The capacity to generate value-added services in order to acquire and retain loyal clients is one of the challenges facing the hospitality sector. For this reason and because of economic realities and government policies, an ever-growing number of hotels are formally adopting certified environmental practices such as the ISO 14001. In this article, we attempt to analyze the relationship between the implementation of a proactive environmental management tool, the ISO 14001 standard, and the generation of economic revenues in the Spanish hotel industry. Also considered are the possible effects on the business results of moderating factors such as company size and the market segment where the hotel operates. Empirical economic information on 2,116 Spanish hotels was obtained from the SABI database (Iberian Balance-Sheet Analysis System) for the year 2008, during which 108 properties had ISO 14001 certification. Quantitative analysis techniques showed significant differences in the economic performance of ISO-certified hotels and those not certified, particularly for urban and beach hotels. The results showed influence of both company size and organizational factors on revenue. Only small rural hotels saw no difference in revenues due to the presence or absence of ISO certification.

In this article, we analyze the impact on hotels of the ISO 14001 environmental certification system from the customers’ perspective. Based on a comparison of customer ratings of 6,850 hotels in Spain with and without ISO 14001 certification, overall guests rate the hotels with ISO 14001 certification higher than those without the certification. These results are stronger for hotel comfort and hotel services compared with other hotel attributes. Moreover, the most significant differences were found in the upscale four-star hotels. While the study does not reveal causes for these findings, the implication is that the highest end five-star luxury hotels do not gain distinctive differentiation by having the ISO 14001 certification, while for three-star hotels, guests’ price sensitivity overrides environmental concerns. At the four-star level, however, hotels seem to be able to gain a distinct market advantage from environmental certification. For all hotels, the management discipline provided by ISO 14001 can provide a competitive advantage.

A cluster is a geographical concentration of interrelated firms. Cluster theory states that the synergies created inside the cluster (by the interactions between firms that compete and those that collaborate) enhance the productivity and innovation of firms and therefore their economic performance. While manufacturing industries have been widely studied from the clustering perspective, service clusters and specifically touristic clusters have received less attention. In this paper, we identify U.S. touristic clusters using a concentration measure, the Location Quotient. Then we check whether hotels located in touristic clusters obtain higher economic results than those hotels located in areas where the level of touristic-related business concentration does not get the critical mass to consider it a cluster (instead of reducing their benefits due to the high level of competitors nearby). Our results find significant differences between the two sets of hotels. The effect is stronger for subsegments of hotels based on their star category, location, and management structure. Specifically, we demonstrate that the differences are more pronounced within luxury and upscale hotel categories and within chain-managed hotels. The differences are less important in resort and airport locations than in small-metro/town, urban, and suburban areas. These results have important location implications for managers. They also contribute to understanding that economies of agglomeration lead to benefits from being located closely and in highly concentrated industries. But there is still a lot of research needed to better understand the relations between cooperation and competition within touristic clusters and how these enhance the economic performance of hotels.
