Description

Technical Field

[0001] The present invention relates to the field of highway construction engineering, and in particular to a method for calculating carbon emissions during a structured highway construction phase based on a budget quota. Background Art

[0002] Global warming has become a hot topic of great concern to the international community today. The main cause of global warming is greenhouse gas emissions caused by human activities, and carbon dioxide is the most important anthropogenic greenhouse gas in the atmosphere, accounting for about 66% of the warming effect. The transportation industry is one of the main sources of global carbon dioxide emissions, accounting for about 27% of the total global carbon dioxide emissions related to energy activities, and is also one of the fastest growing industries. In the transportation industry, highway transportation projects are the absolute main body of carbon dioxide emissions and the focus of emission reduction. From the perspective of the development of the transportation industry, with the continuous increase in the total mileage of traffic, the high carbon emissions, high energy consumption and environmental damage brought about by highway construction are serious. Controlling and reducing carbon emissions from highway construction is one of the key and effective ways to reduce transportation carbon emissions and alleviate my country's carbon emission pressure. At present, there is no unified method for quantitative measurement of carbon emissions in my country's highway engineering field. How to quantitatively measure and analyze carbon emissions during the construction period of highway projects, and grasp the characteristic process and emission of carbon emissions during the construction of highway projects. There is still a lack of appropriate methods, which to a certain extent hinders the development and progress of energy conservation and carbon reduction in the highway industry. Therefore, studying the carbon emission calculation method during the highway project construction period is particularly important and urgent in the current important era of energy conservation and carbon reduction in China's national economy.
