Environmental issues such as industrial pollution, excessive packaging, light pollution, and rubbish pollution in households are all growing at an alarming rate with the rapid expansion of the economy. It is necessary for government departments and the judiciary to work together to resolve issues that are brought on by the environment. There has been a progressive development of a variety of mechanisms for the resolution of environmental conflicts; nevertheless, these mechanisms are still unable to fulfill all of the requirements that the public has for the resolution of environmental disputes, and a significant percentage of disputes cannot be resolved on time. The Chinese government has investigated alternative dispute resolution (ADR), established professional mediation institutions and social organizations as neutral third parties to intervene in environmental disputes, and provided reasonable solutions based on local policies and specific disputes through full understanding of issues. As a result, the Chinese government has achieved remarkable results. This article examines the pros and cons of using third-party mediation in the process of resolving environmental disputes and makes comparisons between the traditional method of resolving environmental disputes and third-party mediation as a method for resolving environmental disputes. The article uses statistical correlation methods to analyze the role of third-party mediation in natural environmental pollution control issues in various countries. Based on the analysis results, suggestions are put forward to improve the third-party mediation system of environmental disputes in our country. Experimental results show that the mediation system can promote information sharing, strengthen social cooperation and encourage all parties to take more coordinated actions in environmental protection, thereby promoting sustainable development and the realization of an ecological balance.
