Research on the key issues of promoting policy environmental assessment

Policy environmental assessment is an institutional tool to analyze and predict the environmental impacts of proposed policies in advance and put forward necessary measures to optimize the environmental benefits of the policies. China already has provisions and requirements for policy environmental assessment in the Environmental Protection Law of the People's Republic of China and other relevant laws, regulations and documents, but some problems are still existing, such as non-uniform evaluation objects, unclear evaluation targets and inconsistent evaluation contents. By carrying out the eco-environmental impact assessment of economic and technological policies, economic assessment of environmental policies, review of policy legitimacy, post-legislative assessment and planning implementation assessment, China has accumulated some experience in policy environmental assessment, but there are still some factors that hinder the further promotion of policy environmental assessment. Therefore, it was proposed that policy-making and implementation departments should be policy environmental assessment subjects, the objects of policy environmental assessment could be defined through the combination of classifying + screening process, the policy environmental assessment and comprehensive assessment, pre-assessment and post-assessment should be integrated, and policy-making and implementation departments should be encouraged to take the initiative to carry out policy environmental assessment.
