Wind energy under the EU Taxonomy

Like solar, electricity generation from wind qualifies as a substantial contribution to climate change mitigation by its nature, with no emissions threshold. The assessment weight sits in Do No Significant Harm, and it differs sharply between onshore projects, where biodiversity and siting dominate, and offshore, where marine environment requirements apply.

Why this activity matters

Wind is the largest source of renewable electricity in the EU and a mainstay of green financing: wind portfolios anchor green bonds, sustainability-linked facilities and Article 9 funds. The Taxonomy recognises the technology’s mitigation contribution outright, so eligibility and substantial contribution are rarely contested. What separates a clean alignment from a qualified one is the environmental evidence around the specific site.

Onshore, the recurring issues are bird and bat sensitivity, proximity to protected areas, and the quality of the environmental impact assessment. Offshore, the criteria additionally reference the marine environment, bringing seabed condition, noise during construction, and conformity with marine spatial planning into scope. Lenders and investors increasingly ask for this evidence at diligence, which is exactly what a structured assessment surfaces.

What alignment requires

Substantial contribution is met by the activity itself; the substantive tests are DNSH, with an extra marine dimension offshore. In summary:

Area	What is required (summarised)
Substantial contribution	The activity generates electricity from wind power. No life-cycle emissions threshold applies.
Biodiversity (DNSH)	EIA where applicable; for sites in or near sensitive areas, appropriate assessment with mitigation. Bird and bat collision risk and habitat impacts are the typical onshore focus.
Marine environment (offshore)	Offshore installations must additionally evidence that they do not hamper good environmental status of marine waters, including construction noise management and seabed considerations.
Circular economy (DNSH)	Durability and end-of-life management, with blade recyclability the emerging documentation point.
Climate adaptation (DNSH)	CRVA over the asset life, covering storm intensity, icing and, offshore, wave and current conditions.

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

Where DNSH scrutiny falls

Biodiversity (onshore)

Bird/bat surveys, protected-area proximity, and the EIA outcome carry the assessment; post-consent monitoring commitments strengthen it.

Marine environment (offshore)

Underwater noise during piling, seabed disturbance, and alignment with marine spatial plans are the offshore-specific asks.

Circular economy

Turbine end-of-life arrangements and blade recycling routes are increasingly requested by assessors and lenders.

Climate adaptation

Site-specific CRVA; offshore assets should address metocean conditions over the operating life.

Documentation that typically supports the assessment

Site location / coordinates (onshore) or lease area (offshore)
EIA and, where relevant, appropriate assessment and derogation documentation
Bird and bat survey results and mitigation plans (onshore)
Marine licence, noise management plan and seabed assessments (offshore)
Climate risk and vulnerability assessment
Decommissioning and end-of-life arrangements

How Censatim assesses it

Our first question establishes onshore versus offshore, because the DNSH evidence differs materially. From there the assessment targets the environmental documentation for the specific site, and the rating confidence tracks the quality of the EIA and survey evidence provided. Wind assessments with a complete environmental file typically reach high-confidence conclusions quickly.

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

Is wind power automatically aligned under the EU Taxonomy?

Wind automatically meets the substantial contribution criterion, since electricity generation from wind power is recognised without an emissions threshold. Full alignment still requires the DNSH criteria and Minimum Safeguards, and for wind the decisive evidence is environmental: biodiversity onshore, the marine environment offshore.

What is different about offshore wind under the Taxonomy?

Offshore projects face an additional DNSH dimension: they must not hamper the good environmental status of marine waters. In practice that means evidencing construction noise management, seabed impact consideration, and consistency with marine spatial planning, alongside the standard criteria.

Do bird and bat surveys matter for Taxonomy alignment?

Yes, for onshore wind they are often the decisive DNSH evidence. The biodiversity criterion requires environmental assessment and mitigation where sites are in or near sensitive areas, and collision risk for birds and bats is the standard focus of that assessment for wind.

Can an existing operating wind farm be assessed, or only new projects?

Both. Operating assets are assessed on their environmental documentation and any monitoring history; new projects on their consenting evidence. Investors typically assess operating portfolios for green bond and SFDR reporting, and developers assess projects at financing.
