Efficiency policies in buildings and constructions can reduce greenhouse gas emissions by up to 90% in developed countries, and up to 80% in developing countries.
While buildings currently account for 12 Gigatons of GHG globally, their emissions reduction potential amounts to up to 2 Gt (IPCC, 2023). Yet, the sector is still not on track to achieve its full mitigation potential. Today, it accounts for around 37% of energy and process-related CO2 emissions and over 34% of energy demand globally (UNEP, 2022). With 50% of the buildings standing in 2050 yet to be built, urgent shifts in the way we build and use our buildings is crucial (UNEP, 2017).
