ESG Ratings

Our fictional case follows Alderwick Investment Office, whose analyst receives two differently framed ESG assessments for a company under review.

The investment committee asks whether the apparent disagreement is an error, a timing difference or a consequence of the methods answering different questions.

The analyst starts with the original provider descriptions rather than averaging the outputs or copying the most favourable description into a board paper.

The standards homepage distinguishes ratings from reporting standards, while the ESG standards guide explains how a reporting basis and claim should be identified.

No real company rating or invented numerical score is assigned in this fictional teaching case.

Alderwick’s review starts by identifying missing metadata, not by deciding which provider is right.

The analyst can then explain whether a meaningful comparison is possible at all.

MSCI’s public description places companies relative to industry peers on its letter scale rather than presenting an absolute cross-industry impact score industry-relative assessment.

Sustainalytics describes its ESG Risk Ratings through unmanaged risk, so reading a higher number as automatically better reverses the intended interpretation unmanaged risk and score direction.

Alderwick therefore keeps the two outputs in separately labelled columns and writes a plain-language explanation of the different questions.

The analyst does not create an exchange table converting one provider’s letter into the other provider’s number.

This source-based distinction is more useful than claiming that every rating disagreement demonstrates poor data quality.

The fictional comparison describes the methods without assigning either rating to a named issuer.

The committee receives the reason for the difference rather than an invented composite score.

Alderwick finds that one document refers to a company-level assessment while another file concerns a property investment assessment, making a direct comparison inappropriate.

GRESB’s methodology disclosures describe its assessment basis and should be read in their own context rather than converted into an MSCI or Sustainalytics equivalent methodology disclosure.

The analyst records whether the evidence concerns a company, fund, asset portfolio or particular assessment response before writing a conclusion.

The GRESB assessment guide owns the scheme-specific workflow, while EcoVadis assessment owns its respondent task.

This general guide concerns interpretation and selection, not a competing summary of every provider questionnaire.

Alderwick’s analyst flags the property-assessment file as relevant background but excludes it from the company-method comparison.

The review explains the exclusion rather than silently dropping an inconvenient result.

The UK ESG Ratings Order is made law with substantive commencement on 29 June 2028, rather than a statement that the future regime already applies in full Article 2.

The FCA status page and consultation explain the proposed approach, with the source status requiring a current check before a buyer repeats a regulatory claim consultation status proposed rules.

The explanatory memorandum helps readers understand the investment-use perimeter, while the operative wording remains in the Order explanatory memorandum regulated activity.

Alderwick’s procurement paper therefore separates a provider’s current evidence from an expectation about future authorisation.

The buyer does not assume that a rating used in procurement is automatically inside or outside the perimeter solely because of that label.

The fictional committee receives the exact source type beside the conclusion.

That makes an outdated consultation summary easier to identify before it is reused in procurement.

The EU ESG Ratings Regulation defines its scope and rating-provider framework separately from the UK’s later substantive commencement EU regulation UK commencement.

EcoVadis’s own regulatory page describes its notification and application intentions, which are statements about its own position rather than an independent authorisation finding owner regulatory statement.

The ESMA document used here is expressly a list of firms that notified under Article 51, so the analyst does not relabel it an approved-provider list document title and status.

Alderwick asks a prospective data supplier to provide the actual source supporting any current authorisation claim and records the date of the check.

This example does not infer a regulatory conclusion for another provider from its absence in a particular notification document.

The fictional reviewer retains the original document title so that the evidence cannot acquire a stronger meaning in a later slide deck.

Notification, application and authorisation are written as separate words throughout the purchasing record.

Alderwick’s original pilot imports two clearly labelled assessment records, then changes one source date and one entity identifier to test whether the platform flags a mismatch.

The buyer asks what data it may retain, share and export under the actual contract rather than assuming that a subscription grants unrestricted reuse.

The implementation supplier must preserve the provider name, method basis, scale direction and assessment date in the export.

The analyst remains responsible for interpreting the output for the committee’s decision, while the technical team owns accurate transmission and identification.

The software RFP helps turn those requirements into acceptance questions without inventing a provider’s licence terms.

The pilot does not compare vendor accuracy or calculate an investment recommendation.

It tests whether the system preserves the information needed for a competent user to interpret the assessment.

Alderwick’s final fictional paper explains why the two company methods can differ, why the property assessment is a separate object and which source questions remain unresolved.

The committee receives a supported interpretation rather than a combined rank or a claim that a favourable rating proves every environmental and social outcome.

The ESG governance guide helps assign review responsibility, while the scheme-specific guides retain their own assessment and evidence workflows.

If an adviser is engaged, the brief should specify methodology interpretation, data reconciliation or regulatory review separately from buying the data feed.

The useful outcome is a decision-maker who understands the evidence and its limits, not a spreadsheet that treats every rating label as the same measurement.
