Tiivistelmä
The thesis was commissioned by Wood from Finland Association, and its main subject was to determine, calculate, and study the carbon footprint of Finnish exported wood products in the top 25 countries. The top 25 countries were discovered in autumn 2020 for another thesis made by students from LAB University of Applied Sciences and most of the information and data is based on that.
The first part of the two-part thesis dealt with a theory that was used to interpret the results of the second part. The second part contained data calculations compiled using Microsoft Excel. For each country, only the most exported wood product, either redwood(pine) or whitewood(spruce) was considered in calculations. All baseline data were reported only for CO2 emissions, so the other GHG emissions were not taken into account in calculations.
The density of Finnish wood in the calculations was 0,55 t/m3 for pine and 0,47 t/m3 for spruce. Possible losses in production of wooden products are 5 to 15 % per m³ and calculations are made by using the maximum figure. Carbon dioxide emissions were calculated by multiplying distance (kilometres or nautical miles, depending on the type of transport used) CO2 kilograms per ton kilometres or nautical miles, and the total volume exported with each other.
The results of the study and calculations showed that exports to China, Japan, and Egypt caused most of the CO2 emissions with the range of 170 000-280 000 tonnes, while exports to the Netherlands, UK and Estonia caused the lowest emissions with the range of 6000-31 000 tonnes. The greatest CO2 stores were in Egypt, China, and Japan, with the range of 250 000-350 000 tonnes, and the lowest in the Netherlands, Estonia, and France, with the range of 34 000-84 000 tonnes. The longest storage time for CO2 was in Glulam products and the shortest one in packaging products.
