Comparison Table
Plan A
SMBCarbon accounting and decarbonization platform for automated emissions measurement and reduction planning.
Input-to-result traceability links each emissions number to the specific source rows and factor mapping used to compute it.
Plan A’s emissions analytics flow centers on structured inputs for activity data and emission factor mapping, then produces calculated outputs tied to a traceable basis for each result. It supports common reporting workflows used for CSRD-related disclosures and CDP-style reporting, using category-specific assumptions and consistent unit handling. Integration depth is a key strength, because recurring ingestion of upstream datasets reduces manual CSV reshaping and version drift.
A concrete tradeoff is that deeper automation depends on having clean source fields for location, fuel type, supplier or spend taxonomy, and time granularity. Teams typically use Plan A when emissions accounting needs to connect to existing operational systems and when multiple stakeholders must review the same calculation logic before publication.
- +Calculation outputs stay tied to the inputs used for each modeled result
- +Integrations reduce recurring rebuilds of emission factors and mapping spreadsheets
- +Scenario inputs support faster what-if modeling across organizational boundaries
- +Workflow controls support repeatable review cycles before disclosure exports
