GHG ACCOUNTING
From activity data to calculated emissions, every step must remain connected to its source and the method used.
- ACTIVITY DATA
- FACTOR / METHOD
- DOCUMENTED OUTCOME

Outcomes tailored to your context, frameworks and uses.




Capture your data once. Nautilus uses it for your ESG reports, ADEME submission, universal registration document and Taxonomy analyses. Every figure remains traceable.
Scope, consolidate, verify and analyse: five steps that take your data from collection to action within one shared, documented framework.

SCOPE YOUR APPROACH
Nautilus connects every outcome to the assessed activity, qualified facts, applied criterion, regulatory reference and evidence status. Human reviewers can understand the basis for the conclusion, distinguish missing evidence from a failed criterion and trace information back to its origin.

This case illustrates the calculation trail and the regulatory reference used. It is not a certification, an independent audit or a credit decision.
Carbon, ESG reporting and green finance: Nautilus organises data, records how it is processed and makes each resulting outcome traceable.
From activity data to calculated emissions, every step must remain connected to its source and the method used.

Indicators become usable when they remain connected to the references and evidence that explain them.

The analysis relies on explicit criteria, a traceable classification and retained evidence supporting the conclusion.

Nautilus adapts to the activities, obligations and data being processed, supporting public and private organisations with different sector-specific challenges.
PUBLIC SECTOR & LOCAL AUTHORITIES Structure varied information, document processing and produce usable outcomes for administration, reporting and public-sector management.
Explore the sectorSustainability requirements do not rely on a single framework. Nautilus maps data, analyses and evidence to the applicable frameworks while keeping their origin and processing clear.
Nautilus Solutions brings together reporting, sustainability and technology expertise. We work closely with the real requirements of public and private organisations so that the resulting data remains clear, documented and useful over time.
Nautilus Solutions grew from a simple conviction: regulatory compliance should never be a barrier, but a starting point. From Paris, our team supports companies and public institutions seeking the same outcome — turning obligations into sustainable opportunities without compromising rigour.
Describe your data and reporting context: together, we will assess what can be structured, connected and documented.
