Just one more storey? The embodied greenhouse gas impacts of adding height, slab thickness, building code and design tranches is a paper written by Avery Hoffer of the Department of Civil and Mineral Engineering, University of Toronto, which contradicts just about everything I have written about building height. Hoffer, seen presenting his work last year, concludes: “Don’t fear height, fear bad design.” …Hoffer says on his concluding slide, “historical skepticism of tall buildings does not hold up when evaluated through the lens of embodied GHG emissions.” I wrote in my recent book, “When you look at the world through the lens of upfront carbon, everything changes.” Same lens, opposite conclusion! Hoffer references my two favourite studies: Francesco Pomponi’s “Decoupling density from tallness in analyzing the life cycle greenhouse gas emissions of cities”, which found that high-density low-rise buildings have half the life-cycle greenhouse gas emissions of high-density high-rise buildings.
The Softwood Lumber Board has released its Q3 2025 Report, highlighting significant progress tied to its new strategic plan. This quarter, SLB-funded programs advanced a coordinated strategy centered on high-opportunity sectors—1-8 story multifamily, commercial, K-12 education, and the fast-growing industrial segment—while accelerating project conversions, strengthening building code support, scaling post-secondary education, and expanding outreach in key cities.
The Canadian Wood Council (CWC) welcomes the announcement made today by the Honourable Tim Hodgson, Minister of Energy and Natural Resources. The event celebrated funding for projects that strengthen Canada’s forestry sector and foster innovation in wood-based solutions. CWC received $8.5 million since 2023 to expand the use of wood-based products, broaden education on wood construction and contribute to the advancement of the National Building Code. …This funding has allowed CWC and its WoodWorks program to support design and construction professionals with expert resources, tools, and guidance that help accelerate the adoption of wood construction nationwide. As we continue this work, we will help catalyze sustainable demand for construction solutions that are not only innovative but also replicable and rapidly deployed, approaches that will help address Canada’s housing and affordability challenges at scale.

Zoom Seminar | November 18| 11:30am – 1:00pm| This seminar helps leaders and teams learn to use artificial intelligence to enhance productivity, communication, and operational efficiency. Rather than replacing people, AI can act as a digital teammate, handling routine or repetitive work so humans can focus on creativity, decision-making, and critical thinking. Participants will explore practical ways to use AI tools like ChatGPT, Copilot, and others to streamline workflows in areas such as administration, project management, customer service, and content creation. You will learn: How AI tools like ChatGPT and Copilot work; common misconceptions; How to give clear, effective instructions to AI. Examples of strong vs. weak prompts; Examples of AI applications for administrative tasks, writing, and increasing productivity; and What to include in an internal AI-use framework: approved tools, privacy, and accountability. Safe and unsafe examples. $29 per person (you do not need to be a BC Wood member to participate – Limited to participants from Canada only)
When Prime Minister Mark Carney toured Intelligent City’s advanced manufacturing facility in Delta, B.C. this spring, it was more than just another campaign stop. It signalled that prefabricated and modular construction has moved from the margins to the mainstream of Canada’s housing conversation. That recognition is overdue. If we are serious about tackling Canada’s housing affordability crisis by delivering more homes at scale, governments need to stop paying lip service to the huge potential of off- site construction and start putting it into policy and practice. …First, governments should publish a multi-year prefabricated housing procurement roadmap. Off-site manufacturing depends on predictable, portfolio-scale demand. A provincial roadmap in British Columbia, for example, that consolidates housing needs across ministries, Crown agencies, and municipalities would give factories the confidence to invest in automation, skilled labour, and supply chains.
The audience of dedicated urbanists at Vancouver’s Robson Square Theatre was startled earlier this year when the first speaker at a debate about mass timber—which B.C. has been promoting vigorously—said it isn’t the for-sure climate-change silver bullet that everyone likes to think it is. Adam Rysanek, a UBC professor of environmental systems who specializes in energy efficiency, poked hard at the assumption that, because everyone thinks of mass timber as just wood—a plant! that comes out of the ground!—it must be natural and environmentally friendly and surely better than concrete. But Rysanek kept making the point at the Urbanarium debate that those ideas are not fully proven. A study he cited, which aimed to factor in all the uncertainties of carbon emissions in different types of building materials, found there is not a clear answer yet about the differences between mass timber and concrete.
EDMONTON, AB – Celebrated for its pioneering mass timber design and construction, commitment to safety and collaborative excellence, Limberlost Place has been named the Global Best Project of the Year by Engineering News-Record (ENR). In addition to PCL Construction and partners taking home the top honour, PCL was also awarded ENR’s Global Best Projects Award for Limberlost Place in the Education/Research category. …Ontario’s first institutional building of its kind, George Brown Polytechnic’s Limberlost Place has set a new precedent for mass timber construction as a model for sustainable, green building innovation. Located in Toronto, Ontario, the 10-story mass timber, net-zero educational facility integrates first-of-its-kind solutions including: Groundbreaking slab band structural system that advances the use of mass timber in multi-storey buildings; North America’s largest mass timber columns soaring three stories tall; and a striking mass timber feature stair, spanning levels three to five as a centerpiece of architectural design.
TORONTO — The Ontario government has launched a new working group to guide the implementation of the 
…Biophilia — a concept that’s been introduced in the pages of Health & Home before — is a term coined by the sociologist Erich Fromm and later adopted by biologist Edward O. Wilson in a 1984 book of the same name. Bill Browning, co-founder of the New York City-based sustainability consulting firm Terrapin Bright Green and chair of the Biophilic Institute, defines it as the “innate affiliation of humans to other living organisms and lifelike processes.” …Browning’s firm published a paper in 2022 titled “The Nature of Wood,” which distilled the available research on why people tend to gravitate to wood as a natural material. …Browning’s company has summarized some of biophilia’s high-level takeaways in a paper called “14 Patterns of Biophilic Design: Improving Health & Well-Being in the Built Environment.” In it, they outline how light, water, airflow and even a very primal sense of safety can positively affect cognitive performance as well as our mind-body relationship.
Mark Latino is the CEO of Lee Display, a Fairfield, California-based company… that still makes artificial Christmas trees, producing around 10,000 each year. Tariffs shone a twinkling light this year on fake Christmas trees — and the extent to which America depends on other countries for its plastic fir trees. Prices for fake trees rose 10% to 15% this year due to the new import taxes, according to the American Christmas Tree Association, a trade group. Tree sellers cut their orders and paid higher tariffs for the stock they brought in. Despite those issues, tree companies say they aren’t likely to shift large-scale production back to the US after decades in Asia. Fake trees are labor-intensive and require holiday lights and other components the US doesn’t make. …About 80% of the US residents who put up a Christmas tree this year planned to use a fake one. …That percentage has been unchanged for at least 15 years.
Schools built with mass timber have recently opened to positive community response in the Seattle, Renton and Highline school districts, and another is under construction in West Seattle. … Throughout the United States and Canada, about 150 educational projects have already been built with mass timber. Mass timber products such as Glulam and Cross-Laminated Timber are made from lumber stacked in layers to create large components — columns, beams and panels that become the structures of buildings of all types. These large building components drive efficiency in construction while reducing the carbon footprint. In Washington, mass timber can now be used in buildings up to 18 stories, a renewable, resilient alternative to steel and concrete. The Pacific Northwest is well-positioned to be a leader in this industry. …structures made from mass timber, where the wood remains exposed, have 
Payson sits in one of the most fire-prone regions in the country, yet the town council has repeatedly declined to adopt fire-hardening requirements for new homes. The town several years ago approved a Firewise landscaping code aimed at thinning overgrown properties and removing vegetation touching buildings. However, the council has twice rejected a Wildland-Urban Interface (WUI) building code, most recently after firefighters urged the council to adopt standards for new construction. Builders raised concerns about cost, and the council again declined to move forward. A collection of studies suggests those concerns may not align with the data. Research from federal agencies, economists and wildfire specialists shows WUI codes add little to the cost of new construction, save money over time and significantly reduce the likelihood of homes burning in a wildfire. The research also points to major long-term savings for taxpayers, who shoulder growing federal firefighting costs in high-risk areas.
SALT LAKE CITY — Homeowners in high wildfire risk areas should soon expect home assessments and a new fee. HB48 Wildland Urban Interface Modifications requires the Utah Division of Forestry, Fire and State Lands to draw a high wildfire risk boundary across the state. The division will inspect homes within the boundary for fire risk, and property owners will pay a fee based on their risk and square footage, which will cover the cost of the program and lot assessments. State Wildfire Risk Reductions Programs Manager Joseph Anderson said the assessments will focus on the vegetation surrounding the home and the materials used in the structure. “The goal is to remove any vegetation or anything that could catch an ember and allow that ember to burn and catch the structure on fire,” Anderson said. The bill comes after catastrophic wildfires across the West, like the California Eaton Fire from January 2025. 
Bamboo tissue’s green image fades once you factor in coal-powered manufacturing. Bamboo tissue paper produced in China has become a popular option for shoppers looking to reduce their environmental impact. Despite its green reputation, new research suggests these products may not deliver the climate advantages many consumers expect. In some cases, bamboo tissue may even have a greater environmental footprint than tissue made in the United States. A recent 
The smell of an old book … escapes as a cover is eased open or a stiff page lifted, settling briefly in the air between hand and paper. In libraries and second-hand shops, it is a faint but persistent smell… It is often associated with comfort and habit, yet it has a material basis. Conservators and chemists treat it as evidence of physical change. Paper, ink, glue, and binding age continuously, releasing compounds that remain present long after printing. What is sensed is the slow chemistry of use and storage. …Paper accounts for much of the smell associated with old books. From the nineteenth century onwards, most paper was produced from wood pulp containing cellulose fires and lignin. Over time, these components undergo chemical change. Cellulose chains fracture and shorten. Lignin oxidises and breaks into smaller fragments. These processes release volatile organic compounds that drift from the page surface.
Futamura, a Japanese manufacturer of cellulose films and packaging products, has announced a solution to help reduce the quantities of microplastics generated from glitter products. Microplastics are defined as plastic particles less than 5mm in size, which can be either intentionally manufactured at that size (primary microplastics) or created when larger plastic items break down (secondary microplastics). Glitter has been particularly criticised in recent years for its contribution to microplastic pollution in oceans and soil. According to Futamura, biodegradable glitter can be created from its NatureFlex materials [wood pulp], which will safely degrade in the environment it was disposed of after use without producing harmful microplastics. …Currently, glitter based on conventional plastics can still be sold into cosmetic applications due to a transition period granted under the EU’s Microplastics Regulation. However, once this period ends cosmetic applications will also be banned.
