The growth of the mass timber construction industry in Canada is being slowed by persistent high insurance rates on wood-frame buildings that are six to 10 times higher than those for conventional steel and concrete structures. That is the conclusion of the Climate Smart Buildings Alliance (CSBA), which is actively working to convince insurers to revise their pricing policies toward mass timber buildings that carry a low carbon footprint. CSBA director David Messer said, “Mass timber buildings are new on the construction landscape and the lack of data complicates the task of insurance companies in assessing actuarial risk and deciding how risky mass timber buildings are to insure.” …In May the CSBA teamed up with the Canadian Wood Council and assembled 40 leading insurance and building industry executives to launch the Mass Timber Insurance Action Plan to provide a comprehensive framework for risk data collection, assessment and evaluation.
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.
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.
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.
