Life Cycle Assessment
The Life Cycle Assessment (LCA) collection is a catalog and archive of data, tools, and resources that support LCA for agriculture and related areas of research. It is complementary to the USDA LCA Commons Life Cycle Inventory (LCI) database, and provides access to a wider range LCA data and tools.
Life Cycle Assessment (also known as life cycle analysis, or cradle-to-grave analysis) is a method of assessing environmental impacts associated with all stages of a product's life. For example, it measures impact from raw material extraction to materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. The goal of LCA is to compare the full range of environmental effects assignable to products and services by quantifying all inputs and outputs of material flows, and then assessing how these material flows impact the environment. This information is used to improve processes, support policy, and provide a sound basis for informed decisions.

The swine production datasets are the product of ongoing work by the University of Arkansas Center for Agricultural and Rural Sustainability, the United States Department of Agriculture, and the National Pork Board. The data documentation in this metadata record describes the project background and nomenclature,…
Data from: Greenhouse gas emissions from milk production and consumption in the United States: A cradle-to-grave life cycle assessment circa 2008
This carbon footprint study for fluid milk was commissioned in order to identify where the industry can innovate to reduce greenhouse gas (GHG) emissions across the supply chain.
To proactively meet the needs of the marketplace, the U.S. dairy industry is working together to further…
Unit processes represent wheat-wheat-fallow and wheat-wheat-rapeseed crop production simulations that illustrate using the IPCC (Tier 1) method for calculating changes in soil C and the roundtable on sustainable biomaterials (RSB) method for estimating N2O emissions in different locations for the use in modeling the crop production portion of the HRJ lifecycle. Data are archived in a SimaPro .csv file, which can be imported into various life cycle assessment modeling tools.
This unit process represents the generation of two co-products from forest or wood product mill operation residues using the Tucker Renewable Natural Gas (RNG) Thermochemical conversion process. The two co-products are a synthesis gas (syngas) and biochar (a form of charcoal made from woody biomass…
The USDA Life Cycle Assessment (LCA) Commons provides access to data, tools, and resources that support life cycle assessment for U.S. agricultural production and agriculturally derived products.
This document describes the preparation of datasets for the LCA Digital Commons that represent unit process/ gate-to-gate operations for the production of work (in MJ) by agricultural self-propelled equipment and fleets of agricultural self-propelled equipment. The data cover 19 types of fleets and over 200…
This document describes the preparation of datasets for the LCA Commons that represent unit process/ gate-to-gate operations for field operations (a.k.a. work processes e.g., soil preparation and planting for conventional tillage, applying fertilizer with incorporation) and farm implements (e.g., operation of moldboard plows, broadcast sprayers)…
This study examined average annual changes in soil erosion from rainfall and wind forces, and trends in soil organic carbon (SOC).
The diversity of geo-climatic land bases and potential feedstocks within the United States Central Great Plains (CGP) requires sustainable production that provides optimal resource…
