Commercial real estate assets with green certification demonstrated a commanding performance throughout 2025, yielding gross revenues per square metre that surpassed their non-certified counterparts by a substantial 34%.
Green-certified prime and A-grade offices have outperformed comparable non-certified offices by a cumulative 28.2%, providing compelling evidence of the long-term investment value associated with sustainable real estate.
Published annually since 2016 by MSCI in collaboration with the Green Building Council South Africa (GBCSA) and sponsored by Growthpoint Properties (JSE: GRT), the 2025 MSCI Green Annual Property Index provides an independent, globally aligned assessment of how green-certified properties perform relative to their non-certified counterparts.
South Africa’s MSCI Green Annual Property Index shows that, based on performance to December 2025, green-certified prime and A-grade offices delivered an annualised total return of 6.98% over the past decade, compared with 5.26% for non-certified office assets.
This 172-basis-point annualised advantage has accumulated steadily over time, resulting in the substantial return premium now reflected in the data.
