The Department of Energy 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.
