Business aviation: evidence for the EU taxonomy

A bank asks you to substantiate the environmental characteristics of a business aircraft. Before sending its maintenance file, ask which criterion it wants to check: actual fuel consumption, use of sustainable fuel or an activity covered by the EU taxonomy. These questions require different evidence.

The EU taxonomy classifies economic activities against environmental conditions. It is not a label attached to each aircraft. For an owner or fleet manager, the first useful step is to obtain a written request identifying the activity being assessed and the method used.

What the Dassault judgment establishes

On 24 June 2026, the EU General Court delivered its judgment in Case T-77/24, Dassault Aviation v Commission. The operative part published in the Official Journal on 10 August 2026 annuls Section 3.21 on aircraft manufacturing, which Regulation 2023/2485 had inserted into Regulation 2021/2139.

The dispute concerned the exclusion of business aircraft from that manufacturing activity. The Court's press release explains the error of assessment found. When describing the legal outcome, however, the scope of the operative part matters: the section is annulled, rather than a word simply being removed from a list of exclusions.

This decision therefore does not provide blanket approval for business jet operations or a loan to purchase one. Before applying manufacturing criteria to a real file, have the applicable text and subsequent developments in the case confirmed as of the assessment date.

The general framework is Regulation (EU) 2020/852, Article 3. It combines several conditions: contributing substantially to an environmental objective, doing no significant harm to the others, meeting minimum safeguards and complying with applicable technical screening criteria. A favourable fuel consumption figure alone does not demonstrate that all these conditions are met.

Build the evidence around the question

The following is a preparation method. It is not a universal list of records required by every bank.

1. Record the requested criterion. Keep the questionnaire, its version, the period assessed and the name of the person reviewing the answer. Distinguish a regulatory criterion from a condition specific to the financing agreement.
2. Identify the aircraft. Reconcile its identity, engines, installed equipment and relevant modifications. This establishes whether a manufacturer's data relates to the aircraft under review.
3. Choose the right technical evidence. ICAO, the International Civil Aviation Organization, distinguishes engine emissions in Annex 16 Volume II from aeroplane CO₂ emissions in Volume III. These are not interchangeable references to engine emissions. Request the document relevant to the criterion, with its version.
4. Document an operational claim. For reported fuel consumption, specify the period, flights included and calculation method. For SAF, sustainable aviation fuel, connect the quantity claimed to delivery and sustainability evidence appropriate to the method used. An intention to purchase does not prove delivery.

EASA publishes ReFuelEU Aviation reporting and verification documents. They concern that regulation and its scope. Using them does not automatically turn a fuel declaration into proof of taxonomy alignment.

What airworthiness records contribute

The CAMO, continuing airworthiness management organisation, manages the ongoing work needed to keep an aircraft fit to fly under the applicable rules. Its framework is Regulation (EU) 1321/2014.

Its records can help check the technical configuration used in an environmental statement. They replace neither the fuel supplier's evidence nor the lender's assessment. A weighing report or modification history also does not prove that the aircraft's original performance has remained identical in all conditions.

If two records show different weights, first check their definitions, dates and the equipment included. The discrepancy needs an explanation; it does not establish an automatic rule of rejection by a bank.

A fictional example: answer without overpromising

An owner is preparing a refinancing application. They attach a recent brochure, an old weighing report and an intention to purchase SAF. The lender, however, asks for observed fuel consumption over a specific period.

The manager clarifies the expected period and method. They gather the corresponding flight and fuel data, explain any gaps and check with the CAMO that the assumed configuration matches those flights. The intention to purchase SAF remains identified as an intention.

The file now answers a verifiable question. The financing decision and assessment of the other criteria remain with the people responsible for them.
