The carbon footprints cover the production chain of our products, from the handling of raw materials to the finished product ready for delivery at the mill. We also present emissions from transport of products. However, these emissions vary due to the location of the customer, therefore we present the average emissions figures for transport, but on request we can supply the real figures for an individual customer.
Raw material
Carbon dioxide from harvesting and timber transport, as well as the emissions caused by the production of forest seedlings and silviculture. This also includes the collection and transportation of recovered paper, as well as emissions caused by other input items.
Production
Carbon dioxide from the production processes, including internal transportation in the plant. Most of the energy used in Laakirchen and Aylesford at efficient cogeneration plants connected to the mills. Östrand and Ortviken use a high share of biofuels.
Purchased energy
Our industries use electricity purchased from the grid, besides the electricity produced on site. This electricity from the grid comes from various sources. We estimate the emissions of carbon dioxide as the average for electricity production in the country in which manufacturing occurs. In Sweden, for example, hydro and nuclear power, which have extremely low carbon-dioxide emissions, account for most electricity production.
Transport
We are well in control of our carbon-dioxide emissions from transportation right up to the point when the product has been delivered to the customer. Here, we present the average emissions for delivery of one tonne of paper to a customer. We can, however, provide specific emissions data for deliveries to any particular customer on request..

Comments
The figure for transport to average customer is higher for LWC-paper from Ortviken compared to newsprint from the same mill, SC-paper from Laakirchen and newsprint from Aylesford Newsprint Ltd. This reflects that a greater share of LWC-paper was sold to customers overseas in 2008 and that Aylesford Newsprint is located near a concentration of customers in Southern England.
Aylesford and Laakirchen have higher carbon footprints than the Swedish mills. This reflects that most of the energy supply to these mills derive from nature gas fuelled combined heat and power plants. These CHP plants are very efficient energy sources, but the fuel is fossil, whereas the Swedish mills use a large share of biofuels. Sweden also has a low share of electricity from fossil fuels compared to for example UK.

The increase in carbon dioxide in the atmosphere primarily derives from the use of fossil fuels such as coal or oil. By using biofuel instead of fossil fuel a net emission of carbon dioxide is avoided.
SCA has an extensive biofuel operation. Logging waste and residue products such as sawdust, is used for energy production in heating plants or in households. Our mills also use extensive amounts of biofuels, but this is reflected through the low emissions of fossil carbon dioxide from the mills.
However, the sales of biofuels to external customers should be taken into account. SCA delivers 2.0 TWh of biofuels to external customers which means that emissions of 900 000 tonnes of fossil carbon dioxide has been avoided.
SCA is in the process of building 450 windmills on its forest land. The production of these windmills, when they are operative around 2015, will be 2.4 TWh of green electricity per annum. Through this emissions of more than one million tonnes of carbon dioxide from electricity production from fossil fuels man be avoided.
All our mills also have energyeffective CHPs producing both heat and electricity. At Östrand pulp mill we produce nearly 0,5 TWh of green electricity which contributes to avoided emissions from other sources of electricity production. The mills also deliver waste heat to the nearby communities, which reduces other sources for heat production to households.
SCA produces 1.8 million cubic metres of solid wood products. Wood has a much smaller carbon footprint than alternative materials such as aluminium, steel, plastic and concrete. It is difficult to set up general calculation models for measuring the amount of carbon dioxide substituted through the choice of wood before less climate friendly materials, but the amount is substantial. |
