British International Investment (BII), the UK’s development finance institution and impact investor, has committed US$60 million to the Green Investment Partnership (GIP), managed by Pentagreen Capital, to support green and sustainable infrastructure across South-East Asia.
South-East Asia is estimated to require about US$210 billion a year for climate‑resilient infrastructure—an investment need public finance cannot meet alone. To help close this gap, the Financing Asia’s Transition Partnership (FAST‑P), launched by the Monetary Authority of Singapore (MAS) in 2023, created GIP to finance and de‑risk climate projects in the region.
GIP is a blended‑finance vehicle under FAST‑P with US$510 million in committed capital at first close in early September 2025 from global and regional private, public and philanthropic institutions. It will back projects in sectors critical to decarbonisation and growth, including renewable energy, distributed generation, e‑mobility, circular economy and emerging climate solutions.
GIP begins investing this year, starting with a bio‑energy programme through BECIS Bioenergy that converts agricultural waste and other sustainably sourced feedstock into renewable steam, avoiding over 100,000 tonnes of emissions a year (estimated). A renewables portfolio with ib vogt will add utility‑scale solar and battery storage projects, cutting an estimated 257,000 tonnes of emissions annually.
BII’s US$60 million commitment, including US$10 million from its £100 million mobilisation facility announced by the UK Prime Minister at the UN General Assembly in 2024, helped the vehicle reach first close by strengthening the capital structure to attract further commercial investment.
Leslie Maasdorp, Chief Executive of BII, said: “We are proud to support GIP, which shows how blended finance can bring public, private and development capital together to unlock projects that might otherwise stall. Our participation is designed to catalyse further commercial investment and scale climate action across the region.”
British High Commissioner to Singapore, Nikesh Mehta, said: “The UK’s commitment to the Green Investment Partnership reflects our determination to mobilise private capital for climate action at scale in South‑East Asia. Co‑investing alongside Singapore and other partners through FAST‑P will unlock investment for clean energy and sustainable infrastructure, supporting growth and jobs.”
This investment underscores BII’s strategy to provide and mobilise climate finance at scale, crowding in commercial capital to deliver practical, measurable impact across the region.
