What You'll Learn
Reduce vehicle usage and emissions
Vehicle exhaust is a major source of air pollution. To reduce vehicle usage, consider walking, biking, carpooling, or taking public transportation whenever possible. Driving less will directly contribute to reducing air pollution. When driving, observe speed limits and accelerate gradually. Getting a vehicle moving from a complete stop uses the most energy, so try to anticipate the road ahead and avoid racing from red light to red light.
When purchasing a new vehicle, opt for fuel-efficient models with low greenhouse gas emissions. Electric, hybrid, and compact fuel-efficient gas vehicles are becoming more affordable and widely available. These vehicles can help reduce pollution and save money on fuel costs. Keep your vehicle well-maintained, including regular checks on your tire pressure, to ensure it is running efficiently and emitting less pollution.
Avoid idling your vehicle, as this gets zero miles to the gallon and creates a hotspot of pollution. Modern vehicles do not require "warming up", so there is no need to turn on the engine until you are ready to drive. When refueling, do so during the early or late hours of the day when temperatures are cooler, as this helps reduce air pollution.
If you are purchasing landscaping machinery or commercial-grade equipment, look for products with advanced emissions reduction technologies, such as electronic fuel injection, which can significantly reduce pollution.

Improve industrial emissions standards
Improving industrial emissions standards is crucial to decreasing air pollution. The industrial sector contributes significantly to greenhouse gas emissions, and implementing measures to reduce these emissions is essential.
One way to improve industrial emissions standards is to enforce stricter regulations on oil and gas wells. The 2016 Methane Rule, issued by the EPA, is an example of such a regulation. This rule requires operators of new oil and gas wells to find and repair leaks, capture natural gas from hydraulically fractured wells, and limit emissions from pneumatic pumps and equipment used at natural gas transmission compressor stations. The EPA estimated that this rule would prevent the emission of 510,000 short tons of methane by 2025, significantly reducing the environmental impact of these operations. While the 2020 Methane Rule amended some of these standards, the EPA continues to work with the industry through voluntary programs to reduce methane emissions.
Additionally, the Clean Air Act has played a significant role in improving industrial emissions standards. The Act requires the EPA to establish New Source Performance Standards (NSPS) for greenhouse gas emissions from significant emitting subsectors. These technology-based standards are regularly strengthened to safeguard human health and the environment as technology advances and new pollution controls become more economically feasible. The Act also ensures that new industrial facilities are designed with good pollution control measures, leading to an overall cleaner industrial base as newer, cleaner facilities replace older ones.
Furthermore, the EPA has developed the Maximum Achievable Control Technology (MACT) standards as part of a two-phase approach to reducing hazardous air pollutants. In the first phase, the EPA sets technology-based standards for controlling emissions of air toxics from specific industry groups. The second phase, a risk-based approach, involves assessing the remaining health risks and determining if more stringent standards are necessary to protect public health and the environment.
To further improve industrial emissions standards, the EPA has implemented various programs targeting specific sectors. For example, the Diesel Emissions Reduction Program (DERA) focuses on deploying pollution-controlling technologies in diesel fleets, while the Tier 3 vehicle and fuel standards aim to reduce emissions from mobile sources. Additionally, the Locomotive and Commercial Marine Rule, as well as the North American and Caribbean Emission Control Areas (ECAs), address emissions from ships and marine vessels.
Lastly, adopting more sustainable practices in the industrial sector can significantly improve emissions standards. This includes increasing energy efficiency, fuel switching to less polluting alternatives, implementing combined heat and power systems, utilizing renewable energy sources, and improving the efficient use and recycling of materials. By transitioning to more sustainable practices, industries can reduce their environmental footprint and contribute to cleaner air.

Switch to clean energy appliances
The World Health Organization (WHO) estimates that 92% of the world's population lives in areas where local air pollution exceeds the recommended limit. Energy efficiency is key to reducing air pollution, as it reduces the demand for electricity generation and, therefore, reduces air pollution.
Switching to clean energy appliances is a great way to reduce your carbon footprint and improve air quality. Here are some ways to do this:
Choose efficient appliances and heating systems
Look for products with the Energy Star label, as these often offer eco settings that reduce the energy and water necessary to run them. Examples include smart appliances, LED light bulbs, and Energy Star-rated laundry machines.
Insulate your home
Insulation helps to reduce the demand for space heating in cool climates. Insulate your water heater and any accessible hot water pipes. Ensure your home is well insulated by installing double-glazed windows and insulated walls and roofs.
Utilize natural light and ventilation
Use natural light instead of artificial lighting whenever possible. Open windows and doors to improve ventilation and reduce the need for air conditioning. Chimneys, hoods, and other forms of ventilation can also reduce exposure to smoke indoors, but be mindful that smoke vented outdoors can contribute to outdoor air pollution.
Adopt clean technologies and fuels
Transition to cleaner technologies and fuels for cooking, heating, and lighting. Examples include electric or push lawnmowers, electric vehicles, and natural substitutes for toxic chemicals.
Support government policies and incentives
Advocate for and take advantage of government policies and economic incentives that support the transition to clean energy. This includes conditional cash transfers, subsidies, and tax credits for the adoption of clean energy sources and appliances.
By switching to clean energy appliances and following the above steps, you can help reduce air pollution and improve the health of both the planet and its inhabitants.

Plant and care for trees
Planting and caring for trees is a great way to decrease air pollution. Trees absorb airborne chemicals and release oxygen through their leaves, acting as the Earth's natural air purification system. They also provide shade, reducing the need for conventional air conditioning and the emissions that come with it.
To plant a tree, start by choosing the right tree for the job. Different species of trees have different abilities to filter pollutants, so research which trees are best suited to your local environment and needs. Consider factors such as canopy size, leaf size, and leaf structure, as bigger canopies and larger leaves can trap more particles. Also, look for trees with rough, rugged, and hairy leaves, as these tend to be the best filters.
Once you've selected your tree, find a suitable location with enough space for the tree to grow and thrive. Dig a hole that is twice as wide as the tree's root ball and just deep enough so that the root flare, where the tree starts to widen at the base of the trunk, is above the surrounding soil. Place the tree in the hole and backfill with soil, gently packing it down as you go. Water the tree thoroughly to settle the soil and remove any air pockets.
Caring for your tree is essential to ensure its survival and promote healthy growth. Regular watering is crucial, especially during the tree's first few growing seasons. Pay attention to the soil moisture and water when the top few inches of soil are dry. Deep watering is generally better than frequent shallow watering, as it encourages deeper root growth.
Pruning your tree is also important for its long-term health. Prune away any dead, diseased, or damaged branches to prevent decay and insect infestation. Proper pruning also helps shape the tree and promote healthy growth. Consult a certified arborist if you're unsure about how to prune your tree properly.
By planting and caring for trees, you're not just improving the air quality but also contributing to a range of other benefits, including providing food and shelter, relieving stress, promoting jobs, and helping to cool our homes.

Avoid burning trash
Burning trash is a common practice, especially in the absence of systematic waste collection. However, it is a significant contributor to air pollution and has severe health and environmental implications.
Trash fires produce smoke, which can contain harmful chemicals and particulate matter, including PM2.5 and PM10, carbon monoxide, dioxins, furans, and black carbon. These pollutants are released directly into the atmosphere, affecting air quality and posing risks to human health. The smoke can cause eye and lung irritation, headaches, dizziness, coughing, wheezing, asthma attacks, and, in extreme cases, even death. The pollutants can also settle on vegetables and soil, leading to further exposure through ingestion.
To decrease air pollution and protect human health, it is crucial to avoid burning trash. Instead, proper waste management systems should be implemented. This includes promoting decentralized waste management at the community level, ensuring door-to-door collection of all types of waste, and providing incentives for waste separation and recycling. Additionally, measures should be taken to prevent fires at dumpsites by reducing organic waste and promoting the biomining of legacy waste.
By addressing the root causes of waste burning and implementing sustainable waste management practices, we can significantly reduce air pollution and create a healthier environment for ourselves and future generations.
