological environment. The birth of this basic principle, referred to as the Green Principle, has introduced the concept of "green" into civil law, making it a guideline for all civil activities and private law judgments, and has had a significant impact on the development of the value system of civil law, making the trend of socialization and ecology of Chinese civil law more and more prominent. As a newborn principle, the green principle is interdependent with other basic principles and has the function of making citizens' awareness of environmental protection green and economic development green. It is also necessary for each sub-part of the Civil Code to be connected with the "green principles" and to fully reflect the "green principles" in each sub-part of the Civil Code, so that they can be effectively realized in each sub-part of the Civil Code. "Green Principles Green principles for the traditional civil law theory of innovation, has a deep theoretical basis and important practical value. The significance of the green principle is undeniable, but its application in judicial practice there are still many challenges. Due to the abstract and vague provisions of the green principle in China's legislation, the relevant system in judicial practice is not perfect, and the implementation is difficult, the green principle faces various difficulties in the implementation. At present, there is no clear and unified definition of green principles in China, the connotation is vague, and the lack of supporting rules for the implementation of green principles in the process of application is difficult. In order to break through the dilemma faced by the green principle, the legislation should start from clarifying its connotation, and improve the judicial practice in the direction of moderately limiting the discretion of judges and strengthening case guidance, as well as refining the relevant application standards, improving the public interest litigation system to provide procedural system protection, and striving to establish a unified and coordinated legal system.
