Climate Finance Explained: Who Pays, Who Gets, and Is It Working? (2025)

Climate finance: It's a critical lifeline for a planet in crisis, but understanding where the money comes from, where it goes, and how it's used can be a complex puzzle. Let's break it down. Sixteen years ago, at the Copenhagen climate summit, wealthy nations, the biggest contributors to pollution, committed to providing $100 billion (approximately £76 billion) annually by 2020. The goal? To help less affluent countries cut emissions and adapt to the effects of a warming world. Fast forward to today, and a new target has been set: $300 billion (around £227 billion) each year by 2035.

But here's where it gets controversial... Defining and tracking what truly qualifies as 'climate finance' has been a challenge. Some experts even call it a 'wild west' due to vague definitions, questionable projects, and inflated accounting practices.

According to the Organisation for Economic Co-operation and Development (OECD), developed nations missed their initial deadline but eventually met the $100 billion goal in 2022, providing $116 billion (about £88 billion). However, Oxfam, a charity that also monitors this funding but takes a more critical stance on how loans are counted, estimates the actual amount to be closer to $95.3 billion (roughly £72 billion) that year. They believe the grant-equivalent value was less than $35 billion (around £26.5 billion).

So, where does this money originate?

The majority of climate finance comes from public sources, accounting for over three-quarters of the funding that developing countries receive for climate projects. This public funding is distributed in two main ways: directly to recipients as bilateral funding and through multilateral institutions like the World Bank.

In addition to government funds, donor countries (including 23 developed nations and the EU) also count other sources, such as export credits and private capital mobilized due to their investments.

Who benefits from this climate finance?

Official UN data lacks the transparency to fully track all financial flows. However, an analysis by The Guardian and Carbon Brief suggests that about one-fifth of the public funding in 2022 went to the 44 poorest nations globally. This group includes countries highly vulnerable to climate change, such as Tuvalu, Chad, Madagascar, and Yemen.

A larger portion of the funds goes to developing countries, a broader group that includes lower-middle-income countries like India and upper-middle-income countries like China. Interestingly, even some oil-rich nations, such as Saudi Arabia and the UAE, are recipients of climate finance.

And who are the main contributors?

Japan, Germany, the US, and France provide two-thirds of the public funding. The US's increased bilateral funding in 2021, under the Biden administration, helped meet the 2022 target. Another key factor was increased private investments mobilized by developed nations.

However, political shifts can impact this. For example, under the Trump administration, the USAID agency was shut down, and there were threats to reduce contributions from the world’s biggest historical polluter of greenhouse gases. Several other wealthy donors have also cut their aid budgets.

Is this money given as grants or loans?

It's not all grants. Two-thirds of the climate finance to developing countries comes in the form of loans. This reliance on debt has been criticized for increasing pressure on already vulnerable countries, forcing them to spend more on interest payments. Some loans even have conditions requiring recipients to hire companies from the donor country.

What are the loan terms like?

Some loans are offered at more favorable terms than those available on the market. These are known as concessional loans, which can help poorer countries fund projects like public transport or solar farms without the burden of standard interest rates. However, the majority of loans in 2022 were offered under non-concessional terms.

What's the new target?

The $100 billion annual target, set to run until 2025, is being replaced with a new goal for developed countries to provide $300 billion each year by 2035.

This new annual target – known as the “new collective quantified goal” – also includes a broader aim of mobilizing $1.3 trillion (£1 trillion) each year by 2035.

While this figure is closer to the actual needs of developing countries, only $300 billion is expected to come from the budgets of developed countries and institutions like the World Bank. The remaining funds are intended to come from private sector investments.

Analysts have expressed concerns that such funding is even less transparent and accountable than public finance, though they acknowledge that it may be difficult for poorer countries to persuade rich ones to provide such large sums of money.

What's next?

Climate finance is again expected to be a key topic at the annual UN climate negotiations, known as Cop.

The Cop presidencies of Azerbaijan and Brazil published a report exploring ways to raise funds through new taxes on the wealthy, fossil fuels, financial transactions, and polluting activities. The Baku to Belém Roadmap also suggests swapping outstanding debt for climate action as a way to provide debt relief for cash-strapped governments.

The new target is seen as an opportunity to restore credibility around climate finance and avoid being labeled a 'wild west' due to a lack of transparency and inconsistencies in reporting.
