the difficulty in identifying core element, taking Shandong renewable energy policy as a case, the ap⁃plication of the combined tool of life cycle assessment (LCA) and scenario analysis in the environmen⁃tal impact assessment of renewable energy policy were discussed. The results showed that the combina⁃tion of LCA and scenario analysis tools could reduce the uncertainty of renewable energy policy EIA andimprove the decision-making ability when comparing and selecting optimization schemes. In order to a⁃chieve the consistency between policy implementation and EIA, it was necessary to conduct the follow-up evaluation based on policy EIA.
