A recent study from the International Institute for Sustainable Development (IISD) has found that many life cycle assessments (LCAs) that show wood construction lowers carbon emissions often overlook several important factors. Most notably, the Winnipeg-based think tank said typical LCAs do not track or account for “biogenic” carbon — a category that includes carbon losses related to soil disturbances, imperfect reforestation efforts and the conversion of old-growth primary forests to less productive secondary forests. These sources can account for up to 70 per cent of total lifecycle emissions and “challenge the prevailing assumption wood construction materials are less carbon intensive than steel or concrete and should be favoured.” To read more, click here.
