ESG and sustainability software supports carbon accounting, sustainability reporting under the CSRD and the European Sustainability Reporting Standards, supply-chain due diligence and ESG data management. Organisations use it to collect emissions and supplier data, calculate footprints, answer customer and investor questionnaires and prepare reports that others will verify.
Supplier lists, energy use, production volumes and emission factors reveal how a business operates, and reports are meant to be checked, so the audit trail must stay traceable for years. The rules are still moving: the Commission has simplified parts of the CSRD and its standards, so tools must follow changes in scope and datapoints. A platform that keeps your calculation methods, emission-factor libraries or supplier data in a proprietary format makes later audits and switching hard.
In a European option, check support for the standards' datapoints and for machine-readable output, transparency about calculation methods and emission-factor sources, role-based access for suppliers and auditors, and EU hosting. Look at whether supplier data collection works through standard templates, and whether data and calculation history export in open formats, so that earlier reporting years remain reproducible after a switch.
