Carbon Dioxide Mitigation Benefit of High-Speed Railway in Terms of Carbon Tax

الملخص EN

This paper calculates the carbon dioxide mitigation benefit of high-speed railway based on the carbon dioxide tax policy.

We define the carbon dioxide emission system boundary for high-speed railway in its whole life cycle and estimate the life cycle carbon dioxide inventories during its construction, application, and recovery stages.

And then we establish a theoretical model to calculate the life cycle carbon dioxide mitigation quantity for high-speed railway when compared with road transport and then calculate its carbon dioxide mitigation benefit.

The numerical example shows that the carbon dioxide mitigation benefit of high-speed railway is better than that of road transport from the whole life cycle perspective.
