Carbon accounting software helps businesses track, measure, and report their greenhouse gas (GHG) emissions. It automates data collection, calculates emissions across Scopes 1, 2, and 3, and provides tools for compliance and sustainability planning.

Carbon accounting involves gathering data on energy use, transportation, waste, and supply chain activities. Using emission factors, you calculate GHG emissions in CO₂-equivalents, typically broken down into direct (Scope 1), indirect (Scope 2), and value chain (Scope 3) emissions.

It depends on where you're based, and the size / profile of your business. For example, Carbon accounting is mandatory for large UK companies under the Streamlined Energy and Carbon Reporting (SECR) framework. Businesses meeting size thresholds must report their emissions and energy use in annual filings.

In addition, many businesses must report carbon data to clients (e.g. as part of a tender) or to their investors (as part of their portfolio ESG strategy).

Look for software that aligns with your industry, integrates with your data sources, and supports recognised reporting standards (e.g., GHG Protocol). User-friendly interfaces, scalability, and cost-effectiveness are also key considerations. Seedling for example is great for businesses up to 2000 FTEs looking to calculate their carbon footprint using software and expert support.
