1. Sustainable Forest Management

We always use wood from sustainable sources and promote sustainable forestry practices.

  • We never cut more than the forest
  • We refrain
    from forests with
    high biodiversity
  • We always take
    economic, social
    and environmental aspects into
  • We never cut more than the forest grows.
  • We refrain from forests with high biodiversity values.
  • We always take economic, social and environmental aspects into account.
Sustainable forestry makes it possible to use a single forest for many different purposes simultaneously:
  • Social

    Berry picking, hunting, recreation and various cultural and traditional uses of the land.

  • Environmental

    Protection of valuable species, habitats, landscapes, water and ways to secure biodiversity.

  • Economic

    Forestry activities creating livelihoods for forest owners, contractors, local entrepreneurs and forest companies.

Stora Enso ensures responsible wood sourcing by always knowing the origin of the wood and promoting sustainable forestry through forest certification.

2. Fibre and its traceability

Wood – our most important raw material for the production of pulp, paper, packaging and boards as well as wood products (such as sawn timber) – has several positive characteristics.

Wood is renewable and recyclable. Forests and wood are part of the climate solution:
  • Growing forests sequester carbon.
  • Wood and wood products bind carbon dioxide.
  • Wood products substitute other more carbon intensive materials (like concrete and steel) as well as fossil fuels.
  • Growing forests sequester carbon.
  • Wood and wood products bind carbon dioxide.
  • Wood products substitute other more carbon intensive materials (like concrete and steel) as well as fossil fuels.
The fibre we use comes from three different sources. Select a source to find out more.



Forests provide a versatile source of raw material for many different end uses. In Europe different industries have networked in a way that allows best and most efficient use of wood raw material; biggest and most valuable logs are used for construction purposes, whereas smaller trees are used in pulp and paper manufacturing. Chips, a by-product from sawmilling, also form a significant source of raw material paper mills. Small branches and harvesting leftovers are used to produce bio-energy.

We always know the origin of the wood that is used:
  • Our traceability systems cover 100% of the wood we use.
  • 100% of our purchased wood and pulp is covered by third party verification, such as Chain of Custody, Controlled Wood and ISO 14001.
  • How does forest certification work?

    Certification is a voluntary measure for forest owners to demonstrate responsible forest management. The forest certification systems are based on open stakeholder processes where a standard for responsible forest management is developed. A certified forest is regularly audited by an independent third party to ensure it complies with the forest certification standard. Since forest conditions differ worldwide, there is a need for more than one forest certification system.

    There are two main forest certification systems:
    • FSC®: Forest Stewardship Council
    • PEFC: Programme for the Endorsement of Forest Certification Schemes
  • The development of certification standards
    Stora Enso actively participates and promotes the development of forest certification standards nationally and internationally.
    • 75% of the wood in Stora Enso’s wood supply is certified even though only 10% of the world’s forests are certified.
    • As only 10% of the world’s forests are certified we make sure that also non-certified fibres come from sustainable sources: 100% of our wood can be traced back to its origin by our traceability systems. The traceability systems we use for all purchased wood and pulp, such as FSC Controlled Wood and PEFC Due Diligence System, are 100% verified by third parties.
  • What is a “Chain-of-Custody (CoC) certification”?

    The first link in the Chain-of-Custody is always a certified forest (Forest Management or FM certification), followed by one/several links in the “Chain-of-Custody” (CoC) of the same system (FSC or PEFC). Everyone who “takes ownership” has to be certified (incl. converters etc.).



Plantations are growing worldwide and will increasingly service the demand for industrial timber, pulp and paper, and wood bio-energy. They provide cost-effective raw material, as growth rates are up to ten times higher to the Northern hemisphere.

Tree plantations are often criticized for endangering biodiversity. However, the sustainability related impacts of plantations depend on which type of land-use they are replacing and how they are managed. Sustainable tree plantations are economically profitable, support the conservation of native ecosystems, and enhance local welfare.

Plantation management in Veracel

To find out more about how we manage our plantations, watch this video from our plantation in Veracel, Brazil.

Our sustainable plantation management principles
  • We never convert natural forests or protected areas into plantations
  • We recognize indigenous peoples’ legitimate rights to traditional land and land use
  • We respect the needs of local land use
  • We apply environmental and social impact assessments
  • We consider open and active dialogue with all stakeholders
  • We support various certification systems for plantations

Recycled fibre

Recycled fibre

Stora Enso is the third largest user of Paper for Recycling in Europe. The volume of Paper for Recycling used accounts for some 26% of our total fibre use in our paper and board production. Recycled fibre would not exist if we did not first have virgin fibre or primary fibre as it is sometimes called. Paper made of recycled fibres can typically be reused 5-7 times. It is suitable for products with a short life cycle like newspaper.

Langerbrugge Mill

This video takes you to our Langerbrugge Mill, which uses 100 % recycled fibre. The mill is located in an area where 80 million people live in a 300 km radius.

26% Of our total fibre is Paper for Recycling
We strive to use Paper for Recycling particularly in densely populated areas

Old newspapers and magazines are used at Langerbrugge Mill in Belgium (where they account for 100% of sourced fibre), Sachsen Mill (100%) and Maxau Mill (> 60%) in Germany, Hylte Mill in Sweden (50%) and Dawang Mill in China (100%).

  • Both recycled fibre and virgin fibre are needed

    While the manufacturing of recycled fibre based paper might consume less energy than producing virgin fibre based paper with chemical pulping, the fossil CO2 emissions of the latter will in most cases be much lower.

    Maximizing recycled fibre content for its own sake without considering product type, mill performance or mill location is neither environmentally nor economically viable. And not to forget: paper is based on renewable raw materials, and it is recyclable – which makes it fundamentally different from many other materials.

    71% Target recycling rate in Europe by 2015

Three different pulps we use

Chemical pulp

What is it used for?

The end-use of sulphite chemical pulp ranges from newsprint, printing and writing papers, to tissue and sanitary papers.

Sulphate (or Kraft) chemical pulp has widespread end-uses from graphic papers, tissue and carton board, wrappings, sack and bag papers and envelopes to other specialty papers.

  • How is it made?

    Logs are chopped into wood chips which are cooked with chemicals. This removes lignin and separates the wood into cellulose fibres. By-products, such as black liquor can be burnt for biomass energy. Modern pulp mills are net energy producers which can often supply power to the grid, or steam to local domestic heating plants.

Mechanical pulp

What is it used for?

Mechanical pulp is used mainly in newsprint and wood-containing papers, such as lightweight coated (LWC) and super-calendered papers.

  • How is it made?

    Wood logs are pressed against rotating stones. The heat generated by grinding softens the lignin binding the fibres, and the mechanical forces separate the fibres to form groundwood pulp. Mechanical pulping provides a good yield from the pulpwood because it uses the whole of the log except for the bark, but the energy requirement is high and can only be partly compensated by using the bark as fuel.

Recycled fibre

What is it used for?

De-inked pulps have mixed characteristics, as many different types of paper are included in Paper for Recycling.

This makes them particularly suited to applications such as newsprint and increasingly, packaging.

  • How is it made?

    PfR is made into slurry and contaminants are removed. Before the fibre can later on be used in graphical paper grades, in a next step printing inks have to be removed.”

The process of paper making

  • On the paper machine, water is added to the pulp.
  • Water is then removed on wire section by a mixture of gravity and suction. In this process, known as sheet formation, the fibres start to spread and consolidate into a thin mat.
  • This web of wet paper is then lifted from the wire mesh and squeezed between a series of presses where its water content is lowered to about 50%.
  • It then passes around a series of cast-iron cylinders, heated to temperatures in excess of 100ºC, where drying takes place. Here the water content is lowered to between 5% and 8%, its final level.
  • Throughout its passage from the wire mesh to the drying operation, the paper web is supported by various types of endless fabric belts moving at the same speed. At the end of the paper machine, paper is wound into reels.
  • The characteristics, appearance and properties of paper are supplemented and enhanced by their final treatments. These may be processes such as coating, calendaring, converting into more narrow reels or sheet cutting.
  • Environmental impacts

    As with any modern industrial process, pulp and paper production have an effect on the environment. That’s why a major priority for us is to reduce the environmental impact of our mills:

    Minimizing emissions

    We minimize emissions to air and water and impact on soil by using advanced control technologies and finding new ways to reuse and recycle waste.

    Maximizing resource efficiency

    We use raw materials, energy and other resources as efficiently as we can. This “more with less” approach is beneficial from both an ecologic and economic perspective.

  • Environmental targets

    Stora Enso has Group level environmental targets in the areas of sulphur (SO2) emissions, carbon dioxide (CO2), process water discharges, Chemical Oxygen Demand (COD) and waste to landfill. Our mills have certified environmental management systems in place which guarantee continuous improvement against these targets.

    We report on the environmental performance of our mills every year in Stora Enso’s Global Responsibility Report as well as in the mills’ Environmental Statements.

Depending on their locations, our products are transported by vessel, truck or rail to publishers, retailers, printing houses, merchants, converters and office suppliers.

The environmental impacts of logistical operations are an important factor when we evaluate different transport and supply chain solutions. Stora Enso actively promotes transport solutions with good environmental performance. Our transport chains are planned in line with our environmental policies and always analyzed for their environmental footprint.

End use & Recycling

Paper is turned into products that fit the end consumers’ purposes, be it as newspapers, magazines copy paper, books, envelopes etc.

The efficiency of the recycling of paper and packaging depends on the local infrastructure within national collection schemes and recovery systems. Consumers have a key role by recycling used packages, newspapers, magazines etc. Municipalities play a crucial part by providing the necessary infrastructure and adequate consumer information on the relevance of recycling.

All Stora Enso’s products are based on renewable raw material and do not contain harmful heavy metals or other dangerous ingredients. At the end of their life-cycle our products can be recycled or ultimately burned for bioenergy. Stora Enso actively promotes and participates in recycling schemes, and is one of Europe’s largest users of Paper for Recycling (PfR).

97% The utilization of waste generated at Stora Enso
Waste management

Stora Enso’s production processes generate various wastes, the vast majority of which are beneficially reused as residuals. Such materials include bark and wood waste, ash from energy production, lime solids from pulping processes, and wastewater treatment sludge. Many of these materials can be used for bioenergy production, for agricultural purposes, or for brick manufacturing and road construction. We are constantly looking for new and innovative ways to reuse materials that would otherwise end up as wastes. In 2014 our waste and residuals reuse rate across the Group was 98%.

4. Product & Environment Tool Kit

This section contains details on different certificates, ecolabels and paper profiles we use to demonstrate the sustainability of our products and processes. It also contains a list of the initiatives we closely support.



Why are certificates needed?

Different management systems are used to ensure that company policies turn into action. All management systems, be it quality, environment or occupational health and safety, require that relevant aspects are identified, targets set, practices to control relevant aspects are implemented and performance is regularly followed up. Management systems are therefore a powerful tool in ensuring continuous improvement of performance.

Our approach

All Stora Enso Printing and Reading mills are covered by third-party certified management systems for Quality (ISO 9001) Environment (ISO 14001), Occupational Health and Safety (OHSAS 18001) as well as PEFC™ and FSC® Chain of Custody. In addition to this, several of the mills also have third party certified Energy Management systems (ISO 50001 or EN 16001).

Certification is managed on a Business Area level. The so called “Multi-site certification” supports the further alignment of practices and sharing of information and experiences.

What are they?

Ecolabels are voluntary tools indicating that awarded products have a reduced environmental impact compared to similar products. The related criteria addresses the whole product life cycle and is defined in a way that only a certain percentage of products can meet them.

There are several national and international schemes. The most relevant for paper products are the “Blue Angel”, the “Nordic Ecolabel” and the “European Ecolabel”.

Our approach

Stora Enso Printing and Reading is applying all of these, according to customer needs – please see our Product Pages for more details!

Paper profile

Paper profile

What is it?

Paper Profile is a uniform declaration for presenting key environmental product information. It covers relevant environmental aspects related to pulp and paper production, including product composition and emissions, wood procurement and environmental management. Information presented on Paper Profiles is based on standardized common guidelines, making it possible to compare environmental aspects of different companies and products.

Our approach

Stora Enso Printing and Reading has Paper Profiles for all products. These are updated annually, and provided to customers on request.

Carbon Cycle and Carbon Footprint

Carbon Cycle and Carbon Footprint

The pulp and paper industry has a unique carbon cycle, from raw material generation to recycling of the end product. Sustainably managed forests remove carbon dioxide (CO2) from the athmosphere and store it as carbon. On average, a typical tree absorbs through photosynthesis the equivalent of one thousand kilos of CO2 for every cubic metre (m³) growth while producing the equivalent of 700 kilos of oxygen (O2). Carbon is further stored in paper industry products that provide a climate friendly alternative to many non-renewable materials. At the end of their life-cycle all our products can be recycled or ultimately burned into energy.

  • The Carbon Cycle
  • Carbon Footprint

    Carbon Footprint is used to describe the amount of greenhouse gases caused by an individual, an organization, a process, or a product.

    Stora Enso Paper has calculated the Carbon Footprints of its product segments, following the manual adopted by the European Association of Graphic Paper Producers, EURO-GRAPH to guide companies to prepare their data sets in line with the "Framework for the Development of Carbon Footprints for Paper and Board Products", developed by the Confederation of European Paper Industries, CEPI. These Carbon Footprints comprise direct and indirect CO2 emissions (associated with producing fibre, other raw materials and fuels, pulp and paper production, purchased and sold energy and inbound & internal transports) and biogenic carbon retained in the paper as leaving our mills, and thus removed from the atmosphere.

    Our approach

    The figures are presented in Carbon Footprint Fact Sheets, which we are happy to provide to customer on request. Whenever checking these Carbon Footprints against others, readers are supposed to ensure they will be looking at figures comparable from both scope/boundaries and calculation perspectives. They should also keep in mind that while the Carbon Footprint certainly is a relevant parameter, it is after all just one of several indicators characterizing the environmental performance of a product and the respective manufacturing processes!
