You are calculating the carbon footprint of using Material W as wall insulation. You plan to use a functional unit of 1 m of wall insulation designed to reach a specific thermal transmittance. Material W has a carbon footprint of 8.5 kg COeq/kg for its production and transportation, and a density of 32 kg/m. Its thickness must be 0.15 m when applied inside a wall in order to reach the desired thermal transmittance. Given just this information (and assuming that installation and landfilling are negligible impacts for this system), what is the carbon footprint of Material W insulation, in units of kg COeq/m?
