Many data owners
Sites, meters, fuel cards and invoices arrive in different formats and on different timetables.
Every figure.
Every source.
Traceable.
Carbon MRV for reporting teams. CarbonSight keeps the origin of every input, applies the approved method, turns gaps into exceptions and records who approved each figure, so your assurer can follow it back to source.
- Source provenance kept
- Gaps become exceptions
- Evidence for your assurer
Illustration. Data sources and evidence export formats are confirmed during scoping.
Traceable sourcesOperational and sustainability data keeps its origin.
Methods on the recordThe approved method and version are part of the record, not an assumption.
Evidence for assuranceSource, method, exceptions and approvals in an exportable record.
The reporting team’s reality
The number is due. The trail behind it is scattered.
Carbon data comes from many owners and systems, and it is reviewed by people who are paid to be sceptical.
When an assurer asks where a figure came from, which method was used and who approved an estimate, the answer should not depend on one person’s spreadsheet.
Silent gaps
Missing or inconsistent inputs get quietly filled in instead of reviewed.
Method drift
Which calculation method and version produced a figure is assumed, not recorded.
Assurance pressure
The review package takes weeks to assemble when evidence lives in separate places.
One workflow from source data to review package.
CarbonSight is generally available. It organises the MRV workflow; the assurance opinion always comes from your assurer.
CarbonSight
Organises source data, calculation, methodology, review, exceptions and evidence into a traceable MRV workflow.
Assurance opinion
CarbonSight prepares the evidence. It does not certify your figures.
TrustOps + Evidence Fabric
The approval boundary before a figure is final and the record behind it afterwards.
Start with the data you trust least.
Each area needs different source context. Your reporting and assurance teams decide what is in scope.
Energy and fuel
Bring meter readings, utility invoices and fuel records in with their origin kept, so every activity figure traces back to where it came from.
- Meter readings
- Utility invoices
- Fuel records
- Provenance
Supply chain (Scope 3)
Supplier and spend data come from owners outside your organisation, which makes provenance and review harder to show. Which Scope 3 categories are in scope is your reporting team’s decision.
- Supplier data
- Spend data
- Data owner
- Exception review
Methods and versions
Apply the approved calculation method to the source data. The method and its version are part of the record, so a later reviewer can see exactly how a figure was produced.
- Approved method
- Version
- Factors used
- Change history
Assurance package
Export source context, method, exceptions, approvals and final results for your assurer and reporting. The assurance opinion is given by your assurer, not by CarbonSight.
- Evidence export
- Exceptions log
- Approvals
- Final figures
From source data to an assured figure.
Six steps. Where data is missing, that is an exception for a person to review, not an estimate made quietly.
- 01 · TRACE
Bring in source data
Operational and sustainability data arrives with its origin kept.
- 02 · CALCULATE
Apply the approved method
The method and version are recorded with the result.
- 03 · CHECK
Surface exceptions
Missing or inconsistent data becomes an exception to review.
TrustOps: no silent gap-filling.
- 04 · APPROVE
Review and approve
The reporting team approves the figure within the policy boundary.
TrustOps: named approver recorded.
- 05 · RECORD
Keep the evidence
Source, method, review, exceptions and approvals go to Evidence Fabric.
- 06 · EXPORT
Prepare for assurance
Evidence is exported for your assurer and reporting.
Your assurer gives the opinion.
One site. One data gap. An estimate you can defend.
A synthetic reporting case. CarbonSight surfaces the gap instead of filling it; the policy decides who may approve an estimate.

TrustOps · Policy and approvalPolicy example
- OBSERVECarbonSight checks completeness
Source file, period coverage and the missing days stay attached to the figure.
- ESCALATECARB-02: estimate needs approval
Any proposed estimate goes to the named reporting approver with its basis.
- DENYCARB-04: no silent gap-filling
A figure cannot be finalised with an unreviewed gap or an unrecorded method change.
- RECORDAssurance-ready record
Source, method version, exception, approver, decision and final figure.
The people who prepare, approve and assure.
Sustainability and reporting teams
Own the source data, the approved methods and the review of exceptions before reporting.
Data owners across sites
Provide meter, fuel, invoice and supplier inputs with clear ownership and provenance.
Assurers and auditors
Follow a figure back to its source, method and approval in an exported evidence record.

Software organises the evidence. People approve the figure.
Every figure that leaves the team passes through the boundary you agree. These are example policies for a reporting engagement, not a deployed rulebook.
Use agreed sources
Only the data sources and owners agreed for the reporting scope feed the calculation.
Approve estimates
A proposed estimate for missing data goes to the named approver with its basis attached.
No silent changes
Unreviewed gaps and unrecorded method changes cannot reach a final figure.
- Source context
- Method and version
- Exceptions
- Review and approval
- Final result
- Export
Evidence fields and export formats are agreed with your reporting and assurance teams. How TrustOps works · Evidence Fabric
One reporting workflow. A trail your assurer can follow.
Start with one reporting area and its source data. Sources, methods, export format and success criteria are confirmed during scoping; pricing is discussed privately.
Agree the scope
Choose the reporting area, data owners, approved methods and reviewers.
Map the sources
Connect sample source data with provenance and agree the exception rules.
Review together
Work through exceptions and approvals, and test the evidence export.
Check with your assurer
Confirm the export is useful for review and decide the next step.
Clear sources. Clear approvals.
Which data should we start with?
The reporting area where source data is hardest to trace back today. The scope is agreed with your reporting and assurance teams during scoping.
Who approves an estimate for missing data?
A named reporting approver agreed for the scope. The estimate, its basis and the approver are recorded with the figure.
What will our assurer receive?
An evidence export with source context, method and version, exceptions, approvals and final results, in a format agreed with your reporting and assurance teams.
What happens if we change a calculation method?
The method and its version are part of the record, so a later reviewer can see which version produced each figure. Changes follow the approval boundary you agree.
Is CarbonSight available today?
Yes. CarbonSight is generally available. Data sources and evidence export formats are confirmed during scoping.
