Are produces wooden building elements from sustainably managed local forests. The CO2 sequestered by the tree is stored for 50 to 100 years or more, creating a CO2 removal beyond the peak of global emissions. Their process is highly efficient, ensuring the removal of 532 kg CO2 per m3 of timber product.
Are has four production sites in Norway, each serving the local building market. They produce roof trusses, joists and other pre-cut wall elements using high-tech computer control cutting processes that minimise waste. The large share of renewable energy in Norway also contributes to low process emissions. All products are made-to-measure so that there is no loss of materials on site.
Each cubic meter (m3) of glulam beam stores 532 kg of CO2 that the timber absorbed from the atmosphere during its growth period. Are has accurately calculated the average net carbon content of each timber building element that they produce. All emissions from the harvesting of the timber, transport to the production facility, through to the production and packaging of the products were accounted for in the life cycle assessment (LCA) that Accend performed in accordance with ISO 14067 standards. DNV GL audited the facility, LCA and documentation for the issuance of Puro CORCs in December 2020.
The Puro Earth methodology describes CO2 removals, or drawdown of emissions, not emissions reductions or avoidance. The 532 kg/m3 of CO2e is a removal, NOT an avoided emission. Avoided emissions from the use of their products are primarily created by substituting concrete and steel in buildings. For comparison, 1 m3 of timber product from Are removes 532 Kg/m3, whereas a comparable re-inforced concrete beam has a footprint in excess of 300kg/m3. Such avoided emissions avoidance are additional to the CO2 that gets removed by Are's products.
The income from the sale of CORCs allows Are to be more competitive and win more tenders, further increasing the share of timber in buildings in relation to concrete or other less sustainable products.
