Wood has a largely favorable environmental effect. A study of the National Research Programme “Resource Wood” recommends using wood more widely as a source of energy and as a building material.
The study examined the overall environmental impact of wood in Switzerland, analyzing the value chain from cutting trees to recycling wood or burning it, including the manufacture of semi-finished products such as paper, boards and pellets for heating purposes. Wood manufacturing is a high profile industry in Switzerland, home to suppliers familiar in the U.S. such as IGP power coating, Michael Weinig machinery, Jowat adhesives, Swiss Chrono laminate panel, and Lamello.
The study indicates that the sustainable use of wood can contribute to meeting our needs in terms of energy and raw materials with a smaller footprint than other resources.
The study estimates that the use of wood in Switzerland leads to a reduction in CO2 emissions of between 2.0 and 3.1 million tons per year – in comparison, Switzerland emitted a total of 52.6 million tons in 2013. Replacing gas or oil with wood accounts for two thirds of the estimated reduction. The last third is linked to construction and furniture production where wood replaces materials with a high carbon footprint such as cement, steel, aluminum and plastics.
Conducted in the context of the National Research Programme “Resource Wood” (NRP 66), the study based its analysis on the one hand on comprehensive statistics of material flows (origin, use and disposal of wood) that were compiled by the federal offices in particular. On the other hand, it referred to several databases evaluating the life cycle of products. “We considered different environmental impacts, in particular in relation to climate change, energy consumption, air pollution and loss of biodiversity”, explains Florian Suter, first author of the study and doctoral student at the Chair of Ecological Systems Design at ETH Zurich.

The U.S. Department of Agriculture’s Forest Service Chief Tom Tidwell today announced over $8.5 million to expand and accelerate technologies and strategies that promote the use of wood in commercial construction, heat and power generation, and other wood product innovations that also benefit forest health. Federal funds will leverage more than $18 million in investments from 42 business, university, nonprofit and Tribal partners in 19 states, for a total investment of $27 million.
“We are looking for opportunities to reduce forest restoration costs and create more jobs through strong forest products markets,” said Chief Tidwell. “This funding supports improving forest health on the National Forest System lands and other forested lands and promotes the economic and environmental well being of rural communities.”
The awarded funds will stimulate the use of hazardous fuels from National Forest System lands and other forested lands to promote forest health while simultaneously generating rural jobs. This year, 77 proposals were received for the Forest Service’s Wood Innovations grant program, highlighting the expanding interest and use of wood as a renewable energy source and as an innovative building material.
Healthy markets for forest products help the nation’s forests mitigate some of the impacts of climate change. Research has demonstrated that wood products from responsibly managed forests outperform other building materials in measures of greenhouse gas intensity, air and water pollution and other environmental impacts. Responsibly-sourced forest products also provide income for private landowners that keep their land forested and supports needed investments in forest management to provide clean water, wildlife habitat, and other resources millions of Americans depend upon.
Today’s announcement supports USDA’s Building Blocks for Climate Smart Agriculture and Forestry-a comprehensive effort to provide America’s farmers, ranchers and forest landowners with the tools and resources they need to combat climate change. Through this work, USDA expects to reduce net emissions and enhance carbon sequestration in soils and forests by over 120 million metric tons of CO2 equivalent per year by 2025-the equivalent of taking 25 million cars off the road or offsetting the emissions produced by powering nearly 11 million homes each year.

Last month we saw cross-laminated timbers installed at the Albina Yard project in Portland. It was the first use of U.S.-produced CLT in a building-wide structural system.
The first level of CLT (4,000 square feet) on Albina Yard went up in fewer than four hours. Last week, the second level was installed by a crew of seven in under two hours. Pretty remarkable, considering the contractor says it would have taken at least twice as many people two days or more to frame the same amount of floor space using traditional methods. Albina Yard is a four-story, 16,000-square-foot creative office project in north Portland. Besides its snazzy design by LEVER Architecture, the project is most notable for being tangible evidence that the U.S. CLT industry is officially off the ground.
There’s been a lot of buzz around CLT and mass timber in general over the past several months in Oregon and around the country — and rightly so. Besides drastically improved speed of construction (and the savings that go with that), mass timber offers significant environmental benefits. This includes tremendous carbon-storing capacity. Half the dry weight of wood is carbon. It got there when the trees were growing and absorbing carbon dioxide from the atmosphere. That carbon remains locked up for as long as the wood remains in use (a nine-story wood structure in China is now 959 years old—nearly a millennium). The new trees planted to replace those that were harvested start the carbon cycle all over again.
According to a quick, back-of-the-napkin calculation, Albina Yard, which is small by commercial construction standards, stores about 80.5 metric tons of carbon. That’s equivalent to offsetting 295 metric tons of CO2 emissions.
A larger Portland mass timber building, Clay Creative (60,000 square feet), stores more than 1 million pounds of carbon. Its total of 457.5 metric tons offsets 1,678 metric tons of CO2 emissions. “An additional 3,574 metric tons of CO2 emissions were avoided by using wood rather than concrete and steel,” says Dr. Jim Bowyer, an expert on the subject at Dovetail Partners, Inc.

Jackson Morrill, president of Composite Panel Association, updated the executive committee’s recommendations on “policy positions” with regard to energy/biomass issues that impact wood fiber supply during the September Fall Meeting in Banff, Alberta.
CPA opposes government policies that distort the market for woody biomass raw material, Morrill noted, adding that market forces should determine all uses of wood and wood residuals for renewable energy; policies that have the direct effect of diverting biomass supply to subsidized energy should be avoided; and governments that choose to initiate policies intended to increase demand for biomass energy production should couple them with policies that increase the available long-term supply of wood to meet future demand of composite wood panels as well as new and growing markets for energy and other uses.
Morrill said CPA will stay silent on the carbon neutrality of wood-to-energy, noting however that forest derived biomass should be treated as carbon neutral where there is a sustainable growing forest; within carbon accounting frameworks, the composite panel industry’s use of wood residuals to make long-lived products should be treated as a higher value use than energy recovery; the composite panel industry’s use of wood residuals is an important alternate use that should be considered when determining the scope of “qualified biomass” under the U.S. EPA Clean Power Plan.
Morrill said CPA will advocate that composite wood products be recognized for their carbon sequestration benefits; that public policies should recognize that sustainably managed forests and forest products sequester and store carbon and reduce CO2; the use of biomass in creating long-lived products that serve as carbon sinks should be formally recognized in any carbon calculations that might be referenced in a future carbon economy.
