Legal analysis: Carbon emission trading refers to an important mechanism to use market economy to promote environmental protection, which allows enterprises to use these reduced carbon emissions to use or trade energy within enterprises and at home and abroad under the premise of not exceeding the total emissions stipulated in carbon emission trading. Carbon emissions trading is a tradable quota system, based on the quotas calculated by the emission reduction and limitation commitments listed in Annex B of the Protocol. For example, global carbon emissions are limited to 100 units, and country A gets 15 units, country B gets 10 units, and other countries get the remaining 75 units. If country A only emits 65,438+00 units and country B emits 65,438+02 units, then country B can buy 2 units of carbon emissions from country A. At present, the EU is at the forefront of the world in promoting carbon emissions trading and has formulated a gas emissions trading scheme suitable for the EU region. By identifying the greenhouse gas emissions of specific fields 1 10,000 units, emission reduction subsidies are allowed to enter the market, thus achieving the goal of reducing greenhouse gas emissions.

Legal basis: Article 17 of the Kyoto Protocol stipulates that the Conference of the Parties to the Convention shall determine the relevant principles, methods, rules and guidelines for emissions trading, especially their verification, reporting and responsibilities. Parties listed in Annex B may participate in emissions trading for the purpose of fulfilling their commitments under Article 3.

Any such trade shall supplement the domestic actions taken to realize the quantified emission limitation and reduction commitments stipulated in this Article.
