Frequently Asked Questions

How do I get started?

Begin by joining the challenge through the JouleBug app and choosing one small habit. From there, you can invite coworkers, friends, or family members to participate. In just a few weeks, you’ll see how meaningful your daily actions can be by creating a more sustainable, nourishing holiday season together.

Why does food waste matter, especially during the holidays?

The holiday season brings an abundance of cooking, gatherings, and leftovers—but also one of the highest peaks in food waste. Over one-third of all food produced globally is never eaten, contributing to nearly 4.9 billion metric tons of CO₂e each year. Reducing food waste during this time helps conserve water, energy, land, and labor while supporting communities facing hunger.

Learn more about food waste in this JouleBug article. 

How does my participation make an impact?

By forming small, consistent habits—like better meal planning, storing food properly, or repurposing leftovers—you directly reduce waste and emissions. Every action logged in the challenge helps protect the climate, strengthens food security, and prevents nutritious food from being thrown away.

What kinds of actions will I take in the challenge?

The challenge focuses on simple, achievable daily habits, including:

  • Plan Smarter: Shop intentionally and use leftovers creatively

  • Store Better: Organize by expiration date and learn proper produce storage

  • Get Creative: Turn scraps into soups or stocks, and share surplus food.

These steps make sustainability easy and immediately actionable. Learn more about the challenge and different actions you can take in this JouleBug blog!

Can businesses or teams participate?

Absolutely! Organizations can form teams to boost engagement and collective impact. Encouraging employees to reduce food waste supports corporate sustainability goals, contributes to net-zero strategies, and strengthens community well-being.
