Donald Trump has said he will impose tariffs of 25% on all imports from Canada and Mexico, and an extra 10% on Chinese goods, accusing the countries of permitting illegal migration and drug trafficking. …The Canadian dollar fell 0.9% against the US dollar to a four-year low, while the Mexican peso shed 1.3%. The announcements serve as opening shots in Trump’s confrontational new trade policy. “Stiff new tariffs on imports from the US’s three largest trading partners would significantly increase costs and disrupt business across all economies involved,” said a Washington-based think-tank. “Even the threat of tariffs can have a chilling effect.” …Canada’s Chrystia Freeland hailed the bilateral relationship with the US as “one of the strongest and closest . . . particularly when it comes to trade and border security”. They also noted that Canada “buys more from the United States than China, Japan, France and the UK combined”, and last year supplied “60% of US crude oil imports”.
President-elect Donald Trump has vowed to impose sweeping new tariffs on imports, leading his critics to argue that the plan will raise prices and spur inflation. …Nearly 10% of building materials used in residential construction are imported, according to the NAHB… and Canada probably accounts for the bulk of those imports. “Any tariffs that raise the cost of building products will have a detrimental effect on housing affordability,” says NAHB CEO Jim Tobin. ….A steep tariff on Canadian lumber would likely hit homebuilders the hardest—and could raise the prices of new homes, at least temporarily. But observers are skeptical that Trump would impose a steep, immediate tariff on such a fundamental raw material imported from a close ally. NAR’s Chief Economist Lawrence Yun said that it’s possible any tariff on lumber could be imposed over a ramp-up period to allow U.S. timber mills to boost production.
The uptick in fuel prices will likely be temporary, said Ken Simonson, chief economist at the Associated General Contractors of America. However, the broader uncertainty tied to potential trade policy changes under the incoming Trump administration presents a new layer of unpredictability for contractors. …Future prices for crude oil and copper, typically reliable predictors of upcoming producer price index shifts, have recently declined. That indicates the potential for a near-term dip in energy input costs, he said. Contractors have largely benefited from input price stabilization in 2024. As of October, contractors expect their profit margins to expand through the first quarter of 2025. …“The next administration’s trade policy increases uncertainty regarding construction material costs,” said Basu. “Beyond the implications of potential tariffs, input prices may rise in the short term if purchasers rush to import materials prior to the implementation of those policies.”
Mass timber construction …has exploded in recent years, exemplified by buildings like Ascent, a high-rise in Milwaukee, and the new terminal at the Portland Airport. Industry group Woodworks predicts 20% growth in new projects. And passive house design, the ultra-energy efficient methodology of building, has also exploded, with numerous examples of homes, hospitals, high-rises, and even affordable housing built according to the standard. But this progress is at risk with a new Trump administration coming into power. Proposed tariffs by the incoming Trump administration may increase the prices of many items. But for architects and advocates working on more efficient and sustainable buildings, there’s fear that tariffs could impact specific materials and machines that are key to their work. Higher costs from tariffs, may slow down the pick up of these construction techniques, making such buildings more expensive, and slowing down the effort to cut emissions from buildings and the built environment.
On the whole, modern buildings have large carbon footprints, thanks to pollution-heavy concrete, steel, insulation, and more. …So it’s no surprise that the search is underway to shrink emissions. …These developments are mostly written about in scientific research papers and professional journals … here are just a sampling:
IDAHO — Deep in Idaho’s Clearwater Mountains, along the beautiful Lochsa River, is a stand of ancient cedar trees. These trees stand hundreds of feet tall and are hundreds of years old. They were standing long before Europeans arrived in these mountains. …It’s no accident that these old cedar trees are still standing. They remain standing because they are on public lands. Public lands, in which every American has a stake. Surrounding forests, not on public lands, tell a far different story. …Idaho sold off about one third of the land it received from the federal government upon statehood. …We in the West know what state or private ownership means for forests. Stumps, and lots of them. Both entities manage forests to maximize dollars generated. In contrast, public lands mean trees hundreds of years old, superb wildlife habitat, clear, clean water, and unmatched recreation opportunities. And our heritage. 
IDAHO, USA — Placerville is nestled behind Bogus Basin, in the Boise National Forest. The town of 53 is known for its forest solitude – but that isn’t what home insurance companies are looking for. Resident Steve Koppes was dropped from his home insurance company a year and half ago, because his home was in a wildfire-prone area. “I didn’t get notification, I didn’t get reasons. I was just dropped,” Koppes said. Koppes had had the same insurance for years, and never had a claim of any kind. …Each city is ranked on a scale by the Idaho Insurance Ratings Bureau, and Placerville has sat at a level eight since 2010. “The higher the number, the worse off you are,” Placerville Fire Chief Andrew Bourett said. He has done everything he could to make that rating lower – to make getting home insurance easier – but it’s a challenge because of Placerville’s remote location.
The U.S. Forest Service has released its long-awaited proposal to update the landmark Northwest Forest Plan, but many groups said they were unsure of its future with a new administration coming to power in 2025. The document, years in the making, lays out four alternatives for future management of national forests in Washington, Oregon and California by updating a 1994 law crafted by the Clinton administration. The 630,000-acre Siuslaw National Forest along the central Oregon coast would be heavily affected by any decisions laid out in a final plan. A 120-day public comment period begins now, which the agency says will help shape a final plan. “Much has changed in society and science since the Northwest Forest Plan was created nearly 30 years ago,” said Jacque Buchanan, regional forester for the Forest Service’s Pacific Northwest Region. “We’re amending the plan to address today’s challenges [honoring the] original goals, while enhancing wildfire resilience.”
