Reduce energy consumption
Energy consumption is a major contributor to air pollution, so reducing energy intake is an important step towards improving air quality.
One way to reduce energy consumption is to limit car usage. In California, about half of the air pollution comes from cars and trucks. Opting to walk, cycle, or take public transport can help reduce air pollution. When driving is necessary, it is important to maintain your vehicle, keep tires properly inflated, and remove unnecessary items to reduce the vehicle's weight. Additionally, when buying a new car, choose the most efficient, lowest-polluting vehicle, or even a zero-emission electric car.
Another way to reduce energy consumption is to make energy-efficient choices at home. This includes choosing efficient appliances and heating systems, such as those with the Energy Star label. It is also important to turn off electrical appliances and lights when not in use and to unplug multiple appliances from the wall by using a surge protector. Improving home insulation and ventilation can also help reduce energy loss and the need for additional heating or cooling.
On a larger scale, improving energy efficiency in industrial sites and buildings can significantly reduce air pollution. This can be achieved through mandatory building standards and retrofits that reduce energy consumption within buildings and industrial facilities. For example, China's mandatory energy-saving programs and building retrofits have led to significant reductions in air pollution and CO2 emissions.
Finally, transitioning to clean household energy and fuels is essential. This includes adopting solar stoves, solar panels, and low-emission biomass stoves. Behavior changes, such as cooking outside or opening windows while cooking, can also help reduce exposure to household air pollutants.

Improve industrial processes
Industrial processes are a major source of air pollution, and improving them can have a significant impact on air quality. Here are some ways to achieve that:
Implement Clean Technologies
Industries can adopt clean technologies to reduce emissions from industrial smokestacks. This includes deploying pollution-controlling technologies, such as the EPA's Diesel Emissions Reduction Program (DERA), which aims to reduce diesel exhaust emissions from fleets of vehicles, vessels, and equipment.
Improve Waste Management
Better management of urban and agricultural waste can help reduce air pollution. Capturing methane gas emitted from waste sites and using it as biogas instead of incinerating it is one such method. This not only reduces emissions but also provides an alternative energy source.
Reduce Toxic Emissions from Industrial Sources
The EPA has been working to reduce toxic air pollutants from large industrial facilities, known as "major sources," through the Clean Air Act. This includes setting standards for controlling emissions of air toxics from specific industries, such as chemical plants, oil refineries, aerospace manufacturers, and steel mills.
Address Indoor Air Pollution
Voluntary programs have been established to address indoor air pollution, which is a significant concern for people working in industrial settings. These programs aim to reduce exposure to hazardous pollutants and improve overall air quality in enclosed spaces.
Support Cleaner Industry and Energy Sources
Transitioning to cleaner industry practices and energy sources can significantly reduce air pollution. This includes adopting renewable and lower-emission power sources, such as solar, wind, or natural gas, and improving the energy efficiency of industrial processes.
By focusing on these strategies, we can work towards improving industrial processes and reducing their impact on air pollution, ultimately contributing to a healthier environment and improved public health.

Change transport methods
Transport is a major contributor to air pollution, with cars and trucks accounting for about half of the air pollution in California. Therefore, changing the way we travel can have a significant impact on improving air quality.
One way to reduce transport-related air pollution is to drive less. This can be achieved by opting for public transportation, biking, or walking whenever possible. Many cities are investing in better and more affordable public transportation options, as well as developing infrastructure that supports walking and biking. Combining errands into a single trip can also help reduce the number of car journeys made.
Another way to reduce air pollution from transport is to choose more efficient and less polluting vehicles. When purchasing a new car, look for options with high fuel efficiency or consider zero-emission electric vehicles. Regularly maintaining your vehicle and keeping your tires properly inflated can also help decrease fuel consumption and reduce emissions.
For longer-distance travel, consider taking the train instead of flying. Air travel has a significant carbon footprint, and choosing alternative modes of transportation can help reduce this impact. Additionally, if you are able to work remotely, you can reduce your commute and the associated emissions.
On a larger scale, supporting policies and initiatives that promote cleaner transport options can have a significant impact. This includes advocating for improved public transportation, investing in electric vehicle infrastructure, and encouraging the development of clean technologies for transport.
