Call for applications to join the network

Support provided through the CIN is designed to help climate-positive businesses and projects prepare for finance and engage with potential investors and funders. Participants can access investment readiness support, practical resources and peer learning, with targeted mentoring and opportunities for investor visibility available to businesses and projects further along their journey. 

The delivery of this phase of the initiative is led by Financial Innovation for Impact (Fii) in partnership with the Cambridge Centre for Alternative Finance, Cambridge Judge Business School, with support from the UK Government and the Commonwealth Secretariat. 

Applications are welcome from businesses and projects across Commonwealth countries which: 

• Have a positive climate impact, including established businesses adapting their operations, products or technologies towards climate goals. 
• Are revenue-generating SMEs, development stage or operational projects.
• Plan to raise finance now or in the near future, whether through equity, debt, grants or other forms of funding. 

Successful applicants will gain access to support including: 

• An investment readiness assessment and tailored roadmap. 
• Practical tools and guidance covering areas such as financial modelling, governance, growth strategy and pitch preparation. 
• Opportunities to engage with the CIN community for peer learning and knowledge sharing. 
• Targeted mentorship for businesses and projects further along their investment journey.

About the CIN

The CIN was established to unlock finance for some of the most highly climate-exposed countries, including Small Island Developing States (SIDS). The network is funded by the UK Government, in partnership with the Commonwealth Secretariat, and Financial Innovation for Impact (Fii) alongside the Cambridge Centre for Alternative Finance has been appointed as the delivery partner for its current phase.

The CIN operates as shared Commonwealth investment infrastructure, addressing systemic barriers that limit capital deployment. Its core objective is to build the conditions, capabilities and pipelines required for sustained investment flows, with value created and retained within local economies and institutions. 

Many Commonwealth markets face a two-sided challenge: limited investment‑ready pipelines, and limited funders and investment structures with the expertise to deploy capital locally. These challenges are exacerbated by a lack of mechanisms for cost-effective investment, aligned capital deployment, and durable market infrastructure that can channel diverse sources of finance into smaller, risk-exposed markets at scale. By addressing these barriers, the CIN aims to support the strengthening of economic resilience and enable inclusive economic growth. 

The current phase 

This includes working closely with local partners and continuing to expand the member-led model to deliver long-term impact, deepening and scaling delivery through three concurrent and interconnected pillars of System-Level Change:  

• Bankability and Business Acceleration: Scaled investment readiness support for climate-positive SMEs and projects, building bankable pipelines matched to investor appetite. Establishing a sustainable long-term model through capacity development within Investment Promotion Agencies (IPAs), ministries and local partner organisations to embed capability within local ecosystems. 
• Enabling Environment: Building the institutional conditions and governance mechanisms that underpin robust investment systems and enable private capital to flow. Co-design of investment frameworks, public interventions for real economy impact, sandbox mechanisms, and regulation. The CIN Knowledge Exchange drives shared learning and case study uptake across Commonwealth markets, reducing duplication and accelerating adoption. 
• Investor Solutions: Investor-facing strategic interventions that resolve structural barriers to capital flows at scale, building durable Commonwealth infrastructure and capabilities. 

A cross-cutting approach 

Across all pillars, the CIN is focused on: 

• Building local ownership and capability: Ensuring delivery increasingly sits with local institutions, partners and financial actors.
• Working through partnerships: Engaging governments, IPAs, financial institutions, and regional organisations in co-design and implementation.
• Leveraging the Commonwealth Advantage: Using shared systems and trusted relationships to accelerate learning and reduce costs. 
• Prioritising resilience for climate-vulnerable states: Positioning investable opportunities for growth and resilience.

There is also potential to extend activity into additional markets over time, guided by demand, readiness and partnership opportunities.

Through the Accelerator they have received targeted advice and practical support, growth and investment focused mentorship, access to key stakeholders and potential partners, plus opportunities to pitch to investors.
