Improving air quality by reducing vehicle emissions and idling, and choosing cleaner energy sources
Philadelphia has taken steps to improve air quality and reduce pollution from vehicle emissions and idling by investing in clean energy and energy efficiency projects. The Philadelphia Energy Authority (PEA), with the support of City Council President Darrell Clarke, launched the Philadelphia Energy Campaign in 2016. The campaign aims to create jobs, strengthen communities, reduce energy bills, and lower Philadelphia's carbon footprint.
The PEA is investing $1 billion in public and private financing across four key sectors to promote clean energy and energy efficiency. One of the initiatives under this campaign is Solarize Greater Philadelphia, a program that helps Philadelphians transition to solar energy.
The city's efforts seem to be paying off. According to the Office of Sustainability's 2019 Greenhouse Gas Inventory, Philadelphia's emissions decreased by 20% compared to 2006 levels. This reduction was attributed to a cleaner electricity grid, with electricity generation from coal decreasing from 45% in 2006 to 12% in 2019. While electricity use in buildings and industries declined slightly, natural gas use and corresponding emissions increased, particularly in the residential sector.
Transportation emissions, however, pose a challenge. Since 2006, transportation emissions have increased by 5% due to a rise in Vehicle Miles Traveled, possibly linked to population growth in the city. To address this, Philadelphia can encourage the use of public transportation, electric vehicles, and implement initiatives to reduce vehicle idling, such as optimizing traffic signal timing and promoting anti-idling practices.

Cleaning up contaminated soil at former industrial sites to prevent health risks
Philadelphia has a long history of industrial pollution, with the city's first environmental laws being imposed in 1763 due to the dumping of waste into Dock Creek. Today, the city still struggles with the legacy of industrial pollution, with several former industrial sites requiring remediation to prevent health risks to residents.
One notable example is the Clearview Landfill, where the city of Philadelphia built a neighbourhood on top of contaminated soil. The landfill was declared one of the nation's most contaminated Superfund sites, requiring an extensive cleanup process. The city has since removed and replaced contaminated soil from approximately 150 homes in the area, with the main remediation plan estimated to cost $76.2 million.
Another former industrial site requiring cleanup is the 57-acre Enterprise Avenue Superfund site. From 1971 to 1976, the city used the area for waste disposal, resulting in soil and groundwater contamination. The EPA added the site to the National Priorities List (NPL) in 1983 and oversaw its cleanup, which included removing contaminated soil and capping the landfill.
The Publicker Industries Inc. Superfund site is another example, located along the Delaware River. The company produced liquor and industrial alcohols at the site and later used it for chemical storage. After abandonment, the EPA added the site to the NPL in 1989 and conducted a cleanup involving removing contaminated debris and soil, capping and sealing groundwater wells, and removing asbestos from buildings.
The Clean Air Council plays an active role in advocating for protective cleanup standards at former industrial sites to ensure the safety of residents and the environment. They have urged companies like Sunoco to improve their cleanup standards, specifically regarding lead contamination in soil.
Overall, cleaning up contaminated soil at former industrial sites is crucial for preventing health risks to Philadelphia residents. The city and organisations like the Clean Air Council are working towards remediating these sites, improving air and water quality, and protecting the well-being of the community.

Improving water quality by reducing stormwater runoff and preventing sewer overflows
Philadelphia has a history of pollution, from the early days of European colonization to the present. The city has taken several steps to improve its air and water quality, and there are also actions that individuals can take to help reduce pollution.
One way to improve water quality is by reducing stormwater runoff and preventing sewer overflows. The Philadelphia Water Department's Rain Check program provides residents with free barrels or discounted downspout planters to help manage stormwater. Residents are also advised to avoid showering or using appliances such as dishwashers or washing machines during rainstorms to prevent sewer overflows. These simple actions can help keep the city's rivers and streams clean while also protecting neighbourhoods from flooding.
The city has also acquired private estates along the Schuylkill River to establish Fairmount Park, creating a buffer between the industrial city and the wooded hinterlands. This prevents effluent from industries such as coal-heaving and iron founding from entering the creeks and rivers.
Philadelphia has also updated its regulations on toxic air pollution from industrial facilities, addressing compounds like asbestos, lead, arsenic, and cancer-causing benzene. The Clean Air Council is working to decrease air pollution at newly proposed shipping hubs, urging the city to apply the "Complex Air Pollution Permit" to large transportation pollution sources.
Individuals can also play a role in reducing pollution by composting food scraps, limiting car usage, and choosing renewable energy suppliers.

Increasing composting and reducing food waste to prevent landfill
Philadelphia, the largest city in the US state of Pennsylvania, has a long history of pollution. From the early days of European colonisation to the present, the city has struggled with various forms of pollution, including air, water, and waste pollution. In recent years, Philadelphia has made significant strides in improving its air quality, but there is still much to be done to address the issue of pollution and its impact on public health and the environment.
One key strategy to reduce pollution in Philadelphia is to increase composting and reduce food waste. The City of Philadelphia encourages residents to compost their food scraps instead of sending them to landfills. Composting is a natural process of recycling organic materials, such as food scraps and yard waste, into a rich soil amendment that can be used to improve soil health and fertility. By composting, residents can divert food waste from landfills, reducing the amount of methane gas emitted into the atmosphere. Methane is a potent greenhouse gas that contributes to climate change and global warming.
The City of Philadelphia offers resources and programmes to make composting more accessible to its residents. For example, residents can build their own indoor compost bins or use third-party pick-up services to collect their food waste for composting. The Food Policy Advisory Council also holds a design competition for scalable and innovative compost bin designs. Additionally, the Philadelphia Water Department's Biogas Cogeneration Facility turns organic waste into energy, providing an alternative to landfilling waste.
To further reduce food waste, the City encourages residents to make the most of the food they buy. This includes using leftover scraps to create stocks and soups and planning meals to minimise waste. By reducing food waste, Philadelphia can decrease the amount of waste sent to landfills, reducing methane emissions and improving the city's environmental footprint.
Increasing composting and reducing food waste are essential components of Philadelphia's efforts to become a more sustainable city. By implementing these practices, the city can reduce landfill waste, improve air and soil quality, and contribute to the global fight against climate change. Residents play a crucial role in this endeavour by adopting composting practices and reducing their food waste, ultimately helping to create a greener and healthier Philadelphia for all its residents.
