With over 200,000 direct jobs at stake, sector calls on the government of Canada to bring the same urgency to lumber as it has to steel, aluminum, and energy.
Canada’s forest sector is disappointed that yesterday’s discussions in Washington concluded without relief for 232-affected sectors, including lumber, as the long-standing Softwood Lumber dispute and recently applied tariffs on Canada’s wood manufacturing industry continue to put operations and jobs at risk across the country. While we recognize that the talks were described as substantive and appreciate that these negotiations are complex, after eight years of escalating duties on softwood lumber, the lack of tangible progress for forest sector workers and communities is deeply concerning. With more than 200,000 direct jobs and hundreds of towns and cities across Canada depending on a vibrant forest sector, lumber and forest products must be treated as a greater priority in Canada–U.S. trade discussions.
Our industry continues to face unjustified duties and tariffs that harm forestry workers here at home and raise costs for American families building and renovating their homes. We urge the Government of Canada to ensure that lumber and forest products are clearly on the agenda as talks continue this week. “We simply want to see more urgency, and frankly, we were left wanting more in the post-meeting reports coming out of yesterday’s discussions,” said Derek Nighbor, President and CEO of the Forest Products Association of Canada.
President Trump ushered in new tariffs on imported furniture, kitchen cabinets and lumber on Tuesday, adding a fresh round of levies as he once again threatened to expand his trade war with China. Tariffs ranging from 10% to 50% on foreign wood products and furniture snapped into effect just after midnight. The tariffs are meant to encourage more domestic logging and furniture manufacturing. But critics say that the levies will raise prices for American consumers and could slow industries including home building that rely on materials from abroad. …Critics have called it a stretch to issue the furniture and lumber tariffs under the national-security-related law. …Some American manufacturers lobbied for the tariffs. …Some economists expect the higher price of lumber, along with home furnishings, will slow the pace of home building. That could set back the Trump administration’s goals of improving a weak housing market. [to assess the full story a NY Times subscription is required]
The US is now collecting tariffs on imported timber, lumber, kitchen cabinets, bathroom vanities and upholstered furniture, duties that threaten to raise the cost of renovations and deter new home purchases. …Trump described his wood and furniture tariffs as helping to “strengthen supply chains… and increase domestic capacity utilization for wood products.” Yet 
President Trump has warned of disaster if the Supreme Court overturns his signature tariffs. For starters, it would unleash a bureaucratic nightmare involving reams of refund paper checks. Should the court uphold a US Court of Appeals ruling that Trump’s country-based tariffs are illegal, the government could owe the bulk of the $165 billion in duties collected so far this fiscal year back to companies that paid them. But they won’t have an easy time getting their money back; refunds are typically issued slowly and while the administration could streamline the process, experts fear that’s unlikely. …That means Trump likely won’t part with the funds easily if the tariffs are struck down, and the administration is expected to move quickly to reimpose levies using other legal authorities if that happens. The Supreme Court is expected to hear arguments in November in the case.
WASHINGTON — Prime Minister Carney is set to return to Ottawa today with no deals to remove US tariffs from Canadian goods, but he’s leaving his key minister on Canada-US trade behind to keep pressing the Canadian case. US President Trump lavished praise on Carney during a meeting in the Oval Office on Tuesday and said the prime minister would walk away “very happy.” The president showed no signs of relenting on tariffs, however, and no deal was announced. Carney was scheduled to have a working breakfast this morning with Joshua Bolten, CEO of the Business Roundtable, while Foreign Affairs Minister Anita Anand was set to meet with Secretary of State Marco Rubio. Canada-US Trade Minister Dominic LeBlanc will be staying behind in Washington. LeBlanc told reporters Tuesday that substantial progress was made in the White House talks this week.
TORONTO – United Steelworkers union National Director Marty Warren issued the following statement as Prime Minister Mark Carney travels to Washington, D.C., to meet with US President Trump. …“Canada’s softwood lumber industry is on the brink of collapse. Thousands of workers and entire communities are hanging by a thread while Trump’s tariffs deindustrialize our economy and threaten good jobs across the country. We need urgent action – not more concessions. If free and fair trade in strategic sectors cannot be restored, the federal government must be ready to retaliate and take all necessary measures to protect the integrity of Canadian industrial production and employment. …We cannot allow foreign producers to use Canada as a back door for cheap, dirty, or diverted imports. …If Washington wants access to our market, it must come with respect for fair trade and for the workers who keep our economy running.”
The Canadian Lumber Trade Alliance (CLTA) issued the following statement. …Luc Theriault, President, Wood Products at Domtar and Co-Chair of the Canadian Lumber Trade Alliance, said “The U.S. government’s decision to impose a further 10% tariff – on top of existing duties of 35% – is disappointing. These measures unjustly punish Canadian producers, while also driving up costs for our neighbors in the US.” …“Canadian lumber does not pose a national security risk to the United States. Our industry directly supports 200,000 jobs and sustains over 300 forest-dependent communities across Canada. We will continue to work closely with the Government of Canada to defend against these unfortunate trade actions and to safeguard Canadian forestry jobs.” …In its recent Section 232 proclamation, the US signaled a willingness to pursue negotiations. The Canadian industry is ready to engage. It is essential that the Government of Canada match this commitment and play an active role in defending our industry.
Canada’s forest products sector strongly opposes the US administration’s decision to impose additional punitive tariffs not only on softwood lumber but also on derivative products, including furniture and kitchen cabinets. The targeting of Canada’s forestry products under Section 232 of the Trade Expansion Act is unjustified and disregards decades of evidence and cooperation that confirm Canadian forest products strengthen, rather than threaten, US national security. This broad action further undermines a deeply integrated North American supply chain that supports housing affordability, infrastructure, manufacturing, and shared prosperity and security on both sides of the border. …The new Section 232 tariffs pushes the total duty burden to over 45%. This compounds pressure, distorts markets, threatens jobs on both sides of the border, and escalates trade tensions. …This misguided move risks raising housing costs in the United States and undermines the integrated trade relationship that has provided jobs, investment, and prosperity in both countries,” said Nighbor.
The Trump administration and its advocates have long sold tariffs as a smart and necessary way to reindustrialize the country, bolster national security, and revitalize the economy more broadly. In practice, however, they put tariffs on cabinets and sofas for “national security” reasons, exempt others because of potential political blowback, and do all sorts of other things that likely undermine the economic and security objectives the administration says its tariffs are achieving. And they do it all with little regard for the facts, economics, or law. Throw in some foolish nostalgia (contra the president, furniture manufacturing is today a tiny share of North Carolina’s economy and workforce), and the furniture tariffs make for an almost-perfect example of the canyon between protectionist rhetoric and US tariff reality. The only thing preventing perfection is that there isn’t a “national emergency” or fake “fiscal crisis” attached.
WASHINGTON, D.C. — On Oct. 1, 2025, nine presidents and CEOs representing American manufacturers of hardwood plywood, engineered wood flooring, and hardwood veneer asked President Trump to add their products to the recently announced Section 232 tariffs on wood products. The current 232 tariff proposal focuses on cabinets, vanities, lumber, upholstered furniture, and other products. Section 232 tariffs are trade restrictions, such as import duties, that the President of the United States can impose on goods that are found to threaten national security. According to the group of companies, more than 100,000 American manufacturing jobs are threatened by the “flood of dumped and subsidized decorative hardwood product imports from outside of North America.” The group pointed to the news that Roseburg Forest Products had closed its last hardwood plywood mill and exited the hardwood plywood market as a result of these imports, which the company said dominate 80% of the U.S. market.
Much of the federal government shutdown in the early hours of Oct. 1 after federal lawmakers failed to reach a funding deal. If the shutdown persists, work related to federal data reporting, rulemakings and other regulatory initiatives could face delays. Ahead of the shutdown, many federal agencies published contingency plans on how work at those agencies may be impacted in the short term. …The USDA is expected to furlough 42,256 of its 85,907 employees, equating to more than 49% of the agency’s workforce. Data products and website updates offered by the USDA’s National Agricultural Statistics Service and Foreign Agricultural Service are among agency activities that are expected to cease during the funding lapse. …FAS also publishes a variety of data of interest to bioenergy producers, including monthly export data on ethanol, distillers grains, biodiesel and wood pellets. FAS also publishes reports that provide insight on foreign markets for biofuels and wood pellets. 
The Trump administration on Monday announced tariffs on imported wood products, targeting softwood lumber, timber, kitchen cabinets, vanities and upholstered furniture. …Trump’s proclamation said wood product imports were weakening the US economy, resulting in a persistent threat to the US supply chains and harming the domestic wood industry. “Because of the state of the United States wood industry, the US may be unable to meet demands for wood products that are crucial to the national defense and critical infrastructure,” the proclamation said. …Critics of the tariffs have voiced concern that the new duties will inflate costs for American consumers and builders. Former US Rep. Matt Cartwright, (D-Pennsylvania), said safety will suffer as a result of the new tariff on imports of trucks. …“A lot of these companies are already on shoestring budgets, and unfortunately the first thing that gets cut when costs go up is safety,” Cartwright said.
NEW ZEALAND — News that US President Trump imposed a tariff of 10 percent on imported timber has come as a relief to industry, which expected a higher figure. Mark Ross, chief executive of the Wood Processors and Manufacturers Association, said it was a relief as they thought it would be higher. “We’ve been working through the essential impact of a tariff on our products since March this year so it wasn’t a shock because we were, at one point, expecting a 50% tariff. “So 10% is a bit of relief. It is still going to have a financial impact on the wood processing industry in New Zealand. …Ross said they were working with exporters to work out how to handle the extra costs. …Ross said the United States was New Zealand’s third-largest export market and continued to grow.
Lumber futures rose past $610 per thousand board feet in mid-October, approaching monthly highs as markets priced in tighter near-term supply and looming trade restrictions. Under newly announced US Section 232 tariffs that take effect on October 14th, imported softwood lumber will face a 10% duty and finished wood goods such as cabinets and furniture will face higher levies, prompting importers to front-load purchases and draw down inventories. Domestic output is also constrained as sawmills run cautiously after years of underinvestment, logging curbs in sensitive regions and slow capacity restarts have limited production. The cost and delay of switching suppliers is material given that Canadian lumber, which supplies much of US demand, already carries elevated antidumping and countervailing duties, intensifying the supply squeeze.
North America’s softwood lumber market looks likely to end 2025 no more settled than it was at the beginning. Producers and buyers alike continue navigating a landscape shaped by fluctuating demand, shifting trade patterns, and an uncertain housing outlook. Despite modest production declines in early 2025, the lumber market remains oversupplied. Mills across the US and Canada are contending with high inventories built up earlier in the year. Expectations of tariff hikes spurred an early rush of exports from Canada to the US, flooding the market while demand was soft. However, in the first half of 2025 softwood lumber exports from Canada to the US declined, while US imports from Europe in the first seven months of 2025 increased by 6% year-over-year. Underlying these supply pressures is a US housing market stuck in the doldrums. August saw an 8.5% decline in overall housing starts, with single-family construction down nearly 7%.
President Trump unveiled sweeping tariffs on imported lumber and wood products that his administration says are needed to protect the US economy and boost domestic manufacturing. Starting Oct. 14, softwood lumber will face 10% duties, while kitchen cabinets, bathroom vanities, and other finished wood goods will be hit with 25% tariffs that rise further in January. The biggest blow will fall on Canada, the US’s top lumber supplier, whose lumber exports are already subject to separate duties totaling 35.19%. …Though Canada dominates exports of lumber to the US, many other countries export wood products to the US. The Section 232 tariffs on lumber and wood products affect them in varying ways; some countries benefit from trade deals with the US that cap the rates, and others bear the full brunt. …Though lumber accounts for less than 20% of building costs, the National Association of Homebuilders has long said that restrictions on Canadian lumber translate to higher construction costs.

It’s hard to find anything good to say about Canadian forestry stocks right now. Some of the biggest names in the sector have been on a downward slide for the past three years. … But the onslaught of grim news has highlighted some bargains. …Okay, the definition of attractive rests on an assumption that risk-averse investors might not want to embrace just yet: Despite Mr. Trump’s bluster, the US still needs Canadian lumber in a big way to feed its lumber-intensive home construction industry. Says who? The National Association of Home Builders, for one. …Some analysts believe that US forestry companies will struggle to replace Canadian softwood. Ben Isaacson, at Bank of Nova Scotia, estimates that US producers would have to build 50 new mills to become fully independent of Canadian lumber. Just two companies build the specialized equipment required in mills. They would struggle to supply even two mills a year. [to access the full story a Globe & Mail subscription is required]
Although we are skeptical how effective the C$500 million in “transition” funding will be, the C$700 million in loan guarantees, which are clearly designed as a short-term lifeline for companies to weather the storm, seem pretty meaningful to the Canadian industry at first glance. …If Canadian producers were to simply absorb the incremental duty rate increase, using today’s FOB price for most Canadian softwood lumber and last year’s export volumes to the US translates to a “just pay it” cost of C$1.6-1.7 billion in additional duty payments over the next 12 months. Canadian mill operators are not in a financial position to simply absorb an additional 21-percentage-point increase in duties, so this is an extreme estimate of the true cost. Mills will curtail output rather than continue producing at heavy losses until prices adjust accordingly. Additionally, there is usually some degree of passthrough from the buyer to the seller.
The softwood lumber trade dispute between the US and Canada, which has led to ever-higher US import duties on Canadian lumber, has lasted for decades. …Canadian lumber has the backing NAHB, which sees lumber tariffs as exacerbating high costs for builders and worsening the US housing affordability crisis. There is currently a “Wall of Wood” in the US, after Canadian producers increased shipments to the US in anticipation of the hike to existing ADD and CVD duties in August. Expectations that a large increase in duties would force the closure of Canadian sawmills, lead to shortages, and a boost in lumber prices, overlooked the current weak US demand for lumber, according to Matt Layman. …As US homebuilders now face additional tariff-driven costs, including a 50% tariff on cabinets and vanities, it’s hard to see the lumber demand situation improving, even if more Canadian suppliers have to curtail production or close sawmills.
Lumber futures prices are trading higher after President Trump slapped a 10% tariff on wood imports. Lumber prices have been on a rollercoaster this year, lifted by higher import taxes and tugged lower by the deteriorating housing and construction markets. …Trump’s executive order said the additional 10% tariff, which will also raise the price of lumber from European suppliers like Germany and Sweden, is aimed at protecting domestic sawmills. …Analysts expect the tariff to benefit domestic sawyers and timberland owners, such as Weyerhaeuser and PotlatchDeltic, at the expense of competitors north of the border, who have been losing US market share because of the duties, challenges supplying their sawmills with logs and the abundance of cheap US pine. “Canadian lumber producers’ cash costs should further increase, resulting in capacity closures and a tightening of lumber supply-demand dynamics,” said Michael Roxland of Truist Securities.

The Trump administration’s latest tariffs on housing materials could raise the average cost of building a single-family home by nearly $9,000, according to a report Tuesday from UBS. Research analyst John Lovallo said the new levies include “an incremental 10% Section 232 tariff on softwood timber and lumber imports, as well as 25% levies on kitchen cabinets, vanities and upholstered wood products.” UBS estimates the lumber tariff will add about $720 per home, while cabinet and vanity tariffs could tack on another $280. Upholstered wood products were not included in the calculation because they are generally purchased by homeowners rather than builders. “As a result, we now estimate the total tariff impact on the cost to construct an average home at approximately $8.9K,” Lovallo wrote. …“Importantly, we continue to believe this cost impact will be spread throughout the entire housing value chain, with the builders perhaps best positioned to push back on suppliers,” he said.
In 2024, vinyl siding was the most used principal exterior wall material for homes started. It holds just over a quarter share of homes, slightly surpassing stucco for the first time since 2018. …Vinyl was followed closely by stucco at 25%, and by fiber cement siding (such as Hardiplank or Hardiboard) at 23%. Each of these materials holds about a quarter of the market, with another 16% held by brick or brick veneer. Far smaller shares of single-family homes had wood or wood products (6%), stone, rock or other stone materials (1%), other (1%), or cement blocks (.2%) as the principal exterior wall material. …The strongest trend has been the growing popularity in fiber cement siding. The share of exterior siding material for fiber cement siding has increased by 5.5 percentage points in the last ten years…. Also notable is the decline of brick siding, from almost a quarter of homes in 2012, to just 16% in 2024.){kind=logo}
In the third quarter of 2025, the NAHB/Westlake Royal Remodeling Market Index (RMI) posted a reading of 60, up one point compared to the previous quarter. With the reading of 60, the RMI remains solidly in positive territory above 50, but lower than it had been at any time from 2021 through 2024. Overall, remodelers remain optimistic about the market, although slightly less optimistic than they were at this time last year. The most significant headwinds they are facing include high material and labor costs, as well as economic and political uncertainty making some of their potential customers cautious about moving forward with remodeling projects. The small quarter-over-quarter improvement is consistent with flat construction spending trends and the current wait-and-see demand environment.
WASHINGTON, DC – Fannie Mae published the results of its September 2025 
President Donald Trump has reignited debate over the nation’s housing shortage, calling on Fannie Mae and Freddie Mac to spur a wave of new home construction. Trump accused large homebuilders of “sitting on 2 million empty lots, a record,” and likened their behavior to OPEC’s control of oil prices. …“I’m asking Fannie Mae and Freddie Mac to get Big Homebuilders going and, by so doing, help restore the American Dream!” The president’s comments come as housing inventory has rebounded from historic lows in 2022, but builders continue to face limited incentives to ramp up construction. …Since taking office, Trump has made housing a central policy focus, including an executive order for emergency price relief and a campaign to pressure the Federal Reserve for lower rates. …Despite Trump’s calls, the mechanics of how Fannie and Freddie might spur more homebuilding remain unclear. 
President Trump’s latest round of tariffs aimed at wood, furniture and other household furnishings could drive up the cost of building and owning homes, further weighing on an already weak housing sector. Analysts said the steep levies could aggravate the nationwide housing shortage by slowing the pace of new home construction. The higher costs, as well as hefty tariffs on steel and aluminum that went into effect in June, could also dampen any jolt the housing market might have derived as the Federal Reserve begins to lower interest rates. …“These tariffs are really hard to understand given that the president has said to his supporters, ‘I want to bring down inflation, I want to bring down interest rates,’” said Anirban Basu, at the Associated Builders and Contractors. …And there could be ripple effects, including higher prices for home insurance because houses and their components would cost more to replace.

While sustainable solutions are facing drastic funding cuts, mass timber as a sustainable construction material is steadily gaining traction across the US. Construction using mass timber began in 2015 in the US, and since then the number of projects has grown about 20% annually. Today, over 2,500 mass timber projects are built or in progress in the US, including corporate offices for companies such as Google, Microsoft and Under Armour. …“We have lots of tech firms and big companies that say, ‘Hey, we’re battling it out for workers. We want the best space possible,’” said Bill Parsons, COO at WoodWorks. …Legislation that promotes and programs that fund mass timber, such as the Mass Timber Federal Buildings Act and the Wood Innovations Grant Program from the USDA, are still progressing. …Studies have shown that living or working in a mass timber building improves occupants’ mental health and well-being, even lowering their blood pressure and heart rates.

US civil society groups are urging the European Commission to resist Washington’s pressure to delay the EU’s deforestation regulation (EUDR) or tweak the rules to grant the country preferential treatment, according to a letter seen by Euractiv. The missive, sent this morning to Commission President Ursula von der Leyen and the Commissioners responsible for green rules, the economy and trade, warns against any backtracking. “We are particularly concerned by the Commission’s apparent willingness to offer the U.S. special treatment under the EUDR as part of ongoing EU-U.S. trade negotiations,” the letter reads. The organisations refer to the joint statement issued by Brussels and Washington in September, which labels the US as posing “negligible risk to global deforestation.” Rick Jacobsen, senior manager for commodities policy at the US NGO Environmental Investigation Agency, told Euractiv that US interests have “ramped up the pressure campaign” to weaken the law before it even comes into force.
ATLANTA — Forest Stewardship Council US announced the approval of the revised 
Despite the Trump administration’s pledge to aggressively clear overgrowth from national forests, the U.S. Forest Service is falling significantly short on wildfire mitigation work. By mid-September, the agency had only treated about 2.2 million acres through thinning and prescribed burns. That’s far short of the over 4 million acres treated during the last year of the Biden administration, and it’s also behind the agency’s annual average over the past decade. Forest Service Chief Tom Schultz blamed “operational challenges” and said agency resources were diverted to help battle blazes in Canada. However, Senator Ron Wyden of Oregon is blaming the slowdown in fuel treatments on the Trump administration firing thousands of Forest Service employees earlier this year. …the government shutdown has stopped wildfire prevention efforts across the country’s entire 193 million acres of national forest land [at] the ideal time for the agency to conduct safe prescribed burns across the West.
Roughly 500 years ago in California’s High Sierra, pine cones dropped to the ground and a cycle began. …Half a millennia later, US Forest Service scientists began testing strategies to save these now ancient and massive trees in the little-known area east of Fresno called the Teakettle Experimental Forest. They had plans to light a huge prescribed burn to clear overgrowth next year. But then the Garnet Fire ignited and scorched all 3,000 federally protected acres on its path through the Sierra National Forest. …Scott Scherbinski, a biologist at the Climate & Wildfire Institute, said “It will be a start-over event for this forest.” …Malcolm North, a Forest Service ecologist said…fires with less intensity can be beneficial in California’s fire-adapted landscapes, but the Garnet Fire, when it burned through in September, may have killed most trees and sterilized the ground — making it unlikely the forest can rebound without intervention.

Drought and insects have killed an unprecedented number of Oregon’s Douglas fir trees during the last decade, costing billions in timber value, damaging infrastructure and ramping up wildfire danger. Beginning in 2015 and accelerating with the 2021 heat dome, roughly 635,000 acres of forest have been impacted by what’s known as Douglas fir “dieback” in southwest Oregon and the Willamette Valley. “It’s hitting trees of all sizes, but it’s hitting larger and older trees the hardest,” Max Bennett, a retired forest researcher with Oregon State University, told members of the Oregon Legislature on Sept. 30. “What we’re seeing now is unprecedented.” The dieback has led to $1.1 billion in lost timber value, $500 million in potential road hazard costs and created a tinderbox of forest fuel capable of spawning the West’s most destructive wildfires, a group of foresters and researchers told the House Committee on Agriculture, Land Use, Natural Resources and Water.
Last April, a pair of teenage boys … set fire to wooden pallets someone had dumped in the woods. Within a few hours it became one of the fastest-moving and most destructive wildfires on record in the New Jersey Pinelands. By the time it was brought under control three weeks later, about 15,000 acres of preserved forest were destroyed, and thousands of people were forced to flee their homes and businesses. Most official accounts of what became known as the Jones Road Fire attribute its ferocious power to the intensifying cycles of drought and heat linked to climate change that continue to affect coastal areas. But forestry experts in New Jersey point to another cause. …On Sept. 18, the New Jersey Pinelands Commission took a big step toward more aggressive management of the state’s Pinelands National Preserve voting to thin out a 12,000-acre stretch of pine and oak woodland adjacent to the wildfire site.
MONTANA — With the federal government in a shutdown, the Forest Service has paused much of the wildfire preparation and prevention work it does on its 193 million acres of national forest. A Forest Service contingency plan, current as of Sept. 30, calls for continued wildfire response. But the work necessary to reduce the fuels for massive wildfires, including prescribed burns, is on hold. …“We were told, ‘No ignitions,’” said a Forest Service fire management officer, who didn’t want to be named for fear of losing his job. “‘Don’t even start.’” The cooler, wetter fall season is an ideal time for prescribed burns and pile burning across the West. …Other significant activities will be delayed during the shutdown, including statewide forest inventories, processing special use permits and reimbursing partners like the states and non-governmental organizations that do forest management work with federal funds.
Given market sentiment and operating rates, in addition to recent mill closures and curtailments, how has demand for wood fiber changed recently and over the past 10 years? …Total capacity of the wood-using U.S. pulp and paper sector declined 18% in the past 10 years. This decline is specific to wood-using mills, excluding facilities that rely exclusively on recycled fiber, but the sector reported drops in all end uses, with reductions in printing and writing capacity falling 49%. This represented over half of the lost capacity nationwide. Newsprint, household/sanitary, and market pulp segments also had notable declines, each representing 10%-16% of the lost capacity. Regionally, capacity reductions in the U.S. South accounted for most of the volume lost (64%), with the U.S. West and North each representing 18%. The West experienced the largest and most severe drop in capacity for a given region, with pulp and paper mill closures and reductions decreasing capacity by 26%.
WASHINGTON — The US Supreme Court on Monday declined to hear a high-profile challenge to Washington’s Climate Commitment Act, marking yet another victory for the state’s keystone climate policy. The lawsuit started with the private operator of a natural gas power plant in Grays Harbor County. The plant is required to buy pollution allowances to pay for the many tons of greenhouse gasses it emits into the atmosphere under the 2021 “Cap and Invest” law. The plant’s owner, Chicago-based Invenergy, sued Laura Watson, then-head of Washington’s Department of Ecology, in late 2022, arguing that the state’s carbon market is unconstitutional. The lawsuit claimed that the state law discriminated against privately operated natural gas plants. In 2023, US District Court Judge Benjamin Settle dismissed the case. The company appealed. …The Supreme Court on Monday denied Invenergy’s petition outright. The justices did not publish any written justification for their decision.
