Call on Your City to #MakeEUBlue
The Ocean Starts in Our Cities – Every City Must Take Action!
Europe’s rivers and oceans are threatened by pollution, climate change, and unsustainable urban practices. Every city—whether on the coast or inland—directly impacts water ecosystems through local practices and policies.
That’s why we, the citizens, call on our city officials to commit to real action for ocean sustainability by joining the #MakeEUBlue: Cities in Action movement.
Cities across Europe are stepping up to protect our waters. Our cities can take action in many ways— from improving waste management, governance, education and restoring waterways to engaging communities and joining European initiatives.
Explore the portfolio of actions cities can take here:
Every signature brings us closer to action by showing that we, the citizens, care about protecting our waters. At 50 signatures, our first email will be sent to city officials. As more people sign, we will continue pushing for action until real commitments are made.
Sign the petition today and help bring your city on board to #MakeEUBlue!
