Guus Berkhout

Berkhout founded the Netherlands-based organization Climate Intelligence Foundation (CLINTEL). Mid 2019 plans of CLINTEL and Berkhout were leaked showing that they were organizing a campaign against political commitments to net zero carbon emissions being made into law. The campaign features a number of academics and industry figures with ties to climate change sceptics groups, as well as members from oil and gas companies. Berkhout claimed the ideal of the organization was to provide an alternative to the Intergovernmental Panel on Climate Change.

In late September 2019 the group produced an open letter which presented a European Climate Declaration, stating that there was no climate emergency and repeating a number of claims that were inconsistent with the scientific evidence on climate. A fact check performed by climate scientists for Climate Feedback gave the letter an overall scientific credibility of "very low", and tagged it as "Biased, Cherry-picking, Inaccurate, Misleading". The analysis also added that, out of the roughly 500 signatories, only 10 self-identified as climate scientists. The document was later rebranded as the World Climate Declaration.

In 2008 he was made an Officer in the Order of Orange-Nassau.

For the 2006 Dutch general elections Berkhout had planned to form a new party with several scientists and entrepreneurs, but did not enter the elections, seeing the huge increase in new parties contesting the election.

Berkhout was chair of the independent Commission Experts Airplane sound from mid 2000 to December 2002. On request of the House of Representatives the Dutch Minister for Transport and Water Management, Tineke Netelenbos, instigated the commission. The commission was to look into the sound norms for Amsterdam Airport Schiphol for the upcoming five years. Berkhout resigned as chair after having the feeling that the independence of the commission was hindered by the Ministry, and having to wait for approval of a measurement plan for over half a year. The whole commission resigned, citing they had been actively worked against by the Ministry.

Berkhout was elected a member of the Royal Netherlands Academy of Arts and Sciences in 1990.

Berkhout started his career working for Shell. Between 1976 and 2007, he served as professor of acoustics, geophysics and innovation management, at Delft University of Technology. From 2000 to 2002 he was chair of a commission dealing with projected sound norms at Amsterdam Airport Schiphol, from which he resigned after feeling the commission's independence was undermined by the Ministry for Transport and Water Management. In 2019, Berkhout co-founded the climate sceptic organization Climate Intelligence Foundation (CLINTEL).

In 1964 Berkhout started working for Royal Dutch Shell. In 1976 he returned to Delft University of Technology, and became a professor of acoustic imaging and sound control. In 1987 he also became professor of geophysics. In 1998 he joined the board of the university, he stepped down in 2001, before the end of his term, due to differences with other board members in vision on the future of the university. In 2001 he became professor of innovation management and he retired from the university in 2007. Berkhout has pleaded against the increase of bureaucratic processes at universities.

Berkhout was born in 1940 in Den Helder. He studied electrical engineering at Delft University of Technology and obtained his degree in 1963. In 1970 he obtained a PhD cum laude in physics from the same university.
