Stora Enso has reached a significant environmental milestone as its Lahti production site no longer requires an environmental permit following a decision by the local authorities. The achievement highlights the company’s long-term commitment to sustainability, operational excellence, and continuous environmental improvement, reinforcing its position as one of the global leaders in renewable materials and responsible manufacturing.
The decision comes after years of strategic investments and environmental initiatives aimed at reducing the site’s environmental footprint while enhancing operational efficiency. Through a combination of advanced technologies, process optimisation, and infrastructure upgrades, the Lahti facility has demonstrated measurable progress across several key sustainability indicators.
One of the most notable achievements has been the replacement of natural gas with electric steam boilers, resulting in a reduction of more than 70% in direct greenhouse gas emissions at the site. The transition represents a major step in Stora Enso’s broader decarbonisation strategy, supporting the company’s ambition to reduce emissions throughout its production network and contribute to global climate goals.
In addition to significantly lowering emissions, the Lahti site has implemented several technical improvements that have enhanced its environmental performance. Noise levels have been substantially reduced through equipment modernization and engineering upgrades, creating a better environment for both employees and the surrounding community. Wastewater quality has also improved through the introduction of advanced ultrafiltration technology, enabling more efficient treatment and cleaner water discharge.
The removal of the environmental permit requirement reflects the confidence of local authorities in the site’s consistently high environmental standards. Rather than simply meeting regulatory requirements, the achievement demonstrates how sustained investment, innovation, and continuous improvement can enable industrial facilities to exceed compliance expectations while delivering long-term environmental value.
The Lahti facility plays an important role within Stora Enso’s Packaging Materials business, producing renewable and fiber-based packaging solutions that support the transition away from fossil-based materials. As demand for sustainable packaging continues to grow across global markets, the company’s ongoing investments in cleaner production technologies reinforce its commitment to responsible manufacturing and circular economy principles.
Environmental performance has become an increasingly important competitive factor for manufacturers worldwide. Across the forest products and packaging industries, companies are accelerating investments in electrification, energy efficiency, water conservation, and emissions reduction to meet evolving customer expectations and international sustainability targets. Stora Enso’s latest achievement reflects this broader industry transformation while demonstrating how continuous operational improvements can generate measurable environmental benefits.
Looking ahead, Stora Enso has emphasized that the work at the Lahti site will continue. The company remains focused on further reducing environmental impacts, improving resource efficiency, optimizing production processes, and strengthening sustainable operations across the facility. By maintaining a culture of continuous improvement, the company aims to build on its progress and support its long-term climate and sustainability objectives.
The latest milestone underscores that meaningful environmental progress is achieved through consistent action over time. By investing in cleaner technologies, modern production systems, and responsible resource management, Stora Enso continues to demonstrate how industrial innovation can drive both environmental performance and operational resilience, setting a strong example for the global forest products and packaging industries.
“What if the materials we depend on every day could be reimagined? What if the way we produce, package, and build could help solve some of the urgent global challenges? As megatrends shift and evolve – from climate change to urbanisation – the need for smarter solutions increases. This is where trees and the materials they enable become part of the answer.”
At Stora Enso, this is at the core of their story. The company is a of a global shift already underway. A shift from finite resources to renewable ones. From linear systems to circular solutions. Because the choices they make today don’t just shape products. They shape industries, communities and the world we live in tomorrow.
