Embodied carbon will be responsible for almost half of total new construction emissions between now
and 2050.
Source: Architecture 2030, in Carbon Leadership Forum, Advancing Low Carbon Construction through research, education and outreach. (2017)
Limiting global temperature change to 1.5°C
2030: CO2 emissions decline by 45% from 2010 levels
2050: Net zero emissions
Embodied carbon will be responsible for almost half of total new construction emissions between now
and 2050.
“All pathways that limit global warming to 1.5°C with limited or no overshoot project the use of carbon dioxide removal (CDR). . . over the 21st century.”

Construction
“The possibility before us is not just to do less bad, but to do ecologically good things and move towards regenerative buildings and cities that act like forests to clean the air and water, and absorb atmospheric carbon. . . . transforming the built environment into a massive carbon sink.”
