Addressing climate change requires rapid and just systems transformations at unprecedented scales. The seminar will provide an overview of the scientific and political discussions pertaining to climate justice. Through interactive sessions students will learn about the main approaches to generate climate scenarios and critically reflect upon existing narratives that underpin them. We will illustrate both climate risks and climate opportunities and assess the impact of major climate policies, such as the US Inflation Reduction Act. Emphasis will be given also to the potential of demand-side mitigation and the role of cities and digitalisation for accelerating clean technology diffusion, increase innovation, and democratise the access to basic services.
