This product carbon footprint represents the amount (kg) of net greenhouse gas emissions (carbon dioxide, methane, nitrous oxides) in carbon dioxide equivalents (CO2e) into the atmosphere per amount (kg) of produced functional product. The carbon footprint is a measure of climate impact (impact category), expressed as the product’s global warming potential over 100 years, GWP ₁₀₀. The reduction of greenhouse gas emissions and concentrations in the Earth’s atmosphere mitigate global warming and climate change.

Life cycle assessments (LCA) of the product are made from cradle to gate (raw materials to packaged end-products) and include all fossil emissions, GWP _fossil, resulting from the product’s production. Biogenic emissions and removals, GWP _biogenic, including land-use, land-use changes and biogenic methane, are calculated and reported separately. When product-specific values are not presented, biogenic emissions and removals are disregarded or regarded as having net-zero climate impact (emissions = removals). Thus, the product carbon footprint represents carbon footprint (fossil), unless otherwise stated.

For scale, the cradle-to-gate carbon footprint values of common food products at usual points-of-purchase are estimated to have a range of approximately 0-40 kgCO₂e/kg. Deviations are possible.
