In recent decades, interest in the environmental crisis has been growing and the concept of “sustainability” has become the cornerstone and objective of environmental education, stimulating an increase in interest in changing individual behavior. One of the fundamental needs of present-day society consists of establishing educational activities oriented towards sustainability education as a tool to better guarantee a future for future generations. We would like our students to be more aware about our planet's safeguard by using digital tools, collaborating with other students in international classes and improving their motivation to learn English.
