EIA 2011/92/EU: environmental consent before breaking ground

Environmental Impact Assessment is a prerequisite for development consent for all projects listed in Annex I, and for Annex II projects where screening confirms significant effects. Yet many industrial operators misclassify their projects, underestimate public consultation timelines, or submit Environmental Impact Statements with incomplete baseline data — triggering delays, challenges, and infringement proceedings.

Annex I

projects always require a full EIA — no screening, no discretion. Oil refineries, integrated chemical installations, major infrastructure. Consent without EIA is void.

Annex II

projects require screening by the competent authority using Annex III criteria: size, location (proximity to protected areas), and nature of potential impact.

Art. 6

mandates public participation: the public concerned must be informed and consulted before development consent is given. Minimum 30-day comment period under many national transpositions.

The environmental and legal team spends weeks determining whether a project triggers EIA, what the Environmental Impact Statement must contain, and how to manage public consultation and transboundary notification. IgeraIndustria answers those questions in seconds, citing the exact EIA article or annex, so the project team can focus on obtaining consent on time.

Instant EIA compliance query by project type

IgeraIndustria locates the exact EIA requirement that applies to each project and responds with the applicable annex, screening criteria, Environmental Impact Statement content obligations, and the consultation steps required before development consent.

Annex I vs Annex II classification

The classification of a project under Annex I or Annex II determines whether EIA is mandatory or subject to screening. IgeraIndustria identifies the correct annex for your project type and explains the implications — including whether capacity thresholds in Annex I are met and how cumulation with other projects is assessed.

Screening procedure for Annex II projects

For Annex II projects, the competent authority must conduct a screening determination using the selection criteria in Annex III: project characteristics (size, production of waste, pollution), location (environmental sensitivity, proximity to Natura 2000 areas), and type and characteristics of potential impact. IgeraIndustria guides teams through the screening submission.

Environmental Impact Statement content

Article 5 and Annex IV set out the mandatory content of the EIS: project description, reasonable alternatives, baseline environment, likely significant effects on all receptors, mitigation measures, monitoring programme, and non-technical summary. IgeraIndustria identifies gaps in draft EIS documents and flags missing mandatory elements.

Public consultation and participation

Article 6 requires that the public concerned be given early and effective opportunity to participate. The EIS must be made available and a public comment period must be observed before development consent is granted. IgeraIndustria explains the consultation obligations and the consequences of procedural defects for the validity of consent.

Transboundary EIA under Article 7

When a project is likely to have significant effects on another EU Member State, Article 7 requires notification and consultation of the affected Member State and its public. IgeraIndustria identifies when transboundary EIA is triggered, the notification timeline, and the documentation requirements under Espoo Convention obligations.

EIA interaction with Natura 2000 (Habitats Directive)

Projects near Natura 2000 sites may trigger both EIA under Directive 2011/92/EU and Appropriate Assessment under the Habitats Directive 92/43/EEC. IgeraIndustria explains how the two procedures interact, the higher standard of protection for Natura 2000, and the conditions under which a project may proceed despite adverse effects on site integrity.

Complete EIA 2011/92/EU compliance support

From project screening to Environmental Impact Statement preparation and public consultation management, IgeraIndustria supports the environmental and legal team at every stage of the EIA procedure.

Scoping and early engagement

Article 5(2) allows developers to request a scoping opinion from the competent authority to determine the information to be included in the EIS. IgeraIndustria helps structure the scoping request, identifies which environmental receptors require detailed study, and flags site-specific sensitivities that will be scrutinised.

Baseline data gap analysis

A robust baseline is the foundation of a defensible EIS. Competent authorities and courts have quashed consents where baseline data was insufficient. IgeraIndustria identifies gaps in baseline surveys, missing seasonal data for ecology, inadequate air quality or noise monitoring periods, and incomplete hydrogeological characterisation.

Alternatives assessment

Article 5(1) and Annex IV require that the developer describe reasonable alternatives studied and the main reasons for the option chosen, having regard to environmental effects. IgeraIndustria explains what constitutes a genuine alternatives assessment and the level of comparative detail required to withstand legal challenge.

Mitigation and monitoring measures

The EIS must describe mitigation measures to avoid, reduce, or offset significant adverse effects. IgeraIndustria helps structure the mitigation hierarchy (avoid, minimise, restore, offset), the monitoring programme design, and the conditions that competent authorities typically impose as development consent conditions.

Retroactive EIA and regularisation

CJEU case law (C-201/02 Wells, C-215/06 Commission v Ireland) establishes that regularisation of projects built without required EIA is permissible only if all significant effects are assessed retrospectively — and demolition may be required if they cannot be. IgeraIndustria analyses the regularisation risk and the steps required under national transposition.

EIA decision and development consent

Article 8 requires that the results of consultations and the information gathered are taken into consideration in the development consent procedure. The competent authority must give a reasoned conclusion on the significant effects of the project. IgeraIndustria explains the procedural requirements and how to respond to authority objections during the consent stage.

The 4 pillars of EIA 2011/92/EU compliance

These pillars define what developers must demonstrate before development consent is granted for projects subject to the EIA Directive.

Pillar 1 — Project classification (Annex I / Annex II)

The developer must correctly classify the project under Annex I (automatic EIA) or Annex II (screening). Misclassification that avoids EIA renders development consent void under EU law. Thresholds in Annex I are absolute; for Annex II, the competent authority applies Annex III selection criteria. Phased projects or modifications to existing projects may also trigger EIA under Article 4(2).

Pillar 2 — Environmental Impact Statement (EIS)

The EIS is the central document of the EIA procedure. It must contain all information specified in Annex IV that the developer can reasonably be required to compile, having regard to current knowledge and methods of assessment. The EIS must be prepared by competent experts and include a non-technical summary accessible to the general public.

Pillar 3 — Public and authority consultation

Articles 6 and 7 require consultation of the public concerned (those affected by, or having an interest in, the project) and statutory consultees (environmental authorities). The public must have access to the EIS and the developer’s responses. Consultation must be effective and timely — not a formality — and its results must be taken into account in the development consent decision.

Pillar 4 — Reasoned conclusion and monitoring

The competent authority must issue a reasoned conclusion on the significant effects of the project, integrating the EIS, consultation results, and any supplementary information. The development consent decision must include conditions requiring monitoring of significant adverse effects, so that corrective measures can be taken. Post-consent monitoring reports must be made publicly available.

Environmental Manager

Our biomass plant will have an installed capacity of 250 MW. Does it require a mandatory EIA under Annex I or only screening under Annex II of Directive 2011/92/EU?

IgeraIndustria

EIA 2011/92/EU — Biomass Plant Classification

Your 250 MW biomass plant:

• Annex I, point 2: thermal power stations and other combustion installations with a heat output of 300 MW or more — your plant at 250 MW is below the Annex I threshold
• Annex II, point 3(a): industrial installations for the production of electricity that are not covered by Annex I — screening required

Screening considerations for your site:

• Check proximity to Natura 2000 sites — this is a key Annex III criterion that can convert an Annex II project to mandatory full EIA
• Fuel supply chain (transport, storage) and air quality impacts (PM, NOx) will be assessed in screening

⚠️ Request a scoping opinion from the competent authority under Art. 5(2) before starting the EIS — this reduces risk of gaps at submission

Frequently asked questions — EIA Directive 2011/92/EU

What is the difference between Annex I and Annex II projects under the EIA Directive?

Annex I projects always require a full EIA — these are projects with significant effects on the environment by their nature: oil refineries, thermal power stations >300 MW, integrated steelworks, integrated chemical installations, motorways and express roads, airports with runways >2,100m, hazardous waste disposal installations, groundwater abstraction >10 million cubic metres/year, and pulp mills >200 tonnes/day. Annex II projects are subject to a screening procedure: the competent authority determines case-by-case, using selection criteria (size, location, characteristics of potential impact) in Annex III, whether a full EIA is required.

What must an Environmental Impact Statement contain?

Under Article 5 and Annex IV of the EIA Directive, the Environmental Impact Statement must include: a description of the project (physical characteristics, land-use requirements during construction and operation); a description of reasonable alternatives studied; a description of current state of the environment (baseline) including evolution if no project; a description of likely significant effects (population, human health, biodiversity, land, soil, water, air, climate, material assets, cultural heritage, landscape and interactions); mitigation measures; monitoring measures; a non-technical summary; and references to expertise used.

Does the EIA Directive apply to projects that have already started?

The EIA Directive applies to development consent for new projects. However, the Court of Justice of the EU has consistently held that regularisation of projects already completed or under construction is not permitted by EIA law — the assessment must precede development consent. If a project started without EIA when one was required, the competent authority must require regularisation (retroactive EIA) and may need to order suspension or even demolition if the project cannot be regularised. This has been applied in multiple infringement proceedings against Spain and other Member States for unauthorised projects in sensitive areas.
