Reduce energy use, transport, and services to lower harmful emissions
Reducing energy use is one of the most effective ways to lower harmful emissions. This can be achieved through simple everyday choices, such as turning off electrical appliances and lights when not in use, and opting for more energy-efficient solutions. The U.S. EPA's ENERGY STAR Program, for example, provides the technical information and tools needed to choose energy-efficient solutions.
On a larger scale, the U.S. EPA's Combined Heat and Power Partnership (CHP) Resource Center helps facilities reduce the environmental impact of power generation and increase operational efficiency. Similarly, the U.S. EPA's Green Power Partnership (GPP) is a voluntary program that encourages organizations to use green power to reduce the environmental impacts associated with conventional electricity use.
Transport is another major contributor to harmful emissions. Motor vehicle emissions are the most significant source of common air pollutants. To reduce emissions from transport, individuals can opt for fuel-efficient vehicles, such as electric or hydrogen fuel cell vehicles, which emit zero harmful tailpipe emissions. Improving engine and tyre efficiency, as well as reducing vehicle weight, can also contribute to lower emissions.
Additionally, walking or riding a bike instead of driving for short distances can significantly reduce emissions. For freight transportation, the U.S. EPA's SmartWay program helps freight shippers, carriers, and logistics companies improve fuel efficiency and reduce emissions.

Use less toxic chemicals and modify production processes to reduce waste
Green chemistry is a concept that promotes the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. It involves creating chemical products that are effective yet have little to no toxicity. This approach can be applied to the design, manufacture, use, and disposal of products.
One way to reduce toxicity is to use safer solvents and reaction conditions. This involves avoiding solvents, separation agents, and auxiliary chemicals whenever possible, and opting for safer alternatives when necessary. For instance, the chemical treatment of waste containing carcinogens initially used strong oxidants like potassium permanganate. A shift to less harmful oxidants like sodium hypochlorite (bleach) proved to be more effective and safer. Additionally, renewable feedstocks, such as agricultural products or waste from other processes, can be used instead of depletable feedstocks like fossil fuels.
To minimize waste, catalytic reactions can be employed. Catalysts are highly effective, even in small amounts, and can facilitate the same reaction multiple times. This makes them preferable to stoichiometric reagents, which are used in excess and can only be used once. Furthermore, designing chemicals that degrade after use is essential. These chemicals break down into innocuous substances, ensuring they do not accumulate in the environment.
Industries can play a significant role in reducing pollution by modifying their production processes. They can benchmark their emissions against similar facilities and implement cleaner production techniques to reduce substance emissions and waste. For instance, the Toyota vehicle manufacturing facility in Altona, Victoria, successfully introduced innovative solutions to reduce emissions. Additionally, industries can utilize specific chemical treatments to reduce the hazardous nature of waste. This involves using chemicals like acids, bases, oxidizers, and reducers to treat waste and recover valuable byproducts, thereby reducing disposal costs.
Lastly, individuals can contribute by properly disposing of household chemicals and motor oil. Never pour chemicals on the ground or into storm drains, as they can contaminate nearby water bodies. Recycling plastic, glass, and paper are also essential to reducing the waste stream, a critical goal in controlling nonpoint source pollution.

Recycle plastic, glass, and paper to reduce the waste stream
Recycling plastic, glass, and paper is an effective way to reduce the waste stream and prevent pollution. In 2018, Americans recycled about 68% of the paper they used, amounting to almost 94 tons of municipal solid waste. Paper makes up 23% of municipal solid waste generated each year, more than any other material. Recycled paper is used to make new paper products, conserving trees and other natural resources. Most community or office recycling programs accept paper and paper products, including newspapers and magazines. However, it is important to check with local programs, as some may have different rules. Individuals can also contribute by reducing their paper consumption and opting for products made from recycled paper.
Glass, especially glass food and beverage containers, can be recycled endlessly. In the United States, 31.3% of the 12.3 million tons of glass generated in 2018 was recycled. Recycled glass is more cost-effective than using raw materials to produce new glass. However, it is important to separate glass from other recyclables. Metal bottle caps, for example, should be recycled separately from glass bottles.
Plastic recycling is more complex and challenging. Only 9% of all plastic waste ever created has been recycled. Mechanical and chemical recycling methods, such as pyrolysis and gasification, exist, but they have environmental and health concerns due to the release of toxic fumes. Additionally, different types of plastics, like polyethylene and polypropylene, must be completely separated during recycling to create usable new products. Despite these challenges, recycling plastics saves 70% of production energy, according to the National Institute of Health's Environmental Management System. It is crucial to check with local recycling programs to understand the specific types of plastics they can collect and recycle.
Overall, recycling plastic, glass, and paper plays a crucial role in reducing the waste stream and preventing pollution. Individuals can actively contribute by familiarizing themselves with local recycling guidelines, properly separating and cleaning recyclables, and reducing their consumption of single-use materials.

Plant trees, grass, and shrubs to absorb rainwater and prevent runoff
Planting trees, grass, and shrubs is a highly effective method of absorbing rainwater and preventing runoff. Vegetation in bare areas helps to reduce and absorb runoff, while also preventing soil erosion by holding the soil together with their roots.
Trees are particularly beneficial in managing stormwater runoff. Their leaf canopies reduce erosion by providing a surface area for rainwater to land and evaporate. Additionally, their roots take up water and create conditions in the soil that promote infiltration.
Grass and flowering perennials can be strategically planted in rain gardens, which are depressed areas designed to collect rainwater from roofs, driveways, or streets and allow it to soak into the ground. These gardens not only reduce runoff but also act as natural filters for pollutants, providing food and shelter for wildlife.
When selecting trees, shrubs, and plants, it is essential to consider water consumption. Certain plants, like cacti, absorb less water and may not be suitable for rain gardens. Consulting a landscaper can help in choosing the right plants for your region and addressing specific drainage issues.
In addition to planting vegetation, individuals can take other measures to reduce pollution. This includes recycling plastic, glass, and paper, properly disposing of motor oil and household chemicals, and minimizing the use of cars for transportation.

Use electric vehicles, carpool, or bike to reduce vehicle emissions
Motor vehicle emissions are the most significant source of common air pollutants. To reduce vehicle emissions, individuals can opt for electric vehicles, carpool, or switch to biking.
Electric vehicles (EVs) are a popular choice for reducing vehicle emissions. While EVs do not have tailpipe emissions, the electricity used to charge them may create carbon pollution, depending on the energy source. In 2020, renewable energy sources like wind and solar became the second-most prevalent electricity source in the US, and as a result, the total greenhouse gas emissions associated with EVs are typically lower than those of gasoline cars. Additionally, EVs are more energy-efficient, using 87-91% of battery energy for propulsion compared to gasoline vehicles' 16-25% energy conversion. Moreover, EVs can be charged at off-peak times, such as overnight, when rates are often cheaper, and this can help manage the increase in EV charging as more renewable energy sources are adopted.
Another way to reduce vehicle emissions is by switching to e-bikes, which have been shown to offer significant CO2 saving capabilities. Spatial microsimulation studies in England found that the maximum capability to reduce CO2 by substituting car travel with e-bike use is 24.4 MTCO2 per annum, with the highest savings per person in rural areas and the rural-urban fringe.
Carpooling is also an effective way to reduce vehicle emissions. By sharing rides, individuals can decrease the number of cars on the road, thereby reducing emissions.
Finally, individuals can opt to walk or bike to their destination instead of driving. This not only reduces vehicle emissions but also provides health benefits through physical activity.
