One building stands out in the old logging town of Prince George, Canada. Encased in a sleek glass facade, the structure towers above most of its neighbors, beckoning from afar with the warm amber glow of Douglas fir. Constructed almost entirely from timber in 2014, the 8-story, 30-meter building is among the tallest modern wooden structures in the world. But it is more than an architectural marvel. As the home of the Wood Innovation and Design Centre at the University of Northern British Columbia (UNBC), it is also an incubator for wooden buildings of the future — and a herald for a movement that could help to tackle global warming.
The building is less like a log cabin and more like a layered cake, constructed from wooden planks glued and pressed together, precision cut by factory lasers and then assembled on site. All told, the university avoided the release of more than 400 tons of carbon dioxide by eschewing energy-intensive concrete and steel, and the building locks up a further 1,100 tons of CO2 that was harvested from the atmosphere by British Columbian trees. In total, that’s enough to offset the emissions from 160 households for a year.
Wooden construction has ancient roots, but only in the past two decades have scientists, engineers and architects begun to recognize its potential to stave off global warming. By substituting concrete and steel with wood from sustainably managed forests, the building industry could curb up to 31% of global carbon emissions, according to research by Chad Oliver, a forest ecologist at Yale University in New Haven, Connecticut. In time, such a shift could help humanity to pull CO2 out of the atmosphere, potentially reversing the course of climate change.
“It’s the plywood miracle,” says Christopher Schwalm, an ecologist at Woods Hole Research Center in Falmouth, Massachusetts. “This is something that could have a significant impact on the riddle that is global environmental change.”

The American Wood Council has been awarded a $250,000 grant from the U.S. Department of Agriculture (USDA) to conduct research on the fire performance of mass timber buildings. AWC will partner with the National Fire Protection Association’s (NFPA) Fire Protection Research Foundation and the Property Insurance Research Group.
The AWC proposal is intended to advance the construction of taller wood buildings in the United States by demonstrating the fire performance of newer mass timber products. Over the last several years, tall wood buildings have been completed around the world using this new technology – including a 9-story building in London, 10-story in Prince George, Canada, and 14-story building now under construction in Bergen, Norway. These buildings have consistently demonstrated the successful application of mass timber technologies.
“Findings from this project will inform the building community and the insurance industry, providing an increased level of confidence in both the adequacy of this new construction type and when setting fire insurance premiums. This is a new method of construction to insurers, and in order to provide reasonable insurance coverage, they need to understand the performance of the material,” said AWC Vice President of Codes & Regulations Kenneth Bland. Increased use of wood in building construction also holds great promise for improved environmental impacts.
“Innovative mass timber wood products encourage sustainable forestry and capture large amounts of carbon, thereby reducing greenhouse emissions through both sequestration and the substitution of wood for more carbon-intensive products. The construction of tall wood buildings would put America at the forefront of an emerging global opportunity,” said AWC President & CEO Robert Glowinski.
When announcing the USDA 2015 Wood Innovations grant recipients, Agriculture Secretary Tom Vilsack said, “Working with our partners, the Forest Service is promoting deployment of new technologies, designed to support new market opportunities for wood energy and innovative wood building materials.”
