Low-Emission Vehicle (LEV III) Program
In 2012, CARB adopted the Low-Emission Vehicle (LEV) III regulations as part of the Advanced Clean Cars rulemaking package that also includes the state’s zero-emission vehicle (ZEV) regulation. The LEV III regulations include increasingly stringent emission standards for both criteria pollutants and greenhouse gases for new passenger vehicles through the 2025 model year.
July 2011 commitment letters to the U.S. Environmental Protection Agency and Department of Transportation from the California Air Resources Board and major automakers documenting their support for a continued national program of light-duty GHG and fuel economy standards for MY 2017-2025.
Formal regulatory documents from the January 26, 2012, and March 22, 2012 hearings, such as the hearing notices, staff report and proposed regulatory documents for the LEV III regulation.
Formal regulatory documents for the rulemaking to consider proposed amendments to the new passenger motor vehicle greenhouse gas emissions standards for model years 2017-2025 to permit compliance based on federal greenhouse gas emission standards and additional minor revisions to the LEV III and ZEV regulations.
Formal regulatory documents for the rulemaking to consider proposed amendments to the LEV III criterial pollutant requirements for light- and medium-duty vehicles, the hybrid-electric vehicle test procedures, and the heavy-duty otto-cycle and heavy-duty diesel test procedures.
Formal regulatory documents for the rulemaking to consider proposed amendments to the Low-Emission Vehicle III Greenhouse Gas Emission regulation. These amendments will rescind the "deemed to comply" option if U.S. EPA relaxes the federal passenger vehicle greenhouse gas emission standards.
Informal regulatory documents for the development of the LEV III regulations.
