Do you want to know more about Stora Enso?
Efficient use of resources is essential in combatting climate change and enabling the green transition. We continuously improve energy efficiency and strive towards energy self-sufficiency and low carbon solutions at our sites.
Stora Enso has a proactive and holistic approach to decrease the use of fossil fuels and reduce direct and indirect fossil CO2 and other emissions. This can create new business opportunities and help manage the Group’s costs and risks. With access to renewable biomass and fossil free electricity, we are well positioned to contribute to the green transition. The majority of the fuel we use is renewable biomass fuels from forest and process residuals which means that the proportion of carbon-neutral CO2 emissions of total emissions is high.
Our production units systematically work to improve energy efficiency, supported by a third-party certified ISO 50001 energy management system. The sites generate and distribute energy to local district heating systems and industrial partners largely based on residuals from harvesting operations and production processes.
Stora Enso's central energy and water efficiency investment fund is an important tool to implement energy savings effectively. In 2022, the fund was earmarked for energy and water efficiency investment projects at our units.
Reducing emissions to air
Stora Enso’s atmospheric emissions result primarily from the combustion of fuels for energy generation and from transportation. Emissions include CO2, sulphur dioxide (SO2), nitrogen oxides (NOx) and fine particles. CO2 contributes to climate change while SO2 and NOx emissions affect air quality and can cause acid rain and soil acidification. We work to reduce air emissions from point sources using advanced technologies such as scrubbers and boiler process control systems.
Board, pulp and paper production processes are the most energy intensive phases in Stora Enso’s value chain which makes it essential for the units to have access to reliable and sustainable energy supply at a reasonable cost.
Stora Enso’s energy supply is managed under long-term contracts, direct market access through energy exchanges, combined heat and power production, and shareholdings in power generation companies such as Pohjolan Voima Oyj and Teollisuuden Voima Oyj in Finland.
Most of Stora Enso’s production processes are energy intensive, and the Group’s energy efficiency target is to achieve at least 1.1% annual energy savings by 2030.
