Chestnut refers to the nut of the chestnut tree. 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 0.43 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 authors of the meta-analysis located one global warming potential (GWP) value for chestnuts in one life cycle assessment.[1]
