Guess the Date Contest for Schools

Use Global Footprint Network’s open data platform and other information available on this website to explore, grab, and use relevant data in order to come up with your best estimate for Earth Overshoot Day 2019, the date when we have used all the renewable natural resources that the planet can replenish this year.

We also created these guidelines to turn this activity into a full lesson for Grades 6-8.

Are you not a teacher or a student? This contest is open to you too! Just go here to submit your entry.

May 22, 2019 (International Day for Biological Diversity 2019) is the deadline to submit your calculation methodology and result.

The winner, as well as the date of Earth Overshoot Day 2019, will be announced on June 5. Read about 2017’s winners here.
