Sustainability Figures That Stand Up to an Assessor: We Make Every Number Traceable
Reporting is the easy part. We put your energy, travel and supplier data into one system of record, so any figure can be followed back to its source and its method.

In Brief
- A report assembled from spreadsheets takes months, and last year's calculations are hard to retrace. When an assessor or a customer asks where a number came from, the team has to reconstruct the answer.
- We see four actions: a register of every indicator, a named owner and source for each, honest labels on supplier data, and one figure traced end to end before anyone else asks.
- Thinqmesh sets up your system of record on your own energy, travel and supplier data in four weeks, and plans the first traceable footprint at eight.
Your sustainability report probably begins as a round of requests to plants, finance and purchasing, and the figures come back in different units, from different periods, in different files. Compiling them takes months. The harder moment comes afterwards, when an assessor, a customer or an investor asks the same question of any single number: where did this come from?
A Figure Is Only as Strong as the Trail Behind It
In India, SEBI requires assessment or assurance of BRSR Core for listed entities on a glide path that reaches the top 1000 by market capitalisation in FY 2026-27. Each indicator is built from records that live in different systems, and an assessor expects to follow the figure back to them.
A final spreadsheet adds the inputs up, but it seldom keeps how they were converted, which emission factor applied or who approved them. Supplier data adds a further gap, because it will stay partial for some time. We treat reporting as a data problem first, with sources, owners and methods written down, and the communication follows from numbers you can defend.
Four Actions That Make a Sustainability Figure Defensible
Each one works before any platform is chosen, and each makes next year's report easier to produce than this year's.
Keep a Register of Every Reported Indicator
One list states, for each indicator, where it comes from, how it is converted and which version was used.
Fuel sits in purchasing records, electricity in utility bills, water in meter logs, waste in vendor certificates and wages in payroll. A register records the source system, unit, conversion, emission factor and version for each, along with the evidence you keep. It is the first thing an assessor asks to see.
Get started
- List the ten indicators you report most often.
- Beside each, write where the raw figure lives and who produces it.
Name an Owner and a Source System for Each Number
A figure with an owner can be questioned and corrected. A figure without one drifts between teams.
Ownership turns reporting into a routine, similar to a financial close. Each owner confirms their figure on a set date, and corrections are made at the source and flow through to the report, so the same number is never reconciled twice.
Get started
- Ask each source team who approves its figure today.
- Agree a monthly date by which each owner confirms it.
Label Supplier Data by How You Obtained It
Supplier data arrives late and incomplete. Marking each figure as measured, reported or estimated keeps it honest.
An estimate is acceptable when it is labelled and its assumption is written down. Report coverage openly, showing how much of your purchasing the supplier data represents, and let the picture improve each year as collection matures.
Get started
- Request energy and emissions data from your five largest suppliers.
- Record the assumption you use wherever a supplier figure is missing.
Trace One Figure From the Report Back to Its Record
Choose a single published number and follow it to the bill, meter reading or invoice behind it.
This test shows what an assessor would find. The gaps it reveals, whether a missing conversion factor or an unrecorded approval, are the ones to close first, and they are usually smaller than the effort of explaining them later.
Get started
- Pick last year's total electricity figure.
- Follow it to the individual bills and note each step where the trail breaks.
How Thinqmesh Solves This
We begin with a review of what you must report and to whom, so that the data we collect reflects your actual obligations. Each week then adds a layer to a system your team can use.
- Week 1
Your Energy and Travel Data
We gather your energy and travel data and establish where each figure comes from.
- Week 2
Supplier Data and Methods
Supplier data is requested and assessed, and each calculation method is written down.
- Week 3
Connection to Your Systems
The system of record is connected to the sources you already use, so figures can be followed back to them.
- Week 4
A System of Record in Use
Your team is working from one system of record, with gaps in the data visible ahead of the first footprint.
You finish with one system of record in use and every gap in view. The first traceable footprint is planned at eight weeks, because supplier data is often late.
