Celebrating eco awareness days throughout the year helps keep environmental issues front of mind, inspires positive action, and reminds us that protecting the planet is a shared responsibility.

These days encourage learning, reflection, and community involvement, while giving us opportunities to celebrate progress, raise awareness, and motivate change for a more sustainable future.

Whether you’re a teacher looking for ideas, planning an event for a youth group or just planning your own Instagram feed, there are plenty of opportunities to get involved.
