In December 2021, the Environmental Protection Agency (EPA) released new greenhouse gas emission standards for new passenger cars and light trucks. The final rule requires automakers to meet an industry-wide projection target of 161 grams of carbon per mile (g/mi) in 2026, increasing gravity by 9.8 percent of the 2022 to 2023 model years, 5.1 percent of the 2024 model year, 6.6 percent of the 2025 model year and 10.3 percent of the 2026 model year. In the NPRM, the agencies sought feedback on various possible changes to existing compliance flexibilities that have been created in recent years. The vast majority of existing compliance flexibilities will not be changed, but a small number of flexibilities related to real energy efficiency improvements are being finalised. In addition, EPA will continue to allow manufacturers to make improvements to refrigerants and air-conditioning leaks, and will attribute these improvements to CO2 compliance, and EPA will not make any changes to available credits. EPA also makes no changes to existing CH4 and N2-O standards. The EPA is also expanding the “0 g/mi upstream” incentive for electric vehicles beyond the current end of MY 2021 to MY 2026. The EPA also establishes a credit multiplier for natural gas vehicles through the 2026 model year. Otherwise, the compliance flexibility of the two programs for the final rule does not change significantly. These changes should help to streamline the use of these flexibilities by manufacturers in certain respects.
Although manufacturers and suppliers requested a number of other additional compliance flexibilities, the bodies concluded that the existing flexibilities mentioned above are appropriate and proportionate and that additional flexibilities are not justified. In many cases, vehicle technology is clearly evident from 2016 compliance data (e.g., compliance data clearly indicates which vehicles have turbochargers and which have continuously variable transmissions), but in some cases, technology levels are less observable. For the latter, as well as for the degree of mass reduction, the analysis categorized the technology already used in a particular vehicle. Similarly, the technical evaluation was used to determine whether higher levels of weight reduction can be used in a particular vehicle in a practical and safe manner. The following sections provide a brief technical overview of the CAFE model, including NHTSA`s changes to the model since 2012, before discussing the model`s inputs and then digging deeper into how the model works. For more information on the latter topic, see the July 2018 CAFE Model Documentation Draft, which is available in the list for this rule-making and on the NHTSA website. Vehicle owners also have to deal with fuel prices at the pump. The agencies noted in NPRM that with high fuel prices, the value of fuel saved could be sufficient to offset the cost of further improvements in fuel economy and emission reductions, but the agencies realized that current projections by the Energy Information Administration at the time did not indicate particularly high prices for the foreseeable future. The agencies explained that since the final settlement in 2012, fundamental structural changes have taken place in global oil markets, mainly due to increased U.S. shale oil production and exports.
The consequence of declining efficiencies over time due to stricter fuel economy and emission reduction standards, especially in combination with relatively low fuel prices, is a greater difficulty for car manufacturers to find a market of consumers willing to buy vehicles that meet increasingly stringent standards. U.S. consumers have long demonstrated that during periods of relatively low fuel prices, fuel economy is not a top priority for the majority of them, even when highly fuel-efficient vehicle models are available. The regime proposed today is expected to prevent more than 12,700 road fatalities [38] and significantly more injuries than the lifespan standards set out in the final 2012 regime, as more new and safer vehicles are purchased than current (and augural) standards. Much of this safety benefit will come from improved fleet throughput, as more consumers can afford newer, safer vehicles.

This effect is mathematical in nature and has been known for a long time, but combined with relatively low fuel prices, perhaps by 2050, and the likelihood that a large majority of U.S. consumers may therefore continue to place greater value on vehicle characteristics other than fuel economy, it complicates the ability of manufacturers to operate light-duty vehicles with ever higher fuel consumption and ever lower carbon dioxide emissions. sell. Simply put, if gasoline is cheap and any additional upgrades save less gas anyway, most consumers prefer to spend their money on attributes other than fuel economy when considering buying a new car, whether it`s more safety technology, a better infotainment package, a more powerful powertrain, or other features (or they even prefer spend the savings on something other than cars). Manufacturers trying to sell consumers more fuel economy in such circumstances may convince consumers who value efficiency and reduced carbon emissions, but consumers decide for themselves which features are worth to them. And while some argue that consumers do not sufficiently consider or evaluate future fuel savings in their vehicle purchasing decisions,[26] information on the benefits of higher fuel economy has never been more readily available than it is today, with a variety of online tools and mandatory disclosures prominently displayed on new vehicles on the Monroney label showing fuel savings. compared to medium vehicles. It`s not a question of “if you build it, they will come.” Despite the wide availability of fuel economy information, and the fact that manufacturers are building and marketing vehicles with higher fuel content and increasing their range of hybrid and electric vehicles, consumer preferences have shifted significantly from lower- and medium-sized passenger cars to crossovers and truck-based commercial vehicles in recent years. Because gasoline prices have remained low. [27] Some consumers clearly place more importance on fuel consumption and low CO2 emissions than on other features and, thanks to CAFE and CO2 standards, they have a choice between a wide choice of fuel-efficient and low-CO2 vehicles, but these consumers represent a relatively small percentage of buyers. The sections above explain what Congress deemed important enough to codify when it ordered each agency to regulate, and begin to explain how agencies have interpreted those instructions over time and in this final rule. The following section examines in more detail the interaction between congressional agency orientation and the aspects of the marketplace that these regulations affect, as follows.
