The paper manufacturer also said it had decreased its sulphur dioxide output by 30% in 2008 compared with 2007 and reduced the amount of landfill waste by 12%.
UPM is also looking at its "water footprint", and will continue to lower its usage of water in its operations.
The quality of recovered fibre is also an issue as the trend for mixed papers or co-mingled collections increases.
Since 1990, UPM has invested €1bn in its new mill site biomass-fired power plants and recovery boilers. These long-term investments have reduced fossil CO2 emissions by 40% per tonne of paper.
The company announced in September last year that the building of its £59m combined heat and power plant (CHP) at its Caledonian mill was going according to plan.
Construction of the CHP at the 350-staff mill in Ayrshire, Scotland, will replace the existing coal-fired boiler. It is expected to be in commercial operation on 20 May 2009.
