A major producer and user of renewable energy

Metsä Group’s pulp mills are among the largest producers of renewable energy in Finland.

Production with renewable bioenergy


Fossil free energy constitutes 87% of the energy used in Metsä Group’s production. Nationally, we are a major producer of renewable energy: Metsä Group produces over 15% of the renewable energy in Finland. In 2021, we produced a total of 28 TWh of renewable energy of which a majority, 25 TWh, was used in our own production.

Our investments in biobased renewable energy and improved energy efficiency have enabled us to reduce our fossil carbon dioxide (CO₂) (Scopes 1 and 2) have declined by 22% per tonne produced compared to 2018. We produce renewable energy from logging residue, such as branches and treetops, sawdust and bark from sawmills, as well as production side streams.

The energy self-sufficiency rate of our pulp mills is 140%, and they are among the largest producers of renewable energy in Finland. In addition to our own production, we supply bioenergy in the form of district heat to local communities and electricity to the grid.

Investments in renewable energy

In recent years, Metsä Group has made significant investments in bioenergy, which have further increased the share of bioenergy in our operations. Read more about our recent on upcoming investments.

A major supplier of energy to replace fossil fuels

In addition to its own energy production, Metsä Group is one of the largest suppliers of wood-based biomass in Finland. We enable customers to replace fossil fuels, with customers all around the country. Metsä Group supplies the equivalent of 3 TWh of biomass for bioenergy production that can replace up to 0.8 million tonnes of fossil carbon dioxide emissions per year. Our direct fossil CO2 emissions were 652,000 tonnes in 2021.

Focus on energy efficiency

As well as increasing the share of renewable energy, we are focusing on energy efficiency. We monitor the development in our mills' energy efficiency with an energy efficiency index. It is calculated as a ration between all the electricity, heat and fuel used by production to the volume of production. In 2021, the index was 99.8. Our goal is to have an index of 90 in 2030.  Improving energy efficiency is an important element in all of our major production investments.
