Stora Enso intends to make optimal use of its considerable potential to contribute towards mitigating climate change. The best ways to combat climate change are by further increasing the use of wood-based bio-fuels, and by making continuous improvements in energy-efficiency. These aims are given high priority in all investment decisions.
 Bark, sawdust, black liquor and logging residuals are all important wood-based energy sources. During 2002 Stora Enso found new ways to use these CO2-neutral bio-fuels.
Reducing carbon dioxide emissions
Emissions of carbon dioxide from the combustion of fossil fuels have been reduced by some 4 000 tonnes, in spite of slightly increased production. Notable contributions were made by Imatra Mill, where bio-fuels were used instead of peat, and by Port Hawkesbury Mill, where coal was replaced by gas.
Commitment to environmental management systems provides
a sound basis for consistent and transparent monitoring
of environmental impacts. This year's environmental
report is even more detailed than previous reports,
as it also includes mill specific CO2 emissions
(see
table). Emission figures are given for both renewable
and non-renewable energy sources, even though renewable
fuels are considered to be CO2-neutral
in the Kyoto Protocol. Carbon dioxide is by far the
most important greenhouse gas where Stora Enso's operations
are concerned, so it is the only greenhouse gas monitored
at Group level.
Energy audits in North America
Stora Enso North America completed its first round of energy-efficiency audits during 2002, following similar procedures to those applied earlier in European units. It is vital that continuous improvements are sought in everyday operations. This can be seen from the case of Stevens Point Mill, where electricity consumption per tonne of product has been reduced by 3% through installing new energy efficient lighting fixtures, and by shutting down non-essential equipment.
