Together we can deed for the planet.

The world needs more climate action. Whether it's through concrete actions or by educating ourselves, every step counts.

In this tailored challenge, you will get the opportunity to learn more about the actions we take to make a better mark, and what you can do yourself. We hope to give you a powerful and engaging experience to raise awareness about one of the most important matters of our time.

Our main sustainability goal at Deedster is to reduce our carbon footprint. Our hope is that you will do the same. 

How &


Which team can make the greatest mark on the planet? During 3 weeks, divided in teams, we compete in doing good deeds for the planet. In the Deedster app, you calculate your own carbon footprint, get quizzed on sustainability, and do deeds to reduce your carbon footprint. The app's leaderboard will help you keep track of your progress and the competition.
