Sustainable Forestry Initiative

The Sustainable Forestry Initiative (SFI) is a sustainability organization operating in the U.S. and Canada that works across four pillars: standards, conservation, community, and education. SFI was founded in 1994 by the American Forest & Paper Association (AF&PA).[1][2] SFI is the world's largest single forest certification standard by area.[3] SFI is headquartered in Ottawa and Washington, D.C.

In 2005, the Programme for the Endorsement of Forest Certification, which itself is the world's largest forest certification system, recognized the SFI standard.[4]

SFI standards

The SFI 2022 Forest Management Standard covers key values such as protection of biodiversity, species at risk and wildlife habitat; sustainable harvest levels; protection of water quality; and prompt regeneration.[5] SFI has certified more than 370 million acres (150 million hectares)[6] to its standard in the United States and Canada.

The SFI 2022 Fiber Sourcing Standard promotes responsible forestry practices based on 13 Principles, 11 Objectives, 29 Performance Measures and 59 Indicators that address the 90 percent of the world's forests that are not certified.[7] The SFI 2022 Fiber Sourcing Standard distinguishes SFI from all other forest certification programs in that it sets mandatory practice requirements for the responsible procurement of all fiber, even if it is sourced from non-certified land. These fiber sourcing requirements include measures to broaden the practice of biodiversity, use best management practices to protect water quality, and utilize the services of forest management and harvesting professionals. Because it governs how SFI-certified organizations procure fiber from non-certified land, supporters argue that the standard encourages the spread of responsible forestry practices.

The SFI 2022 Chain-of-Custody Standard is an accounting system that tracks forest fiber content (certified forest content, certified sourcing and recycled content) through production and manufacturing to the end product.[8]

All SFI certifications require independent, third-party audits[9] and are performed by internationally accredited certification bodies.[10]

The new set of SFI 2022 Standards and Rules, developed through an open review process, took effect on Jan. 1, 2022.[11] The SFI 2022 Standards and Rules include new requirements in a number of areas. The SFI Climate Smart Forestry Objective requires SFI-certified organizations to ensure forest management activities address climate change adaptation and mitigation measures. The SFI Fire Resilience and Awareness Objective requires SFI-certified organizations to limit susceptibility of forests to undesirable impacts of wildfire and to raise community awareness of fire benefits, risks, and minimization measures. The new Objective 8, Recognize and Respect Indigenous Peoples’ Rights, ensures respect for Indigenous Peoples’ rights and traditional knowledge, and are aligned with the principles of the United Nations Declaration on the Rights of Indigenous Peoples.

The SFI standards are revised and updated regularly to incorporate the latest scientific information and to ensure continual improvement. Draft SFI standards were publicly available throughout the revision process on the SFI website. Input was received during 10 public webinars. SFI gathered input from more than 2,300 stakeholders from the conservation community, Indigenous communities, the forest products sector, brand owners, private forest landowners and public forest managers, government agencies, trade associations, landowner associations, academia, and the public.[12]

Independent oversight was provided at each stage of the revision process by the SFI External Review Panel, a group of independent experts representing conservation, professional, academic and public organizations, operating at arm's length from SFI. The SFI External Review Panel reviewed every public comment submitted to ensure that all comments were considered, and to guarantee the Standard revision process was transparent, objective and credible. The responses to comments are posted on the SFI website.

SFI standards only apply to forestlands in the United States and Canada, and SFI-certified organizations must comply with all applicable laws. For sources outside of North America without effective laws, participants must avoid illegal or other controversial sources.[13] SFI supports activities by international experts to find ways to address the problem of illegal logging[14] and is a member of the international, multi-stakeholder Forest Legality Alliance.[15]

SFI sponsored a world record attempt for tree planting. During this attempt in May 2015, 29 teams came together to plant 202,935 trees in one hour across North America. The teams included youth, community groups and industry partners.[16]

SFI Board of Directors

The Board of Directors that governs SFI has three chambers are divided into economic, environmental and social sectors.[17]

The current board of directors includes prominent members of the Canadian forestry industry, including Don Kayne, the CEO of Canfor and James K. Irving, the owner of J. D. Irving, Limited. Notable environmental representatives on the board include Dr. Tracey Farrell, CEO of the International Union for Conservation of Nature and Andrew Parr, President of the American Bird Conservancy. Additional members of the board come from social action groups, Indigenous organizations, government, professional associations of foresters, and other non-profits.[18]

Research publications

SFI mandates innovative and impactful conservation research that builds knowledge and improves forest outcomes.[19] SFI-certified organizations must support forest research as a condition of their certification. SFI science and conservation staff contribute directly to research papers about SFI supported research. Since 1995, $1.9 billion has been invested in forest research through SFI and its network.[20]

PLOS Climate (June 2023) Climate-Smart Forestry: Promise and risks for forests, society, and climate ― This paper, co-authored by Lauren Cooper, SFI’s Chief Conservation Officer, discusses how climate change is presenting a global challenge to society and ecosystems. This is changing long-standing methods to determine the values of forests to include their role in climate mitigation and adaptation, alongside traditional forest products and services. Forests have become increasingly important in climate change dialogues, beyond international climate negotiations, because of their framing as a Natural Climate Solution (NCS) or Nature-Based Solution (NBS). In turn, the term “Climate-Smart Forestry” (CSF) has recently entered the vernacular in myriad disciplines and decision-making circles espousing the linkage between forests and climate. This new emphasis on climate change in forestry has a wide range of interpretations and applications. This paper finds that CSF remains loosely defined and inconsistently applied. [21]

International Journal of Forest Engineering (Dec. 2022) Access feature areas within clearcut harvests by region across the southeastern US ― This research focused on the soil disturbance, erosion, and stream sedimentation associated with forest harvesting roads, trails, and stream crossings. The research showed an increase in total harvest area was associated with a significant decrease in the percent area occupied by access features such as roads, trails, and stream crossings.This work was supported by SFI, the Virginia Tech Forest Operations and Business Research Cooperative, the Virginia Tech Department of Forest Resources and Environmental Conservation, the McIntire-Stennis Program of the National Institute of Food and Agriculture, US Department of Agriculture, and the National Council for Air and Stream Improvement.[22]

Forest Ecology and Management (Sep. 2022) Increased levels of forestry best management practices reduce sediment delivery from Piedmont and Upper Coastal Plain clearcut harvests and access features, southeastern states, USA ― “Best management practices and their international equivalents can be voluntary, mandated by state or federal law (Titus et al., 2021), or required by third party forest certification systems such as the Sustainable Forestry Initiative (SFI) or the Forest Stewardship Council (FSC) (Tumpach et al., 2018).” This research discusses the essential role of forest management in erosion control and water quality protection in the Piedmont and Upper Coastal Plain of the southeastern U.S. [23]

The Forestry Source (July 2022) At Issue is Deforestation “Right Here in River City” ― “In hopes of avoiding legal gridlock, federal and state agencies responsible for designing, financing, and conducting wildfire risk reduction thinning projects need to be thoroughly transparent and appropriately participatory with respect to parties of interest. These forestry agencies should consider the active involvement and third-party oversight of the two leading forest management certification programs active in the US: the Sustainable Forestry Initiative (SFI) and the Forest Stewardship Council (FSC).” This article, from the Society of American Foresters, highlights the role of forest certification in combatting deforestation due to climate change. [24]

Forest Science (March 2022) Estimated Erosion from Clearcut Timber Harvests in the Southeastern United States — Timber harvests with inadequate forestry best management practices (BMPs) can accelerate soil erosion, which has been associated with reductions in water quality and site productivity. Previous studies affirm positive water quality effects accrued by harvesting with BMPs. However, few studies document erosion rates and masses associated with harvest and access network features (e.g., decks, roads, skid trails, stream crossings) across different southeastern regions. This research evaluated 109 recent harvests across eleven southeastern states and three topographically different regions (Coastal Plain, Piedmont, and Mountains). This work highlights the importance of harvest planning and minimizing bare soil areas, especially in the steep and challenging terrain of the Mountain region. This research received financial support from the National Council for Air and Stream Improvement, SFI, the Department of Forest Resources and Environmental Conservation, Virginia Tech, the Virginia Tech Forest Operations and Business Research Cooperative, and the McIntire-Stennis Program of the National Institute of Food and Agriculture, US Department of Agriculture.[25]

Business Strategy and the Environment (May 2021) Using technology to improve the management of development impacts on biodiversity ― Co-authored by Leo Viana, SFI’s Vice President, Conservation Collaboration, the paper discusses how synergies between business and technology offer the opportunity for improved outcomes for biodiversity conservation via the use of existing and emerging technologies.[26]

Forests (Jan. 2021) Non-Native Earthworms Invade Forest Soils in Northern Maine, USA ― This work documents the presence of non-native earthworms that have the potential to abruptly change soil properties and deplete or redistribute soil carbon stocks. In Northern Maine, where the study took place, winters were previously thought to be too harsh for earthworm populations to survive. Thanks to this work, scientists and forest sector professionals are now aware of the presence of worms and can begin to consider ways to reduce their impact. This project was supported by an SFI Conservation Grant to the University of Maine.[27]

Forest, Range and Wildland Soils (July 2020) Influence of mechanized timber harvesting on soil compaction in northern hardwood forests ― The paper describes a project that evaluated and refined methods for minimizing soil compaction during harvesting operations. Soil compaction can have negative effects on a forest’s ability to regrow after harvesting, and this work helps inform best management practices to help minimize this issue and improve management of forests certified to the SFI Forest Management Standard. This project was supported by an SFI Conservation Grant to the University of Maine.[28]

Reviews and comparisons

Third-party reviews

The United Nations Economic Commission for Europe/Food and Agriculture Organization, in its 2009–2010 Forest products Annual Review, says: "Over the years, many of the issues that previously divided the (certification) systems have become much less distinct. The largest certification systems now generally have the same structural programmatic requirements."[35]

Dovetail Partners Inc., in its 2010 Forest Certification: A Status Report, states: "the previous differences between forest certification programs are much less distinct ... each program generally has the same structural programmatic requirements, although the required content and level of detail provided by each may vary considerably."[36]

SFI is considered less stringent by some people than the Forest Stewardship Council (FSC).[37][38] For example, SFI allows more tree farming and does not require conservation plans or consultation with local and indigenous stakeholders (except for public lands).[38]

SFI was less highly rated than FSC for example by Consumer Reports “Greener Choices”,[39] and Green America.[40] Others rate SFI/PEFC and FSC equally: TerraChoice (part of Underwriters Laboratories Global Network) in its 2010 Sins of Greenwashing report, like its 2009 one, counts the SFI/PEFC and FSC in its second-tier list of "legitimate" environmental standards and certifications.;[41] as does Environment Canada's EcoLogo.[42]

A National Association of State Foresters forest certification policy statement[43] passed by resolution in 2008 states: "While in different manners, the ATFS (American Tree Farm System), FSC (Forest Stewardship Council), and SFI systems include the fundamental elements of credibility and make positive contributions to forest sustainability. No certification program can credibly claim to be ‘best’, and no certification program that promotes itself as the only certification option can maintain credibility."

Green Building Council

On April 5, 2016, the U.S. Green Building Council issued a Leadership in Energy and Environmental Design (LEED) pilot alternative compliance path (ACP) designed to screen out illegal forest products from LEED buildings. While the ACP is being tested as a credit, it will ultimately become a prerequisite that applies to all LEED projects. As a pilot, the ACP does not become a permanent part of the LEED standard without an affirmative vote of the USGBC membership. The ACP pilot recognizes all certified sources – FSC, PEFC, SFI and ATFS and programs.[44] The ACP will apply to all LEED v4 rating systems including Homes v4[45] and to all LEED 2009[46] rating systems.

The ACP categorizes the various forest certification standards based on the ASTM D7612-10 (2015) standard, which is titled “Categorizing Wood and Wood-Based Products According to Their Fiber Sources.”[47] ASTM (American Society for Testing and Materials) International is a globally recognized leader in the development and delivery of voluntary consensus standards.

Other green building tools, including two American National Standards Institute (ANSI)-approved rating systems in the United States – ANSI-ICC 700–2008: National Green Building Standard[48] and ANSI/GBI 01-2010: Green Building Assessment Protocol for Commercial Buildings (formerly Green Globes U.S.[49]) – Green Globes and Built Green Canada recognize wood products certified by credible third-party certification programs like SFI.

Conservation organizations

SFI is supported by conservation groups such as the American Bird Conservancy, Ducks Unlimited Canada, Arbor Day Foundation, American Forests, and the Canadian Parks Council (all of which serve on the SFI Board).[50]

Unlike SFI, the FSC included environmental groups such as Greenpeace among its founders.[51][52] The National Wildlife Federation and World Wide Fund for Nature (WWF) currently serve on the FSC Board.[53] The Sierra Club endorses only FSC.[54]

Critiques of SFI

Marketing practices

On September 9, 2009 the Washington State Forest Law Center, on behalf of the environmental protection group ForestEthics, filed complaints against SFI Inc. with the Federal Trade Commission[55] and the Internal Revenue Service.[55]

The FTC complaint accused SFI Inc. of misleading consumers with deceptive marketing practices. The complaint cited various aspects of SFI's marketing, including its claim that it is an “independent” not-for-profit organization, its dependence on the timber industry for funding, and the vagueness of SFI's environmental standards, which allow SFI-certified landowners to be certified merely because the landowner is complying with state environmental regulations. The 2009 complaint cited SFI's certification as an example of greenwash.

Both the FTC and IRS investigated the complaints made against SFI and found them without merit. No action was taken by either investigative body.

Conflict of interest
See also: conflict of interest

The complaint filed with the IRS requested an examination of SFI Inc.’s non-profit status, based on the argument that SFI benefits the private interests of its corporate landowners and not the public interest, as well as the fact that SFI draws funding from the wood and paper industry.[56] The complaint asserts that in serving the private interests of wood and paper companies that want a "green" image, SFI is inappropriately granted a nonprofit status reserved for public charities.[57]

The IRS investigated the complaint as well as conducted a thorough examination of SFI's non-profit status and concluded that it was appropriate and that no further action was required.

Sierra Club complaint

The Sierra Club lodged a formal complaint with SFI,[58] alleging that Weyerhaeuser engaged in risky and irresponsible logging on steep slopes that led to 1,259 landslides in 2007 on SFI-certified Weyerhaeuser lands in Washington state.[59][60] Challenging SFI to back up its claims of "independence" and "rigorous audits," the Sierra Club requested that Weyerhaeuser's SFI certification be revoked.[58]

A peer reviewed landslide study concluded that the Washington State landslides that the Sierra Club attributed to Weyerhaeuser's logging practices were the result of extreme weather conditions such as heavy rainfall and not the result of steep slope logging by the company. Landslides occur on both logged and unlogged sites, but science shows that logging (and logging roads) dramatically increase the risk of landslides.[61]

2022 Greenwashing Complaint

In late 2022, several environmental organizations in Canada filled a complaint with the Canadian Competition Bureau that the SFI was engaged in misleading advertising practices by falsely claiming that it's certifications did not promote sustainable forestry.[62] They accused the SFI of "Greenwashing". In February 2023, the Canadian Competition Bureau launched a probe to investigate.
