Sustainable Asset Valuation (SAVi) of River Restoration in Greece

The report evaluates three flood risk reduction scenarios in Thessaly, Greece: nature-based infrastructure (NBI), hybrid infrastructure, and grey infrastructure. Using the SAVi methodology, it finds that NBI—consisting of riparian forest and floodplain restoration—offers the highest benefit-to-cost ratio (2.9) over 25 years. Notably, the carbon storage value of NBI (EUR 12.8 million) exceeds the total implementation costs for both NBI (EUR 6.8 million) and hybrid options (EUR 9.3 million).

• Nature-based infrastructure (NBI) is the most cost-effective option over a 25-year period, with a benefit-to-cost ratio of 2.9, which is higher than the 2.4 ratio for hybrid infrastructure and 1.5 for grey infrastructure.
• The carbon storage value provided by NBI is EUR 12.8 million, a figure that independently exceeds the costs of implementing 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 the reduction in flood damages.
