What is ESG reporting software?
Software that collects environmental, social and governance data, calculates the figures a framework asks for and produces the report, with an evidence trail behind each number.
In practice most products sold under the label are strongest on the environmental pillar, especially greenhouse gas emissions, and extend to social and governance indicators to different degrees.
What is the best ESG reporting software?
There is no single best platform, and any comparison that names one has chosen the scoring criteria that produce that answer.
For a UK company the deciding questions are which obligations it carries — SECR, ESOS, UK SRS if listed, PPN 006, CDP — and whether a platform produces the output each one requires.
This page gives a planner that turns your obligations into a capability list, and the vendors’ own claims to test against it.
Do I need ESG software?
Only when the outputs you owe have outgrown the way you produce them.
A single-entity company with a few sites, no Scope 3 obligation beyond travel and one framework can report from a spreadsheet.
Software earns its place when Scope 3 becomes material, when several entities need consolidating, when several regimes draw on one dataset, or when an assurer first walks the process.
What features matter for UK SRS?
Alignment with the financial statements — the same reporting entity, the same period, published at the same time — which is where standalone carbon tools struggle.
Then GHG Protocol measurement with current conversion factors, location-based Scope 2, Scope 3 by category with exclusions recorded, a split of Scope 1 and 2 between the consolidated group and other investees, and for listed companies a gap register the comply-or-explain statement can be written from.
Is UK SRS mandatory?
No. UK SRS S1 and S2 are voluntary standards published by the Department for Business and Trade on 25 February 2026.
Under the FCA’s final rules in PS26/19, listed companies in UKLR 6, 14, 15, 16 and 22 must report against them on a comply-or-explain basis for accounting periods beginning on or after 1 January 2027.
Nothing in UK SRS is fully mandatory, and no private-company threshold is proposed.
How much does ESG reporting software cost?
Most vendors do not publish a price, and the price moves with the number of entities, the boundary, the Scope 3 categories in play, the frameworks and the consulting bundled in.
Where a vendor publishes a price this site states it with a link and date; otherwise it reads Enterprise level · TBD.
Ask for a three-year cost including implementation, the annual uplift, the cost of adding an entity and the cost of exit.
What is the difference between sustainability reporting software and ESG reporting software?
They describe the same category from two angles.
Sustainability reporting software stresses structured disclosure against a named framework, with evidence trails and alignment with the accounts.
ESG reporting software stresses breadth across environmental, social and governance topics, including supplier questionnaires and board dashboards. <Link href="/environmental-reporting-software">Environmental reporting software</Link> is narrower again, usually the energy, emissions, waste and water surface that SECR and ESOS cover.
Is carbon accounting software the same as ESG reporting software?
No. Carbon accounting software is the measurement layer: it turns activity data into an emissions number.
ESG reporting software is the disclosure layer: it turns numbers into a filing tied to the reporting entity and period of the accounts.
Some platforms do both.
Buying a disclosure platform when the problem is missing meter data, or a measurement tool when the problem is an untraceable figure, is the same mistake in opposite directions.
Are published ESG software comparisons independent?
Often not, and it is easy to check.
Several comparisons that rank for these terms are published by a vendor that appears in its own table, sometimes at number one.
That does not make their research worthless; the tables are useful raw material.
It does mean supplying your own scoring criteria, because the columns of a comparison decide its winner.
Does any ESG platform handle ESOS?
ESOS is a UK-only energy audit on a four-year cycle, so it rarely appears in global comparisons.
What a platform can usefully do is hold total energy consumption in kWh by organisational purpose, show the 95% coverage, keep audit records and export an evidence pack a lead assessor can follow.
Phase 4 qualification is tested on 31 December 2026 and notification is due by 5 December 2027.
What is ESG compliance software?
ESG reporting software pointed at a legal duty rather than a voluntary report.
For a UK company that means producing the SECR lines in the directors’ report, an ESOS evidence pack, UK SRS disclosures or a comply-or-explain statement if listed, and, for EU entities in scope, a CSRD sustainability statement.
The test is whether each output comes out of the software rather than out of a consultant.
What should teams evaluate when choosing ESG reporting software for CSRD and GHG compliance?
First whether CSRD reaches the group at all after Directive (EU) 2026/470 narrowed it to undertakings exceeding €450 million turnover and 1,000 employees.
Then whether one dataset can produce ESRS datapoints, including both Scope 2 methods, and the UK outputs the group also owes, with GHG Protocol measurement, current conversion factors, Scope 3 by category and an evidence trail behind every figure.
How long does ESG software implementation take?
Vendors publish their own onboarding estimates, and they are statements about their own products.
The variable they cannot control is your data: finding meter lists, fuel cards, travel and supplier spend, and naming an owner for each feed, usually takes longer than configuring the platform.
Plan the first year as collection, with the finance close as the real deadline.
Is ESG still relevant in 2026?
The reporting duties a UK company carries are in force and moving, not fading: SECR continues after DESNZ’s 2026 review, ESOS Phase 4 qualifies on 31 December 2026, and listed companies report against UK SRS or explain from periods beginning on 1 January 2027.
What has narrowed is the EU side, where Directive (EU) 2026/470 cut CSRD’s scope.
The label matters less than which of those duties you carry.
What are the most popular ESG reporting platforms?
This site does not rank or count popularity, and nobody here has tested any product.
The alphabetical register of 73 vendors, each described in its own published words and showing only the price it publishes, is on the carbon reporting software page.
Use it as a longlist source, then hold each vendor to your own written requirements.
Who are the biggest ESG data providers?
ESG data providers in the investor sense are ratings and data vendors, not reporting software, and in the UK providing an ESG rating comes within the FCA’s perimeter from 29 June 2028 under SI 2025/1349.
A company buying software to produce its own disclosures is making a different purchase from an investor buying data about it.
Does ESG software need to cover GRI and SASB?
Only if a customer, investor or your own board asks for them: neither GRI nor SASB is a UK legal requirement.
SASB’s industry standards are maintained by the ISSB and inform IFRS S2, and UK SRS S2 is built from that; GRI is a broad stakeholder framework.
Treat them as voluntary columns on a requirements list rather than as a measure of whether a platform fits your legal duties.
Does ESG software cover UK CBAM?
UK CBAM is a tax on imports of aluminium, cement, fertiliser, hydrogen and iron and steel from 1 January 2027, under Part 5 of the Finance Act 2026, so it is an importer’s liability rather than a sustainability disclosure.
Some platforms offer embodied-emissions calculations that feed a return; the duty and the rules are published by HMRC and the government’s CBAM collection.
What does the FCA’s draft TN 803.1 mean for ESG software?
It is draft guidance, open for comment until 28 October 2026, proposing that an explanation under comply or explain can be short and proportionate and need not give a timeframe or address each requirement separately.
For software, the practical point is the same as before: keep a record of what was met and what was not, from which the explanation is written.
Are ESG ratings providers regulated in the UK?
Not yet.
The ESG Ratings Order, SI 2025/1349, made on 15 December 2025, brings providing an ESG rating within the FCA’s perimeter from 29 June 2028.
Until then a rating from a ratings provider is an unregulated private opinion, and a ratings provider is a different purchase from reporting software.
Does UK law require social and governance reporting?
In narrow, separate duties rather than one framework.
Directors must have regard to the community and the environment under section 172 of the Companies Act, and the strategic report carries a section 172(1) statement.
A commercial organisation with turnover of £36 million or more publishes a modern slavery statement, and an employer with 250 or more employees publishes gender pay gap figures.
Broader social and governance indicator lists answer to customers, investors and voluntary frameworks, not to a single UK statute.
Is the UK Corporate Governance Code a sustainability reporting requirement?
No. The FRC’s 2024 Code deliberately contains no sustainability reporting requirement, because the listing rules and the Companies Act already require climate-related disclosures.
What it does contain is Provision 29, which asks the board to declare the effectiveness of material controls, including controls over narrative and ESG reporting, for financial years beginning on or after 1 January 2026.
Does ESG software cover the Companies Act climate disclosures?
Section 414CB of the Companies Act 2006 sets eight climate-related disclosures for the largest traded companies, banks, insurers, AIM companies and companies with turnover over £500 million, above a 500-employee floor.
The Department for Business and Trade confirmed in February 2026 that UK SRS S2 is a national reporting framework for section 414CB(6), so a company reporting under S2 does not need to duplicate its disclosures.
The test for software is whether it holds the climate metrics once and maps them to whichever applies.
What should ESG software security look like?
No UK reporting regime sets a security standard for ESG software, so the questions come from general standards.
ISO/IEC 27001:2022 is the best-known standard for an information security management system, and the NCSC’s Cyber Essentials is built on five technical controls.
Where the vendor processes personal data for you, Article 28(3) of the UK GDPR requires a contract covering instructions, confidentiality, security, sub-processors, data subjects’ rights, assistance, end-of-contract provisions and audits.
Which ESG reporting tool suits a small business budget?
This site names no product, and prices appear only where a vendor publishes them.
A business below the SECR and ESOS tests, not quoted and not bidding for in-scope central government contracts, has no statutory duty on size alone, and a spreadsheet with the DESNZ factors and a written method is enough to start.
A supplier to an EU company reporting under CSRD may be asked for data, and the value-chain cap limits what that reporter can require of an undertaking with 1,000 employees or fewer.
The S and the G
Social and governance reporting in UK law
UK law asks for social and governance information in narrow, separate duties, and none of them is an ESG framework.
Each of these is a separate document, on a separate clock, owned by a different part of the business.
So ESG software with a long list of social and governance indicators is answering to customers, investors and voluntary frameworks, not to one UK statute.
The ESG criteria page sets out what each pillar is measured on.
