Pulpwood and timber are first transported to a road and then to pulpmills and sawmills. In order to reduce costs and environmental impact, forestry companies trade wood with one another. Transport companies improve efficiency by planning their shipments to ensure they move cargo in both directions. Raw materials arrive at the Korsnäs mill by car, ship and rail, with each mode of transport accounting for about a third of the total volume.

 
From the standpoint of natural materials cycles, the transports are the weak link. We have made great strides through greater efficiency, better engines and more environment-friendly fuels. But it would be a big step forward for the environment if fuel producers could provide an economically competitive fuel on a large scale that reduced emissions affecting the climate and the environment. When the forest grows larger, it can take up a certain percentage of carbon dioxide emissions from transports. But as long as fossil fuels are in use, the buffering capacity of the forest will not be enough.
