Climate change is considered as the most important contemporary global environmental problem. Despite research efforts from the social sciences to understand how individuals perceive the problem, few studies have focused on policy makers, specially in developing countries. This study seeks to determine the similarities and differences between elite government groups in Peru. It focuses on the knowledge about climate change, environmental concern, and sources of policy information, and how these factors affect policy preferences. Studies in other countries reveal that these factors can influence both the prioritization of environmental policy issues and the content of policy proposals. © 2011 Copyright Taylor and Francis Group, LLC.
