Energy efficiency
All Metsä Group’s production units are overseen by an energy efficiency manager and a management system that complies with the ISO 50001 standard.
Investments drive energy efficiency forward in leaps. Key investments in recent years to increase energy efficiency include, for example, new Kemi bioproduct mill, development program of the Kemi board mill and new steam turbine and the associated generator cooling water recovery at Kyro board mill. The positive effects of the new capacity on energy efficiency have not yet been realized in the sawmill, pulp and board businesses due to the ramp-up phase in production, production restrictions due to weak demand and the political strikes at the beginning of 2024.
Above all, results are achieved by continuously developing operations in the daily routines of mills. Energy efficiency measures are reported annually. In 2024, a total of about 60 energy efficiency measures were reported, of which technical changes to improve energy efficiency were made in several mills.
Fossil-free production
To achieve this goal, Metsä Group has a plan for investments and measures to replace fossil fuels and purchase electricity from fossil-free sources. In addition, Metsä Group invests in the efficient use of energy, water and materials.
In recent years, key investments in achieving fossil-free production have been the Kemi bioproduct mill, the renewal of the recovery boiler and turbine at the Husum pulp mill, the renewal of the turbine at the Kyro board mill, and the ongoing renewal and expansion of the Mariestad tissue paper mill.
Future investments include the electrification of boilers and processes that still use fossil fuels.
Logistics emissions
Emissions are reduced by replacing fossil fuels in transport with fossil-free alternatives. In addition, logistics emissions are continuously reduced through efficient route planning, minimizing transport distances and optimising filling rates.
To achieve the goal, joint emission reduction targets have been agreed with logistics suppliers, such as VR, Royal Wagenborg and Navalis Shipping.
Fossil-free raw materials and packaging materials
For most raw materials, both long-term and short-term development work towards the introduction of fossil-free alternatives has been initiated. Reducing the use of fossil materials also helps to reach the target. For example, in 2024, Metsä Group managed to reduce the amount of plastic without compromising the barrier properties of the Husum mill's PE-coated folding boxboard.
Three areas have been selected for the Group-wide strategic R&D function and procurement development programme to support the achievement of the target:
- Long-term laboratory and pilot-scale studies and mill test runs with new raw materials.
- Mill-scale packaging material experiments, and monitoring the needs of customers and global markets to introduce protective and sustainable packaging based on recycled and bio-based raw materials.
- Developing procurement systems to reliably and accurately monitor the share of fossil-based raw materials.
Mechanical wood products
Wood products are versatile for various long-term uses, such as construction. The carbon stored in wood products acts as an artificial carbon store as long as the material is in use. Light, strong and uniform quality wood products are also excellently suited for element production that improves the efficiency of construction, as well as for hybrid construction that utilizes different building materials. The production capacity of wood products is increased at the new Äänekoski Kerto LVL mill and by optimizing the production of the Rauma sawmill.
Metrics by the end of 2030:
10 units improvement in energy efficiency from 2018 level
0 tonnes of fossil carbon dioxide emissions (Scopes 1 and 2, market-based)
-30%/tkm Greenhouse gas emissions from logistics purchased by Metsä Group from 2022 level (Scope 3, category 4)
100% fossil-free raw materials and packaging materials excluding wood and purchased pulp
+ 30% mechanical wood products from 2018 level
