Aviation under the EU Taxonomy

Aviation’s criteria acknowledge an awkward truth: zero-emission aircraft barely exist yet. So the Taxonomy rewards the transition mechanics instead: manufacturing and operating best-in-class aircraft that replace older tonnage, escalating sustainable aviation fuel shares, and zero-emission ground operations, all under transitional, time-limited conditions that make assessments date- and evidence-sensitive.

Objective

Climate change mitigation

Sector

Transport

Aviation entered the Taxonomy in the 2023 amendments as a transitional package with unusually intricate conditions: best-in-class aircraft qualify only alongside fleet-replacement commitments and escalating sustainable aviation fuel use, and much of the framework is explicitly time-limited.

Why this activity matters

Aviation is among the hardest sectors to decarbonise, and its Taxonomy treatment was correspondingly contested. The framework that emerged covers aircraft manufacturing, leasing and air transport operations, with a common architecture: zero direct emission aircraft qualify outright (a forward-looking provision), while conventional aircraft qualify transitionally only as best-in-class units, meeting the latest certification standards and a defined margin against fleet benchmarks, and only where they demonstrably replace older aircraft rather than expand capacity.

The operational overlay is sustainable aviation fuel: operators relying on transitional aircraft face escalating SAF-share commitments beyond regulatory minimums. For lessors and aviation financiers, this creates a genuinely assessable framework: aircraft technical data, delivery and retirement schedules, and SAF procurement evidence together determine the aligned share of a fleet or portfolio, and the time-limited nature of the criteria makes reassessment part of the lifecycle.

What alignment requires

A transitional package combining aircraft standards, replacement logic and fuel commitments. In summary:

Area	What is required (summarised)
Zero-emission aircraft	Aircraft with zero direct CO2 tailpipe emissions (electric or hydrogen propulsion) qualify outright across manufacturing, leasing and operation.
Best-in-class transitional	Conventional aircraft qualify only where they meet the latest certification standards with a defined efficiency margin against the global fleet benchmark, within time-limited windows.
Fleet replacement	Transitional qualification requires replacement: evidence that qualifying deliveries retire older aircraft on a defined basis rather than adding capacity.
SAF commitments	Operating transitional aircraft carries escalating sustainable aviation fuel share requirements beyond the regulatory baseline, evidenced by procurement and blending records.

Summarised for orientation; the assessment itself applies the full criteria text of the Delegated Acts as amended.

Where DNSH scrutiny falls

Pollution

Noise and local air quality: aircraft noise certification margins and NOx standards are the characteristic items.

Circular economy

End-of-life aircraft handling: dismantling, part-out and recycling arrangements.

Climate adaptation

CRVA proportionate to operations; infrastructure exposure for operators with owned ground assets.

Documentation that typically supports the assessment

Aircraft technical data: type, certification standards, efficiency metrics against the benchmark
Delivery and retirement schedules evidencing the replacement condition
SAF procurement, blending and sustainability certification records
Noise and emissions certification documentation
For lessors: portfolio schedules by aircraft type and lessee

How Censatim assesses it

Aviation is the most condition-dense transport assessment we run: our questioning walks the specific aircraft against the certification and benchmark requirements, tests the replacement evidence, and quantifies the SAF commitments, flagging clearly which conclusions are time-limited. Lessor portfolios are assessed aircraft by aircraft, which is also how the aligned share is reported.

Censatim is an expert-built EU Taxonomy assessment tool: describe the asset or activity in plain language, upload supporting documents, and answer a short set of targeted questions. The result is a criterion-by-criterion view with an In-line / Partial / Not aligned / Undetermined rating and a confidence level for each dimension. See the full methodology.

Frequently asked questions

Can conventional jet aircraft be EU Taxonomy aligned?

Only transitionally and conditionally: the aircraft must be best-in-class against the latest certification standards and fleet benchmarks, must demonstrably replace older aircraft rather than expand capacity, and operation carries escalating SAF commitments. The provisions are time-limited by design.

What are the SAF requirements in the Taxonomy aviation criteria?

Operators qualifying through transitional aircraft must use sustainable aviation fuel in shares that escalate over time beyond the regulatory minimums, evidenced through procurement and blending records with sustainability certification.

How does the fleet replacement condition work?

Transitional qualification is tied to replacement: qualifying deliveries must correspond to the retirement of older aircraft on the defined basis, so delivery and retirement schedules are core evidence. Capacity expansion with efficient aircraft does not by itself qualify.

Does aircraft leasing qualify under the EU Taxonomy?

Yes, leasing is a covered activity: lessors assess aircraft against the same standards, and the aligned share of a leasing portfolio follows from the aircraft-level results. This has made the criteria directly relevant to aviation finance structures.
