Abstract: Under the new situation of global climate governance,the Paris agreement proposes in article 15 to establish a compliance mechanism that can promote compliance and enable countries to abide by their emission reduction commitments. The core of this compliance mechanism is to establish non-compliance procedures for parties that fail to fulfill their emission reduction commitments. However,the non-compliance procedure under the emission reduction commitment is a promotion and non-punitive compliance safeguard procedure,and the parties have not reached consensus on the formulation of the procedure. There are many difficulties in dealing with the relationship between non-compliance procedures and mandatory elements of treaties,how non-compliance embodies the principle of common but differentiated responsibilities,and its relationship with the rules of transparency and the global inventory mechanism. In order to build a procedure rule that matches the actual effect of compliance and emission reduction plan,the independent compliance committee should be the subject of supervision,and the national capacity of emission reduction should be combined to define the boundary of various circumstances and implementation measures for non-compliance. Assist clauses including financial and technical support are formulated. Meanwhile,reprimand and suspension of relevant rights are also formulated for cases of malicious evasion of compliance. However,non-compliance procedures will continue to mainly encourage compliance,with a view to ensuring the parties' compliance with emission reduction commitments and compliance with compliance targets.
