Detailed description of the layout of the Basque Y HSR project in Spain

A life cycle assessment (LCA) of the Basque Y high speed rail (HSR) line was completed. Life cycle inventory (LCI) data related to the construction and maintenance phases of the infrastructure was collected using Google Earth tool, and complemented with data obtained from other LCA studies. This dataset presents a detailed description of the Basque Y HSR line, including the length of each item (bridges, tunnels, earthworks, railway tracks).Environmental impacts for transport modes were obtained from Ecoinvent v3.7 database and processed with openLCA software. Life cycle impact assessment (LCIA) results gathered in the dataset include Global Warming (GWP100a), Cumulative Energy Demand and total emissions for PM10, SO2, NOX and NMVOC.本研究针对巴斯克Y高速铁路（HSR）线路完成了生命周期评估（LCA）。研究期间，通过谷歌地球（Google Earth）工具采集了该基础设施建设与运维阶段的生命周期清单（LCI）数据，并补充了其他生命周期评估研究获取的相关数据。本数据集详细描述了巴斯克Y高铁线路的各项构成，包含桥梁、隧道、土石方工程、铁路轨道的具体长度。交通模式的环境影响数据取自Ecoinvent v3.7数据库，并通过openLCA软件完成处理。本数据集收录的生命周期影响评估（LCIA）结果涵盖全球变暖潜势（GWP100a）、累计能源需求，以及PM10、二氧化硫（SO2）、氮氧化物（NOₓ）与非甲烷挥发性有机化合物（NMVOC）的总排放量。
