Bridging the global climate investment gap estimated at over one trillion dollars annually requires the mobilization of both public and private capital through coherent, transparent, and accountable financial mechanisms. While policy frameworks such as the Paris Agreement and Sustainable Finance Taxonomies have catalyzed green capital flows, the persistent fragmentation between public funding initiatives, private investment vehicles, and carbon accounting standards continues to hinder large-scale climate financing. This paper develops an integrated multi-stakeholder framework for advancing green financing mechanisms that align economic incentives with verifiable environmental outcomes. At the macro level, the study examines policy instruments including green bonds, blended finance, carbon pricing, and sustainability-linked loans highlighting their collective potential to de-risk investments in renewable energy, climate adaptation, and nature-based solutions. It further explores how transparent carbon accounting and assurance standards can serve as the common measurement infrastructure for financial accountability, enabling investors and regulators to evaluate real-world impact with greater precision. The proposed framework positions public institutions as enablers of risk mitigation and regulatory clarity, private investors as drivers of scalable innovation, and third-party verifiers as custodians of ESG data integrity. Using case illustrations from the EU Green Deal, ASEAN sustainable finance initiatives, and African Development Bank climate facilities, the paper identifies pathways for harmonizing disclosure standards, improving credit enhancement mechanisms, and linking capital allocation directly to verified emissions reductions. The research concludes that bridging the climate finance gap depends on institutionalized transparency, cross-sector collaboration, and the integration of carbon metrics into financial decision-making.
