Assessing environmental licensing guidelines for wind energy in Brazil: implications for biodiversity conservation

Area of Science:

• Environmental Science
• Renewable Energy Policy
• Conservation Biology

Background:

• Wind energy is crucial for climate change mitigation and energy security.
• Brazil is a major global wind energy producer, with high demand in the Northeast.
• Current environmental licensing for wind energy in Brazil has limitations in protecting vulnerable species.

Purpose of the Study:

• To evaluate the quality of environmental licensing guidelines for wind energy projects in nine northeastern Brazilian states.
• To assess the adequacy of these guidelines in addressing the conservation needs of birds, amphibians, and reptiles.

Main Methods:

• An analytical checklist with 66 guiding questions was used.
• Guidelines were assessed based on recommendations for data collection on birds, amphibians, and reptiles.
• Nine northeastern Brazilian states were included in the evaluation.

Main Results:

• Six states with specific wind energy licensing guidelines demonstrated higher quality indicators.
• States relying on general or non-specific regulations showed lower performance in environmental protection.
• Significant variations in guideline quality were observed across the evaluated states.

Conclusions:

• Urgent revision of environmental licensing guidelines for wind energy is recommended across all nine states.
• Guidelines must be clear, comprehensive, and mandate primary data collection on birds, amphibians, and reptiles.
• Improved licensing will enhance biodiversity conservation and promote ecologically sustainable wind energy development.
