AEA Ammonia Certification System

The AEA Ammonia Certification System is now operational.

Read the announcement (April 27, 2026).

The AEA Ammonia Certification System is a global certification system designed to facilitate the transparent, trusted international trade of low-emission ammonia. It enables producers, traders, and consumers to demonstrate key environmental attributes – namely carbon footprint and origin – using independently verified data.

• The Pilot phase began in September 2025 and remains open to new participants.
• The AEA Ammonia Registry, built and operated by MiQ, enables the generation, transfer, and retirement of certificates, providing secure data transfer, transparency, and traceability across the ammonia supply chain.
• Auditors provide independent verification that the environmental attributes are correctly assigned and the chain of custody model is correctly applied.
• The System Documents describe the full set of rules and methodologies that must be followed by any participant.

The AEA Ammonia Certification System is a voluntary system open to all entities in the ammonia value chain, including producers, traders and distributors, and consumers. Participation is open to both members and non-members of the AEA.

The System aims to enable differentiation in the marketplace for low-emission ammonia, enhance credibility throughout the supply chain, facilitate cross-border trade, and support alignment between multiple certification schemes, standards, and regulations.

The System encompasses:

• Pre-certification of facilities that have not yet been built. This provides project developers with a credible evaluation of the environmental attributes of future production, to support offtake and financing discussions.
• Certification of ammonia produced at facilities that are already operational. This enables full disclosure to the consumer of the environmental attributes of ammonia, and supports demonstration of compliance with regional or global requirements for emission reductions.
• Global ammonia registry to enable transfers of certificates across the value chain, from generation, through trading, to retirement. The Registry supports three distinct chain of custody models: Segregated, Mass Balance, and Book and Claim.
