New Rules Includes Hybrids and PHEVs to Cut Tailpipe Emissions

New standards are coming for tailpipe emissions in the next few years. An announcement from the Biden administration this week unveiled the rules, which look to remove more than seven billion tons of carbon and other pollutants from our air.


Vehicle emissions account for 28 percent of the United State’s greenhouse gases, and the new standards are said to help reduce that number while saving nearly $100 billion in healthcare costs and billions more in fuel and other vehicle costs. The Biden administration has a goal of cutting emissions by 50 percent or more from 2005 levels by 2030.


The EPA proposed similar rules, but the Biden administration’s plan is slightly less ambitious after the United Auto Workers Union and automakers pushed back on the agency’s ideas. Biden’s plan rolls out between 2027 and 2029 before ramping up between 2030 and 2032. However, rather than relying solely on EVs to cut tailpipe emissions as initially suggested by the EPA, the new plan includes a range of electrified and even efficient gas engines to ease emissions.


It's not a mandate to force automakers to build EVs -- instead, the new rules will be stricter than at present. It will be up to automakers to figure out how to comply.


The UAW praised the announcement, saying “By taking seriously the concerns of workers and communities, the EPA has come a long way to create a more feasible emissions rule that protects workers building ICE vehicles, while providing a path forward for automakers to implement the full range of automotive technologies to reduce emissions.”


Industry leaders have opposed an EV-only path forward, citing wavering demand and high prices.

    "Vehicle emissions account for 28 percent of the United State’s greenhouse gases,"


    Not VEHICLE, Transportation emissions account for 28% of US greenhouse gases. Of that light duty vehicles account for roughly 60%. So we are really talking about 15%, not 28%.


    FYI that Electricity accounts for 25% of US greenhouse gases and Industry 23%. Electric cars are hardly gonna save the planet. we got plenty of other issues.

    “We’re not making gasoline cars illegal!”


    But at the end of the day you’ll have to buy electric

  • Zerofoo Some high school kid is going to love this car.
  • Tane94 Model names from the past are not the answer. Cadillac is still recovering from the New York Joe deNysche error. What is Cadillac's identity? It walked away from its Standard of Excellence image long ago. Is it Electric Luxury? European Luxury built here? luxury performance? I don't know. Is all-electric models by 2030 still the goal?
  • MaintenanceCosts (1) Crash program to redesign all of the interiors, now, to banish all evidence of cost-cutting and have at least as much flash as current Mercedes.(2) XT6 gets the 3.0T engine. Both XT6 and XT5 get an Acura-style AWD system that will make them stop feeling so much like front-drivers.(3) XT6, XT5, and CT5 all get a restyle along the lines of the '89 restyle of the DeVille and co. - that is, add length even with overhang if you have to, add swagger, add fancy.(4) New platform for large unibody SUVs, either electric or hybrid, to compete straight across with the top two Range Rover models. If they are going to be a real luxury brand they need SUVs more refined than the Escalade. Keep selling the Escalade alongside the new ones for the existing cigarette-boat audience.(5) XT4 and CT4 get put out of their misery, or maybe brought back as Buicks.
  • Jkross22 Cadillac - We took over the sport sedan market (what's left of it) from BMW. Oh and we also have this Escalade that everyone loves and this EV that looks like Peugeot designed it.
  • Kwik_Shift_Pro4X I would only buy with manual. Even if the auto is repaired, it will most likely fail again. Just a bad design.
