Onion refers to the vegetable known as a onion. The environmental impact information on this page includes greenhouse gas (GHG) emissions that occur as a result of the materials, production, packaging, and transport life cycle stages. It does not include the environmental impact of retail sale and consumer transport, storage, cooking, and disposal. The average (mean) carbon footprint or GHG emissions, attributed to the product life-cycle stages from material production to distribution, are 0.18 kg carbon dioxide equivalent (CO2e) per kilogram.[1]

The primary source for this environmental impact information is a meta-analysis published in the Journal of Cleaner Production. The data for onions was calculated from nine global warming potential (GWP) values published in seven life cycle assessment (LCA) studies. The GWP values for onions had a median of 0.17 kg CO2e. These GWP ranged from 0.06 to 0.37 and had a standard deviation of 0.11.[1]
