Environmental benefit calculation method for carbon emission reduction in high-speed railway operation period

Abstract

The invention relates to an environmental benefit calculation method for carbon emission reduction in a high-speed railway operation period, and belongs to the field of environmental protection. The environmental benefit calculation method comprises the steps of building a basic database according to relevant documents of the National Bureau of Statistics, the transportation statistics yearbook ofChina, the railway yearbook of China and the railway annual statistical bulletin; determining a weight value of a carbon emission reduction element in the high-speed railway operation period according to the database on the basis of mathematical analysis of the analytic hierarchy process; determining a high-speed railway carbon emission index according to the database based on the conversion between high-speed railway power consumption and the standard coal amount; and calculating the shadow price of carbon dioxide by adopting a trans-logarithm method according to the database based on a shadow price theory. The environmental benefit calculation method takes factors such as carbon emission reduction, carbon price and comparison of multiple transportation modes into consideration, and compares the high-speed railway operation period with highway, water transportation, air transportation and ordinary railways in carbon emission, thereby quantifying the carbon emission reduction benefitsof the high-speed railway, and being capable of providing a basis for the government and the railway to verify the carbon emission.

Description

technical field [0001] The invention relates to an environmental benefit calculation method for carbon emission reduction during the operation period of a high-speed railway, and belongs to the technical field of environmental protection. Background technique [0002] As the main artery of my country's national economy, the country's important infrastructure and popular means of transportation, railways play an important role in my country's social and economic development. Railway transportation conforms to my country's national conditions. Compared with other transportation methods such as road, water transportation and shipping, comprehensive comparison of railway has the advantages of large transportation volume, fast speed, low transportation cost, safety and reliability, etc. Generally speaking, it is suitable for medium and long-distance bulk transportation. Cargo and passenger transportation. With the development of science and technology, China's railways have enter...
