Carbon emission reduction based quantification method for environmental benefits of urban rail transit

Abstract

The present invention relates to a carbon emission reduction based quantification method for environmental benefits of urban rail transit. The method comprises the following steps of: 1) establishing a basic database; 2) based on a passenger flow transfer mechanism, and according to survey data of residents around the rail transit and data of a road transport bureau, acquiring a carbon emission reduction amount of the rail transit reduced in rail transit operation; 3) based on a shadow price theory, and according to data of a statistical bureau, acquiring a carbon emission shadow price of the traffic industry; 4) based on a carbon transaction price model, and according to the carbon emission shadow price and data of a carbon transaction market, acquiring an actual carbon transaction price of the traffic industry; and according to the carbon emission reduction amount and the actual carbon transaction price, acquiring an environmental benefit monetary value generated by the rail transit operation. Compared with the prior art, the quantification method has the characteristics that factors such as the carbon emission reduction, the passenger flow volume, the carbon price and the like are taken into consideration, the environmental benefits generated by line operation of the urban rail transit are quantified, and a quantified entity can serve as a reference amount of carbon tax collection of governments.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a method for quantifying the environmental benefits of urban rail transit based on carbon emission reduction. Background technique [0002] Urban rail transit has gradually become the first choice for cities to solve traffic problems and ensure sustainable urban development due to its advantages of large capacity, fast speed, safety and comfort, punctuality, and environmental friendliness. Under the guidance of national policies, my country's urban rail transit has entered a stage of leapfrog development. As of December 2014, more than 80 urban rail transit lines have been built and officially operated in 21 cities in mainland China, with a total mileage of more than 2000km. However, the huge external benefits of rail transit cannot be internalized due to the lack of reasonable quantification methods, and cannot be transformed into internal benefits by relying on norm...

Problems solved by technology

[0005] (1) Although preventive expenditure method, protective expenditure method, willingness to pay and other methods are currently commonly used models in environmental accounting, they are too subjective and easy to deviate from the real value

[0006] (2) Existing models cannot support the transformation of huge and difficult-to-measure environmental benefits into internal benefits through market mechanisms
