Summary:

In recent years, the greenhouse effect has become a major challenge for sustainable development, with carbon dioxide emissions playing a significant role. In 2022, China's carbon dioxide emissions reached 12,667,430 tons [1], the highest globally, with the transportation sector contributing about 8% of this, and road transportation accounting for 90% of the sector's emissions. To promote green development, the Chinese government emphasizes efficient resource use, energy conservation, and emissions reduction, aiming to build a strong transport system by 2035. Understanding carbon emissions in expressway construction is crucial for green development. Studies on highway carbon emissions focus on emissions from road construction and vehicle operation. For example, Chen and others used a "bottom-up" method to account for emissions during construction, while Tu and others created a vehicle carbon emission model during operation. With the expanding highway network, maintenance has become essential, but carbon emissions from highway maintenance are often overlooked. Lu and others divided emissions into material production, transportation, and construction stages, calculating the total emissions from these factors. Yang Yuanyuan and others divided emissions into six parts and proposed maintenance methods for different conditions. Zheng and others used a life-cycle approach to assess maintenance carbon emissions and compared methods to identify the least carbon-intensive option. Zhang added congestion and detour emissions to the transportation stage. This paper divides highway construction emissions into four categories: construction machinery, material transportation, construction materials, and recycled materials. It calculates emissions for each stage separately, making the method applicable to all types of expressways. The results of these calculations will contribute to assessing carbon reduction measures in expressway projects
