Enviva aims to provide ‘sourcing transparency’ by unveiling wood supply tracking system
Enviva Holdings, wood pellet giant, today publicly released the first data from its groundbreaking Track & Trace (T&T) programme.
T&T is a proprietary system that enables Enviva to track every truckload of wood the company procures from the forest back to its source, providing a detailed understanding of the characteristics of the wood the company uses. Demonstrating an unmatched commitment to transparency, Enviva is now making that information available to the public.
Moving from coal to renewable energy
“Enviva’s sustainably produced wood pellets provide a cleaner energy alternative to fossil fuels, allowing electric utilities to replace coal and reduce the greenhouse gas intensity of energy generation while providing uninterrupted and dispatchable renewable energy that is there when customers need it,” said John Keppler, Chairman and CEO of Enviva.
“With our Track & Trace programme, Enviva maintains unprecedented data on our wood supply chain, driving sustainable procurement activities and helping us demonstrate and verify our commitment to forest sustainability while creating jobs and supporting economic growth in the American Southeast.”
Enviva makes pellets using low-grade wood from Southern US working forests. Enviva does not use high-grade wood that would otherwise be milled into furniture or construction materials, but procures only low-quality materials such as pulpwood and “leftovers,” including undersized or crooked trees, limbs, tops, wood chips and sawdust.
As an additional component of its commitment to sustainable sourcing, Enviva does not source wood from independently identified bottomland forest ecosystems that demonstrate high conservation value attributes, or from any forest where the landowner plans to convert to a non-forest use.
In a statement, the company said, while Enviva has always had a rigorous system in place for ensuring that suppliers provide the company with wood that meets its sustainability requirements, Enviva has now developed T&T, a one-of-a-kind monitoring programme that tracks all wood received from the forest to its harvest origin.
Today’s public launch of Enviva’s Track & Trace programme comes after years of planning and investment and thousands of hours of effort on the part of Enviva’s professional foresters and the company’s wood suppliers.
Before selling wood to Enviva, a supplier must provide detailed data on the specific forest tract being considered for harvest, including each individual tract’s precise geographic location, acreage, forest type, species mix, age and the share of wood from each harvest that goes to Enviva versus other consumers. Enviva does not accept any wood from a harvest without this information, and the company records the data and verifies the accuracy of its procedures through third-party audits.
T&T data are presented in two ways. First, the Forest Trend Map is based on time-series data from the US Forest Service and displays changes in overall forest conditions in the Southeast US and in each of Enviva’s forest supply areas. Second, the Enviva Wood Supply Map provides detailed information on actual timber harvests around each of Enviva’s facilities during the first half of 2016.
Data include harvest site, landowner type, forest type, harvest type, years since last harvest, the number of acres harvested and the percentage of the harvest volume provided to Enviva for wood pellet production.
The first T&T public release includes Enviva wood purchases from January through June 2016.
Initial T&T findings include:
- Since Enviva opened its first U.S. mill in 2011, the total amount of forested land in its primary supply area has increased by more than 320,000 acres, with the volume of forest inventory on that land growing by 10 percent.
- During the first half of 2016, Enviva procured wood from more than 750 individual tracts in 98 counties in seven southern states.
- During the first half of 2016, Enviva’s wood came from these sources:
- About 72% came from mixed pine and hardwood forests (43%), Southern yellow pine forests (25%) and upland hardwood forests (4%). This wood consists of undersized or “understory” wood that was removed as part of a larger harvest; tops and limbs; brush; and “thinnings” that were removed to make additional room for planted pines to grow.
- About 25% was sawdust, shavings or residuals from wood product manufacturing.
- About 3% came from working bottomland hardwood forests, made up of undersized or “understory” wood that was removed as part of a larger harvest; tops and limbs; brush; and “thinnings.”
- Less than 1% came from landscaping or urban tree maintenance projects.
- On average, the forests on these tracts were 37 years old at the time of final harvest.
“Research shows that sustainably sourced and produced wood pellets can significantly reduce greenhouse gas emissions on a lifecycle basis compared to coal,” said Jennifer C. Jenkins, VP and chief sustainability Officer at Enviva. “Enviva is providing transparency into our sourcing process so that policymakers and other stakeholders can investigate for themselves the responsible wood supply approach that Enviva is taking to ensure the positive environmental impact of our wood pellets.”
