Request ESG records for acquisitions and disposals before access changes

When an operation is acquired or disposed of, record the transaction and control dates, identify which reporting requirements may be affected, and secure authorised access to the records needed for those decisions. Collect the relevant time segments separately. Do not automatically include only post-acquisition months or simply delete a sold site from every comparative period.

This guide is for reporting, finance and integration teams updating ESG data requests after organisational change. It helps preserve the evidence needed for a reporting decision. It does not determine transaction accounting, contractual rights or the final treatment under a particular reporting framework.

Open one change record for each event

Request a confirmed description of the event from the responsible finance or transaction owner. Distinguish an acquisition, disposal, change in control, internal reorganisation, new facility or operational closure. They may affect reporting differently.

Capture the entities and operations affected, relevant effective dates, ownership/control facts, source documents, reporting periods potentially affected and the person responsible for the treatment decision. Avoid relying solely on the date a press release was issued or a site was added to an internal system.

Keep reporting frameworks separate

BRSR requires clarity and consistency about the standalone or consolidated reporting boundary. Source: SEBI master circular, Annexure 16, section A, question 13; Annexure 17, general guidance 2.

GHG accounting can require a different review of structural changes and comparability. The Corporate Standard discusses full-year current and base-year recalculation for significant mid-year structural changes. It also distinguishes operations that did not exist in the base year and organic growth or decline. Source: GHG Protocol Corporate Standard, chapter 5, printed pages 37–39. Do not substitute a universal “count from the purchase date” rule.

Ask the reporting owner to record a separate treatment for each relevant output, including the current report, comparative figures, base-year inventory and customer-specific schedules. If a decision is unresolved, state which data could be needed rather than narrowing the request prematurely.

Request the evidence in usable time segments

• Entity, site, equipment and meter lists before and after the event

• Monthly or otherwise relevant activity records spanning the event date

• Opening/closing meter readings or stock records where relevant

• Historical records needed for comparative or base-year decisions

• Methods, factors, definitions and previous reporting assumptions

• Changes in source systems, account numbers, units or responsible staff

• Known gaps, estimated periods and overlapping records

• Authorised custodians, retention/access arrangements and practical retrieval steps

Coordinate permissions with the transaction and information owners. Acquisition of an operation does not make every personal or third-party record freely shareable. Request the necessary reporting evidence through the authorised arrangements; do not copy whole personnel or commercial archives into an ESG folder.

A hypothetical acquisition data request

Fictional example, not a Nitium client case. A company acquires an operating site on 1 October 2025 and is preparing reports for 1 April 2025 to 31 March 2026. Finance confirms the relevant facts and asks the inventory lead to assess the reporting treatment.

The coordinator obtains three separately identified electricity schedules:

• April–September 2025: 60,000 kWh

• October 2025–March 2026: 40,000 kWh

• Prior financial year: 95,000 kWh, with its own evidence and coverage note

The two current-period segments sum to 100,000 kWh. That is a source-data reconciliation, not an instruction to include that amount in every report. Keeping the segments and history available lets the reporting owner implement the applicable treatment without reconstructing records after access has changed.

If only the post-acquisition schedule had been requested, a later full-year or historical recalculation decision could be blocked. If the site did not exist in the base year, that fact would also need evidence rather than an invented historical quantity.

For a disposal, preserve the decision trail

Record when operational responsibility and access changed, who retains the relevant source records and how authorised follow-up questions will be answered. Keep the records supporting periods already reported and the rationale for any comparative adjustment. Do not treat lower reported totals after a disposal as evidence of an operational emissions reduction.

Where access cannot be obtained, make the limitation explicit and assign the resulting reporting question. Do not manufacture a complete history by copying the last available month across the missing period.

Before closing the data request

• The event, effective dates and control facts are confirmed

• Each reporting output has a named treatment owner

• Pre-event, post-event and historical data needs have been considered

• Coverage, units and methods remain identifiable across source systems

• Access and confidentiality arrangements are authorised

• Missing records and unresolved decisions remain visible

• The approved treatment reaches every affected calculation and disclosure

Our carbon inventory checklist covers the wider preparation process. Nitium's carbon inventory and BRSR reporting support can help organise the agreed data request and its gaps. Discuss a reporting-boundary change or email contact@nitium.in with a non-confidential outline.
