1. Introduction
Once carbon programme that was added to the system is Authorized, a unique serial number should be generated for every programme by the Carbon Registry.
2. Serial Number Generator
2.1 Serial Number Standard
Serial Number character length:
| Block Name | Type | Possible Values | | --- | --- | --- | | Country Code (as per ISO 3166) | String | ISO 3166-1 alpha-2 value | | Type of Credit/Unit | String | ITMO | | Sectoral Scope Number (as per CDM) | Integer | 1-15 | Unique Programme ID | Integer | XXX | | Year | Integer | 20XX | | Blank/ any other | String | 0 | | Unit Serial Block - Start | Integer | 1 - X | | Unit Serial Block - End | Integer | XXXXXX |
The blocks will be separated by the delimiter dash (-) Eg: VU-ITMO-11-356-2022-0-27-35
2.2 Country Code
Standard needs to be followed ISO 3166-1 alpha-2
two-letter country codes.
Eg. | Country Name | ISO 3166-1 alpha-2 code | | --- | --- | | Costa Rica | CR | | Fiji | FJ |
2.3 Type of Credit/ Unit
Carbon credit measurement unit: ITMO
2.4 Sectoral Scope Number
According to the UNFCCC - CDM (Clean Development Mechanism methodologies, identified Sectors and Sectoral scope numbers are as follows:
| Scope Number | Sectoral Scope | | --- | --- | | 1 | Energy industries (renewable - / non-renewable sources) | | 2 | Energy distribution | | 3 | Energy demand | | 4 | Manufacturing industries | | 5 | Chemical industries | | 6 | Construction | | 7 | Transport | | 8 | Mining/mineral production | | 9 | Metal production | | 10 | Fugitive emissions from fuels (solid, oil and gas) | | 11 | Fugitive emissions from production and consumption of halocarbons and sulphur hexafluoride | | 12 | Solvent use | | 13 | Waste handling and disposal | | 14 | Afforestation and reforestation | | 15 | Agriculture |
2.5 Unique Programme ID
format: XXX, When it exceeds the limit of possibilities it will go beyond 3 digits.
Contains only numbers
2.6 Unit Serial Block – Start
Serial Block Start – Total number of credits before issuing the credits for the programme + 1 The start of the serial block will be represented without the decimal point of the credit value. It will be represented as a rounded integer.
2.7 Unit Serial Block – End
Serial Block End – Total number of credits after issuing the credits for the programme. The end of the serial block will be represented without the decimal point of the credit value. It will be represented as a rounded integer.
Eg:
| Programme Current | Block End | Credit Value | Credit Value (Rounded) | Serial Block Start | Serial Block End | | --- | --- | --- | --- | --- | --- | | Programme 1 | | 25.51 | 26 | 1 | 26 | | Programme 2 | 26 | 10.000 | 10 | 27 | 36 | | Programme 3 | 36 | 5.4341 | 5 | 37 | 41 | | Programme 4 | 41 | 0.1285 | 0 | Programme Rejected as credit value is 0. | | Programme 5 | 41 | 14.7 | 15 | 42 | 56 |
3. Usage
import { generateSerialNumber } from '@undp/serial-number-gen';
const serialNo = generateSerialNumber(countryCodeA2, sectoralScope, programmeId, year, startBlock, endBlock, creditUnit);
Parameters
| Block Name | Description | | --- | --- | | countryCodeA2 | Country Code (as per ISO 3166) | | sectoralScope | Sectoral Scope Number (as per CDM) (1-15) | programmeId | Unique Programme ID | | Year | Year in format XXXX | | startBlock | Current ledger credit value (inclusive)| | endBlock | Credit value with the current program (inclusive)| | creditUnit | Carbon credit unit (Eg: ITMO)
