California's Air: Strategies For Pollution Reduction

California is one of the most polluted states in the US, with over 90% of its residents breathing unhealthy levels of one or more air pollutants. The state's unique environmental conditions, from its mountainous terrain to its warm climate, are perfect for forming and trapping air pollutants. While wildfires represent a temporary source of emissions, their impact on yearly averages can be severe. To combat this, the California Department of Forestry and Fire Prevention (CAL FIRE) is working to clear volatile forest undergrowth through prescribed fires. Additionally, individuals can play a role in reducing air pollution by adopting environmentally friendly practices, such as walking or biking instead of driving, reducing energy consumption, and choosing sustainable products.

Reduce car usage, opt for walking, biking, public transport, or carpooling

California is one of the most polluted states in the United States, with over 90% of its residents breathing in unhealthy levels of air pollutants. The state's geography, climate, and temperature inversions all contribute to trapping air pollutants. While cars provide an unparalleled level of mobility, they also have negative financial, public health, environmental, and social impacts.

To reduce car usage, Californians can opt for walking or biking when possible. This not only improves air quality by reducing vehicle emissions but also provides physical and mental health benefits. For longer distances, public transportation or carpooling are more environmentally friendly alternatives.

California is working towards reducing vehicle emissions and improving air quality. The state has established the Advanced Clean Cars II program, which aims for all new passenger vehicles sold to be zero-emission by 2035. Additionally, the Driving Clean Assistance Program (DCAP) provides incentives for low-income and disadvantaged communities to purchase clean air vehicles, including electric, hybrid, and fuel cell options.

Individuals can also contribute to reducing air pollution by organizing and condensing errands into one trip, telecommuting when possible, and driving less, especially on days with unhealthy air quality. These small changes can collectively make a significant impact on California's air quality and the health of its residents.

Choose energy-efficient, low-emission vehicles, e.g. electric cars

California is one of the most polluted states in the United States, with over 90% of Californians breathing unhealthy levels of air pollutants. A significant portion of this pollution comes from cars and trucks, with gasoline and diesel-powered motor vehicles being a major source. To combat this issue, individuals can choose to purchase energy-efficient, low-emission vehicles, such as electric cars.

Electric vehicles (EVs) have zero tailpipe emissions, which means they do not produce any direct emissions through their tailpipes like conventional vehicles with internal combustion engines. However, it is important to consider the emissions associated with electricity generation and EV battery manufacturing. The environmental impact of EVs depends on the energy sources used for electricity generation in a particular region. In areas with relatively low-polluting energy sources, such as wind or solar power, EVs have a significant life cycle emissions advantage over conventional gasoline or diesel vehicles. However, in regions with higher-emissions electricity sources, such as coal or natural gas, the life cycle emissions benefit of EVs may be less pronounced.

That being said, research has shown that even when accounting for electricity emissions, EVs are generally responsible for lower levels of greenhouse gas emissions (GHGs) compared to average new gasoline cars. This is because, over the lifetime of the vehicle, the total GHG emissions associated with EV manufacturing, charging, and usage are typically lower than those of a gasoline car. Additionally, as the energy grid transitions to more renewable energy sources, the total GHGs associated with EVs are expected to decrease further.

When considering purchasing an EV, individuals can use tools like the Beyond Tailpipe Emissions Calculator provided by the EPA and the Department of Energy to estimate the greenhouse gas emissions associated with a particular EV model in their zip code. This allows buyers to make informed decisions and compare the environmental impact of different vehicles.

By choosing energy-efficient, low-emission vehicles like EVs, Californians can play a crucial role in improving air quality and reducing their carbon footprint. This, combined with other sustainable practices, can help create a cleaner and healthier environment for all residents.

Reduce energy consumption at home and work, and choose sustainable products

California is one of the most polluted states in the United States, with around 90% of Californians breathing in unhealthy levels of one or more air pollutants. To tackle this, Governor Newsom has released a climate plan that includes a commitment to achieving carbon neutrality by 2045, reducing fossil fuel consumption by 86-94%, and creating 4 million new jobs.

At Home

• Insulate your home and water heater.
• Use energy-efficient appliances, light bulbs, and an EPA-approved wood-burning stove.
• Turn off appliances and lights when not in use.
• Wash laundry in cold water and line dry.
• Use reusable dishes, utensils, and fabric napkins instead of disposable ones.
• Use water-based cleaning products that are labelled 'zero VOC'.
• Store solvents in airtight containers.
• Use an electric or push lawnmower.
• Plant a tree.

At Work

• Telecommute if possible.
• Start a recycling program.
• Print and photocopy on both sides of the paper.
• Turn off office equipment after hours.

Sustainable Product Choices

• Buy local, organic, and sustainable food.
• Choose products made from recycled materials, bamboo, or hemp.
• Use durable, reusable grocery bags.

Support the Smog Check Program and reduce exposure to toxic chemicals

California is one of the most polluted states in the United States. A study from 2008 at California State University, Fullerton, CA, found that air pollution in California claims more lives than car accidents. The California Smog Check Program is a joint effort between the California Air Resources Board, the California Bureau of Automotive Repair, and the California Department of Motor Vehicles. The program requires vehicles manufactured in 1976 or later to participate in biennial smog checks in certain counties. The aim is to reduce air pollution from vehicles by ensuring that cars with excessive emissions are repaired according to federal and state guidelines.

The California Air Resources Board (CARB) identifies air pollutants as toxic air contaminants (TACs) and traditional pollutants. TACs may cause serious long-term effects such as cancer, even at low exposure levels. Traditional pollutants include ozone and particulate matter, which are formed when pollutants emitted by vehicles, industry, and consumer products react with each other on hot, sunny days.

To support the Smog Check Program and reduce exposure to toxic chemicals, Californians can take several actions. When buying a new car, individuals can opt for the most efficient, lowest-polluting vehicle, or even a zero-emission electric car. Electric cars are exempt from the Smog Check Program. Additionally, individuals can reduce their car usage by walking, biking, taking public transportation, or carpooling when possible.

Furthermore, energy consumption can be reduced by turning off lights when leaving a room and unneeded office equipment after hours, as well as by harnessing natural sunlight. Individuals can also choose sustainable products and eliminate their exposure to toxic chemicals at home. This includes using water-based cleaning products labelled "zero VOC" and opting for natural substitutes.

Plant trees and support initiatives for cleaner air

California is facing a serious air pollution problem, with a 2008 study from California State University, Fullerton CA, finding that air pollution in the state is claiming more lives than car accidents. The state's geography and climate are partly to blame, as they create conditions that trap air pollutants. To tackle this issue, individuals and organizations in California are taking action to promote cleaner air through various initiatives, including tree planting and supporting organizations like TreePeople and One Tree Planted.

TreePeople is an organization dedicated to creating a greener and more sustainable future in California. They focus on fire resilience, working to restore fire-scarred lands, prevent future wildfires, and protect biodiversity. They also advocate for, implement, and manage school greening projects to protect students from extreme heat, air pollution, and polluted water. TreePeople offers nature trails, education, and cultural programming at its 45-acre headquarters in the Santa Monica Mountains and stewards over 3,000 acres of land in the same mountain range.

One Tree Planted is another organization working to restore California's ecosystems by planting trees in areas affected by wildfires, increasing biodiversity, and protecting freshwater and soil. They also aim to boost the liveliness of California communities and support native biodiversity. One Tree Planted has undertaken reforestation projects to restore degraded forest lands, improve watershed and forest health, and implement safeguards to mitigate future climate change impacts.

In addition to supporting these organizations, individuals can take action to reduce air pollution in California. This includes simple steps such as walking, biking, or taking public transportation instead of driving, reducing energy consumption, choosing sustainable products, and eliminating exposure to toxic chemicals. Individuals can also support political action for cleaner air and take steps to reduce energy consumption and chemical usage in the workplace.

By planting trees and supporting initiatives for cleaner air, California can work towards improving its air quality and reducing the health risks associated with air pollution.
