The objective of this study is to determine the factors that explain the orientation, of the wine industry and at firm level in Portugal and Spain for adopting policies to improve sustainability, identifying similarities and differences between the two countries. The study focuses on two countries that account for a relevant part of the global vineyard surface area, wine production and wine exports. The database for the empirical analysis has been constructed through a survey conducted among wineries of the two countries during 2020 and 2021, for which a total of 568 valid responses were obtained, 151 in Portugal and 417 in España. From the quantitative analysis, based Box-Cox left-hand-side models, one for each country, it can be concluded that those wineries that invest the most in their growth, anticipate future challenges and interact with interest groups are more inclined towards adopting sustainability measures. The study also reveals notable differences between the two countries as the determinants that drive sustainability, finding that sustainability policies are not unit and specific common vectors
