Global Production1,2
Global production of farmed salmon and livestock primary products, measured in tonnes.

Sheep
Carbon Footprint3
A carbon footprint measures the total greenhouse gas emissions caused directly and indirectly by the production of a product. Carbon footprint is measured in kilograms of carbon dioxide equivalent (kgCO2eq) per typical serving (40 g) of edible protein of the product. Data are median values.

Pork
Beef
Lamb
Land Use4
The amount of land needed to produce 100 g of edible protein.
Feed Conversion Ratio5
Feed conversion ratio (FCR) measures the productivity of different
protein production methods. It demonstrates the kilograms (kg) in feed need to
increase the animal’s bodyweight by 1kg. A lower FCR represents a more efficient use of feed resources.
Protein Retention5
Protein retention describes the gain in edible protein as a percentage of the protein intake from food. It is calculated as a percentage (grams protein in edible portion / grams protein in feed).

Calorie Retention5
Calorie retention describes the gain in edible calories as a percentage of the calorie intake from feed. It is calculated as a percentage (calories in edible portion / calories in feed).

Edible Yield6
Edible yield is calculated by dividing edible meat by total body weight.
