This interactive activity is designed for public events to engage participants in making a personal commitment to adopt zero-waste behaviors. By combining psychology, novelty, and social sharing, this activity encourages meaningful action through the principles of commitment theory, identity, and social diffusion. Participants choose a specific zero-waste behavior from a set of cards and take a fun photo to share, reinforcing their pledge and spreading awareness.

‍

Steps Involved:

1. Setup of the Event Booth
   • A booth is set up with a bowl containing 100 unique cards, each describing a zero-waste behavior (e.g., "Switch to reusable grocery bags" or "Compost your food scraps").
   • A 3D earth-shaped stand is positioned at the booth with a hole cut out for participants to put their face through, allowing for a novelty photo-op.
   • The stand is decorated to resemble the Earth and is visually inviting, designed to attract attention and engage curiosity.
2. Introduction to the Activity
   • Event staff greets participants and explains the purpose of the activity: to make a personal pledge to adopt one specific zero-waste behavior.
   • Participants are encouraged to choose a card from the bowl and read their zero-waste action.
3. Choosing a Zero-Waste Pledge
   • Participants reach into the bowl and randomly select one of the 100 cards.
   • The card details a simple zero-waste behavior (e.g., "Use a reusable water bottle" or "Opt for plastic-free packaging").
   • After selecting the card, the participant is asked to commit to trying that behavior.
4. Taking a Pledge Photo
   • Once the participant has selected their zero-waste behavior, they are invited to step up to the 3D earth cut-out stand.
   • They place their face inside the cut-out and hold their card in front of them.
   • A selfie or photo is taken with the participant's face framed by the earth, symbolizing their personal connection to the planet and their commitment to reduce waste.
5. Leveraging Commitment Theory
   • By physically selecting a card and publicly committing to a specific zero-waste behavior, participants are engaging in commitment theory, where making a public promise significantly increases the likelihood of follow-through.
   • The act of taking the photo reinforces their commitment, as they have a visual reminder of the pledge they made.
6. Sharing on Social Media
   • Participants are encouraged to share their pledge photo on social media platforms, tagging event hashtags and encouraging others to make a pledge.
   • The novelty of the earth stand and the fun photo-op helps drive social diffusion, where the idea of zero waste spreads within the participant's social network.
   • Event staff may offer an incentive (e.g., a reusable bag or a small eco-friendly gift) for participants who share their pledge on social media.
7. Follow-Up and Reminders
   • If feasible, participants can sign up to receive an email or text reminder of their pledge a few weeks after the event, reinforcing the behavior change.
   • The follow-up message may include additional tips on zero-waste living or links to zero-waste resources, helping participants stay on track with their commitment.

Key Psychological Principles in Action:

• Commitment Theory: By making a public promise to adopt a zero-waste behavior, participants feel an internal obligation to follow through.
• Novelty: The 3D earth stand and photo-op create a fun and memorable experience that participants are more likely to share and talk about.
• Identity: Taking a photo with the Earth stand connects the participant’s identity to being an environmentally responsible person, reinforcing the zero-waste behavior.
• Social Diffusion: The activity is designed to encourage social sharing, spreading the message of zero-waste behavior through participants' personal networks.
