Understanding Embodied Carbon in Buildings
Embodied carbon refers to the total greenhouse gas emissions associated with the production, transportation, and installation of building materials throughout their lifecycle. As we strive to reduce our carbon footprint in the AEC industry, understanding embodied carbon is crucial. It accounts for a significant portion of a building’s overall carbon emissions, often surpassing operational emissions in the case of certain materials.
By focusing on embodied carbon, we can make informed decisions that lead to more sustainable building practices.
Trees absorb carbon dioxide from the atmosphere as they grow, effectively sequestering carbon within their biomass.
When we use timber in construction, we are not only utilizing a renewable resource but also locking away that carbon for the lifespan of the building. This understanding of embodied carbon positions mass timber as a key player in our efforts to combat climate change and promote sustainable development.
