In their own words
CarbonTool
CarbonTool is a carbon accounting platform for measuring, reporting and reducing Scope 1, 2 and 3 emissions. Its website describes one data backbone for CSRD, VSME, GRI, CDP and ISSB reporting. Organizations can enter data manually or use Excel/CSV, AI uploads, API connections or SAF-T imports. More than 200 templates provide emission-source methodologies, units and factors; listed factor databases include DEFRA, EPA, ecoinvent and ADEME. CarbonTool can track subsidiaries, sites or business units separately, then consolidate them into a group inventory. It supports reduction targets and scenario planning that compares impact, cost and return. Each data point can carry its source, unit, factor, quality level and audit trail. Free Starter access covers Scope 1 and 2; paid plans add Scope 3 across all 15 GHG Protocol categories. Starter access lasts 30 days without a credit card or auto-charge, and trial data remains for 90 days after access lapses. The service is built and hosted in the EU.
