The IDREA Climathon is a reminder that when we change these small, daily actions, and take positive steps together, we create a powerful wave of climate action.

Why Climate action is important

?

"Climate change is the defining challenge of our time.
We all share a social responsibility to act.
The IDREA Climathon transforms that responsibility into action, turning every step towards a cleaner planet."
