A plain-English explainer from the Repricing Carbon series. New here? Start with What Is a Carbon Credit?
Here is the fear that keeps a lot of would-be buyers on the sidelines: they want to support climate action, but they are terrified of being accused of greenwashing. It is a fair fear. The good news is that avoiding it is mostly about a few honest habits, not luck. Let me walk through them the way I had to learn them.
What greenwashing actually means here
Greenwashing is making your climate effort sound bigger or cleaner than it really is. In the carbon credit world, it usually takes one of a few forms: buying cheap, low-quality credits and calling the job done, claiming credit for reductions that did not really happen, or using credits as a substitute for cutting your own emissions instead of an addition to it.
The cardinal rule: reduce first, offset second. Credits are meant to handle the emissions you cannot yet eliminate, not to excuse the ones you could.
Almost every greenwashing accusation traces back to breaking that rule, or to claiming more than the credits can support.
The claim is where it lives or dies
This was the part that surprised me. The greenwashing risk is often less about the credit you bought and more about the words you use afterward. Two companies can buy the exact same credit. One makes a careful claim and is fine. The other overstates it and gets burned. The credit was identical. The language was not.
That is why the market has moved toward more careful phrasing. A couple of distinctions do most of the work:
“Offsetting” claim
Saying a credit cancels out your emissions, ton for ton. A strong claim that invites strong scrutiny, and the one most likely to draw fire if the credit is weak.
“Contribution” claim
Saying you funded climate action, without claiming it erased your own footprint. More modest, far easier to defend, and increasingly the safer choice.
Neither is dishonest. The mistake is making the first kind of claim with a credit that can only support the second.
The referees who wrote the rulebook
You do not have to invent the safe wording yourself. A body called VCMI, the Voluntary Carbon Markets Integrity Initiative, has published a Claims Code that spells out what a company is allowed to say depending on how much it has reduced its own emissions and how good its credits are. Pair that with SBTi, which defines a credible emissions-reduction target in the first place, and you have a path that is hard to attack: cut your own emissions on a real target, buy high-integrity credits for the rest, and use the claim the rulebook permits.
A short checklist for a defensible purchase
Do those four things and the accusation mostly loses its grip. Greenwashing thrives on vagueness and shortcuts. Honesty, documentation, and a credible rating are how you starve it.
Where to go next
So the way out of the fear is not to avoid the market. It is to reduce first, buy well, and say only what you can back up. To see how a whole team now shares this responsibility across legal, brand, and procurement, read why buying carbon credits is a team decision. And to make sure the credits underneath your claim are sound, start with the five quality questions.
A note from the author. I am a writer who cares about sustainability, and when it comes to carbon credits I am still very much a learner. There are a lot of people who know this market far better than I do, and I have real respect for the work they have put into building it. If I got something wrong in here, I apologize, and I would genuinely like to hear about it so I can learn and correct it. I am writing this to start a conversation, not to have the last word. That is the whole point. This is a learning experience for me too, and the conversation is what moves all of us forward. If this piece helped you, share it. If you see it differently, even better. Let’s talk.
