Chapter 8, Article 42 of the Measures for the Administration of Carbon Emissions Trading explains greenhouse gases and carbon emissions: carbon emissions refer to the greenhouse gas emissions generated by the combustion activities of fossil energy such as coal, oil and natural gas, as well as industrial production processes, land use change and forestry activities, including the greenhouse gas emissions generated by the use of outsourced electricity and heat.
Greenhouse gas refers to the gas that can absorb and reflect long-wave infrared radiation in the atmospheric environment. The six greenhouse gases specified in Kyoto Protocol are nitrous oxide N2O, methane CH4, carbon dioxide CO2, sulfur hexafluoride SF6, perfluorocarbon PFCs and hydrofluorocarbons HFCs, among which the first three gases are difficult to control effectively, so they are the key monitoring items of greenhouse effect.

What is carbon emission?
Carbon emission is the general name or abbreviation of greenhouse gas emission. The main gas in greenhouse gas Z is carbon dioxide, so it is represented by the word carbon. Most scientists and governments admit that greenhouse gases have brought and will continue to bring disasters to the earth and mankind, so the terms "(control) carbon emissions" and "carbon neutrality" have become the cultural basis for most people to understand, accept and take action.
The main source of carbon emissions
Any human activity may cause carbon emissions. Various fuels, gas, paraffin, coal and natural gas will produce a large amount of carbon dioxide in the process of use, as well as in urban operation, people's daily life and transportation (planes, trains, cars, etc.). ).
The main source of carbon emissions is fossil fuels. Fossil fuel, also known as fossil fuel, is a mixture of hydrocarbons or hydrocarbon derivatives, including natural resources such as coal, oil, natural gas, oil shale, oil sands and seabed combustible ice. During the combustion of fossil fuels, carbon is converted into carbon dioxide and enters the atmosphere, which increases the emission of greenhouse gases. Z is widely used in fossil fuels such as coal, oil and natural gas, and is also the main source of carbon dioxide. Among them, the carbon content of coal is very rich, and the combustion of coal will emit a lot of carbon dioxide.
How to monitor carbon emissions and greenhouse gases?
For the monitoring of carbon emission greenhouse gases, the atmospheric carbon emission monitoring system can be installed at the exhaust pipes of various combustion boilers, industrial kilns and other devices in addition to using the accounting system owned by each customer for calculation and detection, and can monitor the concentrations of greenhouse gases such as carbon dioxide, methane and nitrous oxide on line in real time.
Taking ERUN-GHG3000 greenhouse gas emission on-line monitoring and analysis equipment with micro-flow infrared sensing technology as an example, the concentrations of N2O, N2O, CH4, CO2 and CO2 and the contents of O2, O2 and CO in flue gas can be monitored on-line at the same time. Both double-beam infrared gas sensor and micro-flow infrared gas sensor can accurately measure high-concentration and low-concentration greenhouse gases.
