Beyond New York

We consider the UN2023 Water Conference in New York City as a milestone, but not the finish line. We need to create more climate awareness and carry out our ideas if we want to meet the SDG deadline of 2030. That’s why our Challenge does not stop in 2023! 

Let’s keep connecting our passion for water with local communities and our global network of students, athletes, and young professionals. Our wave of impact will go on for the rest of this decade! Learn more about our plans ‘Beyond New York’ here
