Embodied Carbon: The Hidden Cost of Construction
Understanding the carbon emissions embedded in building materials and infrastructure

Section 1 of 5What is Embodied Carbon?
Embodied carbon refers to the greenhouse gas emissions associated with the production, transportation, and construction of building materials and infrastructure. Unlike operational carbon (ongoing energy use), embodied carbon is "locked in" at the time of construction and represents up to 50% of a building's total lifetime carbon emissions.
Every material we use - from concrete and steel to glass and insulation - has a carbon cost. This includes extracting raw materials, manufacturing processes, transportation, and assembly. Understanding and reducing embodied carbon is crucial for achieving net-zero construction and meeting climate goals.
The Scale of the Problem
Global construction accounts for 39% of all carbon emissions. Of this, embodied carbon represents about 11 Gt CO₂e annually - more than aviation and shipping combined. With urbanization accelerating worldwide, this number is only expected to grow.
