Less vehicle emissions
California has been at the forefront of environmental initiatives and has stringent Vehicle Emissions Inspection Laws in place to ensure cleaner air and reduce the impact of vehicle emissions on the environment. The state has implemented various measures to reduce vehicle emissions, such as the nation's first tailpipe emissions standards for hydrocarbons and carbon monoxide in 1966.
The California Air Resources Board (CARB), the state's environmental regulator, approved a rule that would require 100% of new light- and medium-duty vehicles sold in California to be zero-emission vehicles (ZEVs) by 2035. This rule is expected to have a significant impact on reducing vehicle emissions in the state. Additionally, California has mandatory emissions testing for various vehicle types, including biennial inspections for most vehicles, to control air pollution effectively.
The state also has specific programs targeting air quality, such as the Asthma-Friendly Outdoor (Ambient) Air Quality Flag Program, which aims to reduce exposure to outdoor environmental asthma triggers like ozone, particles, and pollens in Central California communities. California's efforts to reduce vehicle emissions have had positive outcomes, with one resident commenting that the air quality in LA is now much better than it was in the 1970s, when smog alerts were frequent.
California's leadership in vehicle emissions regulation has influenced other states to adopt similar standards. As of 2022, 17 states and the District of Columbia follow California's vehicle emissions rules, and states like New York, Massachusetts, Oregon, and Washington have expressed intent to follow California's ZEV mandate. However, some states, like Colorado and Pennsylvania, have stated they will not adopt California's standards.
California's efforts to reduce vehicle emissions are an important step towards improving air quality and public health. The state's regulatory actions, coupled with initiatives in other states, demonstrate a commitment to addressing the environmental and health impacts of vehicle emissions. While challenges and differing opinions remain, California's leadership in this area has the potential to drive significant progress in reducing vehicle emissions on a larger scale.

Improved ocean health
California's ocean health is affected by pollution from a variety of sources, including plastic waste, coal combustion, mercury, pesticides, herbicides, and fertilisers. These pollutants have detrimental effects on marine life, human health, and the state's economy, particularly in the tourism and fisheries sectors.
One of the most significant contributors to ocean pollution is plastic waste. Plastic products in the ocean can float or sink, remaining in the marine environment for decades. This poses a threat to marine animals, who can become entangled or ingest plastic, leading to digestive issues and even death. To combat this, individuals can refuse single-use plastics, opting for reusable alternatives such as grocery bags, bottles, and utensils. Additionally, supporting organisations like the Oceanic Society, Plastic Pollution Coalition, and Plastic Soup Foundation through donations or participation in their initiatives can help address plastic pollution.
Another critical aspect of improving ocean health is the reduction of chemical pollutants. Coal combustion, for instance, releases toxic coal dust into the air, endangering the health of nearby residents and contributing to ocean pollution. Similarly, mercury pollution has severe health implications, and eliminating its use can significantly reduce its presence in the ocean. Proper disposal of herbicides, pesticides, and cleaning products, as well as choosing non-toxic alternatives, can also lessen the chemical pollution that ends up in the ocean.
The implementation of sustainable practices can have a positive impact on ocean health. This includes reducing water usage to prevent excess runoff and wastewater from flowing into the ocean, choosing sustainable seafood to support responsible fisheries, and reducing plastic consumption and properly managing waste to decrease plastic pollution. Additionally, using fuel-efficient vehicles, carpooling, or opting for alternative modes of transportation like biking can help lower emissions and minimise the impact on the ocean.
By addressing plastic pollution, reducing chemical pollutants, and adopting sustainable practices, California can significantly improve its ocean health. These measures will not only benefit marine ecosystems and human well-being but also boost the state's economy and tourism industry, creating a healthier and more prosperous future for all.

Reduced wildfires
Wildfires have long been a threat to California, and they are expected to increase in frequency and intensity. They pose a severe threat to property and public safety, and they also have a detrimental impact on air quality. The smoke from wildfires contains toxic substances such as carbon monoxide, benzene (a carcinogen), and tiny particles of soot, which can enter airways and lodge in lungs, triggering asthma or heart attacks.
In 2020, California experienced its worst wildfires to date, with clusters of fires in Northern California surrounding the Bay Area and covering the skies with smoke. The smoke raised air pollutant concentrations to hazardous levels, with fine particulate matter (PM2.5) increasing significantly. The health impacts of these wildfires were comparable to the negative effects of ozone and PM2.5 air pollution, negating years of progress in air pollution control.
Additionally, wildfires emit enormous amounts of carbon and other greenhouse gases, contributing to climate change. This creates a vicious cycle, as climate change, in turn, worsens the frequency and intensity of wildfires. The fire season in California has already been starting earlier and ending later, and the severity of acreage burned has been increasing.
However, California has implemented strategies to mitigate the impact of wildfires on air quality. The state included the wildfire threat in its 2009 Climate Adaptation Strategy, aiming to reduce and adapt to the increasing future threat. California also conducted a vulnerability assessment to better understand the projected impact of environmental changes on wildfire activity.
Furthermore, California has introduced innovative vehicle emission control strategies, such as the nation's first tailpipe emissions standards for hydrocarbons and carbon monoxide in 1966. These regulations have successfully improved air quality in the state, demonstrating the government's commitment to balancing long-term health improvements with the economic costs of regulation.
Overall, while wildfires continue to pose a significant challenge to California, the state has taken proactive measures to reduce their impact on air quality and public health. Without the pollution caused by wildfires, California would experience improved air quality, reduced health risks associated with toxic smoke, and a decrease in the vicious cycle of climate change fueling more intense wildfires.
