Refueleu aviation: new regulation for sustainable aviation

The European Union is working towards a 55% emissions reduction by 2030 through the Fit for 55 package. An important part of this package is Regulation (EU) 2023/2405, better known as ReFuelEU Aviation, which was adopted on 31 October 2023. 

This regulation aims to make the aviation sector more sustainable by: 
• Promoting the use of Sustainable Aviation Fuel (SAF) 
• Limiting fuel tankering (carrying extra fuel to refuel more cheaply elsewhere) 
• Improving transparency and reporting on fuel use 

Normec Verifavia supports aviation organisations with independent verification of emissions and fuel data, so you can comply with the regulation and report with confidence. 

Our approach

Normec Verifavia has extensive experience in validation, verification, and auditing within the aviation sector. Our specialists perform a thorough assessment of emissions data and operational parameters. 

This allows you to:

  1. 1.

    Comply with European regulations

  2. 2.

    Report transparently on fuel use

  3. 3.

    Minimise compliance risks

  4. 4.

    Build trust with regulators and stakeholders

With more than 10 years of experience in aviation verification, we provide reliable and accurate verification services. 

Who must comply with Refueleu aviation?

The ReFuelEU Aviation regulation applies to various parties within the aviation sector: 
• Aircraft operators 
• Aviation fuel suppliers 
• EU airports 
• Airport managing bodies 

An aircraft operator falls under the regulation when, in the previous reporting period, it operated: 
• At least 500 commercial passenger flights, or 
• At least 52 cargo flights departing from airports within the European Union. 

An EU airport is an airport that annually handles: 
• More than 800,000 passengers, or 
• More than 100,000 tonnes of cargo. 

What does ReFuelEU Aviation mean in practice for your organisation? 
• You must report on fuel use and SAF usage 
• You must comply with minimum shares for Sustainable Aviation Fuel (SAF) 
• You must prevent the same SAF from being counted multiple times under different schemes 
• You must submit reports via the EASA Sustainability Portal 
• You must provide transparent and verifiable data 

Expertise in aviation emissions and verification

Normec Verifavia is a globally recognised organisation for emissions verification in the aviation sector. 

Our experts have in-depth knowledge of: 
• Emissions and fuel reporting 
• European aviation regulations 
• Monitoring methodologies and control systems 
• Verification according to international standards 

During verification, we review, among other things: 
• Flight data and fuel consumption 
• Monitoring methodologies 
• Internal control systems 
• Consistency and completeness of reports 

Verification is carried out in accordance with ISO 17029:2019 and ISO 14065:2020, ensuring an independent and reliable verification process.

Prepared for the future of sustainable aviation

The aviation sector is undergoing a major transition towards lower emissions and more sustainable fuels. With ReFuelEU Aviation, the European Union is taking an important step towards a future in which Sustainable Aviation Fuel (SAF) plays a central role. 

By organising your reporting and verification properly, you can not only comply with regulations but also contribute to a more sustainable and transparent aviation sector.

Frequently asked questions

ReFuelEU Aviation is a European regulation that promotes the use of Sustainable Aviation Fuel (SAF) and requires airlines to report transparently on fuel use and emissions.

The regulation applies to:
- Aircraft operators
- fuel suppliers
- EU airports
- Airport operators

When certain thresholds for flights or passengers are exceeded, organizations are subject to the obligations of the regulation.

Sustainable aviation fuel (SAF) is a more sustainable type of aviation fuel produced from renewable resources or waste. SAF can significantly reduce lifecycle CO₂ emissions compared to conventional kerosene.

Refueling means that aircraft carry extra fuel to refuel more cheaply elsewhere. However, this increases the weight of aircraft, leading to higher fuel consumption and emissions. ReFuelEU Aviation therefore wants to restrict this practice.

A key deadline is March 31. Before this date, aircraft operators must submit their annual report through the EASA Sustainability Portal.

In some cases, aircraft operators can apply for temporary exemptions, such as for certain short routes or airports on islands without rail or road connections.

Normec Verifavia supports organizations with:
- Independent verification of fuel and emissions data.
- Review of reports and monitoring methods
- Preparation of verification reports
- Guidance on compliance with European regulations

The ReFuelEU Aviation regulation applies to aircraft operators operating flights from EU airports. The obligations apply when an operator has performed at least the following in the previous reporting period (January 1 - December 31)
- 500 commercial passenger flights, or
- 52 commercial cargo flights operated from EU airports.

Aircraft operators must ensure that flights departing from EU airports have sufficient fuel for the planned flight.
According to Article 5 of the ReFuelEU Aviation regulation, the total annual amount of fuel refueled at a specific EU airport must be at least 90% of the operator's total fuel requirements at that airport.
This requirement is intended to prevent fuel refueling.

According to Article 8 of the ReFuelEU aviation regulation, aircraft operators must submit an annual verified report to the competent authority.
The first report must be submitted in 2025 and annually thereafter by March 31 (year N+1). The report shall include:

The report shall include:

Fuel report
- Total number of flights from EU airports
- Total number of flight hours from EU airports
- Total annual fuel requirements (travel fuel and cab fuel) by EU airports
- Total amount of fuel refuelled per EU airport
- Annual amount of fuel not refuelled
- Amount of additional fuel refuelled for safety reasons

SAF procurement report
- Total amount of aviation renewable fuel (SAF) purchased for regulated flights
- Details per SAF purchase, such as
o supplier
o Lot number
o Quantity (tons)
o Fuel category
o Raw materials used
o Life cycle emissions
- SAF claimed under schemes such as:
o EU ETS
o CH ETS
o CORSIA
o Other market-based measures
- SAF not claimed under other schemes

Declaration
The operator must declare that the same SAF lots have not been claimed multiple times under different emission schemes.

Starting in 2025, fines may be imposed if an operator fails to comply with the obligations under Article 5, including the requirement for at least 90% fuel refueling.
The amount of fines will be determined by member states, but will be at least
twice the average annual fuel price × the total amount of fuel not refueled.

In some cases, fuel may be refueled to meet the safety requirements of Commission Regulation (EU) No. 965/2012.
Examples include situations such as:
- Fuel shortage at the destination
- Fuel contamination at the destination (confirmed through a NOTAM)
- Operational restrictions at certain airports, such as:
o Very long transit times
o Limited airport capacity during peak hours

In such cases, the operator should indicate in the report which airports and flights are affected.

No. The obligation to offer a minimum proportion of Sustainable Aviation Fuel (SAF) lies with the fuel suppliers at EU airports.
The obligations on aircraft operators focus mainly on preventing refueling.
Because fuel suppliers are required to blend SAF into their fuel supply, in practice operators will fill up with fuel that contains a minimum SAF share.
