Education is widely acknowledged to be a means for advancing environmental sustainability. Many schools have recently introduced the idea of sustainability into their educational agenda and curriculum. This study uses an innovative method of communicating the principle of sustainability, the "Ecological Footprint" Analysis, which illustrates the impact of community lifestyles upon the natural environment. This paper describes the process of integrating the concept of the ecological footprint at the high school level, analyzes the school's ecological footprint, and discusses its contributions to education for sustainability in schools.
