The Energy Lollipop Outdoor CO₂ Signal is a public installation that visualizes community energy performance and greenhouse gas emissions in real time. Located in a prominent public space, the display transforms abstract emissions data into an easily understood visual experience that residents encounter during everyday life.

The project leverages social norms, public feedback loops, and collective identity to encourage participation in energy-saving behaviors. By making community performance visible, the installation creates a shared sense of responsibility and progress. It also provides local governments and utilities with a powerful public engagement tool that helps translate climate targets into something residents can see, understand, and influence.
