This article examines the specific mechanisms by which capital is mobilized for green building initiatives. Against a backdrop of intensifying institutional pressure, an expanding climate agenda and the reallocation of global investment flows, this topic has taken on heightened importance. Yet, despite surging interest in sustainable development projects, the financial mobilization instruments in this sector remain fragmented, weakly institutionalized and poorly harmonized with existing regulations. The study’s aim is to identify the array of active financial tools and to assess the barriers that hinder the flow of sustainable investment into environmentally focused construction. A review of current literature reveals a persistent disconnect between declared sustainable-development policies and the actual structure of investment decision-making—particularly between macro-level strategies and on-the-ground regulatory practices. The analysis demonstrates that the prevailing approach within the financial-institutional environment is project-specific and discrete, while systemic mechanisms—such as coordinated institutional frameworks, risk-standardization protocols and the integration of environmental requirements into mainstream credit and banking practices—remain underdeveloped. The author’s contribution lies in an interdisciplinary systematization of financing sources and a taxonomy of the constraints involved. These findings will inform researchers in environmental finance, urban studies and public policy, as well as practitioners—investors, developers and regulators—seeking to foster more coherent, scalable investment in green construction.
