Release of NORSUS’ Methodology for Residual Mix calculation methodology in I-REC(E) issuing countries

*Since the date of this news item’s publication, the organization ‘The International REC Standard Foundation’ has changed to ‘The International Tracking Standard Foundation: Founder of I-REC (I-TRACK Foundation).’

 

In the earlier part of 2023, the Norwegian Institute for Sustainability Research (NORSUS), began research on developing a Residual Mix Calculation methodology for I-REC(E) issuing countries. NORSUS had been working on a variant of the Issuance-based method (deadline for issuance, no expiry) used by other attribute tracking systems across the globe.

The residual mix of a country represents the share of untracked electricity supply for which the energy source is not proven through reliable EAC tracking schemes. The GHG Protocol Scope 2 Guidance advises those companies without specified purchases must use a residual mix—a type of emission factor representing the average emissions from all unclaimed energy. However, residual mix emission factors characterizing the GHG intensity of unclaimed or publicly shared electricity are not frequently available for consumer scope 2 calculations.

The NORSUS methodology report can be found here.

The NORSYS country case report can be found here.

The I-REC Standard Foundation is proud to have been able to collaborate with NORSUS in the development of this report and to be able to ensure its open publication, thereby contributing to increasing transparency and robust EAC markets globally.
