An Environmental Impact Assessment (EIA) is not only a legal requirement, it is also a key tool for ensuring that projects are developed in harmony with nature and communities. In Spain, EIAs are regulated by Law 21/2013 on Environmental Assessment, which incorporates European regulations and establishes the procedures to be followed for public and private projects.
The EIA process includes:
1️⃣ Initial diagnosis
Delimitation of the area of influence and detection of environmental and social elements that could be affected.
2️⃣ Baseline
Collection of detailed information on fauna, flora, water, soil, landscape, cultural heritage and local communities before the start of the project.
3️⃣ Identification of impacts
Analysis of the possible positive and negative, direct and indirect, cumulative and synergistic effects of the work or activity.
4️⃣ Management and mitigation measures
Definition of actions to prevent, correct, reduce or compensate for impacts, including environmental restoration and compensation plans.
5️⃣ Follow-up and monitoring
Control of compliance with the established measures and evaluation of the evolution of ecosystems over time.
The Spanish framework
? The ordinary EIA applies to larger projects (motorways, reservoirs, large industries, etc.), with a more detailed procedure and mandatory public participation.
? The simplified EIA applies to projects with potentially minor impacts, where the environmental authority determines whether a more in-depth assessment is necessary.
? Public participation is a central element: projects must be subject to public information and consultation with the competent authorities.
Beyond the legal requirement
✅ A well-structured EIA in Spain not only protects the environment, but also facilitates decision-making, reduces social and legal conflicts, and builds confidence in projects.
The challenge lies in applying it with rigour and commitment, ensuring that economic development goes hand in hand with the protection of biodiversity and the well-being of communities.
