# What Is Carbon Credit?

> A carbon credit is a tradable certificate representing one metric ton of carbon dioxide (or equivalent greenhouse gas) removed from or not emitted into the atmosphere — used in voluntary or compliance markets to offset emissions.

**A carbon credit** represents one metric ton of CO₂ equivalent reduced or removed, issued after a project meets defined standards and verified by an accredited body.

### How it works

Projects — reforestation, methane capture, renewable energy, direct air capture — undergo methodology review and third-party verification. Approved credits enter registries where buyers retire them against corporate climate claims.

Markets split roughly into:

- **Compliance markets** — government cap-and-trade systems with mandatory participation
- **Voluntary markets** — companies purchase offsets beyond legal requirements

Pricing varies by project type, permanence, and co-benefits. **Additionality** (would the reduction happen without credit revenue?) and **permanence** (will carbon stay stored?) dominate diligence debates.

Venture-backed climate companies may generate credits as core revenue or as a secondary stream from deployed assets.

Buyers increasingly demand registry-specific quality tiers and third-party ratings. Founders should treat credit issuance timelines as product milestones — verification delays directly push revenue recognition and project finance covenants.

Registry choice matters: credits issued under one standard may not trade in buyer programs aligned with another — locking in registry strategy early avoids stranded inventory.

### Why it matters

- **Founders:** Credit revenue can improve project finance but depends on registry approval and buyer trust. Build measurement and verification into product design early.
- **Investors:** Separate hype from durable demand. Low-quality credits face reputational backlash; regulatory shifts can reprice entire categories overnight.

### Common mistake

Equating any offset purchase with credible climate impact. Buyers and regulators increasingly scrutinize credit quality — "cheap tons" may not sustain pricing or survive reputational audit.

## FAQ

### What is a carbon credit in simple terms?

It is a proof token that one ton of CO₂ was avoided or removed — companies buy credits to offset emissions they cannot eliminate yet, and project developers sell credits to fund their work.

### Why does carbon credit matter?

For climate founders, credits can be a revenue line — if projects meet quality standards. For investors, credit markets involve regulatory, reputational, and verification risk beyond typical SaaS metrics.
