Top 7 carbon accounting software tools for managing emissions data
Carbon accounting software is getting more common because more companies are being asked (by regulation, customers, investors, and suppliers) to measure and report emissions across Scope 1, 2, and often Scope 3.
Most teams want the same thing: reliable numbers, a clear method behind them, and outputs you can defend in an audit (without living in spreadsheets).
Below is a quick, practical look at 7 tools that help collect emissions data and turn it into reporting.

What to look for when choosing Carbon Accounting software
A simple checklist that saves time:
- Method + credibility: Does it align with the GHG Protocol approach, and can you explain the calculations?
- Scope 3 reality check: Can it handle supplier data, categories, and estimates without turning into chaos?
- Audit readiness: Are there logs, review flows, and traceability from input → output?
- Integrations: Can it pull from ERP/finance/procurement/energy systems without constant manual work?
- Effort vs value: Implementation time, internal ownership, vendor support, and total cost.
