construction with
steel structures
Source: Tsinghua School of Civil Engineering, 2021. Green construction with steel structures includes the shift to green concrete and green steel
in addition to the move from current reinforced concrete structures to steel structures.
Building construction is
responsible for about 30% of
China's carbon emissions
New China building code will
require higher seismic
precautionary intensity
A shift to green construction
and steel structures will reduce
carbon emissions by ~60%
Moving to steel structures
contributes up to a third of the
total emissions reduction
Steel intensity of construction
increases by ~45-80% across
low to high rise buildings
