Study of the environmental impacts based on the “green tax”—applied to several types of building materials

This paper presents a method using building materialsʹ environmental profiles to assess their environmental impacts based on the life-cycle assessment (LCA) framework. In this method, the environmental impacts are categorized and the “green tax” is used to study the inter-seriousness across different categories. The green tax including the pollutant tax and resource tax is the shadow price of pollutants or resources, revealing the social willingness-to-pay (WTP) for them. The green tax of a specific pollutant could be modified if the local special preference is considered. The final assessment result produced by this method represents the social WTP for the environmental impacts of the building material.
