1) Apr 17 -- Public Hearing for Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles-Phase 3

The Environmental Protection Agency (EPA) is announcing a two-day virtual public hearing to be held May 2 and May 3, 2023, on its proposal titled “Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles—Phase 3,” which was signed by Administrator Regan on April 11, 2023. An additional session may be held on May 4, 2023, if necessary to accommodate the number of testifiers that sign up to testify. In its proposal, EPA is proposing to promulgate new Greenhouse Gas (GHG) standards for heavy-duty highway vehicles starting in model year (MY) 2028 through MY 2032 and to revise certain GHG standards for MY 2027 that were established previously under EPA's Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles—Phase 2 rule. Finally, as part of this action, EPA is proposing to revise its regulations addressing preemption of state regulation of locomotives.

2) Apr 27 -- Proposed Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles—Phase 3
 
The Environmental Protection Agency (EPA) is proposing to promulgate new GHG standards for heavy-duty highway vehicles starting in model year (MY) 2028 through MY 2032 and to revise certain GHG standards for MY 2027 that were established previously under EPA’s Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles—Phase 2 rule (‘‘HD GHG Phase 2’’). This document proposes updates to discrete elements of the Averaging Banking and Trading program, including a proposal to eliminate the last MY year of the HD GHG Phase 2 advanced technology incentive program for certain types of electric highway heavy-duty vehicles. EPA is proposing to add warranty requirements for batteries and other components of zero-emission vehicles and to require customer-facing battery state-of-health monitors for plug-in hybrid and battery electric vehicles. In this document, we are also proposing additional revisions and clarifying and editorial amendments to certain highway heavy-duty vehicle provisions and certain test procedures for heavy- duty engines. Finally, as part of this action, EPA is proposing to revise its regulations addressing preemption of state regulation of new locomotives and new engines used in locomotives. Comments must be received on or before June 16, 2023.

3) Apr 12 [press release] -- Building on rapid advancements and investments in clean vehicle manufacturing, including investments in domestic manufacturing in the Inflation Reduction Act, EPA’s proposed standards would deliver on President Biden’s agenda to tackle the climate crisis

Today, the U.S. Environmental Protection Agency (EPA) announced new proposed federal vehicle emissions standards that will accelerate the ongoing transition to a clean vehicles future and tackle the climate crisis. The proposed standards would improve air quality for communities across the nation, especially communities that have borne the burden of polluted air. Together, these proposals would avoid nearly 10 billion tons of CO2 emissions, equivalent to more than twice the total U.S. CO2 emissions in 2022, while saving thousands of dollars over the lives of the vehicles meeting these new standards and reduce America’s reliance on approximately 20 billion barrels of oil imports. . . .

Since President Biden took office, the number of EV sales has tripled while the number of available models has doubled. There are over 130,000 public chargers across the country – a 40% increase over 2020. The private sector has also committed more than $120 billion in domestic EV and battery investments since President Biden signed the Inflation Reduction Act into law. The new standards proposed today reflect the advancements and investments in clean vehicle manufacturing, which have been accelerated by President Biden’s Investing in America agenda and complement the ongoing transition in the market towards cleaner vehicles.

The new proposed emissions standards for light-, medium-, and heavy-duty vehicles for model year (MY) 2027 and beyond would significantly reduce climate and other harmful air pollution, unlocking significant benefits for public health, especially in communities that have borne the greatest burden of poor air quality. At the same time, the proposed standards would lower maintenance costs and deliver significant fuel savings for drivers and truck operators.

-- Through 2055, EPA projects that the proposed standards would avoid nearly 10 billion tons of CO2 emissions (equivalent to more than twice the total U.S. CO2 emissions in 2022).  The proposed standards would reduce other harmful air pollution and lead to fewer premature deaths and serious health effects such as hospital admissions due to respiratory and cardiovascular illnesses.
-- By accelerating adoption of technologies that reduce fuel and maintenance costs alongside pollution, the proposed standards would save the average consumer $12,000 over the lifetime of a light-duty vehicle, as compared to a vehicle that was not subject to the new standards.
-- Together, the proposals would reduce oil imports by approximately 20 billion barrels.
-- Overall, EPA estimates that the benefits of the proposed standards would exceed costs by at least $1 trillion.

The first set of proposed standards announced today, the “Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium Duty Vehicles,” builds on EPA’s existing emissions standards for passenger cars and light trucks for MYs 2023 through 2026. . . .

The second set of proposed standards announced today, the “Greenhouse Gas Standards for Heavy-Duty Vehicles - Phase 3,” would apply to heavy-duty vocational vehicles (such as delivery trucks, refuse haulers or dump trucks, public utility trucks, transit, shuttle, school buses) and trucks typically used to haul freight. These standards would complement the criteria pollutant standards for MY 2027 and beyond heavy-duty vehicles that EPA finalized in December 2022 and represent the third phase of EPA’s Clean Trucks Plan.

These “Phase 3” greenhouse gas standards maintain the flexible structure that EPA previously designed through a robust stakeholder engagement process to reflect the diverse nature of the heavy-duty industry. Like the light- and medium-duty proposal, the heavy-duty proposal uses performance-based standards that enable manufacturers to achieve compliance efficiently based on the composition of their fleets.   

The projected net benefits of the heavy-duty proposal range from $180 billion to $320 billion. The proposal is projected to avoid 1.8 billion tons of CO2 through 2055, equivalent to eliminating all greenhouse gas emissions from the entire current U.S. transportation sector for an entire year, and deliver additional health benefits by reducing other pollutants from these vehicles. The standards would result in improved air quality nationwide, and those who live near major roadways and are disproportionately exposed to vehicle pollution and heavy-duty activity, which often includes low-income populations and communities of color, would benefit most directly.

The proposed standards align with commitments made by automakers and U.S. states as they plan to accelerate clean vehicle technologies in the light- and medium-duty fleets in the next 10 to 15 years. Car and truck companies are moving to include electric vehicles as an integral and growing part of current and future product lines, leading to an increasing diversity of clean vehicles for consumers.

These developments are bolstered by President Biden’s investments in America, which provide unprecedented resources to support the development and market for clean vehicle technologies and associated infrastructure and represent significant investment in expanding the manufacture, sale, and use of zero-emission vehicles. As these technologies advance, battery costs continue to decline and consumer interest in electric vehicles continues to grow. President Biden’s legislative accomplishments are also supporting critical generation of clean electricity and production of clean hydrogen needed to decarbonize transportation. EPA considered this rapid innovation in its assessment that tighter emissions standards are feasible.

EPA’s proposals are informed by robust and inclusive stakeholder engagement with industry, labor, advocates, and community leaders. EPA’s proposals will be published in the Federal Register and available for public review and comment, and the agency will continue to engage with the public and all interested stakeholders as part of the regulatory development process.
