“Here’s a multibillion-dollar question that could help determine the fate of the global climate: If a tree falls in a forest—and then it’s driven to a mill, where it’s chopped and chipped and compressed into wood pellets, which are then driven to a port and shipped across the ocean to be burned for electricity in European power plants—does it warm the planet?

Most scientists and environmentalists say yes: By definition, clear-cutting trees and combusting their carbon emits greenhouse gases that heat up the earth. But policymakers in the U.S. Congress and governments around the world have declared that no, burning wood for power isn’t a climate threat—it’s actually a green climate solution. In Europe, “biomass power,” as it’s technically called, is now counted and subsidized as zero-emissions renewable energy. As a result, European utilities now import tons of wood from U.S. forests every year—and Europe’s supposedly eco-friendly economy now generates more energy from burning wood than from wind and solar combined.”

“Nevertheless, the global transition away from fossil fuels has sparked a boom in the U.S. wood-pellet industry, which has built 23 mills throughout the South over the past decade, and is relentlessly trying to brand itself as a 21st-century green energy business. Its basic argument is that the carbon released while trees are burning shouldn’t count because it’s eventually offset by the carbon absorbed while other trees are growing. That is also currently the official position of the U.S. government, along with many other governments around the world.”

…

“critics of the industry have suggested an alternative climate strategy: Let trees grow and absorb carbon, then don’t burn them. Deforestation is a major driver of climate change, and the United Nations climate panel has warned that the world needs to end it worldwide to meet the ambitious Paris emissions targets for 2050.”

…

“European experience shows that general policies to promote renewables can spark a massive shift to wood-burning if biomass isn’t specifically excluded.”

“Enviva’s product would not exist without loggers who clear-cut forests into barren fields with motorized “feller-bunchers,” but the company tries to emphasize that its business is about growing trees as well as killing trees. Enviva requires the landowners who supply its wood to promise to replant their forests, and it uses GPS technology to track and trace every harvest to see if they comply. The company has also committed to help protect 35,000 acres of threatened bottomland hardwood forests and restore 5,000 acres of natural longleaf pine.”

…

“Jenkins wants the public to see the big picture: Southern forests are growing overall, with more trees being planted than cut, and Enviva’s demand for wood helps encourage landowners to keep their forests as forests. The Southeastern U.S. produces one-sixth of the world’s timber, and less than 4 percent of that harvest ends up as pellets.

…

“one thing both sides agree on is that it matters what kind of wood ends up in the pellet mills, and what would have happened to that wood otherwise. Policymakers and academics have made all kinds of theoretical assumptions, but it’s not hard to find the reality on the ground.”

…

“In the decade since Enviva started manufacturing pellets, the Dogwood Alliance has repeatedly exposed gaps between the company’s sustainability rhetoric and its actions. In 2018, for example, a Dutch TV station working with Dogwood followed some logs from another cypress swamp near the Virginia border back to Enviva’s mill. Smith and I returned to the scene three years later, and while the deforested high ground around the swamp had been recolonized by a thick tangle of grasses, bushes and scrub oak, there wasn’t much growing back in the low-lying wetlands, just some sad-looking stumps poking out of the murky water. Smith warns that if governments keep subsidizing the conversion of trees into energy, enormous swaths of environmentally valuable forests around the world will end up looking like that.

Enviva officials say they no longer accept any cypress wood at their mills, or for that matter any other wood harvested from ecologically sensitive areas. They say they now source only 3 percent of their wood from the increasingly rare bottomland hardwood forests that are such culturally resonant symbols of the South—and only from “non-sensitive” ones. But Jenkins admits the company made some questionable sourcing decisions in the past.”

“what’s clear from talking to people in North Carolina, and from a few hours standing outside two Enviva mills watching logging trucks come and go, is that much of the wood that gets pelletized isn’t unmerchantable waste wood. It’s pulpwood—whole pine and hardwood trees as well as wood chips that could otherwise be sold to paper mills. It’s not thick or unblemished enough to turn into telephone poles, houses or high-quality furniture, but much of it is fine for Amazon boxes, toilet paper and the fluff inside diapers; one member of Enviva’s sustainability team described it as Walmart wood rather than Gucci wood. I later spent an hour outside a nearby paper mill watching what kind of wood arrived there, and the trucks were bringing in the same kind of logs they brought to Enviva.

That means Enviva isn’t just cleaning up around the edges of the logging industry—it’s increasing demand for wood in the South. And that means additional trees would need to be logged to feed the paper mills that are losing trees to Enviva; the increased demand for pulpwood will require an increased supply of pulpwood. Even if new trees are planted in their place, many studies suggest they will take decades, and in some cases centuries, to absorb enough carbon to “pay back” the carbon debt from burning the older trees. That’s a problem, because scientists don’t believe the world can wait decades, much less centuries, to cut emissions.”
