Hazelnut refers to the nut of the hazel 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 0.97 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 hazelnuts was calculated from two global warming potential (GWP) values published in two life cycle assessment (LCA) studies. The GWP values for hazelnuts had a median of 0.97 kg CO2e. These GWP ranged from 0.43 to 1.5 and had a standard deviation of 0.76.
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|
