SCA Group discharges are presented for the years 2005, 2006 and 2007.
It should be noted that in the last few years SCA has made a number of acquisitions. This year, four new conversion plants are presented for the first time in the RMS. Two paper mills have been removed since they no longer belong to the SCA Group.
Emission to air
Steam at the tissue mill in Valls, Spain.
Air emissions comprise emissions from all combustion units at SCA's production sites, including fossil fuel and biofuel emissions and emissions from purchased thermal energy. When energy (primarily thermal energy and/or electricity) is supplied to an external facility, air emissions are reduced in relation to the delivered energy in relation to the energy amount and the reduction is distributed among SCA's main products.
Three chemical compounds are measured and reported in relation to air emissions: NOX, SO2 and fossil CO2.
The stated CO2 figures may differ somewhat from those reported to local authorities under the EU Emissions Trading Scheme (ETS). This is because the countries participating in ETS use different limits and definitions for their calculations, while SCA calculates and presents RMS data according to a separate set of rules. A global company such as SCA, with operations on several continents, needs a single set of rules for calculating data to enable uniform reporting and monitoring of emission levels.

Air emissions from transport
A large portion of SCA's air emissions is generated by transports, rather than the company's production activities.

Emissions to water
SCA effluent water is divided into cooling water and process water. Cooling water has simply been heated and is not contaminated in any way. The total volume of discharged process water is 127 Mm³. This water is treated by methods similar to those employed for municipal sewage treatment facilities. The figures for 2007 refer to process water emissions.

Solid waste
The solid waste reported by SCA is waste that is sent to landfill, recycled waste and hazardious waste. Recycled waste refers to materials that can be used as raw materials in other industries, such as the cement, brick-making and construction industries. The main types of recycled waste are ash, sludge, organic waste and plastics. Hazardous waste is primarily waste oil as well as organic solvents, batteries and strip lights.
