The current research paper examines the basis of civil liability for environmental damage in Jordanian legislation. The methodology involves using the descriptive and analytical research approach as it is appropriate for the nature of the current research study. The research results confirm that the Environmental Protection Law and the related regulations issued lack a clear basis and explicit text regarding liability. Given the said results, the research discusses the adequacy of general rules in filling this legislative gap and details the most important legal bases in civil law, demonstrating methods to address this issue. On the other hand, the research deals with international civil liability for environmental damage and the agreements related to the subject, and the extent of the impact of these agreements on national legislation.
