The expansion of the EU Carbon Border Adjustment Mechanism (CBAM) is increasing interest in Guarantees of Origin (GOs) and other renewable electricity certificates. However, these instruments do not provide the same protection as a qualifying physical power purchase agreement (PPA), nor do they perform the same function as a financial hedge against carbon prices.
For companies importing electricity or sourcing power for the production of CBAM-covered goods, the distinction is commercially important. A Guarantee of Origin documents a renewable electricity attribute, but does not by itself establish eligibility for actual-emissions treatment under CBAM.
Three instruments, three different functions
A GO records an environmental attribute associated with renewable electricity generation. It can support corporate renewable-energy claims and contribute to a broader package of evidence about electricity sourcing.
CBAM’s requirements for demonstrating actual electricity emissions, however, extend beyond ownership or cancellation of an attribute certificate. The regulatory framework considers the connection between electricity generation, contractual arrangements, physical delivery and the evidence needed to substantiate the emissions claim.
For electricity imports, relevant conditions include an identified generating installation, qualifying contractual arrangements, physical transmission, nominated capacity and independent verification. The methodology for electricity consumed in the production of goods also distinguishes between generic grid electricity and electricity supported by qualifying contractual or technical arrangements.
Consequently, a GO alone cannot replace the physical and evidentiary requirements applicable to actual-emissions treatment.
The instruments address separate elements of carbon exposure:
- EUA hedges manage movements in the carbon-price reference.
- Qualifying PPAs and supporting physical evidence can help establish a lower emissions quantity where the CBAM methodology permits it.
- Guarantees of Origin document renewable electricity attributes and can support wider renewable-energy claims.
Using these instruments together may be commercially valuable, but treating them as interchangeable can leave companies with carbon exposure they believe they have already addressed.
Evidence quality becomes a commercial differentiator
The distinction is likely to become increasingly relevant as demand grows for low-carbon industrial products and buyers place greater emphasis on the credibility of suppliers’ electricity claims.
Customers may need to establish whether a supplier’s renewable electricity sourcing is supported only by certificate-based accounting or by contractual, operational and technical evidence capable of withstanding CBAM verification.
The commercial value of a low-carbon electricity claim therefore depends on the quality, consistency and traceability of the underlying documentation. A certificate can support an environmental attribute claim without necessarily changing the emissions quantity recognised in a regulatory calculation.
This creates additional requirements for electricity suppliers, industrial producers and traders. They must understand which documents support renewable-energy claims and which evidence is required to demonstrate eligibility under the relevant CBAM rules.
Bundled renewable electricity products
The distinction also creates opportunities for utilities and electricity traders to develop more comprehensive renewable supply products.
A structured offering could combine physical electricity delivery, PPA documentation, metering records, scheduling information and Guarantees of Origin. Such arrangements could provide customers with both electricity procurement services and a more complete evidence package for carbon reporting.
The value of these products would depend on whether the contractual and operational structure satisfies the applicable regulatory conditions. Bundling certificates with physical electricity does not automatically establish CBAM eligibility, but it can form part of a broader, properly documented supply arrangement.
CBAM is raising the evidentiary standard for renewable electricity claims. Guarantees of Origin remain useful instruments for documenting renewable attributes, but the potential reduction in recognised carbon exposure depends on whether the complete contractual, physical and verification requirements are met.
