How It Works: What Happens After You Buy a CO₂ Removal Credit

When you buy a CarbonConnect CO₂ Removal Credit, we carry out an official, certified process to retire your carbon removal in your name. This makes your impact permanent, transparent, and traceable.

Here’s what happens step-by-step:

Step 1 - Verification

Before anything is retired, each carbon removal unit has already been:

  • Measured & digitally tracked from field to soil

  • Verified under the Global Artisan C-Sink Standard

  • Added to CarbonConnect’s certified stock

Only verified carbon can be retired.

Step 2 - Retirement of the CO₂ you bought

After your purchase, CarbonConnect creates an official Retirement Transaction in the Global C-Sink Registry. This might take up to 2 weeks, since this is a manual process that will be checked by another 3rd party.

We register:

  • Your CO₂ amount (e.g., 100 kg)

  • Your name or company name

  • The retirement date

  • The reason for retirement (e.g., “Customer purchase”)

We register your CO₂ amount (e.g., 100 kg), your name or company name, the retirement date, and the reason for retirement (e.g., “Customer purchase”). All information will be visible on your .pdf certificate. 
You can choose on the product page whether these details - apart from the CO₂ amount - should also be shown transparently in the public registry or kept fully or partially anonymous.

Step 3 - Permanent & Non-Resellable

Once submitted:

  • A unique Retirement ID (e.g., GSCP1234) is generated

  • Your retirement appears in the Global C-Sink Public Registry

  • Your credit becomes permanently locked

  • It cannot be transferred or resold (preventing double counting)

Your climate action is now official and irreversible.

Step 4 - Official Certificate

You receive an official CSI Retirement File, containing:

  • Your beneficiary name

  • Amount of CO₂ retired

  • Retirement ID & date

  • Location of the C-Sink

  • A QR code leading to the public registry entry

You will receive this certificate via email

Step 5 - Public, Transparent, Verifiable

Every retirement features:

  • A publicly verifiable registry entry

  • Timestamped documentation

  • A unique, permanent Retirement ID

  • A direct link to the underlying verified biochar C-Sink Unit

Anyone can verify your impact at any time.
