Cyprus Leads Europe with 99.2% Clean Beaches — Greece Close Behind at 97%

Cyprus ranked first in the entire EU for bathing water quality in 2024, with 99.2% of its monitored coastal sites rated "excellent" by the European Environment Agency — a standard it has held for three consecutive years. Greece ranked third at 97%, with 623 beaches earning the prestigious Blue Flag designation in 2025. Across 22,000+ monitored sites in 29 countries, 85% of Europe's bathing waters now meet "excellent" standards — a direct result of decades of EU wastewater legislation and national investment.

EU Launches €15 Billion Water Strategy with Mediterranean at the Centre

The European Commission adopted its landmark European Water Resilience Strategy in June 2025, committing €15 billion in EIB financing over 2025–2027. The strategy explicitly identifies Mediterranean countries — Spain, Portugal, Greece, Cyprus, France, and Malta — as climate hotspots requiring dedicated water resilience measures: nature-based solutions, drought preparedness, expanded water reuse, and tackling PFAS and pharmaceutical contamination. A first EU Water Resilience Forum convened in December 2025 to accelerate implementation.

Salmon Return to Spain's Basque Rivers as Historic Dam Removal Opens 8km of Habitat

The 120-year-old Galtzaraberri dam on the Karrika River in Spain's Basque Country was fully demolished, reopening 8 kilometres of river for fish migration for the first time in more than a century. Atlantic salmon were spotted upstream within months of removal — the result of careful community engagement, including 670 local schoolchildren. Spain removed a record 96 river barriers in 2025 alone, cementing its status as a European leader in river restoration.
