Abstract: The article 67 of the Tort Liability Law of the PRC is used to decide the share of several persons environmental tort liability. There are four types of several persons environmental tort liability according to chapter two of the tort liability law of the PRC, namely, joint infringement, joint risk, concurrence of causality and common causal relationship. The article 67 is used to determine the share of internal responsibility size in related liabilities and it is also used to determine the share of the responsibility in coownership liabilities. However the article 67 has a limited role when it comes to decide tort liability, and it is easy to cause misunderstanding, so the article 67 should be deleted.

Key words: several persons environmental tort, related liability, coownership liability, rules used to determine the share of responsibility

摘要： 《侵权责任法》第67条是确定数个污染者责任份额大小的规则。责任类型需要根据第二章数人侵权规则来具体认定，可能成立共同侵权、共同危险、分别侵权承担连带责任和分别侵权承担按份责任四种情形。在连带责任中，第67条用于确定连带责任人内部责任份额的大小；在按份责任中，第67条适用于确定责任人责任份额大小的依据。第67条所起作用有限，且极易引起误解，建议未来立法中宜将第67条删去。
