Labelling and Serialisation

This section outlines the principles of labelling and serialisation within the ERS Registry, highlighting their role in ensuring the uniqueness and traceability of Restoration Units.

UNIQUENESS

1. Each Restoration Unit within the ERS Registry is unique and represents the net removal of one tonne of carbon dioxide equivalent, alongside positive impacts on ecological recovery and local livelihoods. To maintain this uniqueness, the following principles apply:
2. Ownership: A unit is owned by only one account at a time within the ERS Registry.
3. Transfer: A unit can be transferred to only one account at a time within the ERS Registry.

SERIALISATION

Serialisation is a critical aspect of unit management. It ensures transparency and accountability and protects against the risks of double counting. The ERS Registry employs a unique serialisation methodology.

1. All units within the ERS Registry are assigned a unique serial number with the following format: 

ERS-[project type]-[project id]-[countrycode]-[unit type]-

[issuance date or vintage]-[batch]-[block start]-[block end] 

2. System Identifier or Originating Registry: ERS
3. Project Type:
   1. 0 - for Reforestation;
   2. 1 - for Terrestrial Forest Restoration.
4. Country Code;
5. Unit Type;
6. Issuance date (for PRU) or vintage (for VRU);
7. Batch Number: Numeric value assigned to each batch of credits per originating issuance;
8. Serial Block Start: Numeric values assigned by the registry from 1 - 999,999,999;
9. Serial Block End: Numeric values assigned by the registry from 1 - 999,999,999.

These unique and immutable serial numbers allow for the complete traceability of each unit throughout its entire lifecycle.

PUBLIC INFORMATION AND CROSS-REFERENCE

Information about the Project's location is available on the Project page, using the project-ID represented in the serial number. Stakeholders can cross-reference this information with Project publications that provide geodetic coordinates, ensuring transparency regarding each unique unit's country and sector of origin, vintage, and original (and, if relevant, revised) Project registration date.

LABELLING

1. Assets meeting the eligibility requirements for ICAO's CORSIA, ICROA, and IC-VCM are labelled as such. Labels are reflected in the data warehouse views.
2. Retroactive labelling is applied for previously issued units, ensuring compliance with international standards.
