Comparing carbon accounting software: a guide for businesses
Direct answer
Carbon accounting software calculates your organisation's carbon footprint: it gathers activity data, links it to emission factors and totals the emissions across scope 1, 2 and 3. When comparing carbon accounting software, look at the calculation method under the GHG Protocol, current Dutch emission factors, connections to your source systems and a verifiable audit trail.

Comparing carbon accounting software: scattered information versus Energy Intelligence
More and more businesses have to report their CO2 emissions with proper evidence, towards clients, banks or under the European CSRD. A facility manager often starts in a spreadsheet with invoices for gas, electricity and fuel. As long as there are only a few entries, that works. But once you have to cover multiple sites, suppliers and the entire value chain, manual work becomes error-prone and hard to verify. Carbon accounting software takes over that calculation and records the origin of every figure.
- The software converts raw activity data, such as litres of fuel or kilowatt-hours, into CO2 emissions per scope using emission factors.
- Under the CSRD, your greenhouse gas reporting must align with the GHG Protocol and standard ESRS E1, and the information is subject to an assurance engagement.
- Compare packages on method, currency of the emission factors, data sources, audit trail and export to reporting formats, not on price alone.
Insight
Traditional approach
Information is scattered across portals, documents, invoices or separate spreadsheets.
Modern approach
Data, context and interpretation are brought together into a clear decision picture.
Decision-making
Traditional approach
Choices are made based on averages, assumptions or occasional analyses.
Modern approach
Scenarios, KPIs and current measurement data make the trade-off more concrete and repeatable.
Follow-up
Traditional approach
Actions often stay non-committal or disappear into separate reports.
Modern approach
Follow-up actions, monitoring and reporting are linked to the same energy data.
What does carbon accounting software do?
The software translates what your organisation consumes into CO2 emissions. First you gather activity data: natural gas in cubic metres, electricity in kilowatt-hours, fuel in litres, purchased goods and services. The software links each entry to an emission factor, a figure that indicates how much greenhouse gas one unit of consumption causes. It then calculates the emissions and organises them according to the GHG Protocol into three scopes. Scope 1 is direct emissions from your own sources, scope 2 is purchased electricity, heat or steam, and scope 3 covers the indirect emissions in your value chain. Finally, the software produces reports and stores, per figure, the origin and the factor used, so that an auditor can follow your calculation.
- Gather activity data from invoices, meters and administration.
- Link each entry to an emission factor and convert it into CO2.
- Organise the emissions into scope 1, 2 and 3 under the GHG Protocol.
- Generate reports with an audit trail per figure.
- Often calculate scope 2 two ways: location-based and market-based.
When does a spreadsheet no longer suffice?
A spreadsheet works as long as your footprint is small and manageable. Once the number of sites, energy contracts and suppliers grows, manual entry becomes error-prone and hard to repeat. Scope 3 in particular, the emissions in your value chain, calls for many data sources and a consistent method. If you report under the CSRD, a hard requirement is added: your sustainability information must align with the GHG Protocol and standard ESRS E1, and it is checked through an assurance engagement. An auditor wants to see where each figure comes from and which factor was used. A loose worksheet without recorded origin usually does not meet that bar, whereas software has that traceability built in.
- Multiple sites, contracts and suppliers make manual work error-prone.
- Scope 3 requires many data sources and a consistent method.
- Under the CSRD, reporting must align with the GHG Protocol and ESRS E1.
- An assurance check requires a traceable audit trail per figure.
- Annual repeatability matters more as the organisation grows.
What do you compare packages on?
Start with the calculation method. Does the package follow the GHG Protocol with a clear scope breakdown, and can you see which assumptions it makes? Then look at the emission factors. For the Dutch situation, the list on CO2emissiefactoren.nl is the reference, an initiative involving Milieu Centraal, SKAO and the national government that is updated annually. Check whether the package uses those current, Dutch factors for electricity, natural gas and heat. Next, consider data sources and connections: can the software pull data from your energy, accounting or procurement systems? Assess the audit trail: does it record the source and the factor used for each figure? Finally, look at export: can you write the results to ESRS formats and take your own data with you without trouble?
- Method according to the GHG Protocol, with transparent assumptions.
