【Chemical Machinery and Equipment Network Policies and Regulations】High-precision monitoring of greenhouse gases is a necessary tool to achieve the goal of carbon peak and carbon neutrality, and to ensure the accuracy and comparability of monitoring data, it depends on a perfect standard measurement system
.
The "Carbon Monitoring and Assessment Pilot Plan" issued by the Ministry of Ecology and Environment clearly requires "the construction of an accurate and unified environmental greenhouse gas monitoring and traceability system", and the "Opinions on Complete, Accurate and Comprehensive Implementation of the New Development Concept to Do a Good Job in Carbon Peaking and Carbon Neutrality" also points out that it is necessary to "improve the standard measurement system and establish and improve the standard measurement system for carbon peaking and carbon neutrality"

.
In this context, China Environmental Monitoring Station and the Chinese Academy of Metrology have jointly compiled and completed three technical regulations: "Technical Regulations on Traceability of High-precision Monitoring Measurement of Ambient Air Carbon Dioxide (Trial)", "Technical Regulations on Traceability of High-precision Monitoring of Ambient Air Methane (Trial)", and "Technical Regulations on High-precision Spectral Statutory Values of Ambient Air Carbon Dioxide and Methane Standard Gases (Trial)", which were officially released
recently.
recently.
The Technical Provisions on Traceability of High-precision Monitoring Measurement of Ambient Air Carbon Dioxide (Trial) and the Technical Provisions on Traceability of High-precision Monitoring of Ambient Air Methane (Trial) respectively apply to the traceability of the measurement of high-precision monitoring of ambient air carbon dioxide and methane, and stipulate the use of ambient air carbon dioxide and methane measurement standards, and the complete set of basic measuring instruments included in the benchmarks, with the help of reference standard gas, secondary standard gas, tertiary standard gas, and four-level standard gas, Methods and procedures for transmitting the measurement of carbon dioxide and methane concentrations from the measurement reference to the working measuring instrument, and the extended uncertainty of the transfer of the measurement value
.
When calibrating, it can also be used as a basis
for traceability of the measurement value.

The Technical Provisions on High-precision Spectral Statutory Values of Ambient Air Carbon Dioxide and Methane Standard Gases (Trial) puts forward the technical points of high-precision valuation of ambient air carbon dioxide and methane standard gases, including the composition of the fixed value system, the performance requirements of each link of the fixed value system, the fixing method, quality control and quality assurance
.
It can provide standard gases that meet the requirements for data calibration and quality control of related high-precision monitoring instruments, and standardize the high-precision step-by-step value determination of
greenhouse gas standard gas in urban ambient air.

The above three technical requirements further strengthen the construction of the traceability system of greenhouse gas monitoring and provide a quality basis
for high-precision greenhouse gas monitoring.
The follow-up environmental monitoring station will revise according to the progress of greenhouse gas valuation work, and continue to issue a series of technical regulations related to the traceability of greenhouse gas monitoring values, so as to provide technical support
for China to complete the dual carbon goal and achieve green development.
