USEEIO v2.0 is an environmental-economic model of US goods and services that can be used for life cycle assessment, footprinting, national prioritization, and related applications. This paper describes the development of the model and accompanies the release of a full model dataset as well as various supporting datasets of national environmental totals by US industry. Novel methodological elements since USEEIO v1 models include waste sector disaggregation, final demand vectors for US consumption and production, a domestic form of the model that can be used to separate domestic and foreign impacts, and price adjustment matrices for converting outputs to purchaser price and in various US dollar years. Improvements in modeling national totals of industry and environmental flows are described. The model is validated through reproduction of national totals from input data sources and through analysis of changes from the most recent complete USEEIO model that can be explained based on data updates or method changes. The model datasets can all be reproduced with open source software packages.
USEEIO v2.0 是一个美国商品和服务的环境经济模型，可用于生命周期评估、足迹分析、国家优先排序和相关应用。本文描述了模型的开发，并随附了完整模型数据集以及按美国行业划分的各种国家环境总量支持性数据集。自 USEEIO v1 模型以来，新颖的方法元素包括废物部门细分、美国消费和生产的最终需求向量、可用于分离国内和国外影响的国内模型形式，以及用于将产出转换为购买者价格和各种美元年的价格调整矩阵。描述了改进工业和环境流国家总量建模的方法。通过从输入数据源重现国家总量以及通过分析基于数据更新或方法更改可以解释的最新完整 USEEIO 模型的变化来验证模型。可以使用开源软件包重现所有模型数据集。
