Therefore, at the country level, despite having a large share of forests protected, the release of atmospheric CO2 from the Canadian forests due mainly to decay of organic matter and harvesting exceeds the removal due to forest growth (Environment Canada 2012). If this trend continues, the Canadian forests will act as a carbon source in this decade. Even though it is rather a theoretic estimation, the value gives a good approximation of what the Nordic forest carbon sink worth monetarily and the theoretical size of a possible Nordic sink market, With a constant price of €5/tC02 and 3% annual market interest rate, the present value is estimated to be just under 900 million Euros in the beginning of 1990ies.
