What is sustainability software?
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 the ISSB's IFRS S1 and S24, with UK SRS S2 proposed mandatory for 515 of the roughly 600 affected listed companies from 1 January 2027 under FCA CP26/52.
Sustainability software, sustainability reporting software and sustainability disclosure software: how the terms differ
Sustainability reporting software is the term for platforms that capture environmental, social and governance data and turn it into a disclosure against UK SRS, IFRS S1/S2 or CSRD — the reporting-layer half of the broader sustainability software category.
In practice, sustainability software, sustainability reporting software and sustainability disclosure software are used almost interchangeably in the UK market, because they emphasise different parts of the same job rather than describing different tools1.
Sustainability reporting software is the term most UK teams search when they mean the reporting layer specifically — data capture through to a published report — while sustainability disclosure software describes the same output-facing capability from the other end: structuring governance, strategy, risk management, and metrics and targets into the four-pillar disclosure architecture4.
In practice, the platforms compared below serve all three descriptions at once — the comparison table and the by-reporting-need breakdown further down this page apply whichever term you searched.
What are ESG platforms, and how do they differ from carbon accounting software?
ESG platforms are sustainability software built to manage a company's full environmental, social and governance programme — materiality assessment, governance and social metrics, and disclosure across multiple frameworks — rather than measuring emissions alone, which is the narrower job carbon accounting software does1.
The distinction is scope, not competition.
Carbon accounting software — also called carbon management software or carbon reporting software — captures activity data, applies GHG Protocol emission factors, and produces Scope 1, 2 and 3 emissions reporting for SECR and UK SRS S2.
An ESG platform does that too, then adds the social and governance data, double-materiality assessment, and the four-pillar governance, strategy, risk management, and metrics-and-targets structure that UK SRS, IFRS S1/S2 and CSRD require4.
In practice the line blurs.
Enterprise suites such as Workiva and Cority build their ESG platform around the disclosure-and-controls layer described above, while several carbon-first tools add ESG modules as a customer's reporting scope grows from SECR into full UK SRS disclosure.
The comparison table below ranks all 17 platforms by how many disclosure frameworks each one covers — the clearest single measure of ESG-platform breadth against carbon-only depth.
The best sustainability software platforms
Below are the sustainability and ESG software platforms we'd shortlist for UK companies, from UK-native tools to global enterprise suites.

Sustainability software by reporting need
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.
The revised ESRS adopted on 3 July 2026 cut mandatory datapoints by more than 60%, with alignment to the ISSB standards named as an explicit objective — so the overlap between a UK SRS disclosure and an ESRS one is larger than it was under the 2023 standards5.
Sustainability software vs carbon reporting software
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.
| Capability | Carbon reporting software | Sustainability software |
|---|---|---|
| Primary focus | GHG emissions (Scope 1-3) | Full ESG + disclosure |
| Frameworks | SECR, GHG Protocol, UK SRS S2 | UK SRS S1+S2, IFRS, CSRD, TCFD |
| Materiality | Climate | Financial & double, across topics |
| Assurance | Emissions audit trail | ISSA (UK) 5000 across the report |
| Best for | SECR & climate reporting | Full UK SRS S1+S2 readiness |
Most UK companies begin with carbon management software for SECR and expand to a full sustainability platform as UK SRS S1 scope grows.
For the SECR end of that journey specifically — how to test a platform against the five artefacts Schedule 7 requires, rather than against a vendor's compliance claim — see SECR reporting software.
If you would rather buy expertise than build it in-house, a sustainability consultancy is the alternative route to the same disclosures.
The two pages share a roster because they genuinely are the same market's leading platforms — but they order it differently.
The carbon guide ranks on carbon-accounting depth; this page selects and orders on disclosure-framework breadth, counted from each platform's own framework list, and prints that count so you can check it.
Frequently asked questions
What is sustainability software?
Sustainability software collects, validates and reports environmental, social and governance (ESG) data so a company can disclose against frameworks such as UK SRS, IFRS S1/S2, CSRD and TCFD.
It typically covers carbon accounting, broader ESG metrics, materiality assessment, and audit trails for assurance.
What is the best ESG management software in the UK?
The best ESG management software for UK companies depends on scope: UK-native platforms like Climatise are built around UK SRS, SECR and ESOS; broad ESG suites such as Workiva, Watershed, Normative and Greenly cover wider sustainability topics and multi-framework reporting.
The comparison on this page ranks them by UK reporting fit.
Is there IFRS-compliant sustainability software?
Yes.
Most leading platforms support the four-pillar structure of IFRS S1 and S2 (governance, strategy, risk management, metrics and targets) and produce Scope 1, 2 and 3 emissions data to the GHG Protocol.
UK SRS is the UK adoption of IFRS S1/S2, so UK SRS-ready tools are effectively IFRS-aligned.
What software supports CSRD and TCFD reporting?
Enterprise sustainability suites such as Workiva, Watershed, Normative and Cority support CSRD (ESRS) and TCFD-aligned reporting alongside UK SRS.
TCFD is being superseded by IFRS S2, so platforms increasingly map the same data to TCFD, IFRS S2 and UK SRS S2.
Do I need separate carbon and sustainability software?
Not necessarily.
Carbon reporting software is a subset focused on greenhouse-gas emissions; broader sustainability software adds social and governance topics, materiality and disclosure workflow.
Many companies start with carbon accounting and expand to a full ESG/disclosure platform as UK SRS S1 scope grows.
