United States Environmentally-Extended Input-Output (USEEIO) Modeling Framework

A modeling framework for creating versions of the USEEIO model for estimating potential impacts of goods and services in the US economy in approximately 400 categories. This framework supports the Sustainable Materials Management program at US EPA (, but may also be useful for other purposes. It is built using a technique from life cycle assessment (LCA) that combines industry economic data with data on environmental releases and resources used. A background and description of USEEIO can be found in the following publication:

Yang Y, Ingwersen WW, Hawkins TR, Srocka M, Meyer DE (2017) USEEIO: A New and Transparent United States Environmentally-Extended Input-Output Model. Journal of Cleaner Production 158:308-318. DOI:10.1016/j.jclepro.2017.04.150

Installation and Use

Please see the wiki pages for instructions.


If you use this framework to develop models that are then published, please cite the use of the framework in the following manner. For general uses and referring the concept of this framework, cite:

Ingwersen, WW, Li, M, Yang, Y. United States Environmentally-Extended Input-Output (USEEIO) Modeling Framework. DOI: 10.5281/zenodo.1248954

For uses to build models for research, it's best to cite a specific release version. For example:

Ingwersen, WW, Li, M, Yang, Y. United States Environmentally-Extended Input-Output (USEEIO) Modeling Framework. (Version 0.1).DOI: 10.5281/zenodo.1248955
