It is necessary to strengthen the legal guarantee on actions addressing climate change in order to successfully achieve the “Carbon Peaking and Carbon Neutrality Goals” proposed by China. China has promulgated a series of laws and policies related to actions addressing climate change，but there is no specialized and comprehensive law on actions addressing climate change and the local legislation has many limits in terms of effectiveness，regulatory content and scope of application. The existing ecological environment protection legislation is insufficient to deal with climate change，and it is necessary to strengthen the coordination between ecological environment protection and climate change or greenhouse gas emission reduction. The law on actions addressing climate change should be introduced as soon as possible，the systematic construction should be improved，and the relevant legislation on ecological environment protection should be revised and improved，in order to better promote the comprehensive coordination between ecological environment protection and the work related to actions addressing climate change.
