Cherishing carbon sinks

​Our operations are based on the versatile use of recyclable and renewable wood biomass, combined with innovation, efficiency and sustainability. Our wood raw materials come from responsibly and sustainably managed forests, which we nurture so that they can continue to act as effective carbon sinks.


​Growing trees maintain their vitality through photosynthesis. For this process, trees require carbon dioxide, light, heat, water and chlorophyll.  The process produces carbohydrates, such as sugars and starch, as well as oxygen as a by-product. Trees bind carbon and can thus act as carbon sinks throughout their growth. Wood-based products also bind carbon throughout their entire lifecycle.

We plan to use forests in a sustainable manner so that the age structure of the forests remains versatile both at local landscape and regional levels, and so that they can act as effective carbon sinks throughout their growth. An essential part of maintaining the vitality of the forests is to get a new generation of trees to start growing soon after harvesting.

We grow seedlings from seeds suitable to various regions at our own tree nursery in Joroinen. The tree nursery stores the seeds in controlled conditions and ensures that UPM and our contract customers have access to high-quality seeds and seedlings to be sown or planted in forests. By tending our seedling stands in a timely manner, we can ensure the growth and vitality of our forests. 

An essential part of the responsible use of wood is to effectively make use of all parts of the wood, production side streams and production residues. We aim to reduce the carbon footprint of our products throughout their lifecycle. We take into account the impacts of the raw materials and production processes on our products and the environment, and strive to minimise any adverse effects already at the planning stage. We promote resource efficiency: our aim is to make more with less.

Our wood-based products retain the carbon bound in wood throughout their lifecycle, which can vary from a few months to hundreds of years. Paper products are among the products with the shortest lifespans, but the lifecycle of the wood fibres used in paper products often continues thanks to recycling: Wood fibres can be reused up to seven times. Products made from renewable materials are increasingly replacing products made from non-renewable materials.
