In December 2020, the EPA issued an Enforcement Alert regarding aftermarket defeat devices that “bypass or render inoperative required emissions control systems, resulting in significant increases in harmful air emissions” from motor vehicles and nonroad equipment.

The EPA’s Air Enforcement Division (AED) released a study revealing that as many as 500,000 diesel pickup trucks have had emissions controls removed within the last decade. Tampering with these emissions control devices is estimated to produce “more than 570,000 tons of excess oxides of nitrogen (NOx) and 5,000 tons of particulate matter (PM)” in […]
On September 23, 2020, California Governor Gavin Newsom signed an Executive Order mandating that all new passenger trucks and cars sold in the state be emissions-free by 2035. Symbolically, the order was signed on the hood of the Ford Mustang Mach-E, with electric vehicles (EVs) manufactured by Honda, Audi, and Tesla in the background.
On May 27, 2020, 23 attorneys general and a handful of city attorneys filed a lawsuit challenging the Trump administration’s Safer Affordable Fuel-Efficient Vehicles (SAFE) rules revising extant fuel efficiency and emissions standards for passenger vehicles. SAFE effectively undoes President Barack Obama’s 2010 Clean Car Standards (CCS), which set forth aggressive fuel economy and greenhouse […]
In June 2019, the EPA’s Office of Enforcement and Compliance Assurance announced its six National Compliance Initiatives (NCIs) for fiscal years 2020 through 2023. Before the Trump administration, the Agency referred to this program as its National Enforcement Initiatives. Regardless of the title, the program identifies sectors or types of activities that are in need […]
In the second step taken under the Cleaner Trucks Initiative (CTI) it announced in November 2018, the EPA has released an advance notice of proposed rulemaking (ANPR) to solicit public comment on the outlines of proposed emissions standards for highway heavy-duty engines, which the Agency says it plans to issue in early 2020.
Seventeen states, the District of Columbia, and seven of the nation’s top environmental groups petitioned the U.S. Court of Appeals for the D.C. Circuit to review the legality of the Trump EPA’s decision to withdraw the Obama EPA’s January 2017 determination that the Agency’s 2012 greenhouse gas (GHG) emissions standards for model year (MY) 2022–2025 […]
Following several stern tweets from President Donald Trump, the EPA and the U.S. Department of Transportation (DOT) have put the California Air Resources Board (CARB) on notice that the voluntary framework the state reached with four major automakers “appears to be inconsistent with federal law.” The EPA/DOT letter urged CARB to disassociate itself from the […]
With several minor exceptions, the EPA is proposing to grant each of the requests four small-volume manufacturers (SVM) made for alternative greenhouse gas (GHG) emissions standards for their light-duty vehicles.
In its 2018 Automotive Trends Report, the EPA states that estimated real-world CO2 emissions from model year (MY) 2017 light-duty vehicles were at a record low and fuel economy at a record high. The report covers vehicles manufactured in 2017, the most recent year for which the Agency has complete data. The report is based […]
