The terms staffers are forbidden from using include: climate change, green, decarbonization, energy transition, sustainability, sustainable, subsidies, tax breaks, tax credits, and carbon footprint.

Also on the banned word list is the term “emissions.” According to the report, the term apparently implies some level of negativity, despite the neutrally worded dictionary definition. The U.S. Supreme Court ruled in 2007 that greenhouse gases aren’t simply emissions, though, but instead can be regulated as air pollutants.
