Hedgehog Carbon Platform

Hedgehog Carbon Platform is a web service for building operational greenhouse-gas inventories and related reports. It suits organizations coordinating emissions data across several sites or contributors, particularly those that want access to carbon-accounting specialists. Its scope coverage and collaborative controls are substantial, but the free tier is intended for a very small pilot and Pro commits you to annual billing.

Overview

Hedgehog records Scope 1, Scope 2 and Scope 3 emissions from operational data under the GHG Protocol. Collection is manual, so the platform organizes and assists the work rather than replacing the need to gather invoices, activity figures and other source data. An AI guide answers questions about data sources and can analyze uploaded data sheets, giving a team a practical starting point for an inventory.

Reporting supports the GHG Protocol, PPN 006 and the CO2-Prestatieladder. Workspaces can cover multiple business locations and sites, with dashboards spanning entities and activities. Invited colleagues can receive data-owner, auditor or manager roles, which is useful when responsibility for gathering and checking figures is distributed. Hedgehog says it can provide the emission-factor databases required by users and supports industries including construction materials, manufacturing, IT and consumer electronics, plastics and recycling, fashion, retail, health and funeral services, finance and professional services.

Key features

• AI and expert assistance: Chat-based guidance and spreadsheet analysis can reduce uncertainty during initial data collection. Human GHG experts are available in-app, while Expert adds a dedicated Hedgehog expert; this is more valuable for teams without established internal carbon expertise than for specialists who only need a calculation ledger.
• Multi-entity collaboration: Location- and site-based workspaces, cross-entity dashboards and three permission roles support a review process rather than a single-user spreadsheet.
• Reporting orientation: Coverage of three scopes and the named reporting frameworks makes the service relevant to organizations preparing formal disclosures or procurement-related carbon documentation.
• Security controls: Hedgehog says its information-security management system complies with ISO 27001 standards. Traffic uses HTTPS, access uses OAuth2 and role-based controls, and stored data is backed up daily.
• Manual input and limited integrations: Supplier engagement is supported and emission factors can come from both options offered by the platform, but Hedgehog says it currently has few integrations with other software. Teams expecting automated synchronization should therefore look elsewhere or plan additional manual work.

Pricing

Free is suitable for one person validating the workflow on one entity, but five sources and one user make it unsuitable for a growing inventory. Pro removes the source ceiling and adds locations or users, making it the practical tier for a working team; its annual billing is the main commitment, and each added location or user raises the monthly cost. Expert is aimed at organizations buying continuing specialist involvement, with the advantage of monthly cancellation that Pro does not provide. There is no free trial.

Platforms

Hedgehog Carbon Platform runs on the web. That suits distributed teams and invited reviewers, provided their work can be done through a browser; no desktop platform is offered.

Who it's for

Choose Hedgehog for a multi-site organization that needs Scope 1–3 accounting, defined review roles and reporting aligned with the GHG Protocol, PPN 006 or the CO2-Prestatieladder. It is also a sensible fit when staff want AI guidance plus access to human GHG expertise. A solo user with only a handful of sources can begin on Free. Businesses dependent on deep accounting-system integrations, or those wanting automated rather than manual collection, are less well served.

Pros and cons

• Pros: Scope 1–3 coverage; AI sheet analysis alongside human support; multi-site dashboards and role-based collaboration; support for supplier engagement and multiple reporting frameworks; HTTPS, OAuth2, role-based access and daily backups.
• Cons: Free is limited to five sources, one user and one entity; Pro is billed annually; extra users and locations cost €15 each per month; integrations are currently few; data collection remains manual.

Alternatives

• Carbonfact is the better choice for supplier-facing environmental-data exchange and product LCAs, with a free supplier plan and API/web access.
• CarbonInk suits someone wanting a free, no-account, no-cloud desktop tool for macOS or Windows rather than a collaborative web workspace.
• CarbonTool is worth considering for a 30-day full-access trial and a Scope 1+2 starter measurement before committing.
• EcoReko offers a free web tier with one user, one site, Scope 1–3 tracking, an emissions-factor library and a static dashboard.
• Greenio is an alternative for API/web users seeking unlimited data entry, four PDF reports per year and AI recommendations on its free plan.
• Persefoni provides a free self-service option for a single user with unlimited assets and historical reporting years.
• Vaayu is an alternative whose paid pricing is available on request.
• Carbonstop Ccloud is a paid enterprise option available for self-hosted or web deployment.

Verdict

Hedgehog Carbon Platform is a strong match for organizations that need structured Scope 1–3 accounting across sites and want expert help as well as AI assistance. Pick it for its collaborative workspaces, reporting coverage and dedicated-support path. Look elsewhere if automated integrations, desktop operation or a generous free tier matters more than guided, manually collected accounting.
