Key fossil fuel industry groups that FleishmanHillard has worked with include the American Petroleum Institute (API) in the United States and the Friends of Science (FoS) in Canada. It has also worked with major oil companies, including ConocoPhillips for work relating to climate change, as well as the National Association of Manufacturers (NAM).3Brulle, R.J., Werthman, C. “The role of public relations firms in climate change politics,” Climatic Change 169, 8 (2021) [Supplementary Materials].

FleishmanHillard ran a 2006 campaign opposing the Kyoto Protocol and featured interviews by climate change deniers including Tim Ball. The campaign resulted in a complaint against Friends of Science for purchasing radio ads in five key Ontario markets without registering with Elections Canada as a third party.4Mike De Souza. “Anti-Kyoto campaigner volunteer member of Tory election team,” Canwest News Service via Canada.com, February 21, 2008.

Stance on Climate Change


In 2018, the Climate Investigations Center (CIC) reached out to FleishmanHillard with a climate survey. Its response was to defer to its parent company, Omnicom, and its 2017 Corporate Responsibility Report.5FleishmanHillard PR,Climate Investigations Center. Accessed February 2023.

“The Omnicom report does not detail any of their policies on whether they accept clients with anti-environmental agendas or clients that promote climate change denial,” CIC reported.

When Omnicom responded to CIC’s email, it offered the following response:

“No, Omnicom does not have a formal position paper on climate change. The company regards the threat of climate change serious [sic] and we are taking measure [sic] to cut our carbon emissions around the world. For more information, you can check our annual CSR Report here – http://csr.omnicomgroup.com.”6“FleishmanHillard PR,” Climate Investigations Center. Accessed February 2023.


While Morten Paulsen and Byron Thomas were listed as communication contacts and lobbyists for FoS, FoS ran several radio ads, including one with the following transcript: 7Global Warming Myths Ad, January 2006.” friendsofscience.org.

“Here’s an easy true and false quiz. Ready?

  1. Global warming has caused more violent weather worldwide.
  2. The earth is warmer today than in the last thousand years.
  3. Carbon dioxide is dangerous pollution.
    If you said yes, you’ve been misled. Get the real answers at friendsofscience.org then ask your MPs why they want to spend billions on global warming theories.”
