Carbon footprint of Candy Cubicle by Sabine Marcelis
Sabine Marcelis notes that the Candy Cubicle celebrates wood in its natural state, a fact which contributes to the design being better than carbon neutral with a footprint of -(minus)80 kg CO2 eq. Total carbon emissions during all stages of material extraction, processing and transport, and for manufacturing at Benchmark are 105 kg CO2 eq. These emissions are offset by 18 kg CO2 eq. due to burning of wood offcuts at Benchmark (which substituted for fossil fuel) and 167 kg CO2 eq. of carbon stored in the wood. This is sufficient to offset a 630 km drive in a typical family car or 3.4 days of carbon emissions by the average EU citizen.
Sabine Marcelis also observes that the design approaches the wood material in an unexpected way and this is reflected in the carbon footprint. Unlike the other designs, the Cubicle is fabricated largely in birch plywood with maple used to veneer the visible surfaces. The inner surfaces are coated with a yellow high gloss varnish while the wheels combine cast resins with metal axles. This means that a relatively large share of emissions is associated with supply of wood products other than U.S. hardwood (33%) and with glues, fittings and finishes (46%).
