Abstract

This paper presents an assessment of the life cycle operation phase of forest cableways Larix 550 and Larix 3T with respect to energy requirements and environmental pollution caused by emissions. Energy audit quantifies energy use based on the consumption of fuels and lubricants. Energy balance includes both the energy content and the energy needed for the production of fuels and lubricants. Fuel consumption measured for one year ranged from 1.2 – 1.4 l/m^3. Based on the consumption of fuels and lubricants the paper quantifies the amount of emissions in two scenarios (minimum consumption and maximum consumption) with a special focus on GHG emissions. Calculations are made of emissions for diesel fuel and for the alternatively applicable rape-seed methyl ester (RME), and a calculation is also made of emissions originating from fossil sources. By using RME as a fuel, the amount of CO2 emissions from fossil sources discharged into the environment can be reduced by 3.4 kg per a cubic meter over the bark of timber extracted by cableway.
