The 2022 National Ecological Environment Protection Working Conference pointed out that the second performance cycle of the national carbon emission trading market should be managed well, and the scope of industry coverage and trading subjects should be expanded. We will improve the long-term mechanism for carbon emission data quality management, continue to organize and carry out carbon emission report quality supervision and assistance, and severely crack down on data fraud and illegal acts.
Previously, in October 2021, the Ministry of Ecology and Environment issued the Notice on Doing a Good Job in the Data Quality Supervision and Management of the National Carbon Emission Trading Market, which clearly proposed that local ecological environment departments should effectively improve their understanding of the importance of doing a good job in the data quality supervision and management of the national carbon market and carry out data quality self inspection.
Why is carbon data quality so important? What links are relevant to the authenticity and accuracy of carbon data?
Why is data quality the lifeblood of the carbon market?
The reporter learned that there had been cases of falsification of carbon emission data by individual enterprises and units that disrupted the order of the carbon market before. In order to investigate and deal with the falsification of greenhouse gas emission data according to law and regulations, the Ministry of Ecology and Environment launched a special action to supervise and help the quality of carbon emission reports for the power industry in 2021.
"Carbon verification involves many links such as energy types, industrial processes and waste disposal, so some enterprises may not be able to master all the details in a short period of time. Through the supervision and assistance activities, it can help enterprises to figure out their carbon emissions and carbon assets, improve the data quality of the carbon market, and more conducive to the play of the functions of the carbon market." Sun Yongping, executive deputy director of Hubei Collaborative Innovation Center for carbon emission trading, said.
"Data quality is the lifeblood of the carbon market and the cornerstone of the stable and effective operation and healthy and sustainable development of the national carbon market." An industry insider analyzed and said, "At the same time, the quality of corporate carbon emission data is also the bottom line and lifeline to maintain market credit confidence and the credibility of national policies."
The authenticity of carbon emission data is closely related to the healthy development of the carbon market. In 2021, the Ministry of Ecology and Environment organized the first phase of special supervision and assistance on the quality of national carbon emission reports, and carried out the inspection and supervision on the quality of carbon emission reports for 264 emission control power enterprises in 10 cities in 5 provinces. All working groups moved into relevant cities on November 25, 2021, and the on-site work lasted about 10 to 14 days.
How to strengthen and ensure data quality?
Since 2013, China's carbon trading has made many explorations in pilot areas. Among them, one of the most important tasks is to explore the way for the construction of the national carbon market MRV system.
MRV system is mainly composed of measurement, reporting and verification. According to the principle of "measurability, reportability and verifiability" and the technical system, it can ensure the authenticity, accuracy and integrity of the quota permit and actual emissions. It is not only a good practice of common practices, but also an institutional guarantee for the success of China's carbon market construction.
"At this stage, the construction system of the national carbon market will also strengthen the protection of the data quality of the carbon market from the three aspects of measurement, reporting and verification to ensure the smooth and effective operation and healthy and sustainable development of the national carbon market." Liu Qingzhi, deputy general manager of the Central United Certification Center, said in an interview with our reporter earlier.
Among them, measurement means that emission units monitor and account for their own carbon emissions in a unified way. The measurement technology and results directly affect the accuracy and reliability of carbon emissions. Therefore, it is necessary to find out the overall technical process and equipment level, resource and energy utilization level, energy consumption measurement level and laboratory measurement and analysis level of the industry to determine the measurement rules and methods.
Reporting refers to the process in which the emission unit submits the measured, measured or accounted greenhouse gas emissions to the competent department. Verification refers to the activity of inviting a third party institution to review the greenhouse gas emission report of the emission unit and judge whether its accounting and report meet the requirements.
"From the experience at home and abroad, carbon verification is not only the common practice of data quality assurance, but also an effective means to improve data quality." A person in the field of carbon trading research pointed out.
In order to do a good job in carbon data verification, since China launched the "6+1" pilot carbon trading in 2013, the carbon trading authorities in the pilot areas have organized the verification of the historical year and performance year data of emission units. The carbon emission verification has provided quality assurance for the pilot carbon trading data and made important contributions to the smooth and smooth operation of the pilot carbon trading.
In the future, focusing on the national carbon market, the provincial competent department of ecological environment can not only entrust the technical support unit within the system to carry out the verification, but also entrust social technical service institutions to carry out the verification by means of government purchase of services.
