The Skeptical Environmentalist: Measuring the Real State of the World (Danish: Verdens sande tilstand, lit. 'The True State of the World') is a book by Danish author and statistician Bjørn Lomborg which focuses on the author's view of environmental economics and issues. It was first published in Danish in 1998 by Centrum, and in English by Cambridge University Press in 2001.
Lomborg was inspired by an interview with economist Julian Lincoln Simon to undertake an assessment of publicly available data, and published his findings as a series of articles in Politiken. These formed the basis of the book, in which Lomborg argues against a range of what he considers overly pessimistic claims about environmental issues and their impact on human prosperity. Lomborg argues that environmentalists' concerns over pollution, environmental degradation, decline in natural resources, and climate change are overstated, and outlines his opposition to policy responses like the Kyoto Protocol, deeming them insufficient and causing more harm than good based on cost–benefit analysis. He argues in favour of focus instead being channelled to poverty reduction and combating diseases.
The book generated great controversy and negative reviews upon its release. Lomborg's assertions, methodology and representation of sources were criticised by scientists and groups both in Denmark and internationally. Positive reception in some popular media outlets contrasted sharply with this, and this combined with the ensuing debate aided the book's profile.
The author was formally investigated by the Danish Committees on Scientific Dishonesty (DCSD) for scientific dishonesty, which confirmed the accusation and lack of expertise in relevant fields used in the book. The Danish Ministry of Science, Technology and Innovation criticised procedural aspects drawn by the DCSD, though decided not to reinvestigate. The Skeptical Environmentalist established Lomborg's profile as an opponent of the scientific consensus on climate change. In 2007, Lomborg published a follow-up work titled Cool It: The Skeptical Environmentalist's Guide to Global Warming.

== Background ==

The book was written by Bjørn Lomborg, a Danish statistician who worked at Aarhus University. The ideas and writing for the book began in the 1990s. He was inspired by an interview with Julian Lincoln Simon which was published in the magazine Wired, in which Simon claimed that calculations he had conducted with publicly available data led him to conclude that standard doomsday conceptions of the state of the world were incorrect. He assumed Simon's views were the product of his American conservative thinking, but in 1997, Lomborg undertook a similar assessment with some of his students and came to similar conclusions as Simon.
In 1998, Lomborg published four articles in the Danish newspaper, Politiken, outlining his research and study. These attracted media coverage and controversy in Denmark. These findings were published as a book in Danish on 22 September 1998 as Verdens Sande Tilstand (The True State of the World) by Centrum. and as The Skeptical Environmentalist in English, by Cambridge University Press in 2001. Sections on global warming, notes and references were expanded in the English edition.

== Contents ==
The Skeptical Environmentalist's subtitle refers to the State of the World report, published annually since 1984 by the Worldwatch Institute. Lomborg designated the report "one of the best-researched and academically most ambitious environmental policy publications," but criticized it for using short-term trends to predict disastrous consequences, in cases where long-term trends would not support the same conclusions.
In establishing its arguments, The Skeptical Environmentalist examined a wide range of issues in the general area of environmental studies, including environmental economics and science, and came to a set of conclusions and recommendations. Lomborg's work directly challenged what it framed as "the Litany of our ever deteriorating environment" by interpreting data from around 3,000 mostly secondary sources. The author suggests that environmentalists have diverted potentially beneficial resources to less deserving environmental issues in ways that were economically damaging. He portrays his book as an unbiased and scientific refutation of the claims of environmental groups. Much of the book's methodology and integrity have been subject to criticism, which argue that Lomborg distorted the fields of research he covers.
The Skeptical Environmentalist is arranged around four major themes:
