UNCTAD Bets on Network, Not New Exchange, to Fix Carbon Markets

Carbon pricing mechanisms covered nearly 30% of global greenhouse gas emissions and generated more than $107 billion in government revenue in 2025, according to the World Bank's 2026 State and Trends of Carbon Pricing report. That is the pool of money UN Trade and Development (UNCTAD) wants to connect more effectively — and its chosen instrument debuts November 12 in Antalya, Türkiye, at COP31.

The new Global Carbon Market Network is deliberately not another trading platform. Instead, UNCTAD plans to bring together carbon exchanges, financial institutions and other market participants to make existing systems work together, facilitate cross-border transactions and rebuild investor confidence in a market dogged by transparency failures, inconsistent standards and questionable credit quality.

For practitioners, that distinction matters. Rather than adding venue capacity, the network targets the plumbing: verification requirements, registries and trading frameworks that currently differ across jurisdictions and complicate international deals.

What is actually broken?

International carbon trading suffers from fragmentation. Verification requirements vary, registries don't talk to each other, and trading frameworks diverge from one market to the next. Two problems have done particular damage: unreliable credits and double counting. Both have pushed potential buyers and investors to the sidelines.

UNCTAD's answer is institutional cooperation rather than rulemaking. The network will run:

• technical exchanges between market institutions;
• initiatives to improve measurement and verification of emissions reductions;
• exploration of digital technologies that could cut transaction costs and raise transparency.

The initiative is also positioned to support Article 6 of the Paris Agreement, the framework that lets countries trade carbon credits and internationally transferred emissions reductions. Article 6 has been slow to operationalise, and a functioning cross-market infrastructure layer is one of the pieces it still lacks.

Who stands to gain?

The geographic mismatch in today's carbon market is structural. Many carbon credit projects originate in developing economies, while the buyers sit mostly in wealthier ones. Better connections between markets should, in theory, redirect more of that $107 billion-plus revenue stream toward the countries hosting the projects.

Theory and practice have diverged so far. Access to international carbon finance stays constrained by three frictions: high verification costs, regulatory uncertainty and doubts about project credibility. A credit buyer in Europe or North America has no shortage of reasons to walk away from a project in the Global South — and often does.

The network's opening programme reflects those bottlenecks. It includes capacity-building, market benchmarking and direct engagement with regulators, aimed at the institutions that decide whether a credit is bankable.

What decides whether this works?

UNCTAD itself frames the test plainly. The network's longer-term success will depend on whether improved cooperation translates into greater investment and demand for credible carbon credits. Cooperation that stays at the level of working groups and memoranda changes nothing for project developers still paying verification costs they can't afford.

The timing gives the initiative a real tailwind. Carbon pricing keeps expanding globally, and the revenue figure — over $107 billion in a single year — shows the money is already moving. The question the Antalya launch has to answer is whether the network can channel it across borders instead of around them.

The milestone to watch comes after COP31: whether the first benchmarking outputs and regulator engagement produce a measurable rise in cross-border credit transactions. That, not the launch event itself, is the verdict the market will price in.
