CarbonTool vs Hedgehog Carbon Platform

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.

Hedgehog Carbon Platform is web software for organizations calculating business emissions and preparing reports. It records Scope 1, 2, and 3 emissions from operational data according to the GHG Protocol. Users enter data manually, upload sheets for AI analysis, and ask an AI guide about data sources; human GHG experts are also available for in-app support. The platform accommodates multiple business locations and sites, with dashboards spanning entities and activities, and role-based invitations for data owners, auditors, and managers. Reporting is presented for the GHG Protocol, PPN 006, and the CO2-Prestatieladder. Hedgehog says it can provide needed emission-factor databases and supports a range of industries, including construction materials, manufacturing, retail, health services, finance, and professional services. Its security measures include HTTPS, OAuth2, role-based access controls, and daily data backups; the company says its information security management system complies with ISO 27001 standards. A free plan covers five emission sources, one user, and one entity. Pro starts at €100 per month, billed annually; Expert starts at €1200 per month.
