Sustainable Asset Valuation (SAVi) of River Restoration in Greece

This report uses the Sustainable Asset Valuation (SAVi) methodology to compare nature-based, hybrid, and grey infrastructure for flood risk management in Thessaly, Greece. It finds that nature-based infrastructure (NBI) offers the highest benefit-to-cost ratio (2.9) over 25 years, with carbon storage value alone (EUR 12.8 million) exceeding the costs of NBI and hybrid options.

• Over a 25-year period, nature-based infrastructure (NBI) provides the highest benefit-to-cost ratio at 2.9, which is higher than the 2.4 ratio for hybrid infrastructure and the 1.5 ratio for grey infrastructure.
• The carbon storage value of NBI is estimated at EUR 12.8 million, a figure that exceeds the implementation costs for both NBI (EUR 6.8 million) and hybrid infrastructure (EUR 9.3 million).
• Investment in NBI is justified by additional benefits such as avoided emission costs and increased agricultural production, even before accounting for avoided flood damages, which would further increase net benefits during extreme events.
