Returning in Fall 2026!

The Live Net Zero Classroom Challenge

We’re excited to share that the Live Net Zero Classroom Challenge will return in Fall 2026 with new and updated challenges. If you haven’t already, we encourage you to register now to stay informed about the launch, key dates, and how to participate. Teachers are also welcome to continue using the existing challenge activities at any time to support classroom learning, climate action, and sustainability initiatives.

This fall, Canadian educators and students from Kindergarten to Grade 12 will be welcome to join this nationwide contest that turns everyday classroom and household actions into powerful steps toward a sustainable future. Free for all Canadian classrooms and designed to inspire hands-on learning, the Challenge offers curriculum-linked activities tailored for different grade levels, with bilingual resources available for both elementary and secondary students.

From reducing energy use and waste to rethinking transportation, food choices, and celebrations, each challenge encourages students to take real action—at school, at home, and in their communities. Participating classes submit proof of their completed challenges for the chance to win cash prizes that support ongoing climate and sustainability projects at their school.

Getting started is easy: create your educator account, register your class, choose the challenges that spark your curiosity, and begin making a difference today!
