Can a company allocate 100% of renewable electricity to only one version of the same product?

Hi everyone,

I’m working with a client who manufactures a single product through a common production line powered by a mix of renewable and non-renewable electricity (from the same internal grid).

They are now planning to sell two versions of this product:

One labeled as “low-carbon”

The other as standard or regular

The catch: they want to allocate 100% of the renewable electricity (which they procure via PPAs or RECs) only to the low-carbon product, and assign none of it to the regular one — even though both are made in the same facility using the same mixed energy source.

There’s no physical separation of electricity streams — it’s all attributional.

From what I understand, this might be allowed under frameworks like the GHG Protocol Scope 2 Guidance (market-based method) and ISO 14067, as long as:

They don’t double-count the renewable electricity

The RE claims are certified and verifiable

The allocation will be 100 percent of renewable electricity to low carbon.

But ethically or from an LCA best-practice point of view — is this considered fair or misleading?

Would love to hear your thoughts or see if anyone has dealt with a similar case. Your input would really help me guide the client better.

Thanks in advance!
