Abstract
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
