North America Estimated Annual Truck CO2 Emissions 2035

This map shows the estimated annual truck 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 major roads are based on the North American Environmental Atlas‘ base layer. Major roads are divided, multi-lane, and limited access highways. The roads included are either those that connect major centers of population or selected frontier roads. Roads under construction are not shown. 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.The major source for data on truck movement was the FHWA’s Freight Analysis Framework (FAF and FAF2). In Canada, the information included for the estimation came from Transport Canada truck flows. In Mexico, the information that was used included truck flows from the Secretaría de Comunicaciones y Transportes (SCT) and 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 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卡车二氧化碳（CO₂）预估年排放量。二氧化碳排放量以千吨每公里为计量单位。该运输走廊为贯穿北美的多条运输走廊之一，其主要道路基于北美环境图集（North American Environmental Atlas）的基础图层制作。主要道路均为分隔式多车道受限通行高速公路，所纳入的道路要么连接主要人口中心，要么为选定的边境道路。在建道路未在本图中展示。 数据来源 本数据由德克萨斯交通研究所（Texas Transportation Institute, TTI）从多渠道收集，作为环境合作委员会（CEC）发布的《绿化北美运输走廊：挑战与机遇》（Greening North American Transportation Corridors: Challenges and Opportunities）论文的研究内容。卡车运输量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，排放量估算所用信息来自加拿大运输部（Transport Canada）的卡车流量数据。在墨西哥，所用数据包含墨西哥交通与通信秘书处（Secretaría de Comunicaciones y Transportes, SCT）及墨西哥交通研究所（Instituto Mexicano de Transporte, IMT）提供的卡车流量数据。其他数据来源包括美国交通统计局（Bureau of Transportation Statistics, BTS）的国家运输图集数据库（National Transportation Atlas Database, NTAD）与北美跨境货运数据（North American Transborder Freight Data, NATFD），以及其他货运数据库。文件下载
