Power dynamics, cultural histories, and institutional biases shape how environmental harms and benefits are distributed across societies. The study of social dimensions, ethics & environmental justice unpacks these inequities, highlighting the disproportionate environmental burdens placed on marginalized and indigenous communities. From air pollution in low-income neighborhoods to land appropriation and climate displacement, environmental injustice is deeply entwined with systemic inequality. Scholars in this field engage with participatory governance, decolonial practices, and ethical frameworks that promote inclusive environmental decision-making. Integrating social science into environmental research ensures that sustainability efforts are equitable, transparent, and culturally responsive. As global transitions accelerate, embedding Social Dimensions, Ethics & Environmental Justice into climate strategies helps ensure no one is left behind and reinforces the human rights foundation of ecological stewardship.
