Wheat refers to the cereal grain wheat. 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 0.51 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 wheat was obtained from 51 global warming potential (GWP) values published in 20 life cycle assessment (LCA) studies. The GWP values for wheat had a median of 0.52 kg CO2e. These GWP ranged from 0.18 to 1.1 and had a standard deviation of 0.17.[1]
