COP31 Climate Finance Explained: From $300 Billion to $1.3 Trillion

Why climate finance dominates COP31

UN News reported on the summit's opening day that finance remains a sticking point, with developing countries pressing for faster access to climate finance while clean energy, adaptation and a just transition top the agenda. Many of the countries most exposed to climate change contributed least to causing it — and face the highest cost of capital to respond.

The numbers: $300 billion and $1.3 trillion

At COP29 in Baku, developed countries agreed a new collective goal: $300 billion per year in climate finance for developing countries by 2035. Developing nations had asked for far more, so a wider Baku-to-Belém Roadmap was formalised before COP30, aiming to mobilise $1.3 trillion a year from both public and private sources by 2035.

The gap between those two figures — roughly $1 trillion a year — is where the real debate lies: how much must be public money, and how much can private investment realistically deliver?

The Article 9 debate

COP30 set up a two-year work programme on climate finance, including discussions on Article 9.1 of the Paris Agreement, which says developed countries 'shall provide' financial resources to developing countries. At the June 2026 Bonn talks, there was little progress. Developing countries want the programme focused on that obligation; developed countries want to discuss Article 9 as a whole, including private finance and other sources.

At COP31, negotiators must decide how to reach the agreed targets — and what role private finance will play.

Adaptation finance: tripling by 2035

At COP30, countries agreed to triple adaptation finance by 2035 and adopted 59 indicators for the Global Goal on Adaptation. But talks stalled in Bonn: developing nations want $120 billion a year for adaptation by 2030, while developed nations have resisted a specific number. That fight returns to Antalya.

Carbon markets under Article 6

Article 6 of the Paris Agreement lets countries trade carbon credits to help meet their targets. After years of rule-making, the focus at COP31 is on making the mechanisms work in practice — including how to fund the infrastructure, processes and capacity-building for Article 6.2 cooperative approaches, and moving eligible projects over from the old Clean Development Mechanism. A new methodology for cutting emissions from nitric acid production was adopted in Bonn.

For project developers, well-functioning carbon markets can add a valuable revenue stream to renewable energy, reforestation and clean water projects.

Where private capital fits in

Public money alone will never reach $1.3 trillion. The biggest lever is unlocking private investment, which requires:

• Bankable project pipelines with clear revenue models.
• Risk-sharing tools such as guarantees and blended finance from development banks.
• Government partnerships that provide policy certainty and land, permits and offtake.
• Transparent impact measurement so investors can verify results.

What it means for investors and governments

Sovereign wealth funds, institutional investors and family offices are increasingly looking for climate infrastructure exposure — but struggle to find investment-ready opportunities in high-growth markets. Governments, meanwhile, need partners who can move from memorandum to megawatts.

EnerSynk's platform is built for exactly that connection: bringing capital, technology, manufacturers and governments together to structure and deliver climate infrastructure at scale across air, water and energy.
