Calculating the carbon footprint of paper and paperboard

Climate change is an increasingly important issue, and every product has an impact. To support climate-smart decisions, Holmen calculates the carbon footprint of its paper products from a life cycle perspective. These calculations facilitate the comparison of emissions between different types of paper products and suppliers.

The results are updated annually and help identify where emissions occur in the value chain. This enables us to take targeted action to reduce our impact. Emission levels are presented in kilograms of fossil carbon dioxide per tonne of product and vary depending on grade, mill and production setup.

How Holmen calculates carbon footprints

Holmen’s carbon footprint data is calculated using a recognised industry standard that covers emissions from forest to delivery. This includes:

  • Forest management and raw material sourcing
  • Production processes and energy use
  • Transport and logistics
  • End-of-life assumptions

Our calculations are based on actual production data and reflect emissions from cradle to gate. We report both fossil and biogenic emissions in kilograms of CO₂ equivalents per tonne of product. All figures are verified by independent third parties and updated regularly to reflect changes in energy mix, process improvements and logistics.

CEPI ten toes methodology

The carbon footprint declarations for our products are calculated by external consultancy firm AFRY in accordance with the CEPI framework of ten toes. The framework show you carbon dioxide emissions during different parts of the chain.

  • Toe 1: Biomass carbon sequestration in forests
  • Toe 2: Biomass carbon in forest products
  • Toe 3: Biomass greenhouse gas emissions from forest products manufacturing facilities
  • Toe 4: Greenhouse gas emissions associated with producing fibre
  • Toe 5: Greenhouse gas emissions associated with producing other raw materials and fuels
  • Toe 6: Greenhouse gas emissions associated with purchased and sold electricity, steam, heat and hot and cold water
  • Toe 7: Transport-related greenhouse gas emissions
  • Toe 8: Emissions associated with product use (for example printing)
  • Toe 9: Emissions associated with product end-of-life
  • Toe 10: Avoided Emissions
