Fish and shellfish often compare favourably with meat, but a new regional assessment warns that there is no single climate footprint for Nordic seafood.
Large differences across the sector
A Nordic Council of Ministers report has examined greenhouse-gas emissions from fishing, aquaculture and seafood processing across the Nordic region. It finds substantial variations between countries, species, fishing methods and production systems, challenging the convenient assumption that every seafood product is automatically a low-carbon choice.
Fuel dominates fishing emissions
For wild-capture fisheries, fuel consumed by vessels is generally the principal source of emissions. The footprint consequently depends not only on what is caught but on the gear employed, the distance travelled, the condition of stocks and the amount of fuel required to land each kilogram of fish.
Feed is aquaculture’s central challenge
In fish farming, feed production accounts for the largest share of emissions. Ingredients, sourcing practices and feed-conversion efficiency can therefore be as important as the energy used at the farm itself, making innovation in alternative ingredients and better feed utilisation central to reducing the impact of Nordic aquaculture.
Seafood still compares well with meat
Most Nordic seafood products assessed in the report have a lower climate impact than land-based meat, particularly emission-intensive red meat. Yet the researchers caution against treating fishing and aquaculture as uniform sectors: poorly performing systems can differ considerably from efficient ones, while climate figures do not by themselves capture biodiversity, seabed damage, fish welfare or the condition of marine ecosystems.
A more informed Nordic food debate
The report offers policymakers, restaurants and consumers a more useful approach than simply categorising seafood as sustainable or unsustainable. For fishing nations including Norway, Iceland, Greenland and the Faroe Islands, it also shows that reducing emissions can support the long-term competitiveness of an industry central to exports, coastal employment and Nordic food culture.
