Life cycle assessment (LCA) aims to provide a near full accounting of impacts from the complete life of a product, to avoid burden shifting between different parts of the life cycle. However, this is exceptionally difficult with transport infrastructure because important parts of their impact lie outside the widely applied industrial‐product‐oriented LCA life stages: production, manufacturing, use, and end of life. To account for those missing impacts, we propose a new framework for assessing the life cycle impacts of transport infrastructure. This framework takes account of the differences between transport infrastructure and the industrial product system to which LCA is most attuned. First, rather than a linear process from material extraction to disposal, this LCA framework accommodates the multiple iterations of transport infrastructure through circular life stages. These reflect the long lifetimes, durability, persistence, and feedback loops of transport infrastructure. Second, this framework recognizes the impact at the start of the life cycle created by demolition of previous infrastructure or land clearing. Third, the tightly linked external impacts that transport infrastructure induces, including influences on travel behavior, local land use, land use, land use change and forestry, and network effects are captured. Fourth, this framework recharacterizes “end of life” as “partial end of life,” in reflection of the widespread reconstruction, major refurbishment of and persistence of indirect impacts from transport infrastructure.

重新考虑运输基础设施的环境LCA生命周期,以促进整体评估

生命周期评估(LCA)的目的是提供对产品整个生命周期的影响的几乎完整的计算,以避免负担在生命周期的不同部分之间转移。但是,这对于运输基础设施而言异常困难,因为其影响的重要部分不在广泛应用的面向工业产品的LCA生命阶段之外:生产,制造,使用和寿命终止。为了解决这些遗漏的影响,我们提出了一个评估运输基础设施生命周期影响的新框架。该框架考虑了LCA最适合的运输基础设施与工业产品系统之间的差异。首先,不是从材料提取到处理的线性过程,该LCA框架可适应循环生命周期中运输基础设施的多次迭代。这些反映了运输基础设施的长寿命,耐用性,持久性和反馈回路。其次,该框架认识到拆除旧基础设施或清理土地对生命周期开始时的影响。第三,交通基础设施引起的紧密联系的外部影响,包括对旅行行为,当地土地利用,土地利用,土地利用变化和林业以及网络效应的影响。第四,该框架将“报废”定性为“报废部分”,这反映了交通基础设施的广泛重建,重大整修和间接影响的持续存在。运输基础设施的持久性,持久性和反馈回路。其次,该框架认识到拆除旧基础设施或清理土地对生命周期开始时的影响。第三,交通基础设施引起的紧密联系的外部影响,包括对旅行行为,当地土地利用,土地利用,土地利用变化和林业以及网络效应的影响。第四,该框架将“报废”定性为“报废部分”,这反映了交通基础设施的广泛重建,重大整修和间接影响的持续存在。运输基础设施的持久性,持久性和反馈回路。其次,该框架认识到拆除旧基础设施或清理土地对生命周期开始时的影响。第三,交通基础设施引起的紧密联系的外部影响,包括对旅行行为,当地土地利用,土地利用,土地利用变化和林业以及网络效应的影响。第四,该框架将“报废”定性为“报废部分”,这反映了交通基础设施的广泛重建,重大整修和间接影响的持续存在。交通基础设施引起的紧密联系的外部影响,包括对旅行行为,当地土地利用,土地利用,土地利用变化和林业的影响,以及网络效应。第四,该框架将“报废”定性为“报废部分”,这反映了交通基础设施的广泛重建,重大整修和间接影响的持续存在。交通基础设施引起的紧密联系的外部影响,包括对旅行行为,当地土地利用,土地利用,土地利用变化和林业的影响,以及网络效应。第四,该框架将“报废”定性为“报废部分”,这反映了交通基础设施的广泛重建,重大整修和间接影响的持续存在。
