摘要

英国需要减少其运输部门的二氧化碳排放，以实现其净零排放目标。本文研究了20世纪60年代建成的两座高速公路桥的二氧化碳循环。排放估计是通过二氧化碳排放强度和与类似资产的已公布数据进行比较来验证的，而用户排放是通过对使用这些资产的车辆数量的估计来估计的。从这些例子中可以得出关于过去和未来二氧化碳排放的结论。这项工作证实，减少用户产生的排放，而不是资本或运营和维护排放，是实现净零目标的关键。

Examples of carbon dioxide emissions data in the circular economy: highway transport

The UK needs to reduce the carbon dioxide emissions of its transport sector to meet its net zero target. This paper considers the carbon dioxide cycle for two motorway bridges built in in the 1960s. The emissions estimates are validated using both carbon dioxide emission intensity and by comparison with published data of similar assets, while user emissions are estimated from estimates of the number of vehicles using the assets. Conclusions on past and future carbon dioxide emissions are drawn from these examples. The work confirms that driving down user-generated emissions rather than capital or operational and maintenance emissions is the key to achieving net zero targets.

期刊介绍： Civil Engineering, listed by the Web of Science, is the ICE''s flagship journal. Practical and diverse in its scope, it publishes overview papers for the non-specialist on any subject relevant to civil engineering today. Topics range from landmark projects to philosophical, ethical, environmental, management and safety issues. Peer review, copyediting, and colour publication by Civil Engineering are free. If accepted, published papers are easily found by Google search, as well as in specialist citation indexes. There is also the option of making your article open access, should you wish to. Published authors receive a free electronic copy of their article to share with their peers. Furthermore, as well exposure to ICE''s 91,000-strong membership, published papers are promoted via our social media channels, accessing the wider civil engineering community. It is free to submit a paper to this journal. Papers appear Ahead of Print (below) as soon as they are ready to be published. Ahead of print articles are fully citable. using the DOI system
