The Trillions Tracker
Transitioning our energy systems, combatting the impacts of climate change, and supporting people to lift themselves out of poverty are the great challenges of our time. We can tackle them, but it costs money.
Governments have made progress on an additional US$700 billion per year over the past few years on these priorities, but a US$1.75 trillion annual spending gap remains in official finance.
Progress towards the public spending gap

“Domestic” refers to Domestic Resource Mobilisation, “Aid” refers to Official Development Assistance, “Multilateral” refers to Multilateral non-concessional, and “Bilateral” refers to Bilateral non-concessional + Innovative finance.
The full story
In 2022, independent experts estimated( 1 ) a US$2.5 trillion annual public spending gap to fund the energy transition, prepare for and protect people from climate change, and fund development needs like education and healthcare in low- and middle-income countries.( 2 )
According to their scenario, the governments of these countries are expected to fill roughly US$2 trillion of the gap using domestic resources. The international community – G20 governments, multilateral development banks, and the IMF – would fill the remaining US$500 billion using international public finance.
How close have we gotten to these targets?
Annual public spending (and planned spending)( 3 ) on climate and development increased by roughly US$700 billion over the last few years – 29% of what’s needed to fill the financing gap. That leaves a gap of nearly US$1.75 trillion.
Let’s break that down:( 4 )
- Domestic resources from low- and middle-income countries (excluding China) increased by US$416 billion each year between 2019 and 2022; that helped cover 21% of the domestic financing gap.
- International public finance flows (including potential commitments) have increased by US$285 billion between 2019 and 2022; that helped cover 57% of the international financing gap.
How should external public finance be increased?( 5 )
- An additional US$180 billion in official development assistance (ODA) by 2030 from G20 governments and other advanced economies. That would be almost double the US$192 billion in ODA provided in 2019. By 2023, ODA had increased by US$73.3 billion (41% towards closing the gap), but US$31 billion was spent at home on in-country refugee costs. So in real terms, they have closed 24% of the target.
- An additional US$250 billion per year is needed from multilateral non-concessional lending. This increased by US$21.5 billion between 2019 and 2022. The major multilateral development banks (MDBs) have reported that recent reforms will unlock an additional US$357 billion in MDB lending headroom over the next decade (that’s potentially $186 billion in planned spending by 2030)( 6 ). Although additional lending headroom is not guaranteed to translate completely to new lending, the combined potential increase in multilateral non-concessional lending plus new headroom could total US$207 billion in new non-concessional lending per year — 83% towards the US$250 billion target.
- An additional US$70 billion per year should come from bilateral non-concessional lending and innovative finance. But since 2019, bilateral non-concessional lending has decreased by US$4.1 billion. In terms of innovative finance, G20 governments and other advanced economies’ commitments to recycle US$100 billion of Special Drawing Rights to low- and middle-income countries could yield on average US$8.3 billion in additional lending per year via IMF trust funds.( 7 ) That would yield total additional financing of US$4.2 billion, just 6% towards the target.
We should celebrate progress in closing the finance gap.
But we have a long way to go.
How to Close the Gap
