Obtaining reliable information is essential to forming a balanced understanding of the scope and complexity of environmental sustainability, and it is essential for effective participation, decision-making, and research in sustainability-related activities. While the ACRL Standards for Information Literacy (2000) are a good guiding principle for obtaining needed information, they must be applied in conjunction with other standards and principles in order for students to obtain all the necessary skills to become information literate, lifelong learners. Though they come from traditionally unrelated fields, the principles of evidence-based practice mirror the ACRL standards, and applying these methods to sustainability reference interviews has the potential to increase the science literacy of students who otherwise lack background knowledge in the sciences.
