Cable cars have slowly become a popular means of transport beyond their classical use at ski resorts. In Latin America their use has thrived to access archaeological sites in the Andes, but also in urban environments for mass transit. Despite some apparent benefits of these systems, the current literature is scarce in terms of quantifying the environmental profile of cable cars. Hence, their environmental performance as compared to other means of transport remains essentially unexplored. Therefore, the main objective of this study was to provide a comparative environmental analysis, using Life Cycle Assessment (LCA) methodology, of the two existing transport methods to visit the Kuelap Archaeological Complex, in northern Peru: a recently built cableway system and the alternative unpaved winding road. An attributional LCA perspective was performed for several impact categories, including global warming and particulate matter formation. In addition, a scenario analysis and an uncertainty analysis, using Monte Carlo simulation, were conducted to account for deterministic and stochastic results interpretation. Results demonstrated that succulent environmental benefits are attained when cable cars substitute road transport in complex Andean orographic conditions. However, the rebound effects of reducing traveling times significantly, as well as social and biodiversity aspects, should be analyzed in further depth to complement the environmental analysis.
缆车已逐渐成为一种流行的交通工具，除了在滑雪胜地的经典用途外。在拉丁美洲，它们被用于进入安第斯山脉的考古遗址，但也用于城市环境中的大众交通。尽管这些系统有一些明显的好处，但目前关于量化缆车环境状况的文献却很少。因此，与其他交通工具相比，它们的环境性能基本上尚未得到探索。因此，本研究的主要目的是使用生命周期评估（LCA）方法，对秘鲁北部的库埃拉普考古综合体的两种现有交通方式进行比较环境分析：最近建成的缆车系统和替代的未铺砌的蜿蜒道路。对包括全球变暖和气态颗粒物形成在内的多个影响类别进行了归因 LCA 分析。此外，还进行了情景分析和不确定性分析，使用蒙特卡罗模拟来考虑确定性和随机结果的解释。结果表明，在复杂的安第斯地形条件下，缆车替代公路运输可以带来明显的环境效益。然而，应进一步深入分析大幅减少旅行时间的反弹效应，以及社会和生物多样性方面，以补充环境分析。
