President Donald Trump is promising to unleash the US timber industry by allowing companies to raze swaths of federally protected national forests.
The executive order — which calls for the ramping up of the domestic timber production to avoid reliance on "foreign producers" — was followed three days later by sweeping 25% tariffs on Canadian products, including lumber.
The United States has an "abundance of timber resources that are more than adequate to meet our domestic timber production needs," the executive order says.
However, it's more complex than simply swapping out Canadian imports for homegrown timber, said industry experts, who warned tariffs could end up increasing lumber and building costs — and even push up housing prices for consumers.
Meanwhile, environmental groups say clearcutting national forests will pollute the air and water, endanger wildlife and exacerbate climate change. "Trump's order will unleash the chainsaws and bulldozers on our beautiful, irreplaceable federal forests," said Randi Spivak, public lands policy director at the Center for Biological Diversity.
"This is a particularly horrific move by Trump to loot our public lands by handing the keys to the kingdom over to big business," Spivak said.

Ocean governance reforms now carry direct consequences for sustainable construction and environmental sustainability in construction. The UN High Seas Treaty and proposed protections for the Antarctic Peninsula introduce stricter environmental impact assessments for offshore and coastal developments, signalling an era of detailed whole life carbon assessment in marine-related infrastructure. Developers of subsea cables, interconnectors, and CO₂ pipelines will contend with extended consenting processes and biodiversity restrictions that influence material selection, eco-friendly construction practices, and low carbon design decisions across multiple jurisdictions. The evolution of marine spatial planning aligns with circular economy in construction principles, recognising supply-chain carbon exposure as both a design and compliance issue.
Trade policy disruption poses further challenges to sustainable building design. Prospective tariffs on low-carbon materials—such as green building materials, steel, engineered timber, and heat-pump components—threaten project timelines and budgets. Anticipated responses include regional procurement strategies, adoption of sustainable material specification, and more rigorous evaluation of embodied carbon in materials and life cycle cost performance. Demands for verifiable environmental product declarations (EPDs) and building lifecycle performance metrics are expected to rise as clients seek transparency for carbon neutral construction targets.
Climate volatility is reshaping low-impact construction strategies, particularly in flood-prone and mountainous regions. Designers must adopt adaptive lifecycle assessment frameworks that prioritise redundancy, attenuation, and slope stability. These approaches support net zero whole life carbon goals and reduce the carbon footprint of construction, reinforcing resilience and resource efficiency in construction.
The policy debate on decarbonisation is shifting toward measurable outcomes. Governments are preparing performance-linked procurement and finance mechanisms that embed whole life carbon benchmarks into material supply chains. The accelerating move toward net zero carbon buildings, green construction, and BREEAM V7 standards signals the transition from intent to implementation. Markets for low embodied carbon materials and circular construction strategies are scaling at pace, defining a new baseline for sustainable building practices and comprehensive whole life carbon accountability across the global built environment.
