Scope 3 emissions accounting in supply chains: Ground reality across SME vendors

Scope 3 carbon footprint tracking accounts for the largest share of corporate emissions, yet it is the hardest to measure. Supply chains involving SME vendors rarely have resources for ESG calculations. CarbonFlow bridges this gap with structured supplier data ingestion pipelines.

Large enterprises can invite SME vendors to submit raw logistics and utility data easily without complex environmental metrics definitions.

Scope 3 collection cadence

• Establish direct input templates for vendor travel, fuel, and logistics.
• Map vendor data to standardized GHG emission factor profiles.
• Track progress across supply chain segments on a unified dashboard.
• Export audit logs to support your primary BRSR filings.

Best practices

• Avoid asking vendors to calculate emissions; collect raw activity values.
• Maintain transparent audit logs for all carbon emission factor mappings.
• Review supply chain targets quarterly to note abatement achievements.
