It institutes a concept called “carbon-fee-and-dividend”, which is not really a “new” idea but which is still a pretty obscure one. It shouldn’t be. Anybody worried about climate change should familiarize themselves with the idea, which might be the single most powerful policy tool we can create to decarbonize our energy systems.
