Architects are realizing the 2030 Challenge is no longer just about
tracking predicted Energy
Use Intensity (pEUI) and operational
carbon (the carbon emitted from building mechanical systems). In the next 10
years, it will be critical to also make great strides in reducing embodied
carbon (the carbon emitted from the interior and exterior materials that are
used to construct buildings). Embodied carbon emissions make up a large amount
of greenhouse emissions from the built environment and have greater potential
to have an immediate impact on reducing the effects of climate change. Overall,
building energy sources and their materials account for nearly 40% of all global
emissions. However, over the next 10 years, approximately 72% of the carbon
emitted from new construction will be from embodied carbon. Those metrics alone
make it undeniable that as designers, we have a role and responsibility to
mitigate environmental impacts by working with nature to develop
resilient, sustainable, low carbon projects.
