Carboledger

Carboledger is a supply chain carbon accounting solution designed to help organisations calculate their Scope 3 emissions accurately, particularly those associated with purchased goods and materials. Many companies rely on spend-based estimates using industry averages, which provide a rough picture but cannot reflect actual differences between suppliers or capture the effect of reduction efforts. Carboledger addresses this limitation by collecting primary data from suppliers and combining it with product and process information to generate more precise, product-level emissions figures. Its approach is end-to-end, covering data collection, calculation, verification and reporting, with the aim of producing emissions data that is credible enough to support procurement decisions, customer disclosures and regulatory requirements, including those emerging in markets that increasingly demand carbon transparency across global supply chains. Over time, this allows companies to demonstrate genuine reductions achieved by their suppliers rather than relying solely on changes in spend or averaged industry factors.

Key features include a supplier portal that simplifies the collection of emissions and activity data, with guidance that helps suppliers without carbon accounting expertise provide useful information. Calculation engines apply recognised methodologies aligned with the Greenhouse Gas Protocol and life cycle assessment principles, while AI-assisted tools help map products and materials to appropriate emission factors. Dashboards identify emission hotspots by supplier, product and category, supporting prioritisation of decarbonisation initiatives and sourcing decisions. Reporting outputs support sustainability disclosures and product carbon footprint communication, and data can be shared with customers who themselves need supplier-specific information. The platform is cloud-based and is particularly relevant to manufacturers, industrial companies, consumer goods brands and exporters with complex, multi-tier supply chains, including those operating in India and other supply-heavy economies. Buyers should consider the level of supplier participation required to achieve the full benefit. A free version and free trial are available, and paid pricing starts from around USD 10,000.
