Carbon credit · methane reduction
A credit for methane reduction.
Composting organic waste (Biowaste) prevents methane from forming. This credit represents the verified emission reduction achieved through that work.
What it represents
1 credit
C-CARB.CH4
1 tCO₂e
One metric ton of verified CO₂-equivalent emission reductions.
From material to credit
The outcome begins with real work.
The material is tracked and composted. The evidence passes through verification rules before issuance.
The material has a history
The MassID records the source, mass and movement of the Biowaste. This chain of custody connects the material to the operation's evidence.
Explore a MassIDTreatment prevents methane
An accredited facility composts the Biowaste. Weighing, delivery and treatment are documented throughout the operation.
Explore Biocomp PindoramaThe evidence passes through the rules
The BOLD Carbon CH₄ framework defines the criteria and parameters used to verify the material and calculate the emission reduction.

A GasID records the verified emission reduction. The amount of C-CARB.CH4 issued corresponds to the outcome supported by the certificate.

GasID #41 supports the issuance of 0.296631 C-CARB.CH4.
What each credit represents
One origin. Different outcomes.
The same material can support a recycling outcome and a climate outcome. Each credit has its own unit and verification.
Buying credits funds recycling work
On Carrot's platform, purchased credits are automatically and permanently removed from circulation once the order is complete. You can follow the outcome on the public purchase page.

Issuance of C-CARB.CH4 matches the outcome recorded in a GasID. Credits allow fractions and are transferable within the protocol.
The protocol supports purchase and retirement as separate operations. In Carrot’s current purchase flow, credits are retired in the same transaction that records the purchase. No credit balance is delivered to the buyer’s wallet. The receipts record both operations.

The certificate supports credit issuance. The receipts identify the certificates and amounts used in purchase and retirement.
