Background
Mission:The Yolo-Solano Air Quality Management District is responsible for protecting human health and property from the harmful effects of air pollution.

Air Pollutants of Concern
Ozone - susceptibility to
respiratory infections - increased risk of
heart attacks and strokes - increase in
mortality/premature deaths
- damage to crops and natural vegetation
Particulate Matter - increased irritation of
the airways, coughing or difficulty breathing
- aggravated asthma - irregular heartbeat - heart attacks - cancer risk (diesel
PM) 5
Both pollutants have potential for a variety of respiratory and cardiopulmonary impacts:
Air Pollutants of Concern
How Ozone is Formed
6
Sacramento Federal Nonattainment Area for 8 Hour Ozone Standard
7
EPA Classification : SevereAttainment Deadline: June 2019
Includes Sacramento and Yolo Counties, and portions of El Dorado, Placer,
Sutter and Solano Counties
Air Pollutants of Concern
Regional Inventory of Ozone Forming Emissions
8
Air Pollutants of Concern
Particulate Matter (PM 10, PM 2.5)
Major Sources:
Diesel Vehicle ExhaustFireplaces/Woodstoves
9
Air Pollutants of Concern
Carbon dioxide (CO2) emitted during the combustion of fossil fuels traps heat in the atmosphere and contributes to global warming.
10
Motor Vehicles and Air Quality
Motor vehicles have become significantly more energy efficient and less polluting, however population growth and increased driving has created the need to shift to cleaner technologies. 11
Motor Vehicles and Air Quality Autos and light/med
trucks account for over 45% of the ozone forming emissions and almost 40% of the GHG emissions in the Sacramento Region
12
Motor Vehicles and Air Quality
13
One strategy to help meet our air quality standards, greenhouse gas reduction goals and reduce petroleum dependence is to shift from gasoline vehicles to PEV’s.
Air Quality Benefits of PEV PEV vs. average new gasoline
vehicle driven 12,000 miles/year for 8 years:
- Annual reductions in ozone and particulate forming emissions: 14 pounds per year (112 pounds over
8 years) - Annual GHG reductions: 5.4 metric
tons of CO2 (43.2 metric tons over 8 years)
14
Gasoline Vehicle vs. PEV “Upstream” Emissions
Gasoline Vehicle Emissions Tailpipe emissions
Upstream/power plant Emissions associated with
getting gasoline to market:
- Importing of crude oil in tanker ships
- Refining of oil to gasoline- Trucks delivering gas to
fueling station
- Gas station operations/ pumping gasoline
into vehicle
Plug-in Vehicle Emissions
No tail-pipe emissions
Power plant emissions: PEV recharges directly from
electrical grid eliminating many steps and upstream emissions associated with gasoline production
15
Additional PEV Benefits
Reduced dependence on petroleum - Most electricity in CA produced from natural gas/hydro/wind/solar
No coolant or motor oil - less potential for water pollution
from spills and storm run-off Quiet operation
