Deepki has published the 2026 Deepki Index, the only publicly available transatlantic benchmark of the real estate industry’s environmental performance, using real consumption data. Now in its fifth year, the index tracks the evolution of the European building stock’s energy consumption and carbon emissions across six major markets, as well as covering six regions and three building typologies in the United States.
Since 2021, the Deepki Index has tracked the real energy consumption of tens of thousands of European buildings. Average final energy consumption across all typologies rose from 156 kilowatt-hours per square meter in 2021 to 165 kilowatt-hours per square meter in 2025, a net increase of 5 percent over five years, despite the introduction of the E.U. Taxonomy, the Sustainable Finance Disclosure Regulation and the Corporate Sustainability Reporting Directive during the same period.
