The global carbon-negative building materials market is projected to grow from USD 18.8 billion in 2026 to USD 46.9 billion by 2036, according to a new Fact.MR report. The 9.6% CAGR is driven by government Buy Clean programs, stricter embodied carbon regulations, and the commercialization of carbon mineralization technologies in concrete production. Cementitious materials hold the largest share at 32.9%, while residential construction accounts for 32.2% of demand. India is the fastest growing market at 11.4% CAGR, followed by China at 10.7%. Key to this growth is the shift from pilot projects to large scale deployment of carbon negative concrete and engineered biomass products. Developers are increasingly requiring Environmental Product Declarations and third party life cycle assessments during procurement. The report notes that contractors want materials that fit existing workflows while meeting sustainability certifications. The main hurdles remain qualification costs, inconsistent carbon accounting methods, and the capital needed to scale manufacturing capacity across different regulatory environments.
