Between now and 2050, the world’s population will increase by 2 billion people to over 9.5 billion and the share of the population living in cities will increase by 10 percentage points to 68%. These demographic megatrends will continue to underpin the buildings and infrastructure sector and steel demand.
Given these megatrends and the support this will require from construction, it is essential to keep in mind that today the operation of buildings accounts for 28% of global CO2 emission..
These emissions must be significantly reduced as buildings become net zero operational carbon by 2050.
Steel’s role is at the core of the transition to net zero energy buildings.
Here are four reasons why steel has its place in the transition toward net zero:
constructsteel – worldsteel’s steel construction market development programme aims to disseminate these benefits and engage with stakeholders in the construction industry. POSCO’s INNOVILT and ArcelorMittal’s Steligence construction programmes are two good examples of how our members are spreading the positive message across to our stakeholders.
We are confident that steel has a role to play in making buildings net zero operational carbon by 2050. Please consult constructsteel.org for regular updates of constructsteel. I look forward to your comments.
 Buildings are currently responsible for 39% of global energy related carbon emissions: 28% from operational emissions, from energy needed to heat, cool and power them, and the remaining 11% from materials and construction. (https://www.worldgbc.org/embodied-carbon)
