This paper attempts to identify some of the main factors affecting a hotel establishment's decision to adopt (or not), and to what extent, socially and environmentally responsible business practices. Salient among the results obtained is the fact that corporate social responsibility (CSR) is likely to be part of a hotel's product differentiation strategy; additionally, it is shown that productivity aspects such as scale economies, as well as the hotel's internal organization, also impact a hotel's CSR strategy.
