📌 In this article, ESG specialist Christian Clinciu, compares carbon accounting software tools to help organizations choose software to account scope 1–3 carbon offset and become audit-ready.
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.
