The Commonwealth Investment Network (CIN) is focused on identifying and facilitating the scale up of climate-related investment opportunities by fostering collaboration, enhancing bankability and driving system-level change. Launched at the Commonwealth Heads of Government Meeting (CHOGM) in October 2024, the CIN is designed to foster collaboration among local, regional, and international partners, by identifying and supporting investment opportunities in SIDS. It forms a key part of the Commonwealth Secretariat and His Majesty’s Government’s strategy for stronger trade and investment in the Commonwealth.
Now in its implementation phase, the CIN is piloting a set of interventions across Caribbean and Pacific Commonwealth SIDS, laying the foundations for future scale. It aims to deliver increased investment viability of climate-positive projects in SIDS, strengthen institutional ecosystems which enhance climate project bankability and spotlight opportunities across SIDS, delivered through knowledge exchange, capacity building and technical assistance, in collaboration with partners and experts. It is a key mechanism for the delivery of the Commonwealth Plan of Action on Investment and the Commonwealth Secretariat Strategic Plan 2025 - 2030, the goal of which is to boost trade and investment and build economic resilience across the Commonwealth.
The network is funded by the UK Government, in partnership with the Commonwealth Secretariat, and delivered by the Cambridge Centre for Alternative Finance, Cambridge Judge Business School.
It comprises three key pillars of intervention:
Knowledge Exchange
A central online platform has been launched to facilitate knowledge sharing among stakeholders, to help break down siloed approaches to project delivery and investment and increase sharing of best practice. The CIN KE enables real-time responses to challenges faced by stakeholders and provides a repository of ‘always available’ resources and insights, including for investment readiness and project support.
Project Preparation & Acceleration
A programme and capability designed to enhance bankability of projects and businesses and scale up the volume of bankable pipeline projects and growth-stage SMEs. In autumn 2025, climate-positive businesses and projects were invited to apply for the Commonwealth Investment Network (CIN) Accelerator, of which 7 were selected by an independent judging panel as members of the inaugural cohort.
Each of these businesses was selected for their potential to scale, commercial viability, and climate mitigation, adaptation, or resilience impact. 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.
- Belmont Estate: an organic agribusiness in Grenada that has evolved from a traditional farm into one of the country’s leading agri-tourism and sustainable development enterprises.
- BildBeta: a Vanuatu-based engineering and project-management firm led by engineers, who develop humanitarian and cooperation projects which help Pacific communities reduce disaster risk and adapt to climate change.
- Eagle Vetiver Systems: pioneers sustainable land restoration in Papua New Guinea, cultivating vetiver grass - a resilient plant with deep roots that prevent soil erosion - to rehabilitate degraded land and capture carbon.
- Green Feeds: based in Grenada, revolutionises agriculture and waste management by transforming bio-waste into sustainable animal feed, fertiliser, and renewable energy.
- OraSoil: transforms organic ‘waste’ in Fiji, such as coconut husks and agricultural by-products, into high-value, market-ready products, using solar-powered mobile processing units integrated with community solar mini-grids.
- RecycleCorp: a leading recycling business in Vanuatu, which reduces the island's waste and feeds recyclables back into global markets, lowering Vanuatu’s climate footprint.
- SarGas: a Grenadian climate-tech company, converts invasive Sargassum seaweed and other organic waste into renewable biogas and organic fertiliser, enabling the sustainable transformation of small island energy, agricultural, and waste management systems.
System-level Change
The current phase of the CIN has prioritised testing a set of interventions to assess where the network can deliver maximum depth and scale of impact, complementing and partnering with existing initiatives and local stakeholders. For example, the CIN is working alongside Investment Promotion Agencies, to understand their priorities as a key part of the project preparation ecosystem, and provide support through capacity building and amplification of their work.
Looking ahead, there are significant opportunities to drive system-level change by pursuing strategic initiatives which address market-wide barriers to capital flows. These opportunities have been surfaced, tested and distilled down through workshops with private and public stakeholders from across the Commonwealth. They represent solvable challenges with significant capital mobilisation potential. The CIN's Expert Advisory Board has supported the development of these, which include the physical and digital aggregation of projects and data, and fairly pricing and insuring against climate risk.

Background
The CIN was launched at the 2024 Commonwealth Heads of Government Meeting in Samoa to support the development of bankable projects and promote climate-positive growth opportunities. The network is funded by the UK Government, in partnership with the Commonwealth Secretariat, and the Cambridge Centre for Alternative Finance has been appointed as the delivery partner for its current phase running to March 2026.
