Stemming Illegal Logging with a New LEED Credit
April 2, 2019
Who’s in favor of legally sourced wood?
If you’re raising your hand, you’re not alone: illegal logging is a global scourge that destroys ecosystems and contributes to climate change. It’s carried out by organized crime, and is used to fund civil wars and terrorism. And by some estimates, as much as half the timber in the world is harvested illegally.
But a pilot program in LEED that purports to address the problem doesn’t help at all, according to some non-government organizations. Now these NGOs—which include Greenpeace, the Environmental Investigation Agency, and the World Wildlife Fund—are getting their own day in the sun.
The U.S. Green Building Council (USGBC) has released a new credit called Timber Traceability; through lab testing, it’s designed to help ensure that wood purchased for projects matches the species that the project team specified and purchased. “I’m really excited,” said Jason Grant, an affiliate with the Sierra Club certification and green building team. “We may have something that could scale up and really be impactful.”
To achieve the Timber Traceability pilot credit, project teams have to identify the area of harvest and species of at least 50% by cost of the wood on the project, then order testing—such as DNA, mass spectrometry, or stable isotope analysis—of the actual wood that’s delivered to the site. If it matches, the project earns a point. There are additional requirements for wood products sourced from countries with high risk of illegal logging.
The credit details can get a little complicated, with tiers of achievement based on how far project teams are able to zoom in on the wood’s origins, so the Environmental Investigation Agency will act as an intermediary through the website woodorigin.org, and USGBC has released a guidance document explaining the steps. These include gathering and submitting basic information on all wood products, and gathering and submitting samples and maps of area of origin. USGBC recommends that project teams seek maps for most or all wood products, in case some of their samples ultimately don’t match.
That risk should be fairly low, though, according to Grant. “Specific supply-chain actors are going to need to be positioning themselves by cooperating with the information well in advance,” he explained. “The chances that they are going to submit maps that are fraudulent are pretty small.”
It’s important for building professionals to practice “due care” to comply with strict U.S. laws about illegal timber, and the sample-testing method goes “above and beyond” what most do, said Grant. But other strategies of reducing the risk of purchasing illegal products—like relying on certifications or collecting documentation—“are subject to fraud.” He added, “Laundering illegal timber is extremely profitable—much more profitable than managing timber responsibly.”
