Let’s find solutions together!
Sustainability challenges are complex. But what if you could have several world-class, diverse teams dedicated to solving yours? At Global Green Action Day, your organization has a unique opportunity to gain fresh perspectives and expert-driven solutions to your most pressing sustainability challenges.
Through the diverse expertise of the teams, combined with the knowledge acquired during pre-training, organizations can receive valuable input and actionable ideas to accelerate their sustainability transformation.
These challenges will allow teams to apply their expertise in innovation strategy, circular economy, and AI for sustainability. While this year’s UN World Environment Day theme is “Ending Plastic Pollution”, we welcome all sustainability challenges—from circular solutions and sustainable materials to broader environmental and social impact challenges.

example challenge
What to do with collected Microplastics?
Up to 9 000 000 microplastics can be released in one single wash of laundry. These particles can be captured by filtering the gray water. But can these microplastics be repurposed for something that creates value? Or be removed from our environment completely?
