Carbon Registry Market (2026-2036)

Registries are the essential infrastructure that establishes the integrity of carbon credits by issuing unique serial numbers, tracking ownership, and recording retirement to prevent double counting. Every credit transacted in voluntary or compliance markets is issued, held, transferred, and ultimately retired in a registry, making these systems the definitive record of market activity. The scale of this function is substantial: according to Verra, more than 1.3 billion credits have been issued under the Verified Carbon Standard, of which over 776 million have been retired. Registries generate revenue by charging issuance and registration fees, account and holding fees, and transaction and retirement fees, meaning that registry income grows with the volume of credits issued and transacted, tying registry economics directly to the expansion of carbon markets.

The operationalization of Article 6 of the Paris Agreement is creating a new layer of registry infrastructure and demand among governments. At COP29 in 2024, parties approved the standards needed to operationalize the Article 6.4 mechanism, now the Paris Agreement Crediting Mechanism, and the UNFCCC secretariat is developing its mechanism registry, with an interim registry intended to hold Article 6.4 emission reductions. Under Article 6.2, participating countries are establishing national registries capable of tracking internationally transferred mitigation outcomes and applying corresponding adjustments. This is driving demand for new government and international registries, connectivity between national and international systems, and registry technology, expanding the market beyond established voluntary programs to sovereign participants.

Concerns about double counting and transparency are driving investment in interoperability and connected registry infrastructure. Because credits are issued across multiple independent registries, the risk of the same reduction being counted more than once is a central integrity concern, and initiatives are emerging to connect registry data. The Climate Action Data Trust, a World Bank, IETA, and Singapore initiative, links major carbon registry data through a decentralized metadata platform, and as of 2025 had connected around a dozen registries covering an estimated 90% of global credit issuances. Alongside integrity frameworks such as the Core Carbon Principles, these initiatives are driving demand for standardized data, connectivity, and transparency infrastructure, creating opportunities for registry operators and technology providers.

The integration of digital MRV and the modernization of registry technology are transforming registries from static databases into dynamic, data-connected platforms. Registries are increasingly linked to digital measurement, reporting, and verification systems that support faster and more automated issuance, and some are adopting real-time data connections and application programming interfaces. Digital registry providers, including those using distributed ledger technology such as Toucan, Regen Network, and Riverse, are building programmable registry infrastructure, while established registries modernize their platforms. This modernization improves efficiency, transparency, and auditability, and expands the technology component of the market, creating demand for registry software and platform services alongside traditional registry operations.

The emergence of durable carbon removals and nature credits is broadening the scope and value of registry infrastructure. Dedicated registries for engineered and durable carbon dioxide removal, including Isometric, Puro.earth, and Riverse, have developed specialized issuance and tracking systems for high-value removal credits, while biodiversity and nature credits are creating demand for new registry capabilities. These higher-value credit classes command premium issuance and require rigorous tracking, increasing the value of registry services per credit. As carbon markets diversify beyond avoidance credits toward removals and nature outcomes, registries that can support new credit types and methodologies are positioned to capture growing revenue.

North America is the largest regional market, accounting for approximately 35% of the global carbon registry market in 2026. The region hosts several of the world's leading voluntary carbon registries, including Verra, the American Carbon Registry, and the Climate Action Reserve, as well as compliance market infrastructure such as the tracking systems used by the Western Climate Initiative and California's cap-and-trade program. A large and active voluntary carbon market, a growing pipeline of removal and nature projects, and the presence of registry technology providers reinforce North America's position as the commercial core of the market. Continued growth in credit issuance and the development of new credit classes sustain demand for registry services and infrastructure.

Europe accounts for around 27% of global carbon registry market revenue in 2026. The region hosts Gold Standard, one of the leading voluntary registries, and operates the European Union Emissions Trading System through the Union Registry, one of the world's largest compliance registries. The United Kingdom operates its own emissions trading registry, and European governments are participating actively in Article 6. Strong policy support for carbon market integrity and transparency, together with the presence of standards bodies and technology providers, drives demand for registry services and interoperability infrastructure across the region.

Asia-Pacific is projected to be the fastest-growing regional market during the forecast period, driven by the expansion of compliance carbon markets and Article 6 participation. China operates the world's largest emissions trading system by covered emissions, supported by national registry infrastructure, while India's Carbon Credit Trading Scheme, and emerging markets in Indonesia, Japan, and Southeast Asia, are establishing registries and trading systems. Many countries in the region are prominent hosts of Article 6 projects and are developing national registries to track internationally transferred mitigation outcomes. Rising credit issuance and government investment in registry infrastructure are expected to drive strong regional growth.
