Across North America, trees stand ready to help us solve the climate crisis. …This opportunity arises from cross-laminated timber… it enables architects and engineers to design tall, fire-safe and beautiful wood buildings. …The energy embodied in the materials for new buildings around the world — mostly steel and concrete — accounts for 11 percent of global carbon emissions. …Wood, in contrast, is forged from sunlight. A study by scientists from Yale University and the University of Washington showed that expanding wood construction while limiting global harvesting to no more than the annual growth could produce a combination of emissions reduction and carbon sequestration equivalent to eliminating construction emissions altogether. …Additional benefits come from the fact that these new wood technologies make it affordable to construct mid-rise housing of six to 12 stories. …To stabilize climate and support the wood building revolution, we need to stop the conversion of forests to other uses.
