Case Study: City of Stockholm achieves improved water quality valuation with Anthesis

City of Stockholm Inland Waters Valuation

The City of Stockholm's Environment and Health Administration wanted to understand the economic value of achieving good water quality in its inland waters, as defined by the EU Water Framework Directive. The city engaged Anthesis to conduct a monetary valuation of the benefits and analyze the relationship between the costs of necessary measures and the resulting benefits.

Anthesis implemented a large-scale, web-based survey targeted at the general public to determine their willingness to pay for improved water quality. Using established valuation methodology, Anthesis estimated the monetary benefits. The outcome was an estimated economic value of SEK 2.5–2.8 billion, indicating socio-economic profitability. The project delivered a crucial analysis for the city's action plan and generated positive public response and media attention.
