Sustainability software for UK companies

Sustainability software is the broad category of platforms that collect, validate and report environmental, social and governance data so a company can disclose against the frameworks that apply to it1.

Where carbon reporting software focuses on greenhouse-gas emissions, sustainability software spans the wider picture: materiality assessment, social and governance metrics, transition plans, and the disclosure workflow that produces an assured report.

For UK companies the destination framework is UK SRS, the UK adoption of IFRS S1 and S24, with UK SRS S2 proposed mandatory for around 500 listed companies from 1 January 2027 under FCA CP26/52.

Below are the sustainability and ESG software platforms we'd shortlist for UK companies, from UK-native tools to global enterprise suites.

#1 is our editorial pick for UK SRS and SECR fit; the rest are ordered by how closely they fit a UK reporting journey rather than as a strict ranking.

Each links to a full platform review.

The right platform depends on which disclosure you are reporting against.

The guides below map the platforms above to the specific searches UK teams run.

Sustainability disclosure software

Sustainability disclosure software turns raw ESG data into a structured report against UK SRS, IFRS S1/S2 or CSRD, with the four-pillar architecture — governance, strategy, risk management, and metrics and targets4.

Enterprise suites such as Workiva and Cority specialise in the disclosure-and-controls layer, linking the report to the UK SRS reporting guidance and to assurance under ISSA (UK) 50003.

ESG management software (UK)

ESG management software goes beyond reporting to manage the underlying programme — materiality, targets, supplier engagement and stakeholder data across environmental, social and governance topics.

Greenly, Watershed and Normative are strong broad-ESG options; for UK-regulation alignment, our UK ESG reporting requirements guide sets out what these tools must deliver.

IFRS-compliant sustainability software

IFRS-compliant sustainability software produces disclosures aligned to IFRS S1 and IFRS S2, including Scope 1, 2 and 3 emissions to the GHG Protocol and mandatory climate scenario analysis4.

Because UK SRS is the UK adoption of IFRS S1/S2, a UK SRS-ready platform is effectively IFRS-aligned1.

CSRD and TCFD reporting software for UK listed companies

CSRD compliance software adds the EU's ESRS double-materiality requirements for UK groups with EU operations, while TCFD reporting software covers the framework that IFRS S2 now supersedes.

The leading suites map one dataset to TCFD, IFRS S2, UK SRS S2 and ESRS, so UK listed companies reporting across regimes avoid duplicate data collection.

Carbon reporting software is a focused subset of sustainability software — it measures and discloses greenhouse-gas emissions, while sustainability software adds the social, governance and disclosure-workflow layers1.

Most UK companies begin with carbon reporting software for SECR and expand to a full sustainability platform as UK SRS S1 scope grows.

If you would rather buy expertise than build it in-house, a sustainability consultancy is the alternative route to the same disclosures.
