Purchased Steam and Cooling: Bring Supplier Data Into Your Scope 2 Review

Look beyond the electricity account

An industrial site may buy steam from a neighbouring facility or cooling from a shared utility operator. Those purchases can sit in service contracts and operating-cost accounts rather than the electricity ledger. When a reporting team starts with electricity bills alone, it may miss an important part of the energy picture.

For Indian manufacturers, campuses and commercial facilities, the practical first step is to identify every purchased energy service and connect it to a responsible supplier contact. That exercise supports both emissions reporting and a more informed procurement discussion. A quote becomes easier to assess when the buyer understands what is measured, what is delivered and what evidence supports the supplier’s emissions information.

Confirm the accounting boundary before collecting numbers

The GHG Protocol Scope 2 Guidance covers purchased or acquired electricity, steam, heat and cooling. Classification still needs to reflect the reporting organisation’s boundary and the actual arrangement. A contract called an “energy service” does not settle who owns or controls the relevant equipment for inventory purposes.

Ask the reporting lead to review the contract and operating arrangement with facilities. Identify the energy received, the delivery point and the entity responsible for generation. If the company operates its own boiler, do not casually treat its fuel combustion as purchased steam simply because an outside contractor maintains it.

Document the conclusion and any unresolved boundary questions. Procurement, facilities and sustainability should use the same description of the arrangement before requesting a supplier calculation.

Turn the invoice into a usable activity record

A monthly charge is not automatically a measure of energy consumption. Ask the supplier to explain the billed quantity, its unit and how it was determined. Where the invoice uses a service fee or an allocated share, identify the underlying measurement or allocation record.

For steam, have a competent technical person confirm how the available measurements translate into the energy basis needed for the calculation. Do not substitute an assumed conversion merely because it produces a convenient spreadsheet result. For cooling, similarly confirm whether the reported quantity describes cooling delivered or electricity consumed by the equipment producing it.

Create a simple record linking the reporting period, delivery point, measured quantity, unit and evidence reference. Record estimated quantities separately from measured ones. If supplier and site records disagree, retain the discrepancy and assign an owner rather than silently choosing the lower figure.

Ask what the emissions factor represents

Appendix A of the Scope 2 Guidance addresses steam, heat and cooling. It explains that location-based factors should reflect the fuels used and generation efficiency, and discusses contractual instruments for these energy products. This requires an appropriate thermal-energy calculation, not an automatic reuse of the site’s grid-electricity factor.

Request the supplier’s factor with its unit, reporting period, calculation basis and supporting reference. Ask whether it applies to the energy delivered to your site and whether the generation arrangement changed during the period. Where a system produces more than one energy output, obtain an explanation of the allocation approach for technical review.

The reporting specialist should assess the appropriate methods and any contractual claims against the applicable guidance. A supplier’s “green” description is a starting point for questions, not sufficient evidence for a zero-emissions entry. Keep an estimate provisional if its basis has not been resolved.

Treat recovered energy as a question to investigate

A seller may describe steam as recovered or waste heat. That can be commercially relevant, but the description alone does not establish the buyer’s emissions factor. GHG Protocol’s technical explanation of by-product steam says that direct-line waste steam, heat or cooling should still be reported based on the underlying emissions from its original generation process.

Ask the supplier to explain the source and provide the information needed for the assessment. Separate that inventory question from any proposed avoided-emissions claim. A statement about an alternative use of heat does not, by itself, answer how the purchasing company should prepare its inventory.

Compare offers on a consistent service basis

Consider a hypothetical factory comparing two steam suppliers. One quotation includes metering and regular emissions information; the other provides a price per billed quantity with limited supporting detail. The second offer is not automatically unsuitable, but the buyer should identify the work required to make the offers comparable.

Use an evaluation sheet with separate technical, commercial and reporting sections:

Review area	Question for the buyer and supplier
Service specification	Are delivery conditions and reliability requirements comparable?
Measurement	What is metered, estimated or allocated?
Commercial scope	Which charges and support services are included?
Emissions evidence	What factor and method will be supplied, and for which period?
Change notification	Who reports a change in source, equipment or calculation basis?

Agree the importance of each section before selecting a supplier. A lower quoted rate should not conceal extra metering, review or administration work. Equally, better documentation does not remove the need to assess technical suitability and service reliability.

Make the data request part of routine operations

Propose a recurring information schedule alongside the service arrangement. Identify what the supplier can provide, when it will arrive and who handles corrections. Have the authorised commercial team incorporate agreed obligations into the relevant documents; an internal checklist does not create supplier duties on its own.

Test the process using one reporting month. Ask facilities to confirm the quantity, the reporting team to review the factor and finance to reconcile the invoice scope. Save the resolved example so future months follow a consistent approach, and reopen the assessment when material circumstances change.

ClimateCred’s GHG reporting and CAF service areas provide a starting point for organising purchased-energy records. Bring a sample invoice, the supply arrangement and any available supplier calculation to a consultation. The immediate objective is a clear measurement basis and an evidence request the supplier can actually answer.
