The Ministry of Ecology and Environment held a regular press conference online on May 26. China metallurgical newspaper reporter learned from the meeting, in September 2021, started to carry out the overall carbon monitoring and evaluation of pilot work goes well, thermal power, steel, oil and natural gas mining, coal mining and waste management five pilot industry set 119 monitoring points, most of the points have access to 3-5 months monitoring data, the effect of carbon monitoring 'preliminary.
The Ministry of Ecology and Environment introduced that it is focusing on "three comparisons" and "three differences" analysis of pilot data. "Three comparison", that is, monitoring data and accounting data comparison, manual monitoring and online monitoring comparison, imported equipment and domestic equipment comparison; "Three differences", that is, the data analysis of different monitoring principles, different types of coal burning and different monitoring points should be conducted to timely sum up experience, solve problems and evaluate results.
At present, the pilot work has achieved certain results. The role of carbon monitoring is mainly reflected in the following aspects: first, it can directly serve carbon emission accounting. In the pilot monitoring of coal mining and oil and gas mining, comprehensive monitoring of "satellite + UAV + navigation" can improve the comprehensiveness and accuracy of CH4 unorganized emission accounting in the production process. Second, the accounting method can be coordinated verification. According to the preliminary data obtained, the online monitoring effect of enterprises with relatively concentrated GREENHOUSE gas emissions is better. CO2 emission monitoring data of thermal power industry is basically consistent and comparable with accounting data, which is expected to play a further role in assisting enterprises' emissions accounting and supporting emission reduction regulation. Third, it can help urban peak action. Relying on the existing environmental air monitoring network, expanding and constructing the urban carbon monitoring network integrating heaven and earth, and exploring the "double carbon" inversion evaluation based on measurement means can provide support for promoting the key cities to achieve the "double reach" of air quality standards and CO2 peak.
The Ministry of Ecology and Environment said that the next step will continue to deepen the industry pilot, and strive to promote more thermal power enterprises to carry out CO2 online monitoring by the end of this year; We will speed up the building of a network, make good use of the atmospheric environment monitoring satellite launched on April 16 this year, and strengthen the support of REMOTE sensing data on CO2 and air pollutants. We should strengthen our weak links in capacity, encourage the country to accelerate the formation of carbon monitoring capacity and professional personnel, and provide forward-looking business reserves and technical support.
Ministry of Ecology and Environment: the overall improvement of ecological environment quality is still at a low level
On May 26, the Ministry of Ecology and Environment issued a communique on China's ecological and Environmental conditions 2021 and a communique on China's Marine Ecological and Environmental conditions 2021 at a regular press conference.
According to the Environmental Bulletin, the main indicators of ecological and environmental quality were successfully completed in 2021, with the national Ecological quality Index (EQI) at 59.77, ranking second class and basically stable compared with 2020. The average annual concentrations of PM2.5, PM10, O3, SO2, NO2 and CO all fell for the first time.
In terms of infrastructure and energy, by the end of 2020, a total of 372,962 sets of waste gas treatment facilities in gas-related industrial enterprises had been surveyed nationwide, with a sulfur dioxide removal rate of 95.5% and nitrogen oxide removal rate of 74.2%. A total of 68,150 wastewater treatment facilities in water-related industrial enterprises were surveyed nationwide, with a removal rate of 97.3 percent of chemical oxygen demand and 98.3 percent of ammonia nitrogen. In 2021, coal consumption will increase by 4.6 percent and electricity consumption by 10.3 percent.
"Monitoring, however, also found that the present ecological environment quality improving overall is still in the middle and lower level of ascension, the ecological environment of the good foundation is not solid, ecological environmental quality of a turning point from the quantitative to qualitative changes has not yet appeared, there are still some areas, some time, some index variation may be a significant fluctuations." Jiang Huohua, deputy director of the department of ecological environment monitoring, said that the future will accelerate the establishment and improvement of modern ecological environment monitoring system, actively promote the application of high and new technology in the field of ecological environment monitoring, while compaction pollutant discharge units and monitoring institutions responsible for the authenticity and accuracy of monitoring data responsibility.
In addition, according to the Marine Environment Bulletin, China's Marine ecological environment will be stable and improving in 2021. The overall quality of Marine environment continues to improve, typical Marine ecosystems are in a healthy or sub-healthy state, the water quality of rivers entering the sea in China is generally slightly polluted, and the environmental quality of major Marine areas is generally good.
