This project introduces a simple, yet effective tool to encourage car owners to choose more fuel-efficient or electric vehicles by utilizing color-coded stickers. The concept, based on disclosure theory, involves the DMV requiring vehicles to display a small colored sticker on the dashboard or license plate that indicates the car’s fuel efficiency rating.

Key Features:

• Color-Coded Fuel Efficiency Sticker:
  • A simple visual indicator where colors represent different levels of fuel efficiency, with green for highly efficient or electric vehicles and red for lower efficiency.
• Public and Owner Transparency:
  • The sticker is visible to both the car owner and the public, creating subtle social pressure and encouraging conscious choices about vehicle fuel economy.
• Behavioral Nudge:
  • By using a small, non-intrusive visual cue, the tool leverages behavioral science to nudge drivers toward more environmentally friendly vehicle options.

This low-cost, high-impact tool taps into social signaling to subtly persuade car owners to make more sustainable vehicle choices, contributing to long-term energy efficiency improvements.
