Post-Doctoral Research Program

Globalizing the USEEIO model

Project number:LMMD-04-03-2019-02
Division:Land and Materials Management Division
Branch:Materials Management Branch
Brief description of research project:USEEIO is a national model of ~400 goods and services which Office of Research and Development (ORD)/National Risk Management Research Laboratory (NRMRL) continues to develop and underlies the primary analytical tools in support EPA’s Sustainable Materials Management (SMM) program. The EPA SMM program evaluates materials and environmental impacts related to US production and consumption activities. A significant proportion of US industry and final consumption is from imports. The production of these imports is not modeled with global data reducing the accuracy of consumption-based estimates. Additionally, EPA Office of Land and Emergency Management (OLEM) has a strong interest in integration of global inorganic (IO) and material flow efforts into the EPA’s SMM analytical framework, however this is limited by the single country structure of USEEIO. Furthermore, OLEM has a strong interest in tracking materials in US exports and their potential for environmental and human health impacts, for instance recovered plastics and electronics shipped in large quantities to East and South Asian countries, but consequences of such trade cannot be assessed yet by USEEIO. There are existing global models of the same type (EEIO) as USEEIO called multi-regional input-output (MRIO) models, that model environmental and material burdens of production in other countries and world regions. Adaptation and linkage of one of these models to USEEIO would present an ideal solution for modeling imports, however, it presents a number of research challenges, not limited to reconciliation of methods for estimating environmental releases and material use, impact assessment methods, different good and service classification schemes, trade systems, currency and price adjustments, as well as technical issues of integrating an MRIO from another code base into the USEEIO R and Python-based Modelling Framework. The desired candidate will work closely with the USEEIO team to chart a path forward for MRIO model integration, then work with the team to integrate the MRIO in an automated way through extension of the USEEIO Modeling Framework. The candidate will interact with researchers representing the selected MRIO model to assure proper interpretation and integration of the MRIO. The candidate will assess in depth various research problems associated with MRIO linkage and publish these results in the peer-review literature.
