This paper estimates the total amount of CFCs and HCFCs involved in insulation foams within all existing buildings in Japan by using two kinds of database. The database of remained amount of fluorocarbons that was obtained in the previous paper (Part 1) is revised by revising initial concentration data of CFCs and HCFCs in hard polyurethane and extruded polystyrene insulation foams. The other one, that is a database of total stock of insulation foams, is obtained by shipment statistics of insulation foams, loss ratio on construction site and demolishing ratio for elapsed years. The transitions of remained amount of fluorocarbons from 2002 to 2022 (every 5 years) are also estimated and the Mass-Balances of CFCs and HCFCs in all insulation foams are obtained.
