An Energy Department climate office supervisor reportedly told staffers not to use the phrases "climate change," "emissions reduction" or "Paris agreement" in written memos, Politico reported.
Employees learned of the ban at a staff meeting Tuesday, the same day President Trump signed an executive order that rolled back many of former President Obama's climate and energy policies. Officials in the State Department and other Energy Department offices said they hadn't been given a list of banned words.
Senior officials told Politico using the banned phrases would spark a "visceral reaction" from Energy Secretary Rick Perry and White House advisers in the department. The DOE denied banning any words.
What exactly is this office to call itself now? The International C****** Office?
Other sources said there was no official ban, but the wording of some controversial topics had changed to avoid reactions.
But some activists, like Sierra Club climate policy director Liz Perera, blasted the alleged policy change.
On Tuesday, Trump rolled back the Obama-era Clean Power Plan, which set limits on carbon emissions. Climate activists heralded the move, but some argued it hindered American energy independence.
Trump also asked government agencies to identify rules that hindered domestic energy production and removed Obama's moratorium on coal. His aides called the move a job creator, but League of Conservation Voters Gene Karpinski said it was dangerous to Americans' health and safety.
