Greenhouse gases refer to gases including carbon dioxide, methane, nitrous oxide, and fluorocarbons that have an impact on the global climate.  Corporate greenhouse gas accounting refers to the systematic quantification and reporting of a company's greenhouse gas emissions, which helps the company scientifically and effectively measure the actual effect of greenhouse gas emissions reduction, establish emission reduction targets, and make the emission reduction effect measurable, reportable, and verifiable (MRV).

Corporate greenhouse gas accounting typically includes the following steps:

Determine emission sources: Identify the greenhouse gas emission sources of the company, including production processes, energy use, transportation, etc.

Determine emission factors: Determine the greenhouse gas emission factors for each emission source, which are the CO2 equivalents emitted per unit of each type of pollutant.

Calculate emissions: Based on the company's annual production, energy consumption, transportation, and other data, calculate the greenhouse gas emissions produced by the company each year.

Analyze data: Analyze the greenhouse gas emission data, identify emission peaks, high-emitting sources, etc., and provide the basis for reducing greenhouse gas emissions for the company.
