The UC Berkeley campus air quality is similar to that of its neighbouring cities
The air quality around the UC Berkeley campus is similar to that of its neighbouring cities. Berkeley's air quality index (AQI) in 2019 was 30, the same as San Francisco's and slightly higher than Oakland's AQI of 29 and Richmond's AQI of 27. All cities in the Bay Area had annual AQI levels below 50, indicating healthy overall air quality. However, it's important to note that yearly averages can underestimate health risks by smoothing over daily pollution spikes.
The Bay Area Air Quality Management District (BAAQMD) issues Spare the Air alerts when air pollution is forecast to exceed a US AQI of 100, becoming unhealthy for sensitive groups. These alerts advise residents to take action to protect their health and reduce emissions. PM2.5 advisories are common in the later summer, fall, and winter due to wildfires and wood-burning, while ozone advisories are more frequent in the summer with higher temperatures.
UC Berkeley's campus buildings vary in design, age, equipment, and human factors, all of which impact indoor air quality. During wildfire events, indoor air may smell smoky, but it typically contains lower particulate matter than outdoor air. Most buildings on campus have MERV-rated filters that reduce harmful particulate pollution.
Wood-burning contributes significantly to winter particulate pollution in the Bay Area, with an estimated 1.4 million fireplaces and wood stoves in use. The BAAQMD offers tips to reduce wood smoke pollution, such as switching to clean-burning natural gas devices or EPA-certified wood-burning devices, insulating homes, and reducing energy consumption.
Overall, while the UC Berkeley campus air quality is comparable to its neighbouring cities, it is important to stay informed about real-time air quality data and take necessary precautions to protect health and improve indoor and outdoor air quality.

The Bay Area Air Quality Management District issues alerts when residents should take action to protect their health
The Bay Area Air Quality Management District (BAAQMD) is responsible for issuing Spare the Air alerts to residents when air pollution is forecast to exceed a US Air Quality Index (AQI) of 100, which is considered "unhealthy for sensitive groups." These alerts are issued to encourage residents to take action and protect their health by reducing their personal emissions. The BAAQMD also provides guidelines and tips to help residents reduce their exposure to air pollution and improve indoor air quality during smoky conditions.
The Spare the Air alerts are typically issued for short-term PM2.5 or ozone pollution. PM2.5 advisories are more common in the later summer, fall, and winter months due to active wildfires and winter wood-burning practices. Ozone advisories, on the other hand, are more frequently reported in the summer when temperatures exceed 84 degrees Fahrenheit, creating ideal conditions for ozone formation.
The UC Berkeley campus is located on the east shore of the San Francisco Bay and experiences similar air quality to its neighbouring cities. While Berkeley's annual AQI meets the US Environmental Protection Agency (EPA) standard for "good," there are still health risks associated with daily pollution spikes. Alameda County, which includes Berkeley, received a failing grade for both short-term PM2.5 and ozone pollution in the 2020 "State of the Air" report by the American Lung Association.
To address air quality concerns and protect the health of residents, the BAAQMD takes several proactive measures. They provide a map of toxic emission data from permitted facilities in the Bay Area, helping residents understand potential pollution sources. Additionally, they work to reduce vehicle emissions by offering the Vehicle Buy Back Program, which removes older, high-polluting vehicles from the roads. The BAAQMD also encourages the use of electric heat pumps instead of wood-burning devices and provides tips for reducing wood smoke pollution, such as giving your fireplace or wood stove a break or switching to cleaner alternatives.

Wildfire smoke is a concern, with sensors installed at five major campus buildings to monitor air quality
The air quality in Berkeley is generally considered healthy, with the city's annual air quality index (AQI) score meeting the US Environmental Protection Agency (EPA) standard for "good". However, there are occasional spikes in pollution, particularly due to wildfires and wood-burning in the winter.
Wildfire smoke is a significant concern for the area, and UC Berkeley has taken steps to address this issue by installing sensors at five major campus buildings to monitor air quality. These buildings include the Valley Life Sciences Building, Stanley Hall, University Hall, Lawrence Hall of Sciences, and Crossroads Dining Common. The sensors provide real-time data on air pollution, allowing the campus to take necessary actions to protect the health and safety of its students, staff, and faculty.
The sensors are part of a larger network of air quality monitoring stations in the Bay Area, including Berkeley Aquatic Park, Laney College in Oakland, and the West Oakland monitor on West Grand Avenue. These stations help to track air pollution levels and issue alerts when the air quality is forecast to be unhealthy, especially for sensitive groups. During these times, residents are advised to minimise outdoor activity and take precautions to reduce their exposure to harmful pollutants.
UC Berkeley's efforts to monitor and address air quality issues, particularly wildfire smoke, demonstrate the university's commitment to ensuring a safe and healthy environment for its community. By providing real-time data and taking proactive measures, the university helps to mitigate the potential health risks associated with poor air quality due to wildfires and other sources of pollution.
In addition to the sensors, UC Berkeley has implemented other measures to reduce the impact of wildfire smoke on its campus. The university offers N95 respirators to employees when the AQI exceeds 150 due to wildfire smoke, and has posted a list of cleaner air facilities and buildings with mechanical ventilation filtration systems. These systems not only help reduce smoke indoors but are also effective at capturing the SARS-CoV-2 virus, providing an additional layer of protection during the COVID-19 pandemic.

Wood-burning devices are a significant source of particulate pollution on winter nights
Berkeley's air quality index (AQI) meets the US Environmental Protection Agency (EPA) standard for "good", indicating that the air is, on average, healthy to breathe. However, yearly averages tend to underestimate health risks, as they smooth over daily pollution spikes. For example, in 2020, Alameda County, of which Berkeley is a part, was graded an "F" for both short-term PM2.5 and short-term ozone pollution.
The Bay Area Air Quality Management District (BAAQMD) issues Spare the Air alerts when air pollution is forecast to exceed a US AQI of 100, becoming "unhealthy for sensitive groups". These alerts are most often issued for short-term PM2.5 or ozone pollution. PM2.5 advisories are often reported in the later summer, fall, and winter as a result of active wildfires and winter wood burning.
To address this issue, the BAAQMD has passed a regulation making it illegal to operate any wood-burning devices on Winter Spare the Air Days, which run from November to February. Additionally, they provide 10 tips to reduce wood smoke pollution, including giving your fireplace or wood stove the night off, replacing it with a clean-burning natural gas device, insulating your house, and switching to an EPA-certified wood-burning device or pellet stove, which emits up to 70% less PM.
