This chapter critically examines the concept of sustainability, arguing that it has become a hegemonic discourse that perpetuates economic growth while failing to address genuine ecological and social issues. The author, Carlos Escoto Carranza, reflects on his experiences as an environmental lawyer in Mexico, tracing the historical adoption of sustainability from the 1972 “Limits to Growth” report to the Brundtland Report in 1987. He critiques sustainability through a Gramscian lens, suggesting it actually serves economic interests and calls for a re-evaluation of the concept to foster meaningful environmental and social change.
