The House Natural Resource Committee's oversight panel, led by U.S. Representative Katie Porter of California, had invited leading advertising and public relations firms to share documents and information related to their work for oil, gas and coal companies and to testify at the hearing.
"Of note, PR (public relations) firms Singer Associates, Story Partners, and Pac/West Communications were invited but refused to attend," Committee spokesperson Lindsay Gressard said on Tuesday.
Gressard said FTI Consulting , another PR firm the committee is investigating, will not testify because it is working with the committee to turn in documents that the panel requested earlier this summer.
The hearing is the latest in a series of congressional hearings into whether the oil industry hindered government action on global warming.
While public scrutiny around energy companies' "greenwashing" claims has grown, the marketing agencies behind the campaigns have largely escaped scrutiny.
At the hearing, the committee will share findings of its investigation into public relations and advertising firms' work for fossil fuel companies based on its review of documents, such as their submissions for industry awards.
Republicans on the panel have criticized the hearing and said that advertising and public relations are out of the natural resource committee's jurisdiction.
The committee confirmed that witnesses will include Christine Arena, a former Edelman public relations executive who now works in social impact filmmaking; Anne Lee Foster, a Colorado-based anti fracking activist; Melissa Aronczyk, a communications professor and pro-fracking advocate Amy Cooke, head of Colorado's free market Energy and Environmental Policy Center for the Independence Institute.
