The COP31 climate finance agenda took shape in Istanbul on 4 September 2026, when the summit’s presidency used the Istanbul Climate Finance Summit to lay out how money — not just promises — will move countries toward the goals set for the Antalya summit. COP31 President-Designate Murat Kurum told delegates that the world faces a “chasm” between the climate investment it needs and the money it actually spends, and announced that the UN Development Programme (UNDP) will help run the presidency’s flagship Climate Implementation Bridge (BRIDGE) initiative.
Key Facts
- What happened: The Istanbul Climate Finance Summit (ICFS) on 4 September 2026 brought together banks, development finance institutions, multilateral climate funds and governments to set the finance track on the road to COP31.
- The finance gap: Climate investment needs stand at $7.5–9 trillion, while the world currently invests only about $1.9 trillion, according to COP31 President-Designate Murat Kurum.
- BRIDGE: UNDP was named delivery partner for the Climate Implementation Bridge, a flagship COP31 Presidency initiative that turns national climate and development priorities into finance-ready project portfolios.
- The declaration: The Istanbul Declaration on Climate Implementation and Finance was signed by multilateral development banks, climate funds, governments, city networks and private investors.
- The target: Electricity should meet 35% of global final energy consumption by 2035 — the presidency’s “35-by-35” electrification goal.
- Next stop: COP31 takes place in Antalya, Türkiye, from 9 to 20 November 2026.
Closing the COP31 climate finance gap
Kurum framed climate finance as a matter of global security. With NATO countries expected to lift defence-related investment to as much as 5% of GDP, he said climate investment deserved “ambition on a similar scale” and should be viewed “through precisely the same strategic lens”.
“The question could not be clearer: if we no longer have a safe world to live in, what purpose will all our spending to defend our countries serve?” he told the summit.
His central demand was for leaders to stop treating climate finance as a cost. In his words, it is “a strategic investment made today to avert far greater economic and social losses tomorrow” — and he urged world leaders to commit greater resources to clean energy, electrification, resilient cities and green industry.
BRIDGE and the Istanbul Declaration
The summit’s biggest practical outcome was the move of the Climate Implementation Bridge toward full operation. The initiative is designed to close the gap between climate ambition and capital deployment by offering country-driven implementation support, so governments can convert their climate and development priorities into portfolios of finance-ready projects.
With UNDP confirmed as delivery partner, BRIDGE will draw on the UN system’s established delivery infrastructure to reach countries quickly. The initiative’s operationalization is one of the COP31 Presidency’s central promises, and the summit saw it take a decisive step forward.
In the afternoon session, the presidency unveiled the Istanbul Declaration on Climate Implementation and Finance. Its signatories span the full financing chain: multilateral development banks, development finance institutions, multilateral climate funds, international organizations, UN entities, national and local governments, city networks, private sector representatives, institutional investors, commercial financial institutions and philanthropic organizations.
The declaration welcomes BRIDGE, acknowledges the 35-by-35 electrification target and commits signatories to greater collaboration — from technical support and urban financing facilities to better-coordinated capital mobilization through regional and international financial centers.
The numbers behind the call
Kurum’s case rests on a simple comparison: what the transition needs, and what is actually being spent.
| Measure | Where the world stands | Where it needs to go |
|---|---|---|
| Annual climate finance | About $1.9 trillion invested | $7.5–9 trillion needed |
| Electricity’s share of final energy demand | About 20% today | 35% by 2035 (“35-by-35”) |
From dialogue to investable projects
On the margins of the same week, a “Towards COP31: Climate Finance Policy Dialogue” at the Istanbul Financial Center explored how to turn ambition into investable action. Convened by the Ministry of Treasury and Finance, the UN in Türkiye and the COP31 Climate High-Level Champion’s office, it drew in senior figures including Treasury and Finance Minister Mehmet Şimşek, UNDP’s Marcos Neto and International Energy Agency Executive Director Fatih Birol.
The dialogue closed with a Partnership Protocols Signing Ceremony — financial agreements between the Ministry of Treasury and Finance, the World Bank and Turkish development banks — and a Declaration of Intent on climate and development finance between the ministry and the UN in Türkiye, covering areas from project preparation to innovative financing.
The message from both gatherings was the same: planning is over, delivery is next. As Neto put it during the policy dialogue, “the world does not need more planning or more pledges” — what it needs is delivery and implementation.
What happens next
The Istanbul Declaration will now feed into COP31’s finance discussions in Antalya, where negotiators are expected to vote on a presidency-led decision including an electrification component. Recommendations from the Istanbul dialogue will also be passed to the COP31 Presidency, the High-Level Champion’s office and international financial institutions.
Whether the “chasm” closes depends on whether the institutions that signed the declaration turn their commitments into funded projects. BRIDGE, with UNDP as delivery partner, is the presidency’s chosen vehicle for exactly that test.
