Returning in 2026–27 with two contest periods!

The Live Net Zero Classroom Challenge

The Live Net Zero Classroom Challenge is back for the 2026–27 school year with new and updated challenges—and this year, there are two opportunities to participate and win!

Canadian educators and students from Kindergarten to Grade 12 are invited to take part in this nationwide contest, which turns everyday classroom and household actions into powerful steps toward a more sustainable future.

The 2026–27 Challenge will run during two contest periods:

• Contest Period 1: September 15–December 1, 2026
• Contest Period 2: January 15–April 30, 2027

Free for all Canadian classrooms, the Challenge offers fun, hands-on, curriculum-linked activities tailored to different grade levels, with bilingual resources available for 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. Explore the activities here to find activities that could fit your classroom.

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!
