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.

Unit process data for agricultural self-propelled equipment version 1

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 types of self-propelled equipment datasets, representing the potential to prepare thousands of unit-process datasets by varying the operating and model years, applicable power ranges, and operating temperatures.
