The carbon (C) reservoir of wood products in Finnish construction and civil engineering was estimated by three inventories including the years 1980, 1990 and 1995. The inventory method is mainly based on the statistics of Finnish building stock. The use of different construction materials in different parts of buildings is estimated for each building type. Information collected through building...
