Significant Indirect Environmental Effects under the EIA Directive: An Taisce v An Bord Pleanála & ors (Rev1) [2022] IESC 8

Introduction

The Supreme Court of Ireland delivered its judgment on An Taisce - The National Trust for Ireland v An Bord Pleanála & ors (Rev1) [2022] IESC 8 on February 16, 2022. This landmark case addresses the obligations of environmental impact assessments (EIA) under the European Union's EIA Directive, particularly focusing on the assessment of indirect environmental effects of a proposed development project.

Parties Involved:

Appellant: An Taisce - The National Trust for Ireland, a non-governmental organization dedicated to environmental conservation.
Respondents: An Bord Pleanála (the Irish Planning Board), the Minister for Communications, Climate Action and the Environment, the Attorney General, and Kilkenny Cheese Limited.

Case Background:

The appellant challenged a decision by An Bord Pleanála to grant planning permission for constructing a major cheese factory in Slieverue, Co. Kilkenny. The core issue revolved around whether the planning authority had adequately assessed the indirect environmental effects of the factory, particularly the increased milk production required to supply the facility and its consequent impact on greenhouse gas (GHG) emissions.

Summary of the Judgment

The Supreme Court upheld the decision of the High Court to dismiss An Taisce's application for judicial review. The Court found that the Planning Board had fulfilled its obligations under both the EIA Directive and the Habitats Directive. Specifically, the Board determined that the construction and operation of the cheese factory would not lead to significant indirect environmental effects since the increased milk production was projected to occur regardless of the factory's establishment, largely due to existing productivity gains and national climate policies.

The Court emphasized that while the project's indirect effects on milk supply and emissions were acknowledged, they did not constitute "significant indirect effects" within the meaning of the EIA Directive. Furthermore, the Court rejected the need to assess impacts beyond the direct relationship between the project and its immediate environmental effects.

Analysis

Precedents Cited

The judgment referenced several key cases that influenced the Court's decision:

Fitzpatrick v. An Bord Pleanála [2019] IESC 23: Established that the EIA Directive applies strictly to the project for which planning permission is sought.
Ó Grianna v. An Bord Pleanála [2014] IEHC 632: Highlighted the necessity of assessing projects with interdependent off-site activities.
An Taisce v. An Bord Pleanála [2015] IEHC 633 (Edenderry): Determined that environmental effects of a project's off-site activities can fall within the EIA Directive if they are sufficiently interdependent.
R.(Finch) v. Surrey County Council [2020] EWHC 3566 (Admin): Clarified that indirect effects must be directly linked to the project.
Greenpeace Limited v. The Advocate General [2021] CSIH 53: Reinforced the principle that only effects directly connected to the project are subject to EIA.
People over Wind (Case C-323/17): Affirmed that national authorities must not allow deterioration of water quality despite granted permissions.

Legal Reasoning

The Court meticulously analyzed the EIA Directive's provisions, focusing on the definition of a "project" and the scope of "significant indirect effects." The key points include:

Definition of Project: The EIA Directive defines a project as the execution of construction works or other interventions. In this case, only the cheese factory constituted the project.
Indirect Effects: The Court determined that indirect effects must be directly related to the project. The projected increase in milk production was deemed an independent economic trend rather than a direct consequence of the factory's construction.
Remoteness and Feasibility: Given the impracticality of assessing the environmental impact of 4,500 independent dairy farms, the Court favored a narrow interpretation to avoid an open-ended obligation.
HHarmful Effects: The potential environmental impacts, such as increased GHG emissions from higher milk production, were already accounted for in national policies and mitigation measures.

Impact

This judgment reinforces the principle that EIA assessments under the EIA Directive should remain tightly connected to the specific project in question. It prevents the broad expansion of EIA scopes that could render environmental assessments unmanageable. Future cases involving large-scale projects with significant indirect effects will likely refer to this precedent to limit EIA obligations to directly linked environmental impacts.

Moreover, the decision underscores the importance of national policies and sectoral measures in addressing broader environmental concerns, such as climate change, rather than overburdening EIA processes with extensive indirect effect assessments.

Complex Concepts Simplified

Environmental Impact Assessment (EIA) Directive

The EIA Directive is a European Union law that requires environmental assessments for projects likely to have significant environmental effects. Its primary goal is to ensure that potential environmental impacts are considered before the project proceeds.

Direct vs. Indirect Environmental Effects

Direct Effects: Immediate and tangible impacts resulting from a project, such as pollution from factory emissions.

Indirect Effects: Secondary or consequential impacts that occur as a result of the project, like increased demand for milk leading to higher GHG emissions from dairy farming.

Significant Indirect Effects

These are indirect impacts that are substantial enough to warrant evaluation within the EIA process. However, as established in this case, only effects directly tied to the project should be assessed to avoid overly broad and impractical evaluations.

Remoteness

This refers to the distance or separation between the project and its indirect effects. The Court emphasized that effects must not be too remote to be considered significant and relevant to the project.

Conclusion

The Supreme Court's decision in An Taisce v An Bord Pleanála & ors (Rev1) clarifies the boundaries of environmental impact assessments under the EIA Directive. By affirming that only directly linked indirect effects should be considered, the Court ensures that EIAs remain practical and focused on the immediate environmental consequences of projects.

This judgment underscores the necessity of maintaining a clear delineation between project-specific impacts and broader economic or sectoral trends. It also highlights the role of national policies in mitigating environmental concerns, ensuring that EIA processes do not become overextended in addressing issues beyond their intended scope.

For practitioners and stakeholders, this case serves as a pivotal reference point in understanding the limits of EIA obligations, particularly in complex projects with potential widespread indirect effects.
