"Buildings are one of our biggest contributors to global heating. They produce
37% of all greenhouse gas emissions from energy use and production processes.
Building emissions are made up of two parts: operational carbon (from energy
used to heat, cool and power buildings) and embodied carbon (due to material
use and construction).
We know how to reduce operational carbon to net zero by increasing insulation
and air-tightness, and by using renewable energy. It’s entirely unclear how
we’ll get down to net-zero embodied carbon.
Embodied carbon amounts to about half a new building’s lifetime emissions, so
it’s essential to reduce it. As operational carbon emissions are cut, embodied
carbon’s share of building emissions could rise to 85% by 2050. So vexed is
this problem that some have called for a general “halt to new construction” in
the developed world.
Our new research shows while we can greatly reduce embodied carbon in
Australia, it will require radical changes in how we design, construct, use and
reuse buildings."
