Currently,private environmental governance has become an increasingly important aspect of environmental law and policy,providing new methods for addressing environmental issues.However,its conceptual independence and functional effectiveness still require discussion.Conceptually,private environmental governance refers to a series of actions taken by non-governmental entities to achieve goals traditionally pursued by governments,mainly including the establishment of collective standards and market activities aimed at improving environmental outcomes.Functionally,private environmental governance adjusts corporate environmental behavior through industry self-regulation,influencing corporate performance,or reducing auditing costs.Additionally,private environmental governance in forest and fisheries sectors has been observed to indirectly affect environmental quality.To some extent,private environmental governance fills the gaps left by public governance,especially during periods of legislative stagnation,serving a supplementary function.In the realms of global environmental governance and in areas where various levels of government require separate legislation,private environmental governance has proven effective in coordinating corporate actions and mitigating environmental risks,highlighting a promising development outlook.
