• Advocate for clean air initiatives and support local businesses, city offices, and schools in adopting sustainable practices.
• Educate yourself and others about the importance of reducing energy consumption and its impact on air quality.

Limit vehicle usage

Motor vehicles are a significant source of air pollution. In the United States, the number of cars and trucks increased dramatically after World War II, leading to a significant rise in air pollution, particularly in cities. This trend has had serious implications for public health and the environment. To limit vehicle usage and reduce air pollution, consider the following strategies:

Reduce the number of trips in your car: Consolidate errands or trips whenever possible. This can be achieved by planning your trips in advance to optimise your route and avoid unnecessary detours. Carpooling is also an effective way to reduce vehicle usage by sharing rides with others who are travelling along the same route.

Utilise public transportation, biking, or walking: Opt for public transportation, such as buses, trains, or subways, whenever feasible. These options can significantly reduce the number of private vehicles on the road. Additionally, consider biking or walking to your destination, especially for shorter distances. This not only reduces air pollution but also provides health benefits and contributes to a more active lifestyle.

Choose fuel-efficient and environmentally friendly vehicles: When purchasing a vehicle, prioritise fuel efficiency and select the most efficient model that meets your needs. Electric, hybrid, and compact fuel-efficient gas vehicles are more environmentally friendly alternatives. These vehicles emit fewer harmful by-products of combustion, reducing air pollution.

Maintain your vehicle and keep it in good repair: Regular maintenance and proper vehicle care are essential for reducing emissions. Follow the manufacturer's recommendations for maintenance and service, including regular oil changes and tune-ups. Ensure that your vehicle's emission controls are functioning properly, as newer vehicles have complex emission controls designed to minimise pollution.

Avoid unnecessary idling: Unnecessary idling of vehicles, such as cars, trucks, and buses, contributes to air pollution and wastes fuel. Modern vehicles do not require prolonged idling or "warming up" during cold weather, so turn on the engine only when you are ready to drive. Reducing idling time can lower greenhouse gas emissions and improve fuel efficiency.

By implementing these strategies, we can significantly reduce vehicle usage and contribute to cleaner air and a healthier environment for ourselves and future generations.

Use sustainable products

Using sustainable products is an effective way to prevent air pollution. Here are some ways to do this:

Energy Conservation

• Conserve electricity by setting air conditioners no lower than 78 degrees Fahrenheit and using a higher thermostat setting in the summer and a lower setting in the winter.
• Participate in local energy conservation programs.
• Purchase energy-efficient appliances with the ENERGY STAR label.
• Use a surge protector for multiple appliances and turn it off when they are not in use.
• Add insulation to your home.
• Wash laundry in cold water and line dry.
• Regularly maintain gas appliances and heaters.
• Use propane or natural gas barbecues instead of charcoal ones.
• Microwave or use a toaster oven for small meals.
• Use reusable dishes, utensils, and fabric napkins instead of disposable options.

Sustainable Transportation

• Opt for eco-friendly transportation options such as walking, biking, or taking public transportation like the bus or train.
• Carpool with colleagues, friends, or neighbours to reduce traffic congestion and per-person emissions.
• When purchasing a new car, choose the most efficient, lowest-polluting vehicle, or consider a zero-emission electric or hybrid car.
• Keep your car well-maintained and properly inflated to reduce fuel consumption.
• Avoid idling your car for extended periods, and turn off the engine when stationary in traffic.

Environmentally-Friendly Products

• Choose products made from sustainable and recycled materials, such as bamboo or hemp.
• Use durable, reusable grocery bags.
• Opt for environmentally safe paints and cleaning products.
• Look for products with low volatile organic compound (VOC) emissions to reduce the release of smog-forming chemicals.
• Eat locally sourced and organic food products, and support local farmers' markets.

Avoid open burning

Open burning is a significant contributor to air pollution, and it is essential to take steps to avoid it. Here are some detailed suggestions to avoid open burning and its harmful effects:

Understand the Risks and Impact of Open Burning:

Recognize that open burning poses risks to both the environment and public health. The smoke released from open burning pollutes the air, causing eye and nose irritation, coughing, headaches, and difficulty breathing. It can also lead to more severe health issues, especially for individuals with pre-existing respiratory conditions. Additionally, the ash produced during open burning can contaminate soil, groundwater, lakes, rivers, and streams, disrupting ecosystems.

Promote Decentralized Waste Management:

Support and advocate for decentralized waste management systems at the community level. This approach reduces the likelihood of waste dumping and burning. It also creates job opportunities for informal workers and can be tailored to local waste streams. Decentralized waste management helps to lower transport costs and ensures proper waste disposal, minimizing the temptation to opt for open burning.

Prevent Fires at Dumpsites:

Take proactive measures to prevent fires at dumpsites. This includes reducing unsegregated organic waste, promoting biomining of legacy waste, and collaborating with state pollution control boards to install air quality monitoring devices for real-time alerts. Proper landfill design, including systems for collecting and processing methane, can also help prevent combustion.

Explore Affordable Heating Solutions:

Work with local entrepreneurs to develop and implement affordable, accessible, and clean heating options for communities. This will reduce the reliance on open burning for heating purposes. Cities can play a vital role in this transition by providing clear intentions, implementing visible measures, and raising awareness among residents.

Follow Local Regulations and Alternatives:

Before considering any burning, always check and adhere to local regulations and guidelines. Explore alternatives to open burning, such as using designated incinerators or waste management systems. These alternatives can help ensure that waste is disposed of properly and minimize the release of toxic emissions. Remember, even during designated ""burn seasons," there are often restrictions on what can be burned and when.

Plant and care for trees

Planting and caring for trees is an effective way to improve air quality and reduce air pollution. Trees absorb carbon dioxide and release oxygen into the atmosphere, improving air quality and helping to cool the air and our homes. They also provide shade, reducing the need for conventional air conditioning and the emissions that come with it.

Trees are particularly good at removing particulate matter from the air. Particulate matter includes tiny particles of organic chemicals, acids, metals, and dust emitted from fossil-fuel-burning vehicles, factories, and construction sites. Trees also remove gaseous pollutants through the leaf stomata—the tiny pores on leaves that inhale air containing toxic pollutants.

When deciding which trees to plant, it is important to consider the local environment. In narrow streets surrounded by tall buildings, for example, planting tall trees with big canopies can prevent pollution from dispersing. In these cases, hedges or green walls are generally preferable. On broad roads surrounded by low-rise buildings, there is less risk of trapping pollutants, so both trees and hedges are viable options.

To care for trees, it is important to ensure they have adequate water, sunlight, and nutrients. Regular maintenance, such as pruning and removing dead branches, can also help keep trees healthy. Additionally, it is essential to be mindful of the surrounding area when planting trees. For example, ensuring that trees are not too close to power lines or buildings, and that their roots will not cause damage to nearby infrastructure.

Trees play a critical role in improving air quality and human health. In the contiguous United States, urban trees remove an estimated 711,000 metric tons of air pollution annually, leading to significant health benefits for communities.
