How our current method reads projects of this type

Versions of the official text these rules cover: 1.0 (31-03-2024)

What CarbonMeld reads

Integrity shown

Additionality: the methodology itself gives it (CSC v1.0 §2.2, p. 18). The project needs no test of its own. CM-F-ONCRA-CONSTRUCTION-STORED-CARBON-ADDITIONALITY

shown

Durability of the storage: the methodology sets rules for it (CSC v1.0, p. 3). CarbonMeld reads it in the project's documents. CM-F-ONCRA-CONSTRUCTION-STORED-CARBON-DURABILITY-MEASUREMENT

Link
shown

Sustainability of the feedstock: the methodology sets rules for it. CarbonMeld reads it in the project's documents. CM-F-ONCRA-CONSTRUCTION-STORED-CARBON-FEEDSTOCK-SUSTAINABILITY

Link

Set by the methodology or the programme, not assessed by our current method

not assessed

Leakage: the methodology sets rules for it in some cases (CSC v1.0, p. 17). Our current method does not assess it. CM-F-ONCRA-CONSTRUCTION-STORED-CARBON-LEAKAGE

Link
not assessed

Permanence and reversals: the methodology sets rules for it (CSC v1.0 §2.3, p. 19). Our current method does not assess it. CM-F-ONCRA-CONSTRUCTION-STORED-CARBON-PERMANENCE-REVERSAL

Link
not assessed

No legal requirement for the activity: the methodology sets rules for it (CSC v1.0 §2.2, p. 18). Our current method does not assess it. CM-F-ONCRA-CONSTRUCTION-STORED-CARBON-REGULATORY-SURPLUS

Not applicable to this type — never a gap in our current method

The criterion does not apply to this methodology. Our current method never counts it as a gap.

CM-N-GRID-EFGrid emission factor
CM-N-BUFFERBuffer pool
CM-N-FNRBFraction of non-renewable biomass (fNRB)
CM-N-USAGEUsage rate of the devices
CM-N-SAFEGUARDS-FPICSocial safeguards and consent of communities (FPIC)

The general rules apply as well. Read the general rules.
