Cashew nut refers to the seed of the cashew 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. 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 1.55 kg carbon dioxide equivalent (CO2e) per kilogram.
The principal source for this environmental impact information is a systematic review published in the Journal of Cleaner Production. The information for cashew nuts was calculated from four global warming potential (GWP) values published in three life cycle assessment (LCA) studies. The GWP values for cashew nuts had a median of 1.44 kg CO2e. These GWP ranged from 1.06 to 2.27 and had a standard deviation of 0.85.
The table below lists products in the nut category with the lowest total GHG emissions.
|Product||Total (kg CO2e)|
|Chestnut (1 kg)||0.43|
|Peanut (1 kg)||0.87|
|Hazelnut (1 kg)||0.97|
|Pistachio (1 kg)||1.53|
