Rebranding Without Greenwashing: A Practical Checklist

Rebrands are where overclaiming creeps in. You’ve got a new look, a renewed sense of purpose, and a designer asking what the brand stands for now — and “we’re more sustainable than we used to be” is a tempting thing to write across the top of it. The trouble is that the visual refresh moves a lot faster than the operational reality, and the gap between the two is precisely what greenwashing is.

The rules around this have tightened. The CMA’s Green Claims Code and the ASA’s enforcement of the CAP advertising rules mean a vague green claim is no longer low-risk — it’s a compliance exposure. None of that should put you off rebranding around sustainability if it’s genuine. It just means doing it carefully. Here’s the checklist we run through before a single line of green copy goes live.

Substantiate before you state

The single most important rule, and the one most rebrands get backwards. Decide what’s true first, then write the brand around it — not the other way round. The CMA’s working standard is that you must be able to substantiate a claim at the moment you make it, so every public-facing line needs something behind it: a certificate, an audit, a measured figure. If you’re writing the claim and then hoping to find the evidence later, you’ve already got it wrong. This is the same discipline we cover in detail on making sustainability claims without greenwashing.

Be specific about scope

Vague claims are the ones that fail. “Sustainable packaging” invites the question — all of it, or the box but not the liner? A claim like “our outer packaging is made from 80% recycled card” is specific, checkable, and far safer, even though it sounds less sweeping. Work through your claims and pin each one to a defined scope: which product, which material, which part of the process. The narrower and more precise the claim, the harder it is to challenge.

Avoid absolutes and comparatives you can’t back

A short list of phrases to handle with real care:

• Absolute claims — “zero impact”, “100% sustainable”, “completely green”. These are almost impossible to evidence across a full life cycle, which is exactly the standard the Green Claims Code applies. Avoid them unless you genuinely can prove them end to end.
• “Carbon neutral” without scope — if it rests on offsets, you have to say so, and the offsets have to be credible. Stating it bare is one of the most heavily scrutinised claims going.
• Comparatives — “greener than before”, “more sustainable than the alternatives”. Fine in principle, but you need the baseline and the data to support the comparison, and it has to be a fair, like-for-like one.

If a claim can’t survive someone asking “compared to what, and how do you know?”, it shouldn’t be in the rebrand.

Don’t hide the trade-offs

Most real sustainability stories have a caveat, and burying it is a fast route to a complaint. If a product is recyclable but only at specialist facilities, say so. If your renewable energy covers the office but not the delivery fleet, don’t let the brand imply otherwise. The Code is explicit that claims mustn’t omit or hide material information. Being upfront about the limits of what you’ve achieved reads as more credible, not less — and it’s the honest position anyway.

Keep the evidence on file

Pull together a single folder — call it a claims register — that holds the proof for every public claim, with the dates each one applies to: energy certificates, supplier declarations, lifecycle figures, test results. Two reasons. First, if the ASA or CMA, a journalist, or a sharp customer asks how you know, you can answer quickly rather than scrambling. Second, the act of assembling it is its own audit. More than once we’ve watched a business start filling in the register and quietly drop a claim because the evidence simply wasn’t there.

Make the whole identity match the operating reality

A rebrand isn’t just a logo. It’s the copy, the photography, the packaging, the social bios, the email footer — and all of it makes claims, including the visual parts. Earthy colours, leaves, and recycled-look paper stock imply environmental credentials just as loudly as words do. The ASA has ruled against imagery that overstated a company’s green credentials even where the text was technically careful. So check the visuals against the same standard as the copy: does the whole identity reflect what the business actually does, or does it dress up an ordinary operation as a green one? If you’re commissioning this work out, build the substantiation in from the start — our notes on how to brief a branding agency cover how to fold it into the brief rather than bolting it on at the end.

Don’t imply more than you do

The subtlest failure, and the one that catches well-meaning businesses. You can be technically accurate and still mislead by implication — a single recycled product line that makes the entire company look green, or a one-off planting initiative that reads like a core commitment. Step back and ask what impression the rebrand leaves overall, not just whether each individual claim is defensible. The honest test is whether a reasonable customer would come away believing something truer than the facts. If the answer is no, scale the claims back to fit.

What safe looks like in practice is duller than the hype but a great deal sturdier. On our own site we say the work is hosted on verified renewable energy, checked through The Green Web Foundation — specific, evidenced, and easy to confirm. That’s the shape every claim in a rebrand should take.

A quick last word

A genuine sustainability story is worth telling, and a rebrand is a good moment to tell it — provided the brand never gets ahead of the business. Run your claims through this checklist before you sign anything off, and you’ll end up with an identity you can stand behind when someone asks the hard question.
