This article assesses the quality of the contents and the validity of the conclusions of the book "The Skeptical Environmentalist" by Bjørn Lomborg. First, the many reviews - both critiques and appraisals - are summarized and evaluated. Next, Lomborg's responses to criticisms are examined. Finally, the consistency of the book with certain insights from the field of environmental economics is investigated. This complements for an under-representation of environmental economists among the reviewers, even though the book addresses themes central to this field. © 2010 Taylor & Francis.
