Forest Management & Certification

APA wood products are sourced from sustainably managed resources and consume far less energy compared to metal and petroleum based products, leaving future generations a significantly smaller carbon footprint.  This renewable, recyclable and biodegradable resource is easily manufactured into a range of products that reduce waste by decreasing disposal costs and product damage.


Today’s sustainably managed North American forests comply with one or more of the five leading certification agencies responsible for verifying proper forestry practices. These practices include following applicable laws, protecting wildlife, providing habitat buffers and ensuring waste reduction and reuse.   Forest management certifications of select APA engineered wood manufacturing members.

Energy efficiency of manufactured wood

Processing wood into usable products is highly energy efficient. Wood product sourcing and production consume far less energy compared to metal and petroleum-based products, leaving a significantly smaller carbon footprint for future generations.

Compared with wood, it takes five times more energy to produce the same amount of cement, 14 times more for glass, 24 times more for steel and 40 times more for aluminum.

While wood products account for 47 percent of all industrial raw materials manufactured in the United States, they consume only 4 percent of the total energy needed to manufacture all industrial raw materials.

US plants more trees than it harvests: recent USDA Forest Service data confirms that US forestland is roughly the same today as it was 100 years ago. The last two decades have seen an impressive investment in the renewal and expansion of North America managed forests with around 27 percent more trees now being planted than harvested each year. In total, North American forest plant two billion trees annually. In addition, millions of trees seed naturally.

Wood is carbon neutral:  wood is the world’s only naturally renewable building material. Derived entirely from solar energy, wood fibre resource is a keystone in reducing global warming. Forests mitigate climate change by absorbing carbon from the atmosphere and storing it in trees, soil and biomass.

Wood’s net carbon emissions are below zero. The CO2 absorbed by growing forests and stored in trees and wood products offsets the energy required to harvest, process, transport and maintain those products over time. And quality, durable products made from wood continue to store the carbon for generations to come.

Young, growing trees absorb more carbon dioxide than older mature trees: for every ton of wood grown, a young forest produces 1.07 tons of oxygen and absorbs 1.47 tons of carbon dioxide. But as the forest matures, growth slows, and the absorption rate drops off. Harvesting a mature forest sequesters the carbon in the wood, so it is not released into the atmosphere. A 2,400-square-foot wood-frame house, for example, has 28.5 tons of carbon dioxide sequestered, roughly equivalent to seven years’ worth of emissions from a small, light-duty car.
