Bjørn Lomborg is a well-known personality in the environmental debate. He is the author of several books which, due to their copious lists of notes and references, appear very technical and scientific and therefore trustworthy. Unfortunately, those reading his books or listening to his lectures or seeing his film are rarely aware that the facts and statements presented by Lomborg are often not reliable.
     When experts in the fields covered by Lomborg check his texts, they most often find that the evidence has been distorted. Danish biologist Kåre Fog has systematically over many years checked Lomborg´s texts against his sources and references and against other scientific literature. His conclusion is that Lomborg´s texts are systematically manipulated to fit a certain agenda.
     The web site Lomborg-errors
  has been established to document this claim. It gathers and publishes errors found in Bjørn Lomborg´s books, especially  "The Skeptical Environmentalist" (2001) and Cool it! (2007).
     In addition, it gives information on cases and activities related to Bjørn Lomborg, attempts to describe his methods, and points out cases where the claims about Lomborg´s dishonesty seem to hold true.
     From January 2008, the page also comments on errors made by Al Gore, to allow a comparison where the two persons are judged by the same standards.
    The web site is set up by, written by and hosted by Kåre Fog.

Purpose : 

   The purpose of this web site is not to present a comprehensive overview of the issues treated by  Bjørn Lomborg, but only to point out errors - as the name of the web site indicates.
   Why is it essential to point out the errors?
   First, because in the handling of errors, Lomborg does not act like most persons would do. A normal person would apologize or be ashamed if concrete, factual errors or misunderstandings were pointed out - and would correct the errors at the first opportunity given. Lomborg does not do that.  For example, when  The Skeptical Environmentalist was heavily  criticized in a review  in Nature, Lomborg´s reaction was: "
If I really am so wrong, why don´t you just document that?" - and then, when this was documented, he ignored the facts. Read more about Lomborg´s reaction to criticism here.
   Second, because you cannot evaluate Lomborg´s books just by reading them and thinking of what you read. For every piece of information in the books, you have to check if it is true and if the presentation is balanced. If the concrete information given by Lomborg is correct and balanced, then it follows that his main conclusions are also correct. But if the information is flawed, then the main conclusions are biased or wrong. Therefore, in principle, you can only evaluate the books after having checked all footnotes, read all references, and checked alternative sources. This will be a huge task for any reader, but when the errors are described and presented in one place - this web site - then the task becomes manageable.
   Third, because the errors seem not to be inadvertent, but to follow a general pattern, they give a bias in a certain direction, probably an intended bias. If the errors remain uncommented, the readers of Lomborg´s books will be misled in this distinct direction . There are many examples where the misleading seems to be deliberate, which indicates that Lomborg is dishonest and covers up a hidden agenda. If this is so, then this has consequences for the understanding of  Lomborg´s intentions. The question whether the misleading is deliberate is discussed in more detail here.
