ESG reporting software helps UK companies collect their environmental, social and governance data, check it, and turn it into disclosures such as SECR statements and UK SRS or CSRD reports. If you are new to the topic, our guide to what ESG reporting involves covers the basics first.
The UK government finalised the UK Sustainability Reporting Standards (UK SRS) in February 2026. Since then, the Financial Conduct Authority (FCA) has confirmed that in-scope listed companies will report against them on a comply-or-explain basis for periods starting on or after 1 January 2027. Beyond the listed market, UK SRS is currently available for voluntary use. Verdantix found that, despite regulatory and political uncertainty, investor pressure is driving the adoption of ESG software to improve data quality and streamline reporting, so the right platform depends on which rules apply to you and what your investors ask for.
In this article, we’ll cover:

What is ESG reporting software?
ESG reporting software, also called ESG software, collects a company’s environmental, social and governance data in one system, maps it to reporting frameworks such as UK SRS, CSRD and CDP, and produces the disclosures, keeping an audit trail of where each figure came from.
You will also see it called an ESG reporting platform or an ESG platform. Vendors use many overlapping labels, including ESG management software, ESG data software, sustainability reporting software and sustainability management software, and the job is the same: one governed record that every disclosure draws on, in place of spreadsheets and email chains.
Three other tools are easy to confuse with it. An ESG ratings agency such as MSCI scores other companies for investors, while this software helps a company manage and report its own data. Carbon accounting software calculates emissions across Scopes 1, 2 and 3, and ESG reporting software takes that as one input alongside social and governance data. Finally, disclosure management tools focus on producing and tagging published reports.
The 10 best ESG software companies for UK reporting
The best ESG software for a UK company depends on the rules it reports under and where its data lives. The ten ESG software providers below fall into four types: carbon-first platforms (Greenly, Sweep, Watershed, Sami), disclosure and audit-led platforms (Workiva, Novisto), compliance-led platforms built around EHS or supply chain obligations (Cority, osapiens) and enterprise data suites (IBM Envizi, SAP). Greenly, which publishes this guide, is one of the ten. For a closer look at the carbon-first group, see our comparison of carbon management platforms. This is not a ranking and we have not tested the products: each entry summarises what the vendor states on its own website.
Greenly
Greenly combines carbon accounting and ESG reporting on one data foundation, with support for more than 15 frameworks, including CSRD, ISSB, TCFD, CDP, SBTi, EcoVadis and VSME. It automates the double materiality assessment, reports on Scopes 1, 2 and 3, and includes expert support. More than 4,000 companies use it.
Best for: companies that want carbon accounting and ESG reporting handled together. See Greenly’s ESG reporting platform.
Sweep
Sweep offers a dedicated UK SRS solution, pre-mapped to UK SRS S1 and S2, and the same data also feeds CSRD, CDP, GRI and investor reports.
Best for: UK companies that want to prepare UK SRS reports from a single data set.
Watershed
Watershed gives sustainability teams one platform to measure, disclose and defend ESG data. It supports CSRD, ISSB (IFRS S1 and S2), TCFD and the UK’s SECR framework, measuring carbon as well as water, waste, land use, biodiversity and social metrics, and including AI drafting.

Sami
Sami is a carbon accounting platform sold alongside SGS’s sustainability advisory services, with more than 800 active customers and a catalogue of over 250 decarbonisation actions. Its ESG Hub, covering ESRS, VSME, EcoVadis and B Corp reporting, is available in France only for now, so UK companies would currently use Sami for carbon accounting.
Best for: companies that want carbon accounting backed by consultants.
Workiva
Workiva puts ESG reporting on the same platform as financial reporting and applies financial-grade rigour to it. Its ESG Explorer offers pre-built frameworks, with SASB, GRI and TCFD among those shown, while Workiva Carbon covers Scopes 1, 2 and 3 accounting. The platform also handles SEC and statutory reporting, management reporting and internal controls.
Best for: companies that want ESG reporting inside their financial reporting system.
Novisto
Novisto, a Montreal-based sustainability management platform, acquired London-based carbon management company Minimum on 31 March 2026, adding native carbon accounting to its ESG data and reporting. It is a SASB licensee and a GRI-licensed solution, with ready-to-use templates covering CSRD, GRI, SASB, TCFD and ISSB. Each data point is entered once and reused across frameworks.
Best for: enterprises that want ESG data and carbon accounting on one platform.
Cority
Cority’s EHS+ platform (CorityOne) brings environmental, health, safety, quality and sustainability programmes into one system. It is built mainly for large and mid-sized enterprises, and over 1,500 organisations use it across manufacturing, energy, mining, chemicals, healthcare and the public sector.

Which UK reporting rules should your ESG software cover?
ESG reporting software should cover the rules that apply to your company: UK SRS if you are listed, SECR if you are quoted or large, a Carbon Reduction Plan if you bid for large central government contracts, and CSRD if your group has substantial EU operations.
UK SRS and the FCA listing rules
- The UK government published the final UK Sustainability Reporting Standards (UK SRS S1 and S2) in February 2026, based on the ISSB standards, and any company can use them voluntarily.
- The Financial Conduct Authority (FCA) published its final rules on 30 September 2026.
- Listed companies in the in-scope categories report against UK SRS on a comply-or-explain basis for accounting periods starting on or after 1 January 2027, with first reports in 2028. Transitional relief lasts one year for Scope 3 emissions and two years for wider UK SRS S1 disclosures. In practice, look for software that maps your data to ISSB-based standards and lets you build Scope 3 data during the relief year.
For more information, read our guide on what the ISSB is.
SECR
Streamlined Energy and Carbon Reporting (SECR) has applied since 1 April 2019 to quoted companies, large unquoted companies and large LLPs, which report their energy use, greenhouse gas emissions and energy efficiency actions in their annual reports. For unquoted companies, large means exceeding two of these three limits: 250 employees, £36 million turnover and £18 million balance sheet total. The April 2025 rise in company size thresholds did not change the SECR limits. Your software needs to produce the energy and Scope 1 and 2 figures that go into the annual report.
PPN 006 carbon reduction plans
Procurement Policy Note 006 covers relevant procurements advertised on or after 24 February 2025 by central government departments, executive agencies and non-departmental public bodies. The note applies where the estimated contract value is above £5 million a year including VAT, unless it would not be relevant or proportionate. Bidding suppliers must provide a Carbon Reduction Plan that confirms a net zero commitment for UK operations by 2050, reports Scope 1 and 2 emissions plus a defined set of Scope 3 emissions, and is published on the supplier’s website. Check that your chosen platform can export a plan in this format.
CSRD for UK groups with EU operations
UK groups can fall within the EU’s Corporate Sustainability Reporting Directive (CSRD) through their EU operations. Since the Omnibus I Directive (Directive (EU) 2026/470) came into force on 18 March 2026, the CSRD now applies to EU companies with more than €450 million net turnover and more than 1,000 employees. Non-EU groups are in scope when they generate more than €450 million net turnover in the EU and have an EU subsidiary or branch above €200 million. Member States must transpose the changes by 19 March 2027. If this applies to you, double materiality assessment and ESRS reporting are the capabilities to test in a demo.
How do you choose ESG reporting software? 7 checks to run
Choose ESG reporting software by starting from your reporting obligations and current data gaps, then working out how many people will use the platform day to day. From there, seven checks are worth running before you commit:
- Obligation coverage: does it map your data to the rules you report under, such as UK SRS, SECR, CSRD or CDP, without manual reformatting for each one? If you are starting from TCFD-aligned reporting, our comparison of TCFD software is a useful companion.
- Audit trail and data quality: can it handle quantitative and qualitative data, and show where each figure came from if an auditor, regulator or investor asks?
- Scope 3 build-up: in-scope listed companies have a one-year transitional relief for Scope 3 emissions, so check how the platform collects supplier data and estimates gaps before that year ends.
- Entities and room to grow: will it handle UK and EU subsidiaries together, and still fit if you add frameworks or a heavier reporting load next year?
- Integrations and usability: does it connect to your ERP and accounting systems, and will the people entering data each month find it straightforward, as well as the person who chose it?
- Security: how is your data stored, who can access it, and what certifications does the vendor hold?
- Support and total cost: does the vendor offer methodology help as well as technical support, and can it give you a three-year cost that includes any assurance support?
Ask each shortlisted vendor for a live demo with data close to your own before signing anything, and read customer reviews to see how it performs once you are a paying customer. Reporting well can also pay off: in PwC’s 2025 Global Sustainability Reporting Survey, more than two-thirds of companies that had already reported under CSRD or ISSB said they gained significant or moderate value from the data beyond compliance, and 28% said significant. The right software is the one that fits your obligations and your team.
What about Greenly?
ESG reporting software saves time by collecting each data point once, reusing it across frameworks and keeping the evidence attached to every figure, so teams stop rebuilding the same answers in spreadsheets.
Greenly applies this in four places:
- Built-in APIs pull data from across functions and suppliers, and AI cleanses, maps and categorises the raw data.
- Answers entered once are reused across frameworks and stored in a central library, so the proof stays attached to each figure.
- AI pre-fills narrative sections from internal files.
- A mix of automated checks and expert audits then verifies the data, and a single click generates the report, including the xHTML and XBRL files used for CSRD.
UK teams reporting under UK SRS can start from Greenly’s UK SRS reporting platform, which connects GHG Protocol data to IFRS S1 and S2 disclosures. To see how it would work with your own data, book a demo.
Questions & Answers (Q&A) about ESG reporting software
What is the best ESG software for UK businesses?
It depends on the rules you report under and where your data lives. Greenly, Sweep, Watershed and Sami start from carbon data, Workiva and Novisto suit disclosure and audit-led reporting, Cority and osapiens suit EHS and supply chain teams, and IBM Envizi and SAP suit companies already built around their ecosystems.
Is ESG reporting mandatory in the UK?
Some of it is. SECR is mandatory for quoted companies, large unquoted companies and large LLPs, and listed companies in the FCA’s in-scope categories report against UK SRS on a comply-or-explain basis from periods starting on or after 1 January 2027. UK SRS is otherwise voluntary, and other rules may apply to you, so use our legislation checker to confirm your position.
What is the UK's equivalent to the EU's CSRD?
The UK Sustainability Reporting Standards (UK SRS), finalised by the UK government in February 2026 and based on the ISSB standards. They are available for voluntary use, and the FCA’s final rules apply them to in-scope listed companies on a comply-or-explain basis. UK SRS and CSRD are separate frameworks with different scopes.
Is ESG still relevant?
Yes, for reporting. The FCA’s final rules for listed companies start applying to periods from 1 January 2027, and S&P Global counted 35 jurisdictions that had adopted the ISSB standards, on a voluntary or mandatory basis, by 22 July 2026.
Are ESG software companies the same as ESG rating agencies?
No — this is a common mix-up. ESG software helps a company manage and report its own ESG data. Rating agencies like MSCI assess other companies' ESG performance for investors. If you're choosing a tool to run your own reporting, you want ESG software, not a ratings provider.
