It is the latest in a series of Trump administration efforts to dispute, silence or downplay climate change.

The Energy Department has added “climate change,” “green” and “decarbonization” to its growing “list of words to avoid” at its Office of Energy Efficiency and Renewable Energy, according to an email issued Friday and obtained by POLITICO.

The words on the DOE list are at the heart of EERE’s mission: It is the government’s largest investor in technologies that help reduce heat-trapping emissions that cause climate change as well as the hazardous pollution from fossil fuels. It is the latest in a series of Trump administration efforts to dispute, silence or downplay the realities of climate change.

“Please ensure that every member of your team is aware that this is the latest list of words to avoid — and continue to be conscientious about avoiding any terminology that you know to be misaligned with the Administration’s perspectives and priorities,” the directive from acting director of external affairs Rachel Overbey said.
