Inherited Futures: Generation Z and Their Parents on the Future and Sustainability

People’s conceptions of the future influence their willingness to engage in sustainability-oriented actions today. A sense of moral responsibility toward both past and future generations may also be linked to greater interest in sustainability. This study explores how members of Generation Z (Gen Z) and their parents conceptualize the future, including their views on intergenerational justice and sustainability. Using semi-structured interviews with 11 Gen Z–parent pairs, we examined how ideas about the future are formed, transmitted, and expressed. Thematic analysis revealed that Gen Z participants most frequently framed the future in terms of economics, technology, and social dynamics, with environmental concerns mentioned occasionally but not as a dominant theme. Compared to their parents, Gen Z expressed distinct priorities—including creating opportunities for future generations—and used different language to describe future possibilities. We develop the concept of the lexicon of futures thinking—the specific terms, metaphors, and conceptual categories used to articulate visions of the future—as a tool for understanding and engaging youth perspectives. These findings offer insights into how educators and advocates can more effectively connect with Gen Z on sustainability issues by aligning with their values and linguistic framing.
