The United Nations Environment Programme has released the 10th edition of the “Global Status Report for Buildings and Construction 2025–2026”.
The sector remains off track to achieve net-zero emissions by 2050.
The buildings and construction sector accounts for 37% of global carbon emissions and nearly 50% of global material extraction.
Buildings’ operational emissions increased to 9.9 gigatonnes of carbon dioxide (GtCO₂) in 2024 and must decline by 56% by 2030 to meet climate targets.
Cement, steel, and aluminium used in buildings contributed around 9% of global emissions in 2024 due to embodied carbon emissions.
Global building floor area increased by 1.7% in 2024 to 273 billion square metres, with major growth seen in India and Southeast Asia.
