This paper assesses the economic value of green infrastructure using a contingent valuation questionnaire to establish willingness to pay for specific urban greening investments. The paper presents analysis of 510 face-to-face interviews with residents, commuters, employees and other users in the Wicker Riverside area of Sheffield, UK. The willingness to pay question was framed as a regular monthly increase in rent or mortgage for a two-bedroom apartment. 3D visualizations showing seven alternative green infrastructure investment scenarios were developed for two sites within the study area. Analysis of the socio-economic profile and behavioural preferences of respondents suggests that we can model economic evaluation of green investments willingness to pay and increase our understanding of how the urban landscape can promote a better quality of place.
