Addressing climate change requires rapid and just systemic transformations at an unprecedented scale. 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 the demand-side mitigation and the role of cities and digitalisation in accelerating clean technology diffusion, increasing innovation, and democratising the access to basic services.
