Sustainable Development Conference May 26, 20093
Important energy achievements in the Swedish pulp and paper industry during the last decades
• Oil consumption reduced by almost 80% since beginning of the 1970s while production has doubled
• Use of biomass for energy purposes almost doubled
• Energy efficiency increased
Main reasons for changes:- Increasing oil prize- Environmental restrictions

Important environmental achievements in the Swedish pulp and paper industry during the last decades
• Emissions of sulphur compounds has declined by over 95% since the beginning of the 1980s
•Emissions of dissolved organic substances (COD) have been reduced by over 85%
• Emissions of chlorinated organic compounds (AOX) have decreased by over 95%
