California Supplemental (CSE) Practice Exam

Which agency is responsible for reducing emissions from mobile sources?

1. California Department of Fish and Wildlife

2. State Water Resources Control Board

3. Air Resources Board

4. County Flood Control District

The correct answer is: Air Resources Board

The agency responsible for reducing emissions from mobile sources is the Air Resources Board (ARB). This board plays a critical role in California's air quality management by setting the standards and regulations to oversee the emissions from vehicles, including cars, trucks, and buses. The ARB is tasked with enforcing vehicle emissions standards, developing strategies for reducing air pollution, and implementing programs aimed at improving air quality statewide. The emphasis on mobile sources is particularly significant in California due to its high traffic volumes and diverse vehicle fleet, which contribute to air pollution and public health issues. As the primary agency focused on air quality and greenhouse gas reductions, the ARB's initiatives include promoting cleaner fuels, setting stringent automobile emissions standards, and supporting the development of zero-emission vehicles, all of which contribute to reducing emissions from mobile sources effectively. The California Department of Fish and Wildlife, State Water Resources Control Board, and County Flood Control District focus on different environmental and resource management issues, such as wildlife conservation, water quality management, and flood risk, respectively, rather than on mobile source emissions.
