At present, the “low-carbon economy” has become the focus of global attention, and the large amount of carbon dioxide emissions will have a huge negative impact on the environment, the economy and other aspects. Among the main industries of China's carbon dioxide emissions, the industrial sector accounts for more than 65% of the total emissions, which is the main source of carbon dioxide emissions. To address this issue, carbon dioxide emission reduction in industrial parks has become imminent. In the carbon emissions of industrial parks, the proportion of unorganized emissions is 30%–50%, and carbon dioxide emission reduction in industrial parks relies on the accurate estimation of carbon dioxide emissions. By collecting and analyzing carbon dioxide emission data, industrial parks can take necessary measures to reduce energy waste and emissions. Therefore, analyzing the concentration of unorganized carbon dioxide emissions in industrial parks can provide a clear understanding of the carbon dioxide concentration in industrial parks, which is of theoretical value and practical significance for carbon dioxide emission reduction and energy transition.
