In a world with an ever-increasing population, diminishing natural resources, and greater levels of consumption, sustainability has emerged as a critical concept and it encompasses everything from international policy to lifestyle changes to "green" technologies. While various aspects of sustainability have been adopted by schools and universities, businesses, organizations, and governments, there is a need for more standards-based curricular material that connects directly with sustainability. Geography represents such a natural link, whether it is the three aspects of geo-literacy--interactions, interconnections, and implications--or the direct connection between sustainability and at least four of the National Geography Standards. This binational project between Chile and the United States links sustainability and geography to create 16 standards-based lesson plans that focus on sustainability. The international component is unique, highlighting the significance of sustainability across borders and geographic space, connecting local issues, events, and challenges with the broader global context and with similar occurrences elsewhere in the world. This collaborative project engages scholars in geography education and pre-service social science/geography students at two universities to develop the lesson plans with each lesson plan paired with one from the other country, specifically the state of Iowa in the United States and the region of Coquimbo in Chile. For example, on the topic of renewable energy, there is one lesson plan on challenges to renewable energy in Coquimbo and its counterpart focuses on wind energy resources in Iowa.
