EU Voluntary Standard Comprehensive Module: Complete Guide to C1-C9 Disclosures

Comprehensive Module architecture: C1-C9 deepen information commonly needed by banks, investors and corporate clients.

The Comprehensive Module is not a second, independent standard. It sits on top of the Basic Module and responds to information needs that often arise in lending, investment, supply-chain assessment and commercial due diligence. Its disclosures help a counterparty understand the undertaking’s business model, sustainability-related initiatives, climate transition and risk profile, workforce and human-rights arrangements, exposure to specified activities and governance diversity.

This additional depth creates a reporting-claim decision. If the undertaking needs the complete C1-C9 dataset and can support it, Option B may be appropriate. If only two or three disclosures are relevant to a lender or customer, paragraph 25 permits those selected disclosures after the Basic Module is complete. The content may be useful, but it should not be packaged as full Comprehensive Module compliance.

C1 helps the user understand what the undertaking sells, where it operates and which business relationships shape its exposure. A generic corporate profile is not enough if it does not identify the activities and relationships that make the sustainability information meaningful. C2 then deepens B2 by describing actual practices, policies, initiatives and targets, including whether suppliers or clients are covered. The optional accountability datapoint can be useful where a lender or customer needs to understand governance ownership.

Good drafting separates four concepts: a policy sets an approved direction; a practice is an existing way of working; an initiative or action is a defined intervention; and a target states an intended outcome or performance level. Combining them in one unstructured paragraph makes it difficult to understand what has been approved, implemented or measured.

Paragraphs 49-52 explain when Scope 3 can be appropriate. Manufacturing, agrifood, real-estate construction and packaging are highlighted as activities likely to have significant categories, but the decision remains based on the undertaking’s own assessment. If Scope 3 is reported, significant categories are included in accordance with the GHG Protocol approach, and the information is presented together with B3 Scope 1 and Scope 2. The article should not rename this consideration “C2.5” or imply that every Option B report automatically requires all 15 categories.

C3 is triggered when GHG reduction targets have been established. It asks for the target architecture and main actions. C4 is triggered when climate-related hazards or transition events create climate-related risks. It asks how exposure and sensitivity were assessed, the time horizons and whether adaptation actions were taken. A target does not replace a risk assessment, and a risk heat map does not replace a target disclosure.

For high-climate-impact sectors, C3 distinguishes between providing information about an adopted mitigation transition plan and stating whether and when such a plan will be adopted if none is in place. Reporting teams should not convert the “may provide” wording for an existing plan into a universal mandatory transition-plan disclosure.

Employee turnover needs a documented numerator and denominator. Management-level gender information needs a stable management definition. Human-rights policy questions are yes/no, but the evidence behind “yes” should identify the approved document, scope and issues covered. Incident disclosures require a clear definition of “confirmed”, a reporting period, case ownership, confidentiality controls and legal review. An undertaking should not disclose personal or allegation-level details that create privacy or security risks.

C8 is not a broad “controversial sectors” narrative. It is an activity-triggered revenue disclosure tied to specified sectors and, for fossil fuels, the required coal/oil/gas disaggregation. The finance team should reconcile the disclosed amount to the revenue ledger and document the activity classification. C9 applies if a governance body is in place; the undertaking should define the body and calculation used rather than assuming that a senior management group and a statutory board are the same.

Full Option B and selected C information: similar datapoints can support different reporting bases.

The undertaking has completed and reviewed B1-B11.

Banks, investors or major customers need a broad C1-C9 dataset rather than isolated datapoints.

The undertaking can identify and support every applicable C disclosure.

The employee reliefs, if-applicable triggers and voluntary fields have been mapped correctly.

Climate, workforce, human-rights, revenue and governance data have owners and methods.

Any paragraph 22 omissions are narrow, documented, identified in B1 and scheduled for reassessment.

The final index and B1 statement can support an explicit Option B claim.

Only a limited set of C disclosures is decision-useful for the intended counterparty.

The undertaking is still developing data for other C disclosures.

The user asks specifically for climate targets, climate risks or a human-rights process rather than the full module.

A full Option B claim would create an impression of completeness that the evidence cannot support.

The report can clearly label the selected information as supplementary and show it separately in the index.

This approach is more transparent than applying Option B with incomplete social and governance evidence. The response pack can provide the lender with the selected C3/C4 data and supporting methodologies, while the restricted evidence room retains the target approval, emissions workbook, flood maps and finance review.
