Corn refers to the vegetable known as corn or maize. The environmental impact information on this page includes greenhouse gas (GHG) emissions that are caused by the materials, production, packaging, and transport life cycle stages. The information omits the carbon footprint of retail sale and consumer transport, storage, cooking, and disposal. The average or mean carbon footprint or GHG emissions, attributed to the product life-cycle stages from material production to distribution, are 0.63 kg carbon dioxide equivalent (CO2e) per kilogram.[1]

The main source for this carbon footprint information is a meta-analysis published in the Journal of Cleaner Production. The data for corn was calculated from six global warming potential (GWP) values published in six life cycle assessment (LCA) studies. The GWP values for corn had a median of 0.47 kg CO2e. These GWP ranged from 0.4 to 1.38 and had a standard deviation of 0.38.[1]
