Forestry experts contend that the rapid growth in popularity of the mass timber industry must be married with sustainable forestry initiatives, such as certification standards, to ensure that the harvest, manufacturing and transportation processes are environmentally friendly, transparent and included in more accurate cost-benefit analyses. The small amount of embodied energy (carbon) in one ton of concrete, when multiplied by the huge amount of concrete used, results in concrete being the material that contains the greatest amount of carbon in the world. As an innovation in the industry, mass timber construction emits significantly less carbon than traditional concrete and metal structures, while modular construction ensures usability across many building types.
