Code Managers

•• Accredited Codes under the I-REC Standard

Providing detailed rules and regulations for specific geographic regions and energy carriers

The International REC Standard Foundation’s (I-REC Standard’s) International Attribute Tracking Standard (Standard) provides general principles and definitions for a robust attribute tracking mechanism. Underneath this overarching Standard, organizations can develop more detailed Product Code documents that set specific rules for specific regions or products such as electricity, gases, heating, cooling, or even non-energy products. These Codes can be developed independently of the I-REC Standard but must be reviewed and Accredited by the I-REC Standard to ensure consistency with the Standard. This allows a variety of products to be reliably tracked under one familiar and internationally recognized name: I-RECs.

Once accredited, the owner of a Code is known as a Code Manager. Code Managers can be for-profit organizations, non-profit organizations, or governmental bodies that see a need and opportunity to facilitate new markets. Having various code managers enables implementation by local national authorities while maintaining the adherence to robust tracking mechanisms in line with the Standard.
