1) Most of the stated sum comprises installation of new equipment for sludge management at Hallsta Paper Mill. Costs for treatment equipment for weak gases at Iggesund Mill form another significant part of the stated amount.
2) Most of the stated sum comprises environmentally related parts of the new biofuel boiler at the mill in Workington.
Environmentally related costs for the recovery boiler at Iggesund Mill also represent a major share.
3) The stated amount includes costs for waste management, energy tax charged in Sweden on the use of fossil fuels, sulphur tax, nitrogen oxide tax and inspection charges.
4) This includes costs of environmental personnel, operation of treatment equipment, waste management, management systems, environmental training, applications for permits, environmental consultants and the costs of measures in connection with discontinued operations.
5) The environmental costs of forestry is calculated as the value of the wood that is not harvested for environmental reasons. Holmen sets aside 10 per cent of its productive forest acreage for environmental reasons and thus refrains from harvesting around 10 per cent of the potential volume. The annual loss of income is estimated at around SEK
93 million.

At Iggesund Mill large amounts of thermal energy are produced by burning wood-containing liquors.
Significant quantities are also generated by burning bark. At Hallsta and Braviken Paper Mills surplus heat is recovered from the TMP production process. Natural gas is used at the mills in Workington and Madrid.
Comments on the table on page 92
1) At Group level, wood consumption is computed net, taking into account internal deliveries of chips from the sawmills to the nearby mills.
2) Process wastewater 57 million m 3 . Cooling and seal water 17 million m 3 . New statistic from 2011.
3) 100 per cent active substance.
4) Figure adjusted.
5) Thermal energy is produced from the electricity used in the production of thermo-mechanical pulp at Braviken Paper Mill and Hallsta Paper Mill; this is recovered and used in production.
6) The reporting includes data for gas consumption and associated emissions linked to Holmen’s share of electricity production at the half-owned cogeneration (COGEN) plant at Holmen Paper Madrid. The data also includes natural gas and oil used at the mills.
7) In 2012, emissions of fossil carbon dioxide from production of purchased thermal and electric energy totalled approximately 123 000 tonnes.
8) The direct emissions of fossil carbon dioxide and nitrogen oxides from Holmen mills increased in 2012 compared to 2011. The reason for this is that, in the middle of 2012, the mill in Workington took over the plant from which energy was previously purchased. The energy produced is based on natural gas. This plant will be replaced by a biofuel boiler at the start of 2013. The new boiler will provide the mill’s total energy requirements in the form of thermal and electrical energy. Emissions of fossil carbon dioxide and nitrogen oxide from the mill will then more or less cease.
9) Hazardous waste is dealt with by authorised collection and recovery contractors. Certain fractions of the waste are recovered. Oil-containing waste from docking ships is dealt with at port facilities at three Holmen mills. In 2012 the amount of this waste was 1 205 tonnes.
10) Waste used, for example, as filling material, construction material or for the production of soil products.
11) For delivery to the chemical industry.
