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”).
You can choose on the product page whether these details - apart from the CO₂ amount - are 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.
