The carbon footprint is a key climate impact indicator. It is used to measure the climate impact of governments, private companies, individuals and products alike. By measuring the carbon footprint, a company can see the volume of greenhouse gas emissions resulting from a product or activity.
The carbon footprint is a key climate impact indicator. It is used to measure the climate impact of governments, private companies, individuals and products alike. By measuring the carbon footprint, a company can see the volume of greenhouse gas emissions resulting from a product or activity. While the carbon footprint is a good indicator of the impact of a company’s greenhouse gas emissions, it does not capture the entire environmental impact.
Wood, the raw material for our products, is a renewable material that stores carbon throughout its life cycle. Forty-nine per cent of the mass of wood products is carbon, and they bind an average of one tonne of carbon dioxide for every cubic metre. Carbon is stored in wood products for their entire life cycle, which includes their use, re-use and recycling. Carbon is only released when the wood product is used for energy production or it decomposes.
Surprisingly, the key factor in our carbon footprint is our materials. Although the material itself, i.e. wood, has zero emissions in this calculation, adhesives make up a large share of the carbon footprint. Almost as significant were the emissions caused by logistics, that is the transportation of raw wood to manufacturing facilities, as well as transportation to customers. Many may not consider this to be Koskisen’s area of responsibility, but because our service includes delivery to customers, we feel that this needs to be included in our emission calculations. This gives our customers a truthful account of our emissions, which then facilitates their own CO2 emission calculations.
Plywood and chipboard products’ carbon footprint
We have drawn up EPDs and calculated CO2 emissions for the current product groups:
- Uncoated birch plywood KoskiStandard
- Birch plywood coated with phenol film
- Uncoated chipboard KoskiPan
- Melamine-coated chipboard KoskiMel
The calculations take into account the product stage that includes the raw materials, transport to the mill and manufacture. The CO2 emissions of products varied in the calculation between 291 and 438 kg CO2e/m3, so that the final carbon sink value for our wooden panels is:
- KoskiStandard -870 kg CO2-ekv/m3
- Phenol coated birch plywood -723kg CO2-ekv/m3
- KoskiPan -844 kg CO2-ekv/m3
- KoskiMel -740 kg CO2-ekv/m3
- Heat production from biomass was calculated as zero, otherwise based on heavy fuel oil (small share of total energy volume).
- The calculation takes into account the used raw materials, transports to mills, production and transport to the customer’s warehouse and disposal.
