The federal government has pushed its target to achieve a net-zero electricity grid back 15 years to 2050 as part of new clean electricity regulations announced Tuesday — though officials maintain that target date was always the goal. Canada had previously signalled an aim to fully decarbonize electricity grids by 2035. But some provinces, namely Alberta and Saskatchewan, said that was simply not doable. Alberta Premier Danielle Smith swiftly responded to Ottawa’s plan by saying her province would immediately mount a legal challenge because the regulations wade into provincial jurisdiction. …The country’s electricity grid is already substantially green, with 85% of Canada’s power supply coming from non-emitting sources. But four provinces — Alberta, Saskatchewan, Nova Scotia and New Brunswick — still rely on coal and natural gas. Committing to a net-zero electricity grid is an easy move for the other six provinces, which are already more than 90 per cent of the way there.
New actions are being implemented to help more people find affordable homes in the communities where they live and work. …Starting Jan. 1, 2025, the B.C. home-flipping tax will be in place to discourage investors from buying housing to turn a quick profit. People who sell their home within two years of buying will be subject to the tax, unless they qualify for an exemption, such as divorce, job loss or change in household membership. It is expected approximately 4,000 properties will be subject to the tax in 2025. All revenue from the tax will go directly into strengthening housing programs and building new affordable homes in B.C. …Other measures to help make homeownership more accessible and improve the supply of housing, which came into effect April 1, 2024, are new thresholds for the first-time homebuyers’ program and the newly built home exemption.
A group of UBC academics has compiled a list of ways to ensure this Christmas has as little effect on the environment as possible. …“Natural Christmas trees are more sustainable than artificial ones, which produce three times the emissions,” says Jiaying Zhao, associate professor in the department of psychology and the Institute for Resources, Environment and Sustainability. She—also suggests renting potted Christmas trees. Johan Foster, a professor of chemical and biological engineering, says most fake Christmas trees contain polyvinyl chloride or PVC, which sheds microplastics indoors and is not good for children or pets. …Guangyu Wang, an associate professor in the faculty of forestry, suggests using a real Christmas tree and planting it in a biodegradable pot, which eliminates the environmental impacts of disposal, allows the tree to continue sequestering carbon and prevents methane emissions from trees decomposing in landfills.
Reaching the lumber industry’s vast market share potential will require growth of a variety of lumber-based and hybrid building systems, but steel-timber hybrid construction represents one of the greatest areas of opportunity. According to an analysis for the SLB by Forest Economic Advisors, steel and mass timber warehouses represent a potential annual volume of 2.4 BBF, while steel and mass timber multifamily projects represent 3.6 BBF of annual opportunity. The SLB has been working with the Council on Tall Buildings and Urban Habitat and constructsteel to unlock this opportunity, beginning by launching the Steel-Timber Hybrid Buildings Conference in 2022. The partnership continued this year with the launch of “Steel-Timber Hybrid Buildings: Case Studies,” a CTBUH research report funded by the SLB and constructsteel. The organizations celebrated the launch in September at the CTBUH 2024 International Conference
LEESBURG, VA. – The American Wood Council (AWC), International Code Council and WoodWorks have joined together to release an updated version of the free app to calculate maximum allowable heights and areas for buildings of various occupancy classifications and types of construction. The 
A material that’s been around since people built shelters – wood – is increasingly being proposed for low- and mid-rise buildings. Companies behind these “mass timber” projects say that wood is a lower-carbon alternative to steel or concrete and brings other benefits, such as faster construction time and lower cost than concrete and steel. Advocates say the wood materials, made of compressed layers of wood with glue, offer good fire safety as well. As an economist who studies forestry and natural resources, I took an interest in this building trend when I heard that a local bar on campus was going to be replaced by a 13-story building made out of wood. I see any increase in the use of wood in buildings as positive for reducing the substantial carbon footprint of buildings. But it is critical to consider where wood is sourced and whether forests are managed sustainably.
Silver Maple Aviation is a new entrant to the aviation infrastructure sector but has already left an indelible mark on the industry. “Silver Maple Construction’s roots are in very high-end, tricky residential and subcommercial projects, and is new to the aviation space,” said Sean Flynn, company president. …Silver Maple Aviation is known for its ingenuity and fortitude. A project that embodies the company’s tenacity is a 210-foot-long-by-170-foot-wide hangar that was built for a private flight department in New Hampshire. “The Concord hangar project is what I believe to be the largest wooden structure, period, on the east coast,” he said. “We were asked not necessarily to build a green hangar but to build a massive hangar very quickly. …we went down the mass timber hangar route, which at the time was about how quick we could get the materials, although I had already been studying up on mass timber in general.”
Answer: Yes, at least for well-being. Wood has many qualities that are impossible to replicate. There are many academically approved studies highlighting the positive impact of forests and trees on humans. Recently, there has also been high-quality research on the benefits of using wood as a construction material. Wood is a restorative material that supports well-being. A Slovakian study found that wooden materials with brownish colours are ideal for relaxation. Another study highlighted that the use of wooden materials positively impacts the human nervous system due to their appealing aesthetics. Seeing or smelling wood in a building boosts positive feelings and reduces negative perceptions of the environment. And this – a positive feeling about the environment – is not a minor thing, says Riina Muilu-Mäkelä, Research Manager and Senior Scientist at the Natural Resources Institute Finland (Luke).
The European Council has formally adopted the Packaging and Packaging Waste Regulation, meaning it will now enter into force in EU law. As the final step in the ordinary legislative procedure, the Council’s approval of the Regulation allows it to be published in the EU’s Official Journal; in turn, its rules will apply eighteen months after its entry into force. It is hoped that the rules will cut down on the generation of new waste by encompassing the full life cycle of packaging. Among the Regulation’s targets are minimum recycled content thresholds, ranging from 10% for contact-sensitive packaging made of non-PET plastic by 2030 to 65% for single-use plastic bottles by 2040. The amount of recycled content in a pack, its material make-up, and other sustainability-related information must be provided to consumers through on-pack labelling, marking, and information. …Reuse targets have also been set for 2030, alongside indicative targets for 2040. 
The European Council has given the green light to the certification framework for carbon removals which includes carbon storage activities that capture & store carbon in long-lasting products for at least 35 years such as wood-based construction products. It is the first EU-level certification framework for permanent carbon removals, carbon farming and carbon storage in products. This voluntary framework will facilitate and encourage high-quality carbon removal and soil emission reduction activities in the EU, as a complement to sustained emission reductions. …Carbon removal activities will have to meet overarching criteria in order to be certified: they must bring about a quantified net carbon removal benefit, they must be additional, they must aim to ensure long-term storage of carbon while minimising the risk of carbon release and do no significant harm to the environment. In addition, activities eligible for certification will need to be independently verified by third-party certification bodies.
