We elicit citizens' preferences for the transition towards pesticide-free management in urban green spaces.  While  the  literature  has  focused  mostly  on  the  estimation  of  preferences  for  pesticide reduction in agricultural production by farmers and food products by consumers, the originality here is to study a pesticide-free non-agricultural good. We rely on a Discrete Choice Experiment ran on-line on a representative sample of the French urban population. This method allows to study individual preferences for alternative bundles of attributes characterizing the consequences of the transition towards pesticide-free green spaces. They include the new characteristics of these green spaces of direct interest for the users, as well as less visible characteristics such as the working conditions or the budget  dedicated  to  the  maintenance  of  such  areas.  The  results  account  for  heterogeneity  in preferences. All the attributes included have a significant impact on preferences, and are consistent with the empirical and theoretical literatures.
