The recent United Nations global climate summit in Glasgow, Scotland, brought the world’s leaders together again to try to reach agreement on further commitments to reducing greenhouse gas emissions. High on the agenda was preserving the health of the world’s forests – a critical natural resource for absorbing these emissions.
With this heightened international attention on preventing deforestation, primarily in the developing world, now is a good time to remind ourselves that the North American forests that supply the wood fiber for our paper and packaging products are among the most sustainably managed in the world.
They are so well-managed, in fact, that our forests continue to be a net absorber of carbon. In the United States, sustainable forest management practices, the regeneration of forest area and modern harvesting practices resulted in a net sequestration of carbon every year from 1990 to 2019, according to the U.S. Environmental Protection Agency. The U.S. Forest Service (USFS) reports that U.S. forests annually capture and store 14% of economy-wide carbon dioxide emissions. Natural Resources Canada reports that forestlands capture and store around 19% of all carbon dioxide equivalents emitted in the country.
The production of wood and paper products is a powerful economic engine and driving force in keeping North American lands forested. By providing a dependable market for responsibly grown fiber, the paper industry encourages landowners to manage their forestland instead of selling it for development or other non-forest uses. More than half (58%) of the forestland in the U.S. is privately owned and managed, mostly by millions of small landowners, and they are under no obligation to keep their lands forested. Without the economic incentive provided by the forest products industry, untold millions of acres of forestland would likely have been lost permanently to commercial land development – converted to building projects, strip malls or parking lots.
For proof, look no further than countries where there is little economic incentive to keep lands forested. According to the UN Food and Agriculture Organization’s (FAO) Global Forest Resources Assessment, those areas of the world that consume the least amount of wood have the greatest problem with the kind of deforestation that the Glasgow conferees were trying to address.
Compare that with North America’s forest products industry. While they were producing the wood and paper products that enrich the lives of consumers, net forest area in the U.S. grew by some 18 million acres between 1990 and 2020, according to the UN FAO, and Canada’s forest area of 857 million acres has been stable over the same period. By law, every acre of Canadian forest that is commercially harvested must be regenerated.
In the U.S., the net average annual increase in growing stock on timberland is about 25 billion cubic feet, according to the USFS, and forests in the U.S. annually grow nearly twice as much wood as is harvested. USFS also reports that tree harvesting in the U.S. occurs on less than 2% of forestland per year in contrast to the nearly 3% disturbed annually by natural events like insects, disease, and fire, and most of this harvested wood is used for non-paper purposes. Harvesting in Canada occurs on only 0.2% of forestlands, while 4.7% is disturbed by insects and 0.5% is disturbed by fire, this according to Natural Resources Canada.
The Glasgow summit also kicked off a discussion of the inherent advantages of bio-based materials – like paper and paper-based packaging– in reducing greenhouse gas emissions and their potential role in a more broad-based, circular bio-economy. The FAO released a report demonstrating how renewable wood-based products can help combat climate change and achieve the UN Sustainable Development Goals.
According to Dr. E. Ashley Steel, Forest Statistics Expert at the UN FAO:
“There is strong evidence at the product level that wood products are associated with lower GHG emissions over their entire life cycle compared to products made from GHG-intensive and non-renewable materials. Wood and wood-based products are generally associated with lower fossil and process-based emissions when compared to non-wood products.”
The document left open for later study the extent to which paper and paper-based packaging may serve as substitutes for non-wood products in the search for those that contribute to the net reduction of greenhouse gases, but there’s little doubt that any product sourced from materials that are grown and regrown are better for combating climate change than the non-paper alternatives.
