By role

Suppliers and SMEs

Customers who report on their value chain send questionnaires, often several in a quarter, with overlapping topics and different definitions. From financial year 2027, what they may require for their sustainability reporting from suppliers with up to 1,000 employees is limited to the value-chain cap.

What Sustin provides: Each question sorted within the cap, beyond it or for another purpose; answers prepared once and reused where definitions, periods and boundaries align; an evidence trail for every answer.
Status: The worked example shows the full path; request analysis for your own files opens with Sustin profile.

ESG and reporting teams

Teams that report under the revised ESRS or the Voluntary Standard, often alongside GRI or IFRS, need to know which datapoints apply in which year and what evidence supports them.

What Sustin provides: Applicable datapoints by edition and financial year, evidence coverage, reviewed relationships between frameworks, and an assurance-ready trail.
Status: Framework data and edition tracking are available in the Framework Explorer; the workspace is in development.

Consultancies and advisors

Consultancies and researchers compare standards for many clients and need relationships they can check and reuse.

What Sustin provides: A shared registry, a review workflow with named reviewers, numbered releases and exports in SSSOM, an open exchange format; a partner programme for consultancies.
Status: Releases and the method are published; the partner programme terms are being prepared.

How framework mapping works

Public bodies and regions

Cities and regions want to show local progress and connect the organisations and communities working on it.

What Sustin provides: A living regional site that brings together local initiatives, collaborations and evidence, with framework alignment and an optional self-assessed Industry 5.0 readiness view (i5Benchmark method, pilot).
Status: In development. Region sites are created only by verified public bodies.

Communities and initiatives

Programmes, pilots, communities and campaigns want to make their goals and progress visible and keep a record of what they have done.

What Sustin provides: A living site for an initiative, under its owning organisation, or for a community or campaign, with milestones, outcomes, activity records and an evidence trail.
Status: In development. Community sites started by individuals are labelled "Community-run".

By need

Answer customer questionnaires

A customer's questionnaire mixes requests for its sustainability reporting with requests for other purposes, such as due diligence.

What Sustin provides: The applicable requirements for each question, the value-chain cap check by size and purpose, evidence linked to each answer, gaps with their reasons and a traceable response pack.
Status: Shown in the worked example; analysis of your own questionnaires is in development.

Prepare for the Voluntary Standard

The Voluntary Standard (Delegated Regulation (EU) 2026/1560) sets a Basic and a Comprehensive Module, and its Annex II defines the value-chain cap.

What Sustin provides: Every datapoint of the standard with its locator, whether it is in Annex II for your size, and reviewed relationships to GRI disclosures through shared concepts.
Status: Available in the registry and on the framework page.

Open the framework page

Move to the revised ESRS

The revised ESRS (Delegated Regulation (EU) 2026/1563) apply to financial years from 1 January 2027, with optional use for 2026; the ESRS as amended by Delegated Regulation (EU) 2025/1416 apply to 2025 and 2026.

What Sustin provides: Each edition with its application window and computed status by financial year; old and new datapoints side by side as their relationships are reviewed.
Status: Editions and windows are available; datapoint relationships between the editions are planned.

Open the framework page

Align GRI, IFRS and ESRS

Teams that use several frameworks want to prepare information once and see where definitions differ.

What Sustin provides: Concept-level relationships with plain labels, each with its basis and review status, and version tracking for every framework.
Status: Reviewed relationships between the Voluntary Standard and GRI are in this release; IFRS and ESRS relationships are planned.
