Our impact

Reducing carbon emissions

Though farmed salmon has a low carbon footprint compared to other animal proteins, we have a responsibility to reduce emissions from our production and supply chain to reach the Paris Climate Agreement.

Grieg Seafood has set emissions reductions targets approved by the Science Based Target initiative as well below 2 degrees. The targets span both our own salmon farming operations (scope 1-2) and our supply chain (scope 3). The vast majority of our total emissions are linked to the feed, the biggest input factor in salmon farming operations, and freight.

How we will reach our targets

We are currently developing a systematic plan for our production and supply chain to reach our 2030 and 2050 targets. Meanwhile, we are engaged in different initiatives to develop technology with lower carbon emissions from our operations (scope 1-2). Our largest direct source of emissions is from the fuel that powers our boats, vehicles, and on-site electricity generators.

  • We are testing out a variety of new technologies to reduce the carbon footprint, such as replacing the diesel engines used at sites with battery packs or hybrid solutions.
  • We are also taking part in developing new solutions. For instance, in Rogaland, we have a test project on one of our farms with a wind turbine and solar panel.
  • Before making any investments, we evaluate their potential carbon emissions and environmental impact. This is an integrated part of the capex process.

Generally, our efforts to move away from poor sites and increase production on good and more suitable sites are also contributing to lower emissions from our operations, as we can use the energy more efficiently.

Moreover, our general efforts to work more preventatively and reduce our footprint on the environment also reduce emissions. For instance, working preventatively with sea lice and avoiding treatments, reduces our need to use wellboats and other equipment with high emissions.


We are also engaged in projects to reduce emissions from our supply chain (scope 3)

  • We have tested out methods to chill the salmon after harvesting, which made it possible to avoid ice in packaging and reduced the carbon footprint per kilo of packed salmon. We will invest in this equipment in the years to come.
  • We are partner to a project which replaces trucks with trains from Narvik in the north of Norway to Malmø in the south of Sweden, which reduces carbon emissions from part of the route to European customers. It is estimated that carbon emissions for this distance can be reduced by approximately 66%.
  • We are working to use our market power to halt deforestation, a contributor to climate change, connected to high risk feed ingredients in our supply chain. Read more about our policy and efforts here.
  • We are currently more systematically at how we can reduce our impact from feed ingredients.
  • We maintain a regular dialogue with our suppliers of feed, goods and services, and we discuss what they are doing to reduce their carbon emissions. Some of our suppliers already have their own carbon reduction targets. Going forward, we will encourage others to clarify their goals.

Where we are now

GREENHOUSE GAS EMISSIONS: Our greenhouse gas emissions are reported in accordance with the Corporate Accounting and Reporting Standard, developed by the Greenhouse Gas Protocol Initiative (GHG protocol), using the operational approach. 2017 is our baseline year, as this was our first year of complete and verified data. 
Scope 1 emissions are those that are directly emitted by Grieg Seafood’s activities and include emissions from the combustion of fossil fuels for generators, heating, and our own vehicles. Emissions are calculated on the basis of recorded energy cost using local energy prices. We also have a relatively small consumption of hydrofluorocarbons for cooling, which are included in Scope 1. All Scope 1 emission factors used are from DEFRA (Department for Environment Food and Rural Affairs, UK Government).

Scope 2 emissions are indirect emissions relating to third-party generation of the electricity we consume at our sites. Emissions are reported as location-based and market-based emissions in accordance with the GHG protocol. Location-based factors are from the International Energy Agency (IEA), using three-year rolling averages, while market-based factors are from RE-DISS (Reliable Disclosure Systems for Europe), apart from Canada which come from Green-E. Underlying data is collected from financial cost and on-site meters.

Our total greenhouse emissions increased by 25% in 2019 compared to 2018, while production increased by 11%. Measured as C02 equivalents per tonne harvested, the increase is 12%. Grieg Seafood is not content with the increase. The reduction plan we are currently working will outline a systematic approach to turn around this development and steer towards our targets and towards low-carbon operations.

In Rogaland, total emissions more than doubled from 2018 to 2019. The increase is due to a 55% increase in the harvested volume, and a considerable increase in the consumption of marine gas oil (MGO), which is mainly used for well boat services. Measured in terms of emissions per tonne, the increase from 2018 to 2019 is 49%.

In Finnmark, the decrease of both total emissions and emissions per tonne harvested is due to the reclassification of 3 299 tCO2 e of marine gas oil consumption from Scope 1 to Scope 3 based on a change in operational ownership at the start of 2019. Excluding this reclassification, total emissions increased by 16%, while the increase per tonne is 7%. The harvested volume rose by 9%. Measures taken to reduce greenhouse gas emissions during the year includes connecting three production sites to the electrical grid, and installing batteries on four production vessels, enabling diesel electric production. With the installation of heat pumps, on-shore electricity, and hybrid solutions, we were able to save 521 tCO2 e in 2019. At the same time, these measures increased our electricity consumption by 63 tCO2 e. The net reduction of these measures came to 458 tCO2 e.

In Shetland, the harvested volume decreased by 5%, while total emissions decreased by 4%. Emissions per tonne rose by 1%. In September 2020, Grieg Seafood decided to end its operations on the isle of Skye in Shetland, due to low synergies between the farms here and the main operations in Shetland. Transporting equipment between Shetland and Skye has increased carbon emissions, and with an end of these operations emissions are expected to decrease.

In BC, the 57% increase in total emissions is attributable to a substantial increase in the consumption of diesel to power our sites. Due to a 15% decrease in the harvested volume compared to the year before, emissions per tonne rose by 85%.
