Example Projects

• USLCI Data Curation
  Franklin Associates, A Division of ERG is now serving as the data curator for the National Renewable Energy Laboratory's U.S. Life Cycle Inventory (USLCI) Database, which is a U.S. database that industry associations and other organizations can use to publish publicly available life cycle data. Such life cycle data can help life cycle assessment practitioners, researchers and the public understand the environmental impact of different supply chains. ERG provides quarterly updates and improvements to the database and works with organizations across the U.S. to release their data. The winter 2022 release included new datasets for plastic and steel product supply chains. If you have any data you would like to submit to the USLCI, please contact us at uslci@erg.com. The most recent release is available on the Federal LCA Commons in the NREL group repository: https://www.lcacommons.gov, and the update can also be downloaded from the USLCI GitHub Support Content page.
• Our Staff Co-Author Papers in Applied Sciences' Special Issue, "Advanced Data Engineering for Life Cycle Applications"
  Franklin Associates, A Division of ERG staff have been working with EPA and other collaborators on a series of papers for this special issue of Applied Sciences. These publications describe some of our novel life cycle assessment (LCA) tool development work in Python and R. This ecosystem of LCA tools and models enables robust and transparent calculation of supply chain environmental impacts, such as greenhouse gas (GHG) emissions. The tools mine and harmonize existing government data sources for use in life cycle applications, such as carbon footprinting and consumption-based GHG emissions inventories.

• Impact of Plastics Packaging on Life Cycle Energy Consumption & Greenhouse Gas Emissions in the United States and Canada, Substitution Analysis – January, 2014 (PDF)
  This Life Cycle Assessment (LCA) study was conducted for the American Chemistry Council (ACC) and the Canadian Plastics Industry Association (CPIA). The analysis focused on six major packaging categories: caps and closures, beverage containers, stretch and shrink film, carrier (shopping) bags, other flexible packaging, and other rigid packaging. In each category, the life cycle impacts of the current types and quantities of plastic packaging were compared to a scenario in which plastic packaging is substituted by alternative materials (e.g., paper and paperboard, glass, steel, aluminum, textiles, rubber, and cork). Separate substitution analyses were conducted for packaging in the US and Canada. While this study examines packaging impacts using a life cycle approach, the study is limited to an assessment of energy and GHG impacts and does not include an expanded set of environmental indicators.

• U.S. Life-Cycle Inventory (LCI) Database - 2002
  This was an extensive project to develop a publicly available U.S. database of LCI information that uses a common protocol for all unit processes. The protocol document for the project was completed in January 2002, and the data collection has been ongoing. The original project was a cooperative effort with Franklin Associates, Athena Institute, and Sylvatica. Franklin Associates developed many of the key data sets, including data for production and combustion of process and transportation fuels, grid electricity, plastic resins, primary and secondary aluminum, several metal transformation processes, and several commodity chemicals. The initial data sets were developed in 2003-2006. Updates for many of the original data sets have been submitted since then, and we continue to develop and submit data sets on behalf of industry clients. The database is now maintained by NREL and can be accessed at the LCA Digital Commons website.
