The Biden administration recently announced a very ambitious — to say the least — rule on tailpipe emissions. But while the rule’s legal and political standing might be a bit uncertain — it’s seen by many as a de facto ban on conventionally fueled cars and trucks and is likely to face several court challenges — doubts also remain about whether it matches up with the realities of today’s energy world. In today’s RBN blog, we look at the new rule, what it would mean for U.S. consumers and automakers, and how it conflicts with the views of RBN’s Refined Fuels Analytics (RFA) practice on the future of global oil and refined products demand and the rate of electric vehicle (EV) adoption.
