Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy saving and emission reduction, and particularly relates to a carbon emission reduction amount calculation method. BACKGROUND

[0002] Business cargo transportation (road, water, rail, air) is an important part of the transportation industry, and its carbon emission accounts for a large proportion of the entire transportation industry. Carbon emission reduction calculation is to calculate the carbon emission reduction effect of different policy measures. Existing policy measures mainly include promoting transportation structure adjustment, accelerating new energy transportation vehicles, railway electrification and civil aviation bio-jet fuel application. The carbon emission reduction effect of different policy measures needs to convert the policy measures into quantitative parameters, scientifically quantitatively predict the carbon emission before and after the implementation of the policy measures, and finally calculate the carbon emission reduction amount under different policy measures.

[0003] At present, the carbon emission of the transportation industry is mainly calculated by the "bottom-up" or "top-down" method, and the carbon peak time and carbon emission peak under different policy measures are calculated. Although this method can predict the carbon emission trend of the transportation industry, it cannot determine the emission reduction effect after the implementation of a certain policy measure.

[0004] In the prior art, the patent document with the publication number CN106600027A discloses a carbon emission calculation system and method for urban transportation. The calculation boundary is intercity passenger transport, urban passenger transport and urban freight transport, which is equivalent to the calculation boundary of the passenger transport part of highway transportation and urban passenger transport. The emission reduction amount of business highway, waterway, railway and civil aviation freight transport is not calculated. Moreover, the policy parameterization is a hypothesis that applies the macro policy measures published by the government and industry to different scenarios. The policy measures are not directly converted into parameter values to calculate the emission reduction result.

[0005] The patent document with the publication number CN114417614A discloses a carbon emission reduction amount calculation method under the spatial control measures of central urban motor vehicles. The calculation boundary is public transportation and cars in central urban areas, and the emission reduction amount of business highway, waterway, railway and civil aviation freight transport is not calculated. The purpose of the invention is to verify the influence on the emission reduction effect after the implementation of a certain traffic control measure.

[0006] There is no related content in the prior art that can directly evaluate the emission reduction effect of each policy measure, and it is impossible to predict the emission reduction effect after the implementation of a certain policy measure. SUMMARY
