(CfA), is a part-time employee of the Smithsonian Institution, a government agency covered by the Freedom of Information Act (FOIA). Greenpeace worker Kert Davies made a succession of FOIA requests for Soon's correspondence and grant arrangements and in 2014 was given documents disclosing arrangements both Soon and the CfA had with funders. Later in 2014, Davies left Greenpeace to become executive director of a newly founded non-profit, Climate Investigations Center. The Smithsonian does not fund Soon, who "pursues external grants to fund his research." This funding had exceeded US$1.5 million since 2001; under standard CfA procedures, more than half of the $1.2 million funding since 2005 had gone towards the Smithsonian's facility operating costs, with the remainder being passed on to Soon as his salary. Other researchers there have a similar arrangement, but nearly all of their funding comes through peer-reviewed award processes from government bodies such as NASA and the National Science Foundation, whereas Soon has received very little federal money. Soon's funding by private interests is highly unusual at the Smithsonian. It included at least $230,000 from the Charles G. Koch Foundation which is associated with the oil industry and $469,560 from the Southern Company which uses coal to generate electricity. Exxon Mobil and the American Petroleum Institute also provided funding, which was later replaced by anonymous donors through the Donors Trust, a donor-advised fund that offers anonymity to clients who do not wish to make their donations public. The latter was identified by a 2013 Drexel University study as the largest single provider of money to political efforts to fight climate-change policy. A 2008 contract agreed to by the CfA required the institute to notify the Southern Company before disclosing that Southern had provided funding, and both the CfA and Willie Soon to provide Southern with advance copies of any publications "for comment and input", though the company could not block publications or require changes. The Chinese Science Bulletin has a strict policy requiring disclosure of "all relationships or interests that could influence or bias the work", including "professional interests or personal beliefs that may influence your research", for example previous receipt of research grants. The Monckton et al. paper published in January 2015 included a statement by the authors, including Soon, that they had no conflict of interest, and Davies wrote to the journal about the undisclosed funding shown by the documents.
