Abstract

To achieve the European Uniońs climate goals, the Norwegian transport sector has committed to decrease the Greenhouse gas (GHG) emissions by 2030. For infrastructure projects, the GHG emissions from construction must be reduced by 40 %, while the emissions from maintenance must be cut by 50%. This paper investigates how realistic the GHG emission reduction goals are, if available low carbon materials and technologies are fully adopted. To examine this, we have chosen a typical Norwegian road tunnel from which two carbon emission scenarios are presented. While tunnels represent a specific subset of road infrastructure, this study showcases that implementing sustainable practices in drill and blast tunnel construction can align with the European Union’s ambitious 2030 targets. Besides this, the findings can assist stakeholders to get advice on the environmental impacts of tunnel designs.

公路隧道的温室气体减排潜力--现有材料和技术能否实现欧盟目标？

为实现欧盟的气候目标，挪威交通部门承诺到 2030 年减少温室气体排放。在基础设施项目中，施工产生的温室气体排放量必须减少 40%，而维护产生的排放量必须减少 50%。本文研究了如果完全采用现有的低碳材料和技术，温室气体减排目标的现实性有多大。为此，我们选择了一条典型的挪威公路隧道，并从中提出了两种碳排放方案。虽然隧道是公路基础设施的一个特殊子集，但这项研究表明，在钻爆隧道施工中采用可持续的做法，可以与欧盟雄心勃勃的 2030 年目标保持一致。此外，研究结果还有助于利益相关者获得有关隧道设计对环境影响的建议。

期刊介绍： Tunnelling and Underground Space Technology is an international journal which publishes authoritative articles encompassing the development of innovative uses of underground space and the results of high quality research into improved, more cost-effective techniques for the planning, geo-investigation, design, construction, operation and maintenance of underground and earth-sheltered structures. The journal provides an effective vehicle for the improved worldwide exchange of information on developments in underground technology - and the experience gained from its use - and is strongly committed to publishing papers on the interdisciplinary aspects of creating, planning, and regulating underground space.
