North America Estimated Annual Rail CO2 Emissions 2035

This map shows the estimated annual freight railroad CO2 emissions for the year 2035 along the Mexico City to Montreal transportation corridor. Carbon dioxide emissions are measured as kilotonnes per kilometer. The transportation corridor is one of several that cross North America and the main freight railroads are based on the North American Environmental Atlas’ base layer. The railroads included are either rail links between major centers of population or major resource railways. Note there is no classification of rail lines. Data Source The data were collected by the Texas Transportation Institute (TTI) from various sources as part of the Greening North American Transportation Corridors: Challenges and Opportunities paper published by the CEC (www.cec.org/freight). The major source for data on rail freight movement was the FHWA’s Freight Analysis Framework (FAF and FAF2). In Canada, the information included for the estimation came from the Canadian National Railway Company. In Mexico, the information that was used was from the Instituto Mexicano de Transporte (IMT). Other data sources encompass the Bureau of Transportation Statistics’ (BTS) National Transportation Atlas Database (NTAD) and North American Transborder Freight Data (NATFD), and other rail and freight databases. Files Download本地图展示了2035年墨西哥城至蒙特利尔运输走廊沿线的货运铁路二氧化碳（Carbon Dioxide, CO2）估算年排放量。二氧化碳排放量以千吨/千米为计量单位。该运输走廊为横贯北美的多条运输走廊之一，其主要货运铁路线依托北美环境图集（North American Environmental Atlas）的基础图层制作。纳入本数据集的铁路线路，要么是连接主要人口中心的铁路连接线，要么是重要的资源运输干线铁路。需注意，本数据集未对铁路线路进行分类。 数据来源 本数据集的数据由德克萨斯交通研究所（Texas Transportation Institute, TTI）从多渠道收集，源自CEC发布的《绿化北美运输走廊：挑战与机遇》论文，相关论文可访问网址：www.cec.org/freight。铁路货运活动数据的主要来源为美国联邦公路管理局（Federal Highway Administration, FHWA）的货运分析框架（Freight Analysis Framework, FAF及FAF2）。在加拿大，排放量估算所用的信息来自加拿大国家铁路公司（Canadian National Railway Company）；在墨西哥，所用信息来自墨西哥交通运输研究所（Instituto Mexicano de Transporte, IMT）。其余数据来源包括美国运输统计局（Bureau of Transportation Statistics, BTS）的国家运输图集数据库（National Transportation Atlas Database, NTAD）、北美跨境货运数据（North American Transborder Freight Data, NATFD），以及其他铁路与货运数据库。 文件下载
