The light-duty vehicle performance standard is proposed to be 82 gCO2/mile limit in 2032. The light-duty proposal includes a main proposal and three alternative options: a more-stringent option (Alternative 1), a less-stringent option (Alternative 2), and a third option that would begin more...
The U.S. Environmental Protection Agency has issued a much-anticipated proposed rule for more stringent emissions standards from heavy-duty vehicles and engines starting in model year 2027. The proposed emissions standards would reduce emissions of smog- and soot-forming nitrogen oxides (NOx) from h...
The new rules for heavy trucks and buses come a week after the EPAannounced new automobile emissions standardsfor passenger vehicles. Those rules relax initial tailpipe limits proposed last year but get close to the same strict standards set out by the EPA for model year 2032. The auto industr...
Supreme Court will take up a challenge related to California's tough vehicle emissions standards The new rules for heavy trucks and buses come a week after the EPA announcednew automobile emissions standards for passenger vehicles. Those rules relax initial tailpipe limits proposed last yea...
Wednesday's announcement is not the most ambitious version of these standards proposed by the EPA in April 2023, but allows for a slower ramp up to compliance for auto manufacturers. "Administrator Regan, Ali [Zaidi] – how do I say this? I know I've been a thorn in your side this ...
[3]continues to avoid an explicit EV mandate. Structurally, EPA’s approach employs the same framework currently used for U.S. GHG standards (i.e., a fleet average with “footprints” assigned to specific vehicle models).In the Proposed Rule, EPA set fo...
On the same day, the EPA proposed standards for light- and medium-duty vehicles. These proposals leverage advances in clean vehicle technology to further reduce climate pollution and smog- and soot-forming emissions, according to the EPA. For additional insight, the light- and medium-duty pro...
standards are achievable and affordable. EPA’s final standards for 2025 and 2026 deliver even greater net benefits and emissions reductions than those proposed in the initial rulemaking stage in August of 2021. Through 2050, the program will result in avoiding more than 3 B tons of GHG ...
“one potential pathway” for industry to meet the proposed standards by model year 2032, at which point ZEVs would make up 50% of vocational vehicles, 34% of day cab tractors, and 25% of sleeper cab tractors. The first two targets would include the use of both battery electrical and ...
EPA Administrator Stephen Johnson says by 2030 the proposed Mobile Source Air Toxic regulations, together with fuel and vehicle standards already in effect, would reduce toxic emissions from passenger vehicles to 80 percent below 1999 levels.
