A point of view from the Repricing Carbon project. New to this? Start with What Is a Carbon Credit?
I have spent years working in sustainability, in solar energy, in permaculture, in helping mission-driven businesses tell their story. Carbon credits were the newer frontier for me, so over the last few months I set out to learn this market from the outside in, reading, asking questions, and writing down what I understood so far. I went in curious and a little skeptical. I came out with one conviction I cannot shake, and it is the reason I am writing this.
If carbon credits are going to have a real future, the most important thing this market can build is not another exchange, another registry, or another marketplace. It is an independent, unbiased third party whose entire job is to grade credits, and to keep grading them, for as long as the market exists.
A market that sells promises cannot run on the honor system. Someone independent has to check the promises, and keep checking them.
Why grading is the keystone
A carbon credit is a promise. It says a specific ton of carbon was avoided or removed, that it would not have happened anyway, and that it will stay that way. You cannot see a credit. You cannot kick its tires. You are trusting that the promise is real.
For years, buyers trusted that promise because a registry had stamped it. Then they learned the hard way that a stamp means a project followed the rules, not that the credit is actually good. That gap is what broke confidence in the market, and it is the gap that only an independent grader can close.
This is not a new idea. It is the oldest idea in finance. The bond market does not ask companies to grade their own debt. It has Moody’s and S&P. The stock market does not take a company’s word for its earnings. It has auditors and analysts. Every serious market eventually separates the people who sell an asset from the people who judge it. Carbon is simply the newest market to learn that lesson.
The part most people miss: it has to be ongoing
Here is the piece I did not appreciate until I went deep. A rating is not a one-time stamp. It is a living judgment.
A project that looked strong in 2022 can look weak in 2026. A forest can burn. A baseline can be proven too generous. New science can change what we know about a whole category of credits. If the grading happens once and then sits frozen, it rots. The only version of this that works is one where someone is paying attention continuously, updating the grade as the facts change, and telling buyers when something they bought no longer holds up.
A credit’s quality is not a fact you check once. It is a story that keeps unfolding. The grader’s job is to keep reading it.
The hard truth about market cycles
Now the part that worries me, and the reason I think this needs to be said out loud.
Carbon markets go up and down. When prices fall and budgets tighten, the grading function is exactly the kind of thing a shaky market is tempted to treat as optional. Why pay for a referee when volumes are down and everyone is cutting costs?
That instinct is precisely backwards. You do not fire the referee because the game got ugly. You need the referee most when it does. The moments when trust is collapsing are the moments when an independent, credible grade is worth the most, not the least. A market that only funds its quality control in the good times does not have quality control. It has a fair-weather decoration.
So the entity that does this work cannot be a startup that disappears in the next downturn. It has to be a supported, established institution, built to outlast the cycles, the way the great rating agencies and audit firms outlasted every recession that came for them. That permanence is not a nice-to-have. It is the whole point.
Why it is worth it in the long run
This is not charity. It is the engine that makes the entire market work.
When grading is independent and durable, a chain reaction follows. Buyers can finally tell strong credits from weak ones. They start paying more for the strong ones. Developers notice, and build better projects to earn the better grades. The quality of the whole supply rises. The headlines improve. More buyers come back. The market grows, this time on a foundation that can hold weight.
None of that happens without the grader sitting in the middle, honest and unmoved by the noise. The grading is not a tax on the market. It is the thing that lets the market deserve to exist.
Who is actually doing this
A small number of firms are building exactly this layer right now. The one I keep coming back to is Calyx Global. It was built from the ground up to be what I have described: independent, funded by the buyers rather than the projects, committed to updating its judgments as the facts change, and serious enough about the work to be conservative when conservatism is unpopular. The people who started it treat this as infrastructure, not a trend. That is the right way to treat it.
I am not writing this because anyone asked me to. I am writing it because after months of learning this market, the grading layer is the part I would stake my own reputation on. It is the highest-leverage place to stand if you actually want carbon credits to become something the world can trust.
Where I land
The future of carbon credits does not run through hype, or volume, or the next clever financial product. It runs through trust, and trust runs through independent grading that is rigorous, ongoing, and built to last. If we want to keep selling carbon credits, and I think we should, then funding and defending that grading layer is the most important thing we can do. Not when it is convenient. Always.
That is the conviction I came away with. I would genuinely like to hear from anyone who sees it differently, and from anyone who is helping build it.
A note from the author. I have spent the better part of two decades working in sustainability: in solar and clean energy, in permaculture and regenerative land projects, and in marketing the mission-driven businesses trying to do this right. Carbon credits are the part of that world I came to most recently, and I am still very much a learner here. There are 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 here, I apologize, and I would like to hear about it so I can learn and correct it. I am writing to start a conversation, not to have the last word. That is the whole point. If this piece resonated, share it. If you see it differently, even better. Let’s talk.
