Proof of resilient and adaptable business
Looking at our performance in 2021, Stora Enso showed tremendous adaptability and resilience. We delivered record high results across our key business areas, overcoming macroeconomic turbulence and supply chain disturbances. Group revenue increased by 19% YoY while operational EBIT increased by 135% YoY. Our net debt ratio to EBITDA of 1.1 was below the target of less than 2. These are results to be proud of and a testimony of our continuous improvements and strategic progress.
Although uncertainties remain as new pandemic-related challenges continue to surface, the year carried many positives. We have found new ways of working safely to deliver products and services at the same high standard and pace as before the pandemic. By investing in a culture of learning and empowerment, we create a more agile business with enhanced customer intimacy. An increased demand for eco-friendly products, the hard work of our people, and our resilient business model have together supported our strong performance. I believe our achievements in 2021 provide a stellar example of a company striving towards one common goal: driving sustainable growth.
Sustainability is core to our strategy
Stora Enso is one of the world’s largest private forest owners. Sustainably managed, our growing forests have a positive climate impact, both as a carbon sink and through circular end-products. A flexible wood supply chain and accessibility is also fundamental for our innovation agenda. Global megatrends, with sustainability at the core, call for fossil-free materials and new applications for renewable and innovative materials. Our customers are increasingly aware of the advantages of products which are circular and climate friendly. It is our job to continue to deliver solutions to meet those needs. We foresee significant growth potential for our products within packaging, biomaterials innovations and building solutions, and this is where we focus strategic efforts and investments.
Strong demand for eco-friendly solutions
A strong demand for our packaging materials and solutions has been a major driver behind our solid 2021 results. In light of sustainability trends and the pandemic, the need for eco-friendly and hygienic food packaging is more important than ever. A shift in the packaging industry continues to accelerate, underlined by the rising demand for fossil-free, bio-based and recyclable packaging for everyday use. At the same time, consumer behaviour is changing rapidly with growing e-commerce related to increased home deliveries of retail goods, groceries and take-away food. All this, in turn, boosts market size and demand for sustainable packaging.
We are leading in sustainable consumer packaging with strong market positions, and are investing to meet a growing demand. Our liquid packaging board site in Skoghall, Sweden will add significant capacity following a EUR 97 million investment. Our EUR 350 million kraftliner conversion in Oulu, Finland started up in 2021, with profitability already ahead of schedule. In the beginning of 2022, we decided to move forward with a feasibility study for a second conversion in the Oulu site for production of premium carton board. Also, to improve recycling throughout Central and Eastern Europe, we have announced an investment to build a large-scale recycling facility in Poland together with Tetra Pak. The investment represents an important milestone towards a circular future.
