Air Quality Planning and Science Division

Current Activities

SB 1 Report - Among other provisions, SB 1 states that as of January 1, 2020, the California Department of Motor Vehicles (DMV) must check that vehicles are compliant with, or exempt from, CARB’s Truck and Bus Regulation prior to being registered to operate in California
Port Congestion - Ports in California experienced a substantial increase in cargo imports, resulting in significant congestion at terminals and in surrounding areas. This has led to emissions increases from freight-related sources which can negatively impact air quality especially in communities near ports. The following documents detail the emission impacts from freight related sources due to this congestion.
SMOG check Certification - California Air Resources Board (CARB or Board) staff prepared the California Smog Check Performance Standard Modeling (PSM) and Program Certification for the 70 parts per billion (ppb) 8-hour Ozone Standard (referred as “Smog Check Certification”) to address State Implementation Plan (SIP) requirements of the federal Clean Air Act (CAA, or the Act) for ozone nonattainment areas within the State.
Emissions Surveillance Testing
Mobile Source Strategy - The State of California has many air quality, climate, and community risk reduction goals to achieve over the next thirty years. CARB staff is developing the 2020 Mobile Source Strategy to take an integrated planning approach to identify the level of transition to cleaner mobile source technologies needed to achieve all of California’s targets. Mobile sources and the fossil fuels that power them continue to contribute a majority of emissions of diesel particulate matter as well as smog.

Off-Road Advanced Clean Equipment - Off-road equipment (ORE) sector includes a broad spectrum of equipment and vehicle types, such as construction, agricultural, industrial, cargo handling equipment, locomotive, marine vessels, etc. Each ORE sector has unique operational characteristics and mechanical features.

ORE manufacturers have put a significant effort into implementing various zero-emission technologies into their conventionally fueled equipment. Many demonstration projects are going on are increasingly commercially available. This web page presents the zero-emission off-road equipment cases (known to CARB) currently available in the market or under R&D or demonstration stages. CARB staff aims to achieve the following goals by sharing the list.
