The building industry is a significant contributor to climate change. Buildings and construction are currently responsible for 39% of all global greenhouse gas (GHG) emissions (UNE 2017). Since cities are only expected to grow in the coming decades, reducing emissions from the building sector is critical to addressing climate change. As new policies and technologies reduce buildings’ operational energy and emissions, the embodied energy and emissions from building materials choices are becoming proportionally more significant.
Making More Sustainable Material Choices
In alignment with our climate action priorities, UBC is working to advance our understanding of the environmental impacts of materials throughout a building’s full life cycle: resource extraction, production, installation, use, and end-of-life reuse or disposal.
We are developing policies and guidelines to help building designers make material choices that reduce negative environmental impacts, including reducing GHG emissions. We are supporting research to measure and assess the environmental impacts of materials, and working with partners at the local and federal level, to incorporate that information into new projects. Many of our researchers are also involved in the development of new types of sustainable materials and cleaner production processes that can improve Canada’s manufacturing and supply chains.
Through Campus as a Living Lab, UBC is exploring opportunities to pilot the use of low-carbon materials, and ways to measure the impacts, improving the quality of the campus buildings.
