EarthPact seeks to engage people in learning about their environmental footprint and prompt them to change their ways to reduce their ecological footprint. There are 5 physical, educational, and interactive exhibits, one for each topic area of the ecological footprint: food, shelter, mobility, goods, and services. EarthPact SF’s exhibits are located in Justin Herman Plaza in San Francisco, California and the exhibits also serve to activate the plaza, which is currently a ghost space most of the time. In addition to the series of exhibits, there’s an EarthPact app that people log into to track their footprint scores at each of the 5 stations. Each exhibit ties in a pledge to get participants to commit to change their behavior. The app allows people to complete the exhibits in one or multiple visits, track changes over time, receive reminders about their commitment to change, receive tips on how to lead a more sustainable lifestyle, and serve as a way to track metrics and see the collective impact of people’s behavior changes.
