Direct, verifiable on both sides, and settled in seconds rather than weeks. That is what a registry-to-marketplace connection should look like. Read the announcement: https://t.co/A6i1vWLinE

Where a carbon credit is issued and where it is sold have always been separate worlds, joined by email and spreadsheets.

Today EcoRegistry and Carbonmark connected their ledgers in both directions. 🧵

Every retirement is recorded on both platforms. Carbonmark issues a public certificate and the underlying credit is retired in EcoRegistry's system, so a sustainability report can point to proof on the underlying registry. Credits can go back to EcoRegistry at any time.

1/4 We compared seven carbon credit companies on the columns procurement actually asks about: minimum order, published fees, registry coverage, retirement proof.

Only two publish a number you can read without booking a call. 🧵

[Carbonmark @carbonmarkcom]

3/4 What we could confirm from public pages and docs:

-Carbon Trade Exchange publishes a fee schedule.
-Carbonplace names all 14 registries it connects to.
-Carbonmark publishes live per-tonne prices.

Everyone else quotes on request.

We wrote a full buyer's guide: live prices by project type, the six steps from browsing to certificate, and an honest look at marketplaces vs brokers vs buying direct.

Carbon offsets cost anywhere from $0.10 to $650 per tonne right now.

That 6,500x spread is not a scam signal. It is the most misunderstood fact in the carbon market.

Here is what actually drives it 🧵

[Carbonmark @carbonmarkcom]

What matters more than price: proof.

A real offset purchase ends in retirement, a permanent public record that one specific credit was used once, by you. On Carbonmark it is recorded on a public blockchain. Anyone can verify it.

Here's an example from @klimacarbonbot

[Carbonmark @carbonmarkcom]

@brian_armstrong We've collaborated with @KlimaDAO to release an x402 endpoint allowing agents to purchase and retire tokenized carbon credits. Check out our docs here: https://t.co/JrI62jAu6G

5/5 The live pricing layer is free to any caller, even ones that never transact. Machine-payable retirement gives the carbon market a demand channel it has never had: open at machine speed, around the clock. Full article: https://t.co/6c2U5e7LhJ

1/5 AI agents are starting to transact on their own: reading data, weighing options, and completing purchases within limits their operators set. Carbon markets now have an interface built for exactly that. 🧵

[Carbonmark @carbonmarkcom]

4/5 Every retirement is permanent and publicly verifiable on the @base blockchain with an onchain record plus a public certificate naming the beneficiary. Credits reached through the endpoint can only be retired, never withdrawn, transferred, or resold.
