This chapter offers a critical examination of the intersecting terrain of climate and mobility justice. Drawing from justice theories and the new mobilities paradigm, it contends that while climate change is often narrated as a universal challenge, its impacts are unevenly distributed, reflecting and reinforcing entrenched global and local inequalities. The chapter dissects how climate-induced disruptions amplify existing social, economic, and political vulnerabilities, disproportionately affecting historically marginalized communities, Indigenous peoples, and those least responsible for ecological degradation. It critiques dominant policy frameworks—both national and international—that emphasize technocratic, market-driven solutions while neglecting the structural roots of injustice. Simultaneously, it interrogates the uneven geographies of mobility, revealing how state-centric border regimes, visa policies, and migration controls reproduce global hierarchies of race, class, and citizenship. By integrating multiple dimensions of justice—national, international, intergenerational, and cosmovisional—the chapter advances a call for a unified, justice-centered approach that challenges epistemic and institutional boundaries between climate and migration governance. Ultimately, it calls for a multi-scalar, intersectional, and more-than-human framework to rethink justice in an era defined by ecological precarity and unequal mobility.
