The increasing consciousness of the climate emergency is resulting in an impressive rise in climate litigation both at the national and international level, pushing all stakeholders involved to think about more ambitious rules. This panel aims to address the challenges and opportunities faced by ICTs in order to clarify climate change obligations incumbent upon States and non-state actors. In this logic, various questions may be raised such as: the contribution to international law relevant to climate change of the pending requests for advisory opinions from the ICJ, ITLOS and IACtHR; the influence of politics in advisory proceedings, taking into account the TWAIL perspective; the participation of States and NSAs in climate change litigation before ICTs; the limits and possibilities of cross-fertilization between ICTs? decisions; and the impact of ICTs? advisory opinions on climate change litigation at the regional and domestic levels.
