Climate emission reduction iniatives

What does it mean for Lerøy To be sustainable?

 

ENVIRONMENT -  We must take care of the environment. All activity affects the environment, but we must ensure that the environment will return to its original state after use in order to be able to operate in an eternal perspective.

Social - we must look after the people and the local environment. Ensure that human rights are safeguarded for employees who are involved directly or indirectly in our value chain and contribute positively to the local environment around us.

Governance – We must comply with laws and regulations, protect our reputation and operate profitably.

    Sustainability wheel

We will reduce our greenhouse gas emissions by 46% by 2030 and net zero in 2050

In order to reach our climate target, we have identified 3 main projects that will reduce climate emissions in LSG, the identification of main projects is based on our most significat emission areas.

Sustainable fish feed

Raw materials for fish feed are a strong driver in relation to greenhouse gas emissions and a part of scope 3 purchased goods and services, which resulted in 527 804,8 tCO2e in 2022. Lerøy therefore wants to prioritize raw materials that contribute to reaching our climate target without compromising biodiversity and other important ESG targets.

  • Use and develop feed ingredients such as microalgae and insect meal that have a low climate footprint
  • Increased utilization of offcuts and residual raw material from the wildcatch segment
  • Ocean forest, production of macroalgae, mussels and low-trophic species

Transport

Upstream transportation and distribution is our second largest greenhouse emisson source, and resulted in 433 909,4 tCO2e in 2022. Transportation of produced products to customers is the largest contributar, prioritization of optimalization of transport weight and gain technology to be able to choose more climate efficient transport is essensial.

  • Developed a climate calculator for air transport showing the most climate-efficient routes​
  • Reduce transport weight by 20% by replacing wet ice with dry ice as a cooling medium​
  • Increase the degree of processing – higher utilization of residual raw material

Alternative fuel sources

Leroy is part of different innovation program how to create alternatives to fossile fules like MGO. Our total scope 1 emissions in 2022 was 169 913 tc02e. In the wildcatch segment; Lerøy Havfisk is a part of an innovation program how to use green ammonia to reduce the dependency of MGO, in addidtion the farming segment has almost finisalized electrification of farm locations.

  • Green Shipping Program - development of alternative low-emission fuel sources​ i.e ammonia
  • Mixing biofuel into Marine Gas Oils (MGO) without engine changes​
  • Streamlining operations and fishing gear to use less MGO​
  • Electrification of fleets, well boats and workboats

Electrification of fleets, well boats and workboats

The world's largest shore current system for well boats is ready for use at Hitra. The investment is one of many measures we are taking to achieve the company's goal of reducing climate emissions by 46% by 2030. Our main goal is to create the world's most efficient and sustainable value chain for seafood, says Harald Larssen, general manager of Lerøy Midt.

Lerøy Midt has chartered the wellboat Gåsø Høvding, which has been built to run all systems on board completely electrically for direct delivery of salmon to our slaughterhouse on Jøsnøya in Hitra. The well boat is the world's largest with more than twice the well volume of normal well boats. The well boat is owned by Frøy Rederi AS, which has invested large sums in the system for electric operation. The boat must be christened on the same day and in the same place as the opening of the shore power plant.

With the investment in the high-voltage shore power plant, Lerøy Midt has the potential to significantly reduce nitrogen oxide (NOx) and several thousand tonnes of CO2 equivalents annually. - We save emissions, and it is a more sustainable alternative than using conventional fuel, says project manager Sven Amund Fjeldvær in Lerøy Midt.

The project is a close collaboration between Lerøy Midt AS as the client, Frøy Rederi AS which owns the wellboat and Nord Trøndelag electricity utility (NTE) which designed and built the shore power plant. Sven Amund wants to highlight the good and close collaboration and says that it would not have been possible without the collaboration partners, subcontractors and authorities.

In addition to NTE and Frøy Rederi AS, Enova has been involved and taken up to 40 per cent of the budgeted investment costs, which has made it possible to carry out the project.

Gåsø Høvding, like other well boats, is manned around the clock, so the crew in particular will be able to enjoy the electric silence. - It will improve the working conditions and the working environment for everyone involved, both those on board and us who work on Jøsnøya .In addition to the actual transport of salmon from the cages to slaughter, the size of the boat allows the entire biomass from a cage to be handled in one load. If, for example, salmon lice treatment is necessary, the well boat can be filled with fresh water that it can produce itself and treat the entire cage in one operation. The treatment is a gentle treatment against this parasite.The well boat is equipped with today's most modern equipment, which means that the salmon have as good conditions on board as they have in a cage in localities.

Power from land

The Group has established different revolutionary measures in order to reduce environmental impact; from obtaining power from land, hybrid fleets, floating  solar cells, to electric working boats.

Wherever it is possible, the Group seeks to use electricity sourced from land-based powerlines  instead of electricity from generators at each production site.

Power from land usually makes good overall  economic sense.

Power from land results in:

  • Reduced emissions
  • Less noise
  • Good economy
  • Less maintenance

The further development of power from land should entail a degree of overcapacity, thus enabling any future electrified boats to be recharged.

More than 80 % of our sites now run on power from  land, on remaining sites where the infrastructure is insufficient for land-based electricity, Lerøy Seafood Group is developing hybrid solutions that allow for up to 30% more efficient use of fossil fuels at each site. 

The various measures require technological  development and a high level of expertise, and in many ways, they represent a breakthrough in the industry.

Solar panels provide fish with a less energy footprint


Lerøy Kjærelva is a RAS facility, which means that 99 per cent of the water is reused. Because you use so little water resources, it is environmentally friendly and sustainable. The RAS technology still requires more electricity to purify the water used. This means that fish from RAS facilities have a higher energy footprint than traditional farming.

The solar panel, which is placed on a 14,000 square meter roof, provides an annual electricity saving of approximately 1.2 gigawatt hours, which is equivalent to the annual electricity consumption of approximately 75 households!
