Karlijn - Student Environment and Resource Management

Karlijn - Student Environment and Resource Management

So many of us want to contribute to a sustainable world, but it can feel like our individual actions have little impact. But what if 1000's of people take the same action as you at the same time? Sustainability is close to Karlijn's heart and now she's helping others in making sustainable choices too. The CollAction app connects conscious people and gives tips on how to fight for the Sustainable Development Goals together.

Do you want to make the world a better place, but your actions feel like a drop in the ocean? Thanks to crowdacting you can take action together and at the same time with many like-minded people. You act with a group synchronously for the same goal, reinforcing your individual action.

Let's not eat meat for a month together. Let's reduce our plastic use together. Let's not buy new clothes for a season.
