Fine calculation method for carbon emission of urban rail transit

Abstract

As an important part of modern integrated transportation system, urban rail transit generates carbon emissions mainly by consuming electric energy. Aiming at the problems such as single index and weak accuracy of the current carbon emissions accounting method for urban rail transit, this study builds a refined carbon emissions calculation model based on existing industry standards and norms, puts forward refined carbon emissions calculation factors under different conditions, and designs efficient algorithms to solve them. The research hopes to provide a basis for differentiated policy formulation for urban rail transit operators, so as to facilitate urban rail transit operators to obtain more say in carbon trading, complete carbon quotas more scientifically and rationally, and better help urban rail transit enterprises to complete the strategic goal of "carbon neutrality"and "carbon peak".
