Verifiable ESG evidence

Better decisions for the people whose money it is.

Every holding, with the record behind it — where it sits, which way it is moving, and what is driving it. So fund managers and trustees can act on what they own: question a name, shift a weighting, and show the evidence behind either.

Our approach

Independent and transparent

Sustain ESG Lab assesses more than 5,000 listed companies across twenty independent data sources — independently derived emissions, validated science-based targets, physical climate risk and monitored controversies. The methodology is published in full and every signal links back to its origin, so any rating can be examined and tested on the same evidence.

20,000+companies screened, listed issuers and the subsidiaries they own
20+independent data sources reconciled
1,000sof holdings screened in a single scheme
12mtrend on every company, not a point-in-time snapshot

Independent

Ratings are constructed from public and third-party evidence. Companies do not fund, review or influence their own assessment.

Transparent

The methodology is published rather than proprietary. Every score traces to the signals behind it, and every controversy to its source article.

Verified

Entity resolution and point-in-time attribution match every signal to the right company before it counts, and each is corroborated across independent sources.

How the data is built

AI agents turn public records into evidence

Our agents work continuously, doing the collection and preparation that would otherwise take an analyst team. Every figure they produce can be traced back to the record it came from.

  1. Fetch

    Agents collect new records from every register, enforcement docket and target registry we monitor.

  2. Normalise

    Names, dates and codes arrive in each source’s own format. They are converted to one common format.

  3. Structure

    Each record is matched to a company by its identifier, not its name, and linked to the parent that owns it.

  4. Validate

    Records are checked against the published rules and corroborated across independent sources before they count.

  5. Report

    Only validated records reach the screens and reports, each one linked back to the source it came from.

Evidence

Evidence behind every finding

You should be able to check a finding before you rely on it. These pages set out the rules that decide what counts, the registers each record comes from, and what a finished report looks like.

1,284

new regulatory determinations added to the evidence base in August 2026, each linked to the register that published it.

What you can do with it

Solutions

Six ways to work from one body of evidence. Trustees test a default fund against its own exclusions, advisers and wealth managers screen a client’s holdings, and asset managers and consultants track where enforcement falls and who is improving.

Portfolio screening

Paste a holdings list and get every name back with its evidence — what a regulator determined, when, and where to read it. Filter by what matters to your client.

Wealth managers · Financial advisers

Pension fund evidence report

Test a scheme's own published exclusions against what the default fund actually holds, with every breach named and sourced. It also states what could not be tested, and why.

Pension funds · Master trusts · Consultants

Exclusions and critical findings

Every company carrying a determination serious enough to matter, with its regulator, date and source. Grouped by case, so one cartel judgment against ten defendants reads as one judgment.

Asset managers · Pension funds

Momentum and trend analysis

Every new determination made against a company in the last twelve months, and every newly validated target in its favour. Absence of bad news is never counted as improvement.

Asset managers · Consultants

Sector and country heatmap

Where enforcement actually falls — by sector, globally or in one country. Coverage is a column of its own, so thin data never looks confident.

Asset managers · Consultants · Pension funds

Leaders

Companies carrying no determination at all, with a validated emissions target and emissions falling. Each condition dated and checkable.

Who it is for

Intelligence on what a portfolio needs to hold

From trustee boards to compliance desks, from financial advisers to asset managers — anyone who has to stand behind a holding when a committee, a consultant or a regulator asks why it is there.

Head of Responsible Investment

Interrogate every rating down to the signals behind it. Published construction and source-linked evidence mean a score can be explained to a client, tested internally and defended on its merits.

Asset managers · Consultants

Trustee Director

Take decisions on the default fund with evidence the board can verify for itself. What the scheme holds, how it has moved and what changed since the last meeting, in a form that goes straight into a board pack.

Master trusts

Pensions Manager

Bring holdings from every manager into one consistent view. Thousands of lines screened together and returned as a single picture the committee can act on.

Master trusts · Pension funds

Head of Compliance and Risk

Substantiate every sustainability claim the firm makes. Traceable sources, dated records and reproducible ratings provide the evidential basis the anti-greenwashing rule expects.

All regulated firms

Investment Consultant

Compare managers and mandates on a consistent, independent basis. The same methodology applied across every book makes advice to clients directly comparable and straightforward to evidence.

Consultants · Fiduciary managers

Financial Adviser

Match a client's stated preferences to what a fund genuinely holds. Holdings-level ratings show what is actually there and record why the recommendation was suitable.
