Three development banks have committed to mobilising $10 billion in climate investment by 2030, betting that coordinated public capital can pull private money into emerging markets fast enough to matter for the energy transition.

British International Investment (BII), Norfund and FinDev Canada unveiled the initiative — tagged '10by30' — at the COP31 climate summit in Antalya, Türkiye. The number is the whole pitch: $10 billion, privately mobilised, within five years.

How will the $10 billion actually be raised?

The mechanism is straightforward blended finance (public money used to de-risk deals so private investors follow). Each bank will contribute through its existing climate financing platforms: the Norwegian Climate Investment Fund, British Climate Partners, and FinDev Canada's Climate Mobilization Strategy. No new vehicle, no new fund. The partners will:

• Share investment pipelines so deals don't get screened three times over
• Coordinate due diligence (the pre-investment audit of a project's risks and finances)
• Co-invest in major transactions to push deals to a scale single lenders can't reach

The target sectors are renewable energy, grid infrastructure, energy storage, sustainable fuels and industrial decarbonisation. All five sit in the part of the market where emerging economies face the biggest financing shortfalls.

Why now, and why together?

Timing matters. The initiative lands after the COP29 agreement in 2024, which committed developed countries to mobilise at least $300 billion annually for developing countries by 2035, with a wider goal of scaling climate finance from all sources to $1.3 trillion a year. Against numbers that large, $10 billion is a drop. It's a deliberately targeted drop.

Norfund CEO Erik Sandersen framed the efficiency case directly: "Climate finance needs both scale and speed. Working together lets us use our capital and teams more efficiently, so we can move faster and mobilise more private capital where the most emissions can be avoided."

That's the strategic logic in one sentence. Duplication burns time. Shared diligence and co-investment cut it.

What did the executives and ministers say?

The launch drew endorsements from both executives and government figures, which signals political backing as well as institutional commitment.

UK Economic Secretary to the Treasury Lucy Rigby said the partnership demonstrated Britain's commitment to the energy transition in emerging markets. "The UK is backing practical action to unlock investment for the energy transition in emerging markets," she said. Rigby added that mobilising $10 billion in private finance by 2030 would let public funds attract more investment into clean energy, sustainable growth and economic opportunities.

FinDev Canada CEO Lori Kerr pointed to commercial viability as the filter for every deal. Scaling investment in commercially viable climate mitigation projects — particularly in emerging markets with high emissions — was, she said, critical to achieving meaningful climate impact.

"Thanks to our fresh capital, blended finance products, and technical assistance, we are able to attract larger volumes of private capital to make sure investment opportunities have the highest impact on reducing GHG emissions and accelerating the energy transition," Kerr said.

BII CEO Leslie Maasdorp said the initiative was designed to move private capital to areas where climate investment was most urgently needed, and at an unprecedented scale.

Norway's Minister of International Development, Åsmund Aukrust, tied the partnership to the summit itself, calling it a practical contribution to ensuring COP31 delivers concrete outcomes. "The world is running out of time and must speed up the global energy transition to limit the climate crisis," he said.

What are the risks and unknowns?

The banks haven't published a breakdown of how the $10 billion splits among the three institutions, nor interim milestones before 2030. Blended finance has a mixed track record on mobilisation ratios — how many private dollars each public dollar actually attracts — and the partners didn't cite a target ratio.

What is clear is the direction. Three state-backed lenders, three continents of portfolio coverage, one shared pipeline. The test comes at transaction level: whether co-invested deals close faster than the banks' separate efforts would have managed alone.
