Residents and local organizations in Kavala and Thasos are protesting a proposed underwater carbon dioxide (CO2) storage project in the Prinos area. The investment, valued at over one billion euros, aims to store one million tons of CO2 annually in an inactive oil field during its first phase, with plans for expansion.

Two legal appeals have been filed with the Council of State to cancel the project: one by the Municipality of Thasos and another by various groups, including the Thasos Environmental Association. Protesters argue the project poses environmental risks and could negatively impact local tourism and fishing industries. Major environmental organizations, such as Greenpeace and WWF Hellas, have also expressed opposition to the technology.
