Sustainability Reporting Software UK: Types and Frameworks

What sustainability reporting software does

One dataset, several disclosures

Sustainability reporting software collects environmental, social and governance data, turns it into the metrics a framework asks for, and produces a disclosure with the evidence behind each figure.

For a UK company the frameworks are UK SRS S1 and S2, the ISSB standards they are built on, SECR in the directors’ report and, for groups with an EU footprint, CSRD and the ESRS.

GRI and CDP sit beside them as voluntary frameworks that customers, investors and lenders ask for.

The emissions number underneath is built by carbon accounting software, and the regime-by-regime output is covered on carbon reporting software; this page is the map above both.

The instruments cited here specify what must be disclosed, not which tool discloses it, so the useful question is which duties you carry and whether one dataset can serve them all.

The four types

Four starting points, one crowded market

Sustainability reporting software comes in four types, distinguished by where the product started rather than by what it now claims to cover.

Carbon accounting platforms are strongest on the emissions inventory; ESG reporting platforms on framework mapping and drafting; EHS-heritage suites on site data and operational controls; enterprise-suite modules on the finance and procurement data already in the host system.

Each type is weakest where it started furthest from, so the type tells you which tests to run hardest.

Read the detailed guidance and references

The grouping is this site’s reading of the categories in its vendor registry, and a vendor can carry several; the counts beside this overlap and do not sum to 73.

The enterprise-suite products in the registry are Microsoft Sustainability Manager, Oracle Fusion Cloud Sustainability, Salesforce Net Zero Cloud, SAP Sustainability Footprint Management, ServiceNow Operational Sustainability Management and Workday (supplier sustainability), each described on its profile in its owner’s words.

This site’s reading of each type; it is not an assessment of any product in it.
Type	Started from	Test hardest
Carbon accounting platform	Activity data × emission factors, by scope	Materiality, narrative drafting and non-climate topics
ESG reporting and disclosure platform	Framework mapping, drafting and approval	Factor versions, Scope 3 method by category, restatement
EHS-heritage suite	Incidents, permits, site environmental data	Group consolidation on the accounts’ entity, and disclosure output
Enterprise-suite module	ERP, CRM or workflow data already held	Emission factor depth, Scope 3 methods and the cost of the host licence

The measurement layer and its tests are set out in depth on GHG reporting software, against the GHG Protocol’s Corporate Standard.

Where the
product started

Carbon accounting platforms

Built around the greenhouse gas inventory, then extended to disclosure.

60 vendors in this site’s registry carry this category.

ESG reporting and disclosure platforms

Built around framework mapping, drafting, review and sign-off.

51 vendors carry this category.

EHS-heritage suites

Built for environment, health and safety compliance, with sustainability reporting added.

11 vendors carry this category.

Enterprise-suite modules

Sustainability products from companies selling a wider ERP, CRM or workflow platform.

6 products in the registry, grouped by this site.

Which type first

Find the failing layer before choosing a type

Decide which layer is failing — data, measurement or disclosure — before deciding which type of product to look at.

If the data is missing, no platform fixes it; the first purchase is owners for each feed and a settled boundary.

If the number cannot be defended, the gap is measurement, and a carbon accounting platform is the natural place to start.

If the number is sound but the report is not, the gap is disclosure, where ESG reporting platforms and enterprise-suite modules compete.

The three questions beside this decide it in under a minute and name no product.

Which layer is your problem?

Do you hold meter, fuel and travel data for every entity in your boundary, by site and month?YesNo, or not for every site

Three yes/no questions; the first “no” decides.

Nothing is stored or sent.

Framework coverage

Six frameworks, three kinds of obligation

The frameworks a UK reporter maps to fall into three kinds: statute (SECR, and CSRD for an in-scope EU entity), listing rules on a comply-or-explain basis (UK SRS for listed companies), and voluntary frameworks (UK SRS for everyone else, GRI and CDP).

Under the FCA’s PS26/19, listed companies in UKLR 6, 14, 15, 16 and 22 report against UK SRS on a comply-or-explain basis for periods beginning on or after 1 January 2027; nothing in UK SRS is mandatory for them.

UK SRS S1 and S2 remain voluntary for every other entity, as published by the Department for Business and Trade on 25 February 2026.

What vendors say they cover

CSRD on most vendor pages, UK SRS on few

Of the 73 vendors in this site’s registry, 62 mention CSRD or ESRS on the pages read, 35 mention the ISSB or IFRS S2, and only 8 mention UK SRS.

17 mention SECR, 6 mention PPN 006 and 3 mention ESOS, the UK duties a UK company is most likely to carry today.

The gap is a feature of where the market was built, not proof that products cannot do it: UK SRS is close to the ISSB standards, and SECR is a short list of lines.

It does mean that a UK buyer should not infer UK coverage from an EU or ISSB claim, and should ask to see each UK output produced on its own data.

The regime-by-regime claims, vendor by vendor and in their own words, are tabulated on the carbon reporting software hub.

What each UK duty asks the software to output

Tick your duties, read off the outputs

Each UK duty asks the software for a different output, and the checklist beside this builds the list from the duties you tick, each output cited to its provision.

SECR applies to quoted companies and to large unquoted companies and LLPs; a company is large only when it exceeds two of £36m turnover, £18m balance sheet and 250 employees, with the exempt side framed as “not more than” and judged over two consecutive years after the first.

ESOS Phase 4 qualification is assessed on 31 December 2026 and compliance is notified by 5 December 2027, under the Environment Agency’s Phase 4 guidance.

PPN 006 is a procurement policy binding contracting authorities, not a legal duty on companies; the Technical Standard names the five Scope 3 categories.

The UK CBAM is a tax on imports in five sectors — aluminium, cement, fertiliser, hydrogen, and iron and steel — from 1 January 2027 under Finance Act 2026 Part 5; a vendor’s “CBAM” claim may refer to the EU mechanism, so ask which.

The SECR lines alone, and the tools that produce them, are on SECR reporting software; the ESOS evidence pack and MESOS are on ESOS software.

UK SRS and the ISSB, in software terms

Four requirements that decide the architecture

Four requirements in UK SRS and the listing rules decide how a reporting platform has to be built, more than any feature list.

UK SRS S1 ¶20 ties the sustainability report to the same reporting entity as the financial statements, so the platform’s entity model must match the consolidated group.

IFRS S1 ¶64 asks for the disclosures at the same time as the related financial statements and for the same period, and UK SRS S1 carries the same timing section (¶¶64–69), which puts the platform on the accounts’ close timetable.

UK SRS S2 ¶29(a) asks for gross Scope 1, 2 and 3 emissions measured under the GHG Protocol, with location-based Scope 2.

The listing rule then asks a company that does not make a disclosure to say what is missing, why and what it is doing about it, under UKLR 6.6.6R(7A) and (7B) as made by PS26/19.

Read the detailed guidance and references

UK SRS S1 and S2 are the UK versions of IFRS S1 and S2, and the government’s consultation response maps each difference in Annex A without giving a count.

The SASB reference becomes permissive in the UK: “shall refer to and consider” becomes “may” at UK SRS S1 ¶¶55(a) and 58(a), so a platform need not force SASB metrics on a UK reporter.

The effective date of 1 January 2024 belongs to the ISSB’s standards, issued in June 2023, and does not apply to UK SRS, whose closing appendices are renamed “Application and transition”.

UK SRS S2 is based on IFRS S2 as amended by the ISSB in December 2025, so a platform’s S2 template should carry those amendments.

New or amended ISSB standards do not apply in the UK until they pass the UK’s endorsement process, as the FRC’s FAQs put it, so an ISSB update in a product is not a UK SRS update.

Materiality under UK SRS is single (financial): information is material if it could reasonably be expected to influence the decisions of primary users of general purpose financial reports, under S1 ¶18.

CSRD, the ESRS and the materiality lenses

Single, double or impact: one dataset, three questions

A platform serving UK SRS and the ESRS from one dataset has to hold two different materiality assessments and keep them apart.

CSRD reaches a UK group through an EU subsidiary or listing that exceeds both 1,000 employees and €450m net turnover, for financial years beginning on or after 1 January 2027, as narrowed by Omnibus I in the consolidated Accounting Directive.

The revised ESRS were published as Delegated Regulation (EU) 2026/1563 on 21 September 2026, enter into force on 10 November 2026 and apply to financial year 2027.

Read the detailed guidance and references

The Directive also sets a third-country route: a non-EU parent with more than €450m of EU turnover, and an EU subsidiary or branch above €200m.

A platform built before 2026 may still carry the 2023 ESRS; ask which delegated act its templates implement, and whether its datapoint list is the revised one.

The double materiality assessment as published is in ESRS 1 Chapter 3; the method and its traps are set out on double materiality, and the standards on the ESRS.

A vendor’s CSRD claim may have been written for the 2023 standards and the pre-2026 scope, so date every claim you read.

GRI and CDP

The voluntary frameworks customers actually ask for

GRI and CDP are voluntary, but they are the frameworks customers, investors and lenders most often ask a UK company to answer, so a platform is usually judged on them as well.

The GRI Standards apply impact materiality: under GRI 3, material topics are an organisation’s most significant impacts on the economy, environment and people.

GRI and EFRAG’s interoperability index treats an ESRS reporter as reporting “with reference to” the GRI Standards, not “in accordance with” them, and it was written for the 2023 ESRS.

CDP scores responses from D- to A, and its 2026 final response deadline falls in the week commencing 26 October 2026.

What each GRI standard asks for is on the GRI Standards; a CDP response is a questionnaire in CDP’s own modules, so test that the platform exports to it rather than describing a mapping.

Assurance and the evidence trail

Assurance is optional; the statement about it is not

No UK rule requires a company to have its sustainability reporting assured, but a listed company that does obtain assurance must say so.

Under UKLR 6.6.6R(8)(d), as made by PS26/19, it states who provided the assurance, which disclosures were assured and which standards were used.

The FRC issued ISSA (UK) 5000 on 12 November 2025 for voluntary use, effective for periods beginning on or after 15 December 2026.

A platform either keeps the evidence chain as the work happens or someone rebuilds it later for the practitioner, and the second costs more; the UK position in full is on sustainability assurance.

Cost

Most prices are unpublished; build your own three-year figure

Most sustainability reporting software vendors do not publish a price.

Of the 73 in this site’s registry, 9 publish a figure on their own pages and 4 publish a free tier or plan; the rest are recorded as Enterprise level · TBD, read 11 October 2026 and 30 September–1 October 2026.

The licence is rarely the largest cost over three years: implementation, added entities after an acquisition, integrations and the cost of getting your data out can each exceed it.

The worksheet beside this totals your own written quotes and holds no vendor’s price.

For an enterprise-suite module, ask whether the host licence is a prerequisite, because that cost sits outside the sustainability quote.

Choosing without a ranking

Six demonstrations that cross the frameworks

Choose sustainability reporting software by the outputs your duties require, demonstrated on your own data, not by a list someone else has ordered.

Each question beside this comes from a provision and says what a passing answer looks like; ask every vendor the same ones in writing.

The first is the most revealing: one stored figure, two outputs, and the working behind both.

Comparisons that rank for these searches are often published by a vendor that appears in its own table, and analyst placings are the analyst’s statement on its own date.

The wider ESG reporting market, and why its published comparisons score frameworks a UK company may not file, is on the ESG software comparison.

The words buyers use

Sustainability software, platform, tool — one market, several names

Sustainability software is the widest term, and includes energy management, supplier engagement, product footprint and target-tracking tools that never produce a report.

Sustainability reporting software, or a sustainability reporting platform, is the part that ends in a disclosure, judged on materiality, framework mapping, the reporting entity and the evidence.

Sustainability management software and corporate sustainability software describe the same products from the operations side: targets, actions and data owners.

A sustainability reporting tool usually means something narrower, such as a calculator or a single-framework template, which can be enough for a first SECR statement.

ESG software is the same market named for the three pillars an investor scores.

This site has tested no products

Frequently asked

Sustainability reporting software, answered

What is sustainability reporting software?

Software that collects environmental, social and governance data, turns it into the metrics a framework asks for, and produces a disclosure with the evidence behind each figure.

In the UK the frameworks it is asked to serve are UK SRS S1 and S2, SECR, and for some groups CSRD and the ESRS, with GRI and CDP as voluntary frameworks that customers and investors request.

What is the best sustainability reporting software?

This site does not rank products and has tested none, so it names no best.

Start from your duties: list the outputs you owe (SECR lines, a UK SRS report, an ESRS statement, a CDP response), turn each into a test, and ask every vendor to show it on your own data.

The demo questions on this page are built from the provisions that create each output.

What is the difference between sustainability software and sustainability reporting software?

Sustainability software is the wide term: it includes tools for energy management, supplier engagement, product footprints and target tracking that never produce a report.

Sustainability reporting software is the part that ends in a disclosure, which is why it is judged on materiality, framework mapping, the reporting entity and the evidence trail.

Is sustainability management software the same thing?

Mostly the same products described from the operations side: targets, action plans and data owners rather than the published report.

A buyer reporting under UK SRS or SECR still needs the disclosure layer, so test that a management platform can produce the output you owe, on the accounts’ entity and period.

Which sustainability reporting platforms support UK SRS?

In this site’s registry, 8 of 73 vendors mention UK SRS on the pages read, against 62 that mention CSRD or ESRS.

A mention is a vendor’s own statement, not evidence of capability, and its absence is not evidence that a product cannot do it.

Ask for the UK SRS S2 ¶29(a) metrics and the UKLR 6.6.6R explanation drafted on your own data.

If a platform supports ISSB, does it support UK SRS?

Largely, but not automatically.

UK SRS S1 and S2 are the UK versions of IFRS S1 and S2 with UK amendments: the SASB reference becomes permissive, the effective dates are removed, and the relief periods are untimed.

New or amended ISSB standards apply in the UK only after UK endorsement, so an ISSB update in a product is not a UK SRS update.

Can one platform report against UK SRS and CSRD?

One dataset can feed both, but the two apply different materiality lenses: UK SRS applies single (financial) materiality, judged by the information needs of primary users of general purpose financial reports, while the ESRS apply double materiality.

Ask the vendor to hold the two assessments separately and label which disclosures each one decided.

Do I need sustainability reporting software for SECR?

Not necessarily.

SECR asks for a short set of lines in the directors’ report: energy use in kWh, emissions from gas, electricity and transport fuel, an intensity ratio, the methodology and comparatives.

A company is in scope as large only when it exceeds two of £36m turnover, £18m balance sheet and 250 employees; for many, a controlled spreadsheet carries it.

Which frameworks should a UK sustainability reporting tool cover?

The ones you owe or are asked for, in that order.

For a listed company in UKLR 6, 14, 15, 16 or 22, that is UK SRS on a comply-or-explain basis for periods from 1 January 2027; for a quoted or large company, SECR; for a large undertaking, ESOS; for a group with an in-scope EU entity, CSRD and the ESRS; then GRI and CDP where customers or investors ask.

What sustainability reporting tools suit a small business?

Often a lighter tool than the market sells: Scope 1 and 2 from fuel and electricity, answers to customers’ supplier questionnaires and, where it bids for in-scope central government contracts, a PPN 006 Carbon Reduction Plan.

In this site’s registry, 13 vendors say on their own pages that they serve small or mid-sized businesses.

How much does sustainability reporting software cost?

Most vendors do not publish a price.

Of the 73 vendors in this site’s registry, 9 publish a figure on their own pages and 4 publish a free tier or plan; the rest are recorded as Enterprise level · TBD.

Ask for a written three-year cost that includes implementation, added entities, integrations and the cost of exit.

Is corporate sustainability software different from ESG software?

The words describe the same market.

“ESG” stresses the three pillars an investor scores; “corporate sustainability” stresses the company’s own reporting and targets.

What matters for a UK buyer is the same either way: which outputs the product produces, from which data, with what evidence.

Has the sustainability software market consolidated?

Yes.

Since February 2025 the owners’ own announcements record 11 ownership changes among vendors in this site’s registry, from Ecologi acquiring Net Zero Now to the Greenly–Normative merger announced in September 2026.

Check who you would be contracting with and what a change of owner does to your data and contract.

Are sustainability reporting software reviews worth reading?

Read who wrote them first.

Several comparisons that rank for these searches are published by a vendor that appears in its own table, and analyst placings are the analyst’s statement on its own date.

This site publishes no reviews and has tested no products; it lists what each vendor says and the provisions to test against.
