Climate change is an urgent challenge already facing the countries where we invest. We invest our own capital, as well as aim to mobilise private capital, to reduce greenhouse gas emissions, transform economies to be cleaner and greener, protect the environment and increase climate resilience.

We achieve positive impact across three areas

Accelerating green growth

Climate change is already reshaping economies, livelihoods and development prospects across the countries where we invest. Its impacts fall hardest on those least responsible for emissions – increasing pressure on energy systems, food production, infrastructure and jobs.

In response, we continue to step up our climate finance leadership. We’re proud to be one of the UK Government’s largest providers of climate finance to emerging and developing economies. In the knowledge that our capital alone is not enough, we’re also focused on mobilising the private investment that’s critical to tackling climate change.

Over the year, our climate finance investments focused on removing some of the biggest barriers to the net-zero and resilient transition in emerging economies. This included financing groundbreaking battery storage and renewable energy projects, helping stabilise power systems and unlock greater use of clean electricity at scale.

We also expanded our support for e‑mobility, backing cleaner transport solutions that cut emissions while improving affordability and reliability for workers and small businesses.

Alongside this, we worked with financial partners to help companies shift away from high‑emissions processes and invest in more efficient, sustainable ways of operating.

And across our portfolio, we’ve increased the climate resilience of our investments, while also investing in businesses that are strengthening climate resilience for vulnerable communities and sectors.

Together, these investments support faster decarbonisation while strengthening energy security, productivity and resilience across economies.

Increasing investment in climate finance

In 2025, we committed £827 million to climate finance, representing 45 per cent of our total commitments (see chart). Across the 2022–26 Strategy period, the average was 43 per cent. This exceeds our target to make 30 per cent of our investments in climate finance over the strategy period. Our climate finance commitments mobilised $774 million in private investment.

At the same time, climate‑finance‑qualifying assets continue to make up a growing share of our overall portfolio. They accounted for £1.97 billion or 29.4 per cent of our overall portfolio as at year-end 2025. This represents a 2.9 per cent year-on-year increase in share of portfolio by value and a 12.5 per cent increase since the beginning of the 2022–26 Strategy period.

These metrics are one part of how we track progress. Our reporting against the UK Government’s Climate‑related Financial Disclosure regulations sets out our approach to governance, strategy, risk management, metrics and targets for managing climate‑related risks and opportunities across our portfolio and operations. This is published in our Annual Report and Accounts.

We know that addressing the climate emergency requires significant private investment, and 2025 has seen an increased focus on this area. We announced the first winner of our mobilisation competition, which saw BII partner with BlueOrchard, as an anchor investor in a new fund specifically designed to unlock insurance capital to combat the climate emergency in emerging markets. Outside of the competition, we advanced mobilisation through blended finance, backing a range of investments designed to crowd in private capital. This included our anchor investment in the Allianz Credit Emerging Markets (ACE) fund, which mobilised $540 million from commercial investors at first close.

We also deepened our partnership with Pentagreen through a commitment to the Green Investment Partnership, a blended finance vehicle within the Financing Asia’s Transition Partnership (FAST-P). Our commitment is helping to de-risk the fund’s capital structure and crowd in additional private investment.
