Carbon markets are rapidly evolving toward higher integrity, stronger regulation and global interoperability. Governments need national digital infrastructure that aligns with the Paris Agreement, while enterprises require reliable systems to participate in carbon trading, climate finance and decarbonisation programmes.
Xeptagon delivers this through a complete, end-to-end ecosystem built on the same digital architecture we designed, developed and continue to maintain for the United Nations Development Programme (UNDP). These systems are deployed across multiple countries and form the backbone of national registries, MRV platforms, transparency systems and Article 6 operations.
Our technology provides the trust, auditability and compliance needed for governments and organisations to operate modern, high-integrity carbon and climate finance markets.
Supports carbon credits, emissions allowances, SAF book-and-claim units, renewable energy certificates and other regulated environmental assets within a unified system. Designed to accommodate multiple methodologies and programme structures under one platform.
Enables regulators to define and easily update approval hierarchies, issuance rules and compliance checkpoints without custom redevelopment. Every action is logged and auditable, ensuring institutional control and regulatory oversight.
Manages issuance, allocation, transfer, retirement and cancellation of environmental units through structured, traceable processes. Ensures complete ownership history and prevents double issuance or double counting.
Supports Article 6 authorization workflows, ITMO tracking and corresponding adjustment accounting. Also enables emissions trading system (ETS) allowance allocation, compliance tracking and regulator-facing reporting.
Designed to connect with national registries, voluntary standards, CAD Trust and UNFCCC-aligned reporting environments. Enables seamless asset movement and reporting across domestic and international systems.
Offers integration with blockchain such as Hedera Guardian for immutable anchoring and verifiable lifecycle tracking. Tokenization enhances transparency while preserving registry authority as the source of truth.
Proven through deployments with governments, UN agencies and multilateral programmes, the registry delivers trusted infrastructure for regulated environmental markets and long-term institutional use.

Xeptagon’s platforms are designed as modular, governance-grade systems that can be extended across multiple regulated climate and market use cases. The same core registry, data, trading and governance foundations can be configured to support sector-specific requirements as policies and markets evolve.
Below are selected use cases currently supported or under active deployment.
Xeptagon supports registry and book-and-claim systems for Sustainable Aviation Fuel (SAF), enabling transparent accounting of SAF attributes across fuel producers, airlines and corporate buyers. These systems track SAF production, allocation, transfer and claim retirement, ensuring credible emissions reduction accounting without double counting. Built on the same governance-grade foundations as national carbon registries, SAF systems integrate with enterprise sustainability reporting and aviation decarbonisation initiatives.
Xeptagon provides digital infrastructure for emissions trading systems (ETS), including allowance issuance, allocation management, transfer tracking and compliance reporting. Governments can manage allocation schedules, monitor regulated entities and support transparent market operations using auditable, regulator-ready systems aligned with national climate policy objectives.
Xeptagon systems can be extended to enterprise use cases such as supply-chain emissions tracking, CBAM-aligned reporting and sector-specific climate data governance. These configurations allow enterprises to operate within regulated frameworks while maintaining alignment with national and international climate systems.
