Environmental performance of farmed salmon

Did you know?

Understanding environmental performance starts with clear, measurable data. We look at specific indicators such as carbon footprint and feed use.

Measuring the environmental performance of farmed salmon

Producing food responsibly starts with understanding its impact. That is why we look at specific, measurable indicators such as greenhouse-gas emissions and feed use.

The figures below describe individual aspects of farmed salmon production. They are not intended to suggest that salmon has no environmental impact or performs better on every environmental measure.

Carbon footprint

The Global Salmon Initiative’s 2025 Sustainability Report reports a median carbon footprint of 0.6 kg CO₂e per typical serving containing 40 g of edible protein from farmed Atlantic salmon.

CO₂e, or carbon-dioxide equivalent, is a standard way of expressing the climate impact of different greenhouse gases in one comparable figure. This is a sector reference value, not a product-specific Bakkafrost lifecycle assessment.

Feed use

Feed is an important part of salmon farming. The biological feed factor shows how much feed is used to produce one kilogram of salmon biomass.

In 2025, Bakkafrost reported:

  • 1.106 kg of feed per kg of salmon in the Faroe Islands

  • 1.116 kg of feed per kg of salmon in Scotland

Using comparable data

Environmental figures can vary depending on the production system, location, data year, product boundary and calculation method. For that reason, comparisons are meaningful only when the same definitions and boundaries are used.
