Carbon Accounting & Technical Assurance

Every reported emissions figure eventually invites scrutiny. Not because organisations lack commitment, but because sustainability information increasingly influences decisions beyond annual reporting. It informs financing negotiations, investor due diligence, procurement requirements, insurance assessments, regulatory disclosures, and corporate strategy.

As the importance of sustainability information grows, so do the questions behind every reported number.

• Where did this figure come from?
• How was it calculated?
• Which assumptions were applied?
• Can the calculation be reproduced?
• Is the methodology consistent across the organisation?

The quality of those answers depends on far more than calculation software or emission factors. It depends on the systems that generate the information.

Coreveon helps organisations build those systems.

Carbon Accounting That Supports Business Decisions

Many organisations begin measuring greenhouse gas emissions to meet reporting requirements. Over time, those same emissions inventories become part of financing discussions, investment decisions, supplier engagement, climate target setting, and external assurance.

Information originally prepared for disclosure begins supporting decisions with financial, operational, and regulatory implications. The objective therefore changes.

Carbon accounting is no longer simply about calculating emissions. It is about producing information that remains consistent, traceable, and understandable wherever it is used.

Greenhouse Gas Inventory Development

A reliable emissions inventory begins long before the first calculation:

• Organisational boundaries must be defined
• Emission sources identified
• Methodologies selected
• Activity data collected
• Assumptions documented

Only then can calculations produce results that are meaningful over time.

We develop greenhouse gas inventories across Scope 1, Scope 2 and Scope 3 emissions in accordance with the GHG Protocol Corporate Standard.

Our work establishes:

• Organisational and operational boundaries
• Consistent calculation methodologies
• Appropriate emission factors
• Transparent assumptions
• Documented calculation processes
• Clear governance over emissions information

The result is an inventory that provides a dependable foundation for reporting, target setting, assurance, and decision-making.

Data Mapping

Most emissions are not created inside sustainability teams. They originate from everyday business activity:

• Invoices.
• Fuel purchases.
• Electricity consumption.
• Travel records.
• Procurement systems.
• Supplier information.
• Financial systems.
• Operational databases.

The challenge is rarely the absence of data, but connecting those business records to emissions calculations in a consistent and repeatable way.

We design data structures that create a clear relationship between source information and reported emissions. This reduces manual processing, improves consistency between reporting periods, and strengthens confidence in reported results.

Pre-Assurance Reviews

Independent assurance should confirm the quality of reported information. It should not be the first time weaknesses are identified.

Before external assurance begins, we review:

• Calculation methodologies
• Supporting evidence
• Data completeness
• Internal governance
• Documented assumptions
• Quality control processes

The objective is to identify gaps while they remain practical to address.

How We Can Help

Whether your organisation is establishing its first greenhouse gas inventory, strengthening existing reporting processes, preparing for external assurance, or improving the connection between operational data and sustainability reporting, Coreveon provides the technical foundation required to produce information that can be relied upon.

Better information. Better decisions.
