Abstract
In Finland in 1993 the greenhouse gas emissions caused by machinery used in silvicultural and forest improvement work, wood harvesting, and timber transportation were 424.2 Gg carbon dioxide (CO 2 (Gg = gigagram = 10 9 g), 10.6 Mg nitrous oxide (Mg = megagram = 10 6 g), 3.5 Gg carbon monoxide, 31.5 Mg methane, 5.6 Gg nitrogen oxide, and 0.7 Gg non-methane volatile organic compounds. When emissions were converted into equal units as global warming potential in terms of CO 2 , the warming effects on a 20-year time frame equalled 1310 Gg as CO 2 and on a 100-year time frame 669 Gg as CO 2 . The proportion of silvicultural and forest improvement work of the total emission was 8 per cent, cutting of timber 13 per cent, haulage 18 per cent, long-distance transportation 57 per cent, and transportation of machinery 4 per cent. The emissions caused by the use of primary energy in forestry seem to be small compared with the amount of carbon in harvested timber, which was 30 300 Gg in terms of CO 2 .Keywords
