trends and future of sustainable development - TransEco

According to MuSIASEM model findings the following conclusions can be made: For every tonne of roundwood removal, less energy (except for the peak in 2001) is being used,hence referring to the conclusion that the process is becoming efficient (less inputs needed formore outputs produced) over time. Over time, more energy is going into each hour of work in forestry ultimately, leading to theconclusion that more and more roundwood is being removed per hectare and per hour of workover time. The energy used reflects the level of technical capital (machinery) employed in theactivity. Moreover, each tonne of roundwood is worth increasingly more over the years, probably due toincreasing prices in markets of the type of wood extracted in Finland.Within the scope of this study, Forest Industries have been regarded as the processes that processesthe raw material after the first stage of removal of the roundwood. The pulp and paper industry and thewood and wood products industry will be focused upon, while comparing it to the forestry sector attimes. In Finland, in general, it has been regarded that the industrial production has been both verymaterial and energy intensive (Braczyk et al, 1998).The ASA model uses for the decomposition techniques to produce information about factorscontributing to environmental burden and thus it explains reasons to different development trends.Since it is very hard to find suitable aggregate measures that describe all environmental hazards, thetotal carbon dioxide emissions (CO2) have been used as a proxy of environmental burden. In this casestudy the variables used in ASA model testing are: carbon dioxide (CO2) production volumes (PRO) employment (EMP) value added (VA) working hours (WH) final energy consumption (FEC)For testing in this case study the following equation (1) has been selected :CO2 FEC VA WH(1) CO2 = ------- x ------- x ----- x ------- x EMPFEC VA WH EMPFor this case study data about Finnish forest sector from 1980 to 2007 has been collected. This datahas been inputed to ASA software. The ASA summary table produces results of decomposition analysisin numerical and graphical form. The results are presented as graph in figure 8.91
