Reduce vehicle emissions: switch to electric vehicles, carpool, bike, bus, or telecommute
One of the most effective ways to reduce pollution in cities is to reduce vehicle emissions. According to the United States Environmental Protection Agency, 26% of all greenhouse gas emissions in the US are caused by transportation.
One way to reduce vehicle emissions is to switch to electric vehicles. All-electric vehicles, plug-in hybrid electric vehicles (PHEVs), and hybrid electric vehicles (HEVs) produce lower tailpipe emissions than conventional vehicles and zero tailpipe emissions when running on electricity. While electricity production can also produce emissions, in areas with relatively low-polluting energy sources, electric vehicles have a significant advantage over conventional vehicles.
Another way to reduce emissions is to carpool. Carpooling reduces the number of vehicles on the road, which can lead to a significant reduction in emissions. Additionally, consider using a bike or taking the bus when possible. Bicycles, especially e-bikes, offer a great alternative to cars and can contribute to carbon reduction. In some areas, using an e-bike instead of a car can result in a CO2 reduction of up to 750 kg per person per year.
Finally, telecommuting can also help reduce vehicle emissions. Recent research from Global Workplace Analytics found that 50% of American workers have jobs compatible with partial telework. Telecommuters consume less fuel than those who drive or use mass transportation, leading to reduced transportation-related greenhouse gas emissions.

Cut energy use: choose efficient appliances, turn off electrical items, and get an energy audit
Energy use is a significant contributor to pollution in cities. Here are some ways to cut energy use and combat pollution:
Choose efficient appliances
When purchasing appliances, it's important to consider both the initial purchase price and the annual operating cost. Energy-efficient appliances might have a higher upfront cost, but they usually save money in the long run by reducing energy consumption and electricity bills. Look for the Energy Star label, which guarantees that the appliance will consume less energy than standard models. For example, replacing an old refrigerator with a new Energy Star model can save over $100 per year on electric bills. Similarly, upgrading to energy-efficient light bulbs, such as LED bulbs, can reduce lighting costs, which account for about 10% of your electric bill.
Turn off electrical items
Turning off electrical items when they are not in use is crucial for reducing energy consumption. Devices with standby modes can still sap power, accounting for up to 10% of your electricity costs. To address this, use power strips to easily cut power to multiple devices at once, such as phone chargers, TVs, and computers. Additionally, smart plugs and relays can be used to control appliances remotely and provide real-time data on energy usage, helping you make informed decisions about your energy consumption.
Get an energy audit
Conducting an energy audit can help identify areas where energy efficiency can be improved. A professional energy audit may be worth the upfront cost, as it can lead to significant savings in the long run. However, DIY energy audits are also an option. During an audit, check for air leaks around windows, doors, lighting fixtures, plumbing fixtures, switches, and electrical outlets. Seal any gaps or cracks with appropriate materials, being mindful of potential indoor air pollution and "backdraft" issues. Additionally, consider upgrading to energy-efficient windows, such as double-pane or "low-e" storm windows, which can significantly reduce heating and cooling expenses.

Improve air quality: plant trees, avoid backyard fires, and support anti-idling policies
Improving air quality is essential for the health of a city and its inhabitants. There are several ways to achieve this, including planting trees, avoiding backyard fires, and supporting anti-idling policies.
Planting Trees
Trees are a natural way to filter pollution and improve air quality. They directly remove pollutants from the air and release oxygen into the atmosphere. Additionally, they provide shade, reducing the need for conventional air conditioning and the emissions associated with it. When choosing which trees to plant, it's important to consider the local context and seek advice from experts. Some trees are more effective at filtering pollutants than others, so selecting the right species for the specific urban environment is crucial. For example, in Beijing, tree-planting schemes are being implemented to combat the city's poor air quality, and Paris is planning an urban forest to improve air quality and adapt to climate change.
Avoiding Backyard Fires
Backyard fires are a significant source of air pollution, especially in urban areas with higher population densities. Smoke from these fires can cause unhealthy conditions for many people, especially those with asthma and other lung conditions. It is recommended to limit or avoid backyard fires, especially during stagnant weather conditions. If a fire is necessary, keep it small and brief, and consider alternatives like trash hauling services for waste disposal. Additionally, be mindful of the health risks associated with cleaning up ash and debris, and follow guidelines to protect yourself and your family.
Supporting Anti-Idling Policies
Idling engines, especially from buses and large trucks, create hotspots of unhealthy pollution. Implementing and enforcing no-idling policies can significantly improve air quality. Parents and teachers can play an active role by encouraging schools and daycares to adopt and implement such policies. Additionally, individuals can do their part by turning off their engines when possible and reducing their overall fuel consumption.
By combining these strategies and focusing on improving air quality, cities can become healthier and more sustainable places to live. It is important to note that local governments and officials also have a crucial role in passing ordinances, creating incentives, and educating residents on best practices to reduce air pollution.

Sustainable consumption: use reusable containers, shop local, and buy from farmers' markets
Sustainable consumption is a key way to reduce pollution in cities. This involves making thoughtful choices about what we buy, where it comes from, and how it is packaged.
One way to achieve this is to use reusable containers. Single-use plastics are a significant source of pollution, so opting for reusable alternatives can substantially reduce waste. Containers made from bamboo or glass, for instance, are environmentally friendly and safe options.
Shopping locally is another effective way to reduce pollution. Local farmers' markets are a great way to support local farmers and reduce the environmental impact of food production and transport. Typically, food in supermarkets travels over 1,000 miles from production to the store, whereas farmers' markets often limit vendors to selling food produced within 200 miles. This significantly reduces the carbon footprint of the food we buy. Moreover, farmers selling at markets tend to minimise waste and pollution, with many adopting organic practices and low-impact methods such as on-site composting.
Farmers' markets also provide an opportunity for sustainable economic growth. They allow farmers to make a living from sustainably grown food and foster a mutually beneficial relationship between farmers and the local community. This economic support is vital for farmers who face challenges in a corporate-dominated industry.
In addition to farmers' markets, shopping at local businesses in general can help reduce pollution. This not only shortens travel distances and reduces emissions but also encourages local businesses to adopt sustainable practices.

Business practices: direct local businesses towards programs that reduce waste and emissions
Local businesses can be directed towards programs that reduce waste and emissions in several ways. Firstly, it is important to educate business owners and employees about environmental laws, regulations, and policies related to pollution-causing materials and activities. This includes understanding the impact of their waste on the environment and the potential for waste reduction. Waste assessments or audits can help businesses identify the quantity and composition of their waste, enabling them to tailor waste reduction strategies effectively. Local governments and waste haulers sometimes offer free waste audits, and tools like ENERGY STAR Portfolio Manager® can assist in tracking waste, energy, and water data.
Secondly, businesses should be encouraged to implement recycling programs and adopt energy-efficient practices. This includes simple measures such as recycling office supplies and using email receipts instead of printed ones. They can also invest in renewable energy technologies, create water conservation plans, and design products with recyclability in mind. Additionally, businesses can look into community composting initiatives or local composting organizations to further reduce their waste output.
Thirdly, businesses can be incentivized to reduce waste and emissions by understanding the cost savings and improved operational efficiency that comes with pollution prevention. Reducing waste can lower disposal costs and energy consumption, while also enhancing their brand reputation and attracting environmentally conscious customers. Regulatory compliance can also help businesses avoid fines, legal actions, and reputational damage associated with environmental laws and standards.
Lastly, local governments can play a role by passing local ordinances, creating incentives for beneficial behaviors, and promoting and educating residents on best practices. For example, the Small Business Environmental Assistance Program in Minnesota helps businesses comply with environmental rules, reduce waste and emissions, and reduce regulatory obligations.
