Climate-friendly biomass


Our biomass is primarily wood pellets and wood chips derived from wood residues from sustainable forestry. Biomass has been essential to allowing us to phase out coal as a necessary energy source and serves as a supplement to wind and solar power.

Our wood pellets and wood chips are made from wood residues from sustainable production forests. The wood residues are of such low quality that they can’t practically be used to make buildings, furniture or floors. Wood waste is mainly tree tops, branches and sawdust from sawmills as well as discarded trunks that are diseased. The more wood used to make furniture and buildings, the more wood residues will be available to replace coal and gas for power generation and district heating in our CHP plants.

Wood from sustainable production forests

Sustainable production forests seek to produce wood as efficiently as possible. Production forests are regularly thinned to remove low-quality wood. Branches and tree tops are also cut off and left on the forest floor when trees are felled and taken to sawmills. This leaves considerable volumes of wood residues which we can use to produce green energy.

We only buy wood pellets and wood chips from suppliers offering biomass solely sourced from forest areas where there is ongoing reforestation, and the ecosystem and biodiversity are protected. To ensure that our suppliers comply with our sustainability requirements, we have implemented the Sustainable Biomass Program (SBP) certification system, under which independent third-party auditors monitor and certify that the suppliers fulfil our sustainability requirements.


Creating more green energy

We greatly reduce our impact on the climate when we replace coal and gas with wood pellets and wood chips from sustainable forestry. Trees are part of a natural cycle, absorbing and storing carbon dioxide when they grow, and releasing carbon dioxide when they later rot or are burnt. If the trees are used for timber or furniture, they store carbon dioxide for a long time, and the residual products from the timber production can be used to replace coal and gas. When new trees grow, they absorb the carbon dioxide emitted by converting the wood residues to energy. Coal and gas bind up a lot of carbon dioxide underground, and we should leave that where it is.

We have decided to completely phase out coal by 2023. Biomass has been essential to allowing us to phase out coal as a necessary energy source and serves as a good supplement to wind and solar power. A reliable energy supply needs an alternative to sources like wind power, for times when there is no wind.
