Dataset for the Life Cycle Assessment of the High Speed Rail network in Spain

A life cycle assessment (LCA) of the entire high speed rail (HSR) network in Spain 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. LCI data associated with the operation phase of the infrastructure was built on available fragmentary data on passenger movements for the year 2016, processed with a python algorithm to estimate the transport service provided by the infrastructure. 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. This dataset presents a detailed description of the Spanish HSR network, including the length of each item (bridges, tunnels, earthworks, railway tracks), and a robust estimation of passenger transport over the infrastructure for year 2016.

一项针对西班牙高速铁路（HSR）网络全生命周期的综合评估（LCA）已圆满完成。通过运用Google Earth工具，收集了与基础设施建设与维护阶段相关的生命周期清单（LCI）数据，并辅以其他生命周期研究获得的数据进行补充。针对基础设施运营阶段的生命周期清单数据，基于2016年乘客流动的零散数据构建，并通过Python算法进行处理，以估算基础设施提供的运输服务。交通方式的环保影响数据来源于Ecoinvent v3.7数据库，并使用openLCA软件进行处理。数据集中收集的生命周期影响评估（LCIA）结果包括全球变暖（GWP100a）、累积能源需求以及PM10、SO2、NOX和NMVOC的总排放量。本数据集详细描述了西班牙高速铁路网络，包括每项工程（桥梁、隧道、土方工程、铁路轨道）的长度，以及对2016年基础设施上旅客运输的稳健估算。
