Enterprises have the right to emit greenhouse gases (carbon dioxide, etc.) into the atmosphere according to law, which can be called "carbon emission right". Approved by the competent government department, the enterprise will obtain the total amount of "legal" greenhouse gas emissions within a certain period of time, which is the quota. When the actual emission of the enterprise exceeds the allocated carbon quota, the part needs to be purchased; When the actual emissions of enterprises are less than the carbon quota, the balance can be sold in the carbon trading market. The issuance and performance of carbon emission quotas of emission control enterprises are supervised and implemented by relevant competent authorities of the state, which is an administrative and legally binding performance mechanism. With its financial strength and professional carbon asset management ability, carbon removal technology (Wuxi) Co., Ltd. can provide various performance schemes and carbon financial arbitrage schemes for emission control enterprises, help emission control enterprises improve the risk management ability of carbon emission trading, reduce the performance cost, and help enterprises focus on their main business and avoid unnecessary risks and costs.

In June 2012, the national development and Reform Commission issued the CCER programmatic guidance document Interim Measures for the administration of voluntary greenhouse gas emission reduction transactions (FGC [2012] No. 1668). It defines the trading products, trading places, application procedures for new methodologies, and the identification procedures for the qualification of examination and certification institutions. CCER can involve 16 project development fields.

Green power trading is a trading variety set up within the framework of medium and long-term power market mechanism with wind power, photovoltaic and other green power products as the subject matter, which can fully reflect the power value and environmental value of green power, and provide corresponding green power consumption certification.

At present, the EU is at the forefront of the world in promoting emissions trading. The EU has formulated an EU gas emission trading scheme applicable to the EU region, which allows emission reduction subsidies to enter the market by identifying the greenhouse gas emissions of 10000 units in specific fields, so as to achieve the goal of reducing greenhouse gas emissions. Since the beginning of trading in the EU carbon emission market, the trading volume and transaction amount have increased steadily. Chinese factories and international carbon traders are also making huge profits from greenhouse gas emissions trading. Chemical plants can obtain carbon emission credits by reducing the emission of polluting hydrofluorocarbon gases into the atmosphere. This kind of credit can be sold in US dollars to US dollars on the international carbon emission trading market.
