RICS publishes Sustainability Report 2025 on green building market trends
The Royal Institution of Chartered Surveyors (RICS) has published its Sustainability Report 2025, examining market sentiment from over 3,500 global professionals across commercial real estate and construction sectors. The report shows the RICS Sustainable Building Index declined to +30 in 2025 from +41 in 2024, indicating slowing demand growth for green buildings, particularly across the Americas where the index fell to +11. The study found 46% of construction professionals do not measure carbon emissions across projects, representing an increase from 34% in 2024. High initial costs, lack of return on investment evidence, and insufficient investor awareness remain the principal barriers to sustainable building investment. The report recommends government policy measures including mandatory carbon assessment reporting, performance thresholds for emissions, and enhanced building regulations aligned to national decarbonisation pathways. RICS emphasises that measuring and reporting whole life carbon emissions must become standard practice, supported by its professional standard for whole life carbon assessment and the International Cost Management Standard framework.
