Rice refers to the cereal grain known as rice. 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. The information 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 2.66 kg carbon dioxide equivalent (CO2e) per kilogram.[1]

The principal source for this environmental impact information is a systematic review published in the Journal of Cleaner Production. The information for rice was calculated from 27 global warming potential (GWP) values published in 12 life cycle assessment (LCA) studies. The GWP values for rice had a median of 2.55 kg CO2e. These GWP ranged from 0.66 to 5.69 and had a standard deviation of 1.29.[1]
