What changed in version 2.1
The Aircraft Operator reporting template for ReFuelEU Aviation was updated on 9 December 2025. The key change is practical. Column H in the Fuel Reporting sheet now accepts negative values, supporting corrections when fuel safety tanking data needs adjustment after reconciliation.
What changed in version 2.0
In November 2025, the template added new fields in the SAF Purchase Reporting sheet. Purchases of eligible fuels can now be allocated across different market based measures, including EU ETS, Swiss ETS, UK ETS, CORSIA, and other schemes. This improves transparency and reduces the risk of double claiming.
The non obvious upside
Better data quality without extra paperwork
Allowing negative entries is not a loophole. It recognises that operational data arrives in waves. By enabling reversals in a controlled column, the template helps teams correct earlier submissions without parallel spreadsheets.
Stronger proof of unique claims
The expanded purchase section nudges the industry toward a single source of truth. When each tonne of eligible fuel is linked to a specific scheme claim or left unclaimed, auditors and regulators can follow the trail quickly, shortening review cycles.
How to prepare
Build a monthly close process
Treat airport uplift, non tanked quantities, and fuel safety tanking as a monthly close. Lock assumptions, record adjustments, and keep evidence for each change.
Get ahead of 2026 reporting pressure
Set up templates, responsibilities, and checks now so your 2026 reporting is routine rather than reactive. An independent sustainability advisory can align fuel data, procurement evidence, and scheme claims into one audit ready workflow.
Conclusion
These template updates are small on paper but meaningful in practice. They reward operators who invest in data governance and traceable SAF claims, and they make compliance a pathway to credibility in the market.
Why this angle works: it frames the update as an operational advantage that improves audit clarity and reduces rework, which keeps the tone positive without sounding promotional.
Alternative approach: write the post as a short case style story showing how a reporting team uses negative entries to correct fuel safety tanking and uses the new claim fields to prevent double claiming during an internal audit.
