Solution Areas
The 2026 GCBC Accelerator is looking for organizations that have practical, scalable solutions that can help emerging and developing economies design and implement effective country platforms.
We are especially interested in organizations that bring hands-on experience, strong local or regional knowledge, and tools or advisory models that can help emerging markets and developing economies move from ambition to investable action.
Strengthening enabling environments
Solutions that help EMDE governments and institutions build the institutional foundations for country platforms, including governance design, stakeholder management, cross-ministerial collaboration, and tools to assess and identify flow of capital.
Improving planning
Solutions that help EMDE governments and institutions translate long-term climate and development goals into near-term, investable strategies, including sectoral modelling, policy roadmaps, readiness assessments, and project pipeline development.
Overcoming financing hurdles
Solutions that help EMDEs access appropriate catalytic capital and mobilize private investment, including financial modeling, business case articulation, and early engagement with DFIs, donors, and private investors.
Supporting Implementation
Solutions that help move country priorities from pipeline to delivery, including project preparation, transaction advisory, investment readiness support, and capacity building for local government stakeholders.

Eligibility Criteria
The 2026 GCBC Accelerator is open to organizations, partnerships, and specific programs working on capacity building across emerging markets and developing economies (EMDEs). Applicants should be based in or have a very strong presence in EMDEs.
Applicants do not need to be working on a live country platform or program today to apply. If your work is relevant to how country platforms are designed, financed, or delivered, we want to hear from you.
This includes efforts linked to pipeline preparation facilities, transaction advisory services, technical advisory to governments and other enabling environment work that facilitates the flow of capital.
Note: GCBC members are eligible to apply. Founding and Observer Members may not apply individually, but are eligible to apply as part of partnerships.
Judging Criteria
Country Platform Fit
Does the applicant demonstrate a strong understanding of one or more key country platform bottlenecks that hinder mobilization of capital in EMDEs, and is either already supporting related activities or has clear potential and ambition to contribute meaningfully to development?
Demand-Driven Design
Is the work shaped by, and responsive to, what end-users actually need in terms of capacity building?
Track Record and Technical Expertise
Does the organization have the track record and technical expertise in sustainable finance capacity?
Finance Mobilization and Lasting Impact
Does this work mobilize sustainable finance and deliver change that outlasts the engagement?
Readiness for GCBC Support
Can this organization absorb, deploy, and amplify GCBC support modalities – particularly co-design of capacity building?
