Climate change is a crucial challenge for both intragenerational and intergenerational equity, offering the world an unprecedented opportunity to demonstrate its commitment to the principles and practice of sustainable development. In 2016, through Transforming Our World: The 2030 Agenda for Sustainable Development, the UN and its member States agreed on seventeen SDGs for the world, identifying time-bound targets and implementation methods. As legal reviews have revealed, the targets adopted in the SDGs are not just aspirational goals and objectives, as many can also be found in the object and purpose of many important international treaties among states. Achieving SDG 13 to take urgent action to combat climate change and its impacts will be implemented in part through the 2015 Paris Agreement. Indeed, in SDG 13, States acknowledge that the 1992 UNFCCC and its instruments are the primary international, intergovernmental forum for negotiating the global response to climate change. Other SDGs, for instance on energy, water, hunger, poverty, biodiversity, oceans, cities, and infrastructure, are also highly relevant to climate change, including SDG 10 to reduce inequality within and among countries and, as such, offer crucial opportunities to either frustrate or foster intergenerational equity and justice.
