2 korsnäs AB Korsnäs AB is one of the world s leading producers of virgin fibre-based packaging material, primarily for consumer products. Production is conducted at the production sites in Gävle, Frövi and Rockhammar, all in Sweden. Production capacity amounts to 1.1 million tonnes of cartonboard and paper annually, with integrated pulp production. The range of products includes Liquid Packaging Board, Cartonboard, White Top Kraftliners and Sack- and Kraftpaper. The fibre content in Korsnäs packaging material is based on 100% renewable fibres. Korsnäs operations have an impact on the environment through forestry management, use of resources like energy, chemicals, water and air, and emissions to water and air. Korsnäs industrial operations are fully certified in accordance with ISO 9001:2008 and ISO 14001:2004, Quality and environment management FSC CoC/CW and PEFC CoC, FSC and PEFC Forest management SS , Ed 1, Energy management BRC/IOP, Hygiene management declarations of content clay coating for excellent printing results tcf-bleached fibres for good printing results and surface smoothness unbleached fibres and ctmp in two layers for stiffness and strength unbleached fibres for tensile strength Korsnäs Liquid lc Korsnäs Liquid LC is a coated packaging board (coated on the top side) made out of 100% virgin fibre.

4 Environmental Performance The environmental performance of Korsnäs Liquid LC 288 gsm is presented in the table below. The declared unit is one tonne (1000 kg) of the product delivered at the gate of an average converter/ customer in Europe. As additional information, the environmental impact is stated also per 1000 m 2.

6 Additional Environmental Information: Potential Environmental gain Waste minimisation All Korsnäs products are based on virgin fibres with high strength properties enabling packaging weight to be reduced. Recyclability and recovery Korsnäs Liquid LC is recoverable through material recycling and energy recovery in accordance with the material requirements in EN 13430:2004 and EN 13431:2004. Waste handling All board and paper products produced by Korsnäs meet the targets specified in the EU s waste management hierarchy within the EU Waste Framework Directive (2006/12/EC) as well as the essential requirements of the EU Packaging Waste Directive 94/62/EC. Biodegradable Korsnäs products are based on pulp consisting of cellulose, hemicellulose and some lignin which will be degraded by microorganisms in nature. The decomposition time required depends on several factors such as temperature, humidity, ph and microbiological activity. Uptake of carbon dioxide in growing forests Carbon stocks are increasing in Swedish forest ecosystems, mainly in the living biomass, due to the fact that the forest growth rate is higher than the harvest rate. The high growth rate is a result of efficient and sustainable forest management. The long-term forest management is to a large extent driven by the demand for round wood from the forest industry. The net sequestration (removal) of biogenic carbon dioxide is calculated based on the share of the net growth of the photosynthesis that is allocated to the board. Future scenarios for harvest rates in Sweden over the next 20 years conclude that the harvest rate will remain significantly lower than the growth rate. Note that that the system boundary settings used to calculate the net sequestration (removal) of biogenic carbon dioxide represent forest management and therefore differ from the product related boundary settings used elsewhere in the EPD.

7 Korsnäs climate programme Korsnäs is actively pursuing improvements to minimise the environmental impact. Through an extensive climate programme, Korsnäs has made and will continue to make major investments in resource optimisation in order to reduce the need for fossil fuels. Investments presently implemented or planned are: New evaporation plant in Gävle (2010) Exchange of fossil fuel in lime kiln to biofuel in Frövi (2010) Increase cooperation with the municipality of Lindesberg for local heating (2011) A joint venture with Gävle municipality for a new bioenergy plant to provide district heating (2012) References Eriksson, E., Karlsson, P-E., Hallberg, L., Jelse, K., Carbon Footprints of Cartons in Europe Carbon Footprint Methodology and biogenic carbon sequestration, IVL Swedish Environmental Research Institute, B1924, 2010 Jelse K. & Palm D., 2010, Life cycle assessment of Korsnäs virgin fibre-based packaging materials. IVL Swedish Environmental Research Institute definitions Upstream processes Forestry and production of raw materials and chemicals. Core processes Production at the board and paper mill including transportation of all materials (including wood) to the mill. Downstream processes Distribution of the product to an average customer in Frankfurt and waste management of transport packaging. Global warming potential Global warming is caused by increases in the atmospheric concentration of carbon dioxide (CO 2 ) and other Greenhouse gases that absorb and reflect heat. The global warming potential (GWP) is declared as CO 2 equivalents. Acidification Decrease of the ph value in terrestrial and water systems. Photochemical oxidant formation Hydrocarbons and volatile organic carbons (VOCs) contribute to ground level ozone formation, which has toxic effects on humans and vegetation. Hazardous waste Wastes such as sludge, mud, chemical waste, used oil, soot and radioactive waste from the production of nuclear power are classified as hazardous. PCR Product Category Rules specify Environmental Product Declaration requirements for a specified sector or product category, see Water use The total amount of water used for cooling and the production process at the board and paper mill. Net sequestration of biogenic CO2 in forests In photosynthesis, carbon dioxide from the atmosphere is removed and stored in the growing biomass. In Sweden, the forest growth rate is higher than the harvest rate, and the net removal of CO 2 from the atmosphere is here allocated to the harvested timber. The high growth rate is a result of efficient and sustainable forest management. verifications EPD Programme: The International EPD System Note: EPDs from different programs may not be comparable Registration no: S-P Date of publication: Validity: Valid within the following geographical area: Europe Data reference year: Production of pulp and paper/board 2008 Production of CTMP 2009 PCR review conducted by: The technical committee of the International EPD System, PCR moderator: Kristian Jelse PCR: Product category rules for processed paper and paperboard (CPC 3214), Version , Swedish Environmental Management Council. Independent verification of the data, according to ISO14025: Accredited or approved by: Det Norske Veritas (DNV) For more information: Eutrophication Eutrophication is the disturbance of the nutritional balance in the soil and waters due to an added amount of nutrition. In aquatic systems, this leads to increased production of biomass, which may lead to oxygen deficiency and fewer living organisms. Ozone depletion Substances such as freon that deplete the protective ozone layer in the stratosphere. 7
