This grant provides funding to construct and demonstrate a decision-support and visualization tool to examine the spatial distribution of supply chain environmental impacts and sustainability implications of producing many different goods and services in the United States. This work builds upon an existing 500-sector economic input-output model of the United States economy that has been used in conjunction with energy, environmental, and other data to show where in the supply chain impacts occur.Currently, most models in this domain provide only total national level estimates. This project will take the first steps to highlydetailed estimates in this project by providing regional and state-levelindicators. This method should also allow specific firms to compare their known supply chains with our estimates from each sector. Local analyses of economic changes typically omit the many indirect supply chain effects that occur. For example, the emissions related to automobile manufacturing extend far beyond the assembly plant. The result of this project will trace purchases among 485 economic sectors and identifypossible supplier locations among existing plants. The spatialdistribution of impacts, the location of supply chain and transportationroutes will be visualized in a Geographic Information System (GIS).Typical analyses include location of a new automobile assembly plant,infrastructure investment, shifts to ecommerce, growth in servicesectors, etc. Use of the analysis system is intended help reduceenvironmental effects of the regional economy, e.g., by reducingtransportation demands, moving suppliers closer to the productionfacilities, showing a firm's indirect impacts, etc. With free availability on the World Wide Web, we anticipate widespread use of the system.

这笔赠款提供资金，用于建设和展示一个决策支持和可视化工具，以研究在美国生产许多不同的商品和服务的供应链环境影响和可持续性影响的空间分布。 这项工作建立在现有的美国经济500个部门的经济投入产出模型，该模型已与能源，环境和其他数据结合使用，以显示供应链中的影响发生在哪里。 该项目将通过提供区域和州一级的指标，迈出高度详细的估计的第一步。这种方法还应该允许特定公司将其已知的供应链与我们对每个部门的估计进行比较。 当地对经济变化的分析通常忽略了许多间接的供应链影响。例如，与汽车制造有关的排放远远超出了装配厂。 该项目的结果将追踪485个经济部门的采购情况，并在现有工厂中确定可能的供应商位置。影响的空间分布、供应链的位置和运输路线将在地理信息系统（GIS）中可视化。典型的分析包括新汽车装配厂的位置、基础设施投资、向电子商务的转变、服务载体的增长等。使用分析系统旨在帮助减少区域经济的环境影响，例如，通过减少运输需求，使供应商更接近生产设施，显示公司的间接影响等，在万维网上免费提供，我们预计该系统的广泛使用。
