Four environmental groups—the Thassos Island Environmental Association, the Pan-Thasian Coordinating Committee of Organizations, the Kavala Initiative Against CO2 Storage, and the Nestos/Prinos CCS Opposition Initiative—have coordinated a public statement raising concerns about decision-making procedures related to carbon capture and storage proposals in the region. The organizations voiced skepticism about the extent to which local communities and stakeholders were meaningfully consulted before advancing European programs in the area. The groups cited a recent presentation event on EU-funded initiatives as a focal point for their objections, suggesting that critical questions about environmental impact and public participation remain unaddressed.
