useeior: An Open-Source R Package for Building and Using US Environmentally-Extended Input-Output Models

Area of Science:

• Environmental science
• Economics
• Computer science

Background:

• Environmentally-extended input-output (USEEIO) models are crucial for life cycle assessment and environmental footprinting.
• Previous USEEIO model development faced challenges in data preparation and complex building processes.
• The useeior R package was developed to address these user challenges.

Purpose of the Study:

• To introduce the useeior R package as a solution for simplifying USEEIO model construction.
• To enhance the accessibility and usability of USEEIO models for researchers and practitioners.
• To improve the transparency, efficiency, and flexibility of the USEEIO modeling framework.

Main Methods:

• The useeior package provides convenient retrieval of economic and environmental data.
• It enables model building through simple configuration and optional hybridization specifications.
• Automated assembly of data and matrix calculations streamline the modeling process.

Main Results:

• Users can now build USEEIO models more efficiently with simplified data handling.
• The package automates complex data assembly and matrix calculations.
• Model results can be easily exported in various formats.

Conclusions:

• The useeior R package significantly improves the process of building USEEIO models.
• It enhances transparency, efficiency, and flexibility within the USEEIO modeling framework.
• useeior is a core component facilitating the delivery of updated USEEIO models.
