This study utilizes data collected from Greece and the United States to examine consumer attitudes and behavior intentions toward the environmentally responsible practices (ERP) of hotels. Specifically examined is the impact of ERP on consumers' willingness to pay (WTP) for such hotel practices. The results indicate that consumers in both countries were more likely to patronize and demonstrate a strong WTP for hotels that provide ERP. Furthermore, the results reveal that consumers in Greece have higher environmental concerns and WTP than those in the United States, confirming that differences in culture and social structure determine a consumer's Green orientation and WTP.
