Sustainability In The Real Estate Industry Statistics

Buildings drive 39% of global CO2, yet the real estate pathway is becoming clearer fast, with net zero retrofits needed for 80% of the stock by 2050 and top green portfolios cutting operational carbon by 10% through performance gains like smart HVAC and better controls. Equally striking, supply chain matters because embodied carbon sits at 11% of global emissions while 90% of a real estate footprint is linked to Scope 3, making this page a practical guide to what changes first, not what looks good on paper.

Buildings are responsible for 39% of global CO2, and the retrofit gap is massive because net zero retrofits are needed for 80% of the stock by 2050. What makes the problem harder is that operational carbon is only half the picture, with embodied carbon sitting at 11% of global emissions and real estate accounting for about 50% of that. The most useful tension is this, the right upgrades can cut operational carbon by 10% in top GRESB portfolios, yet supply chains and materials still carry the heavy load.
