Preventive Environmental Impact Assessment Purpose
Environmental Impact Assessment (EIA) is a preventive procedure intended to inform project developers about the environmental impacts that implementation may generate. It serves as a precautionary measure and a corrective procedure for planning, aiming to mitigate negative effects at the core of a project. Furthermore, it assists in decision-making by defining and proposing mitigation measures to offset or even cancel potential environmental changes. In this context, it informs the government of the environmental effects of specific actions and decisions, functioning as a preventive instrument.
Strategic Environmental Assessment (SEA) Mechanisms
The Strategic Environmental Assessment (SEA) is a mechanism for environmental integration. It is a modern tool that complements, rather than substitutes, the EIA. It represents an advanced demonstration of prevention policies aimed at sustainable development. While EIA and SEA are distinct in their spatial and temporal scopes, as well as their content and effects, they work together effectively.
Comparing EIA and SEA Frameworks
The EIA is more detailed and specific, focusing on individual projects. However, the existence of SEA requirements makes the EIA more effective, as the SEA establishes default environmental alternatives. The SEA incorporates environmental considerations into the preparation of plans and programs to achieve high-level protection by promoting social, economic, and environmental sustainability. This process ensures transparent public participation in the information provided and the final decisions taken.
Legal Framework and Directive 2001/42/EC
The current legal regime is determined by Directive 2001/42/EC, which introduced the evaluation of effects for specific environmental plans and programs. In the Spanish context, Law 9/2006 of April 28, regarding the evaluation of the effects of certain plans and programs on the environment (BOE No. 102 of April 29, 2006), regulates the implementation and transposition of the Strategic Environmental Assessment. The following observations can be made:
