CarbonTool builds Scope 3 Category 1 inventories using either supplier-specific emissions data or spend-based proxies, depending on data availability. As suppliers provide actual data, the inventory shifts from estimates to verified figures. The platform tracks this progression and flags where primary data collection would most reduce uncertainty, so engagement effort is prioritised where it matters.

Yes. CarbonTool supports product carbon footprint calculation aligned with ISO 14067 and the GHG Protocol Product Standard. You can allocate supply chain, logistics, packaging and use-phase emissions to individual SKUs or product categories. This is increasingly required by buyers, regulators and green claims frameworks across European markets.

CSRD requires retailers to disclose Scope 1, 2 and 3 emissions with audit-level traceability, including double materiality assessment and value chain data. CarbonTool structures all three scopes to the required standard, maintains data provenance back to source and produces disclosures formatted to the European Sustainability Reporting Standards, without needing a consultant to translate between your data and the framework.

CarbonTool provides a structured supplier data request workflow that makes it straightforward for suppliers to submit activity data such as energy use, transport records, material volumes, without requiring them to have their own carbon accounting system. Where supplier data is unavailable, spend-based or physical-unit proxies maintain inventory completeness while primary data collection is underway.
