The challenges of environmental algorithmic decision-making include not only environmental risks and data risks,but also the defects of the original environmental governance paradigm.The resulting risk generalization and security and privacy issues cannot be dealt with by the individual empowerment paradigm and crisis-response environmental law.After comprehensive use of normative analysis,value analysis and other methods,it is found that environmental algorithmic decision-making and traditional environmental legal regulatory tools coexist interdependently.The instrumental rationality of environmental algorithms needs to be regulated by the value rationality of environmental law.It is imperative to regulate environmental algorithmic decision-making with environmental law.Based on the experience of comparative law,my country's environmental law needs to be adapted and adjusted,delineate the applicable boundaries of the coordination of algorithmic impact assessment and environmental impact assessment,and clarify the public participation procedure guarantee for risk classification.Establish a decision-making model based on the formal judgment of the"red light"rule and the substantive judgment of the"yellow light"standard to improve the effectiveness of environmental algorithms.
