Increased use of lower-carbon liquid fuels in light-duty vehicles would lead to larger and faster reductions in greenhouse gas (GHG)&nbsp;emissions than EPA’s recently finalized EV-forcing tailpipe emissions standards, according to<a href="https://d35t1syewk4d42.cloudfront.net/file/2819">&nbsp;a new study</a>&nbsp;commissioned by the RFA and executed by an independent not-for-profit research institute.“Lowering the carbon intensity of liquid fuels can reduce CO2&nbsp;emissions faster than [electric]&nbsp;vehicles can displace the existing fleet,” according to the study. With a modest fuel carbon intensity reduction of just 1.25 percent per year nationwide, “the cumulative CO2&nbsp;benefit from 2027 to 2032 would be 77 percent larger than required by the EPA standards.” The study notes that “this CO2&nbsp;benefit could be achieved with a dramatically smaller on-road BEV fleet” than is anticipated by EPA under the new tailpipe standards.The study also found that if automakers rely primarily on BEVs to meet EPA’s tailpipe standards and if 17 states adopt California’s “zero emissions vehicle” mandate, U.S. liquid fuel consumption in 2035 will fall 38 billion gallons (compared to 2022 levels)&nbsp;and electricity consumption will jump 480 terawatt hours (roughly twice as much electricity as California uses annually).“Not only are EPA’s tailpipe standards based on the false premise that battery electric vehicles somehow have zero GHG emissions impacts, but the agency also failed to consider alternative solutions—like lower carbon liquid fuels—that could achieve the same goals more quickly and cost-effectively,” said RFA President and CEO Geoff Cooper. “This study shows that a nationwide move to reduce carbon intensity by just 1.25 percent per year would almost double the carbon savings expected by EPA under the tailpipe regulation, while allowing more light-duty vehicle and fuel options for consumers. The study also provides startling projections of the liquid fuel demand destruction and surge in electricity consumption that could result from EPA and California vehicle standards.”<a href="https://d35t1syewk4d42.cloudfront.net/file/2818">A second study</a>&nbsp;by the research institute shows that if the existing fleet of flex fuel vehicles (FFVs)&nbsp;used modestly larger amounts of E85, substantial GHG emissions reductions could be achieved. And, if those FFVs used&nbsp;only&nbsp;E85, GHG emissions would be reduced by up to 54 million metric tons per year—equivalent to almost 40 percent of EPA’s estimated GHG savings in 2035 from the new tailpipe standards.“Widespread use of E85 would have significant greenhouse gas emissions benefits,” the study concluded. According to the study, rapid growth in E85 “could achieve a large fraction” of the expected benefit from EPA’s tailpipe regulation “because E85 would improve life cycle CO2&nbsp;emissions for a large fleet of existing vehicles, not just new vehicles.”The study notes that using E85 in FFVs, which account for more than 8 percent of today’s on-road fleet, also would save consumers money at the pump. “In addition to the greenhouse gas benefits, E85 generally offers a retail price advantage,” the study found. “If all FFVs nationwide consumed only E85, it would result in annual savings of over $2.2 billion,” even when prices are adjusted to reflect E85’s lower energy density.&nbsp;“This study indicates that in the headlong rush to EVs, federal and state policymakers are overlooking an incredibly effective tool for reducing GHG emissions from the existing fleet,” Cooper said. “Nearly 21 million FFVs are already on the road today and they could produce enormous GHG emissions benefits if government leaders would simply put more emphasis and encouragement behind the use of low-carbon fuel blends like E85.”Cooper said the results of the study underscore another important error in EPA’s tailpipe regulation. “Automakers are strongly compelled to build more BEVs because EPA’s regulation assumes they have zero emissions,” Cooper said. “Yet, at the same time, EPA’s regulation discourages automakers from building new E85-capable FFVs because those vehicles are assumed to offer no benefit over gasoline vehicles, even though this study—and lots of other research—shows E85 provides at least a 35 percent GHG savings.”&nbsp;
