The City of Philadelphia does significant work behind the scenes to ensure the city’s air quality is healthy and tracks below our clean air goals. Did you know that Philadelphia has a network of 11 air monitoring sites throughout the City that measure what are known as criteria pollutants:

Ozone (O3), Carbon monoxide (CO), Nitrogen dioxide (NO2), Sulfur dioxide (SO2), Particulate matter (PM10 and PM2.5), and Lead (Pb).

Five of the sites also measure toxics, such as 1,3-butadiene, benzene, and carbon tetrachloride.

According to City of Philadelphia measurements, air quality in Philadelphia has dramatically improved over the past few decades, as evidenced by fewer unhealthy air quality days (adjusted to the current standard) during the past several years, as shown in the graphic below.  This is something to be proud of Philadelphia, keep up the good work!

How does PGW fit into improving the air quality of Philadelphia? PGW continues to be part of the solution by actively promoting the use of more efficient energy appliances and better conservation practices. Today, traditional natural gas markets in Philadelphia use less energy but achieve the same benefit.
