Global responsible intergenerational leadership is introduced by mapping the social representations of intergenerational imbalances in the age of climate change. The multi-faceted investigation of intergenerational equity serves the greater goal to ensure justice as a responsibility for the future. Social representations on intergenerational equity featured notions of ecologic decline related to climate change and unsustainable consumption. Climate change was found to be considered as a major future external influence on humankind. Stakeholder views of intergenerational equity included environmentalism on public officials’ and international organizations’ agendas. Politicians connected intergenerational justice to human rights. Promoting solidarity, ethicality and social responsibility but also innovations and future investment implement intergenerational equity. Long-term solutions may stem from institutional regulation and foresighted taxation but also open debates informing global leaders about complex intertemporal frictions.
