## Summary

Carbonable has built a product that lets companies prove their carbon commitments using zero-knowledge proofs without disclosing private data. Companies use its Ecopilot tool to lock in carbon credits based on emissions forecasts, then generate a cryptographic proof, for example that they are offsetting 70% of emissions this year, without revealing the underlying credit or emissions figures. Proofs can cover a single year, such as 2023, or a full multi-year plan, and any verifier can check them without access to private data. The article says the tools used include Circom and Garaga.

Carbon-neutral by 2050? Cool. But proving it? That’s where things get tricky. At Carbonable we’ve worked on a whole new product, letting companies prove their carbon commitments without giving up their private data. Let’s break it down.

The Big Problem: Proving Net-Zero Without Leaking Sensitive Info

The race to Net-Zero is real. Companies are pledging big, aiming to hit carbon targets by 2050. But sharing progress isn’t as simple as posting your CO₂ emissions on the internet. That’s sensitive stuff — nobody wants to spill all the details on credits and emissions forecasts.

Enter Carbonable. We’re all about transparency and privacy. Using Zero-Knowledge Proofs (ZKPs), we make it possible for companies to show they’re on track to meet their targets— without revealing the inner workings of their carbon data. The key concept here is ✨ Provability ✨

How Carbonable Keeps It Simple (and Private) for Companies

Plan, Lock, and Prove

Companies start by using Ecopilot (Carbonable’s tool) to lock in carbon credits based on their emissions forecasts. Think of it as setting up a long-term game plan. But instead of saying, “Hey, here’s every detail about our credits and emissions,” they hit a button to create a cryptographic proof. That’s right — no sensitive data leaks, just a proof they’re hitting their goals.

So, say a company is offsetting 70% of its emissions this year. They can whip up a proof that says exactly that, without showing how many credits or the specific figures involved. Then they can drop it into an ESG report, throw it up on Twitter, or hand it over to an auditor.

Single-Year Proofs or Full Plan Verification? You Do You

Want to prove 2023? Done. Prefer to show your entire multi-year plan? Easy. Carbonable lets companies verify progress one year at a time or show the whole timeline.

On the Other Side: How Anyone Can Verify Without Seeing Private Data

Imagine you’re an auditor, a regulator, or just someone who cares about the planet. How do you know these Net-Zero claims are legit without seeing the whole data dump? Here’s the cool part: you don’t need it.

Any verifier can confirm a company’s claims & ZKPs without needing access to private data. This isn’t limited to just one system — anyone can set up a way to check these proofs. You see the claim, you see the proof, and you get the assurance that it’s backed by verifiable, unchangeable data. Everything you need is there, just not the private stuff.

How It Works Under the Hood: Zero-Knowledge Proofs in Action

For the tech-curious, we use tools like Circom and Garaga to build and verify these proofs. We’ll dive deeper into this in an upcoming article.

Wrapping It Up: Carbonable’s Bold Move Toward Private and Verifiable Carbon Neutrality

Carbonable is redefining how companies prove their way to Net-Zero. For companies, it’s the comfort of privacy without compromise. For everyone else, it’s the confidence of knowing the numbers add up.

This is the future of ESG — private, secure, and backed by proof. Ready to see Net-Zero claims that are both legit and locked down? Join us as we build the path to a transparent, privacy-first Net-Zero future.
