A study of the role of business and sustainability in Portugal. The country is a small, open, export-oriented economy whose best-known industries have been shaped by centuries of trade, family enterprise, and geography. Through four pre-trip seminars and a two-week field experience, students analyze the industries that define Portuguese commerce (cork, wine, maritime operations, tourism, and tile), examine how national culture shapes business practice, and evaluate the sustainability claims and trade-offs of heritage and emerging sectors.
