An snapshot of some of the tools being developed and used primarily for life cycle assessment but also for other purposes. The tools are used to process primary data, build models, and serve program office and other interfaces and external tools. Tools including StEWI, fedelemflo...

Communities and businesses continue to develop plastic recycling infrastructure including for the&nbsp;collection, sorting, purifying, and conversion into new recycled-content products.&nbsp; To promote sustainable infrastructure and systems a previous study analyzed polyethylene...

As efforts are made toward establishing a circular economy that engages in activities that maintain resources at their highest values for as long as possible, an important aspect is understanding the systems which allow recycling to occur. In this article a common plastic, polyet...

The USEPA provides databases that agglomerate data provided by companies or states reporting emissions, release, wastes generated and other activities to meet statutory requirements. Examples of these databases, often referred to as inventories, include the National Emissions Inv...

As part of defense acquisitions, Life Cycle Assessment (LCA) is a tool to assist in designing more sustainable systems—those that use fewer resources over the life cycle, have fewer impacts on human health and the environment, and thus have a lower total ownership cost. The objec...

This project was funded to advance life cycle assessment (LCA) capabilities at DoD by improving models and processes in three areas, automation of life cycle inventory, life cycle impact assessment, and environmentally-extended input-output (EEIO) modeling. Task 1 specified build...

A presentation to members of the Federal Scope 3 Community of Practice to provide a background on the Supply Chain GHG Emissions Factors first released by USEPA in 2020. Plans to update the factors for use in Federal Reporting are also described.&nbsp;

The datasets are comprised of greenhouse gas (GHG) emission factors (Factors) for 1,016 U.S. commodities as defined by the 2017 version of the North American Industry Classification System (NAICS). The Factors are based on GHG data representing 2019. Factors are given for all NAI...

The Supply Chain Greenhouse Gas Emission Factors for US Commodities can be used to approximate the greenhouse gas emissions associated with upstream activities for purchased goods and services. They were first released in 2020 along with a USEPA report of the same name. The lates...

Regional and multi-regional economic analyses require accurate data and information about intra- and inter-regional production and consumption. Subnational input&ndash;output (IO) tables capture industry- and region-specific production, uses and trade of commodities and serve as ...
