Greenhouse impact of the use of peatland for energy -scenarios considering peatland utilisation and after-treatment

摘要

The greenhouse impact of the use of peatland for energy has been assessed using life cycle assessment.The utilisation of peatland has been taking into account comprehensively:first the area is used for fuel peat production and then for biomass production (afforestation or cultivation of reed canary grass).Utilisation of forestry-drained peatland in Finland for energy production causes a somewhat lower climate impact than using coal even within a 100 year time horizon,if the utilisation of renewable biomass produced in the after-treatment of the peatland is taken into account.If cultivated peatland is used for energy production,the greenhouse impact is lower than the use of forestry-drained peatland or coal for energy.
