Rye refers to the cereal grain known as rye. The environmental impact information on this page includes greenhouse gas (GHG) emissions that result from the materials, production, packaging, and transport life cycle stages. The information doesn't include the GHG emissions from retail sale and consumer transport, storage, cooking, and disposal. The mean carbon footprint or GHG emissions, attributed to the product life-cycle stages from material production to distribution, are 0.41 kg carbon dioxide equivalent (CO2e) per kilogram.[1]

The primary source for this carbon footprint information is a literature review published in the Journal of Cleaner Production. The environmental impact data for rye was obtained from three global warming potential (GWP) values published in two life cycle assessment (LCA) studies. The GWP values for rye had a median of 0.38 kg CO2e. These GWP ranged from 0.36 to 0.49 and had a standard deviation of 0.07.[1]
