Factoring in the social cost of carbon, the savings are between $1.65-$2 million. The amount of energy saved equates to more than all of the occupied homes in Polish Hill (697 homes), Swisshelm Park (625 homes), and St. Clair (209 homes) for a year.


GWC participants reduced landfill waste by 436 tons, or 35% compared to the baseline. Total waste, which includes compostable, recyclable, and landfill materials, was reduced 517 tons or 24%. This is an increase in the diversion rate by 20%.

Greenhouse Gases:

Participants saved over 2,865 metric tons of carbon dioxide equivalent, which translates to roughly 73 airline flights of 500 miles: roughly 2/3 of a day worth of all flights leaving Pittsburgh International Airport on a typical day. Additionally, participants saved 2,700 pounds of PM 2.5 from entering the atmosphere.
