JPI Climate is a European initiative to coordinate climate research and fund new transnational research initiatives to provide knowledge for climate action. The Czech Republic is one of the countries involved in its Joint Programming Initiative "Connecting Climate Knowledge for Europe". The Joint Transnational Call on "Enabling Societal Transformation in the Face of Climate Change" – SOLSTICE brought seven winning projects of international research consortia. One of them is the JUSTDECARB project - „Socially Just and Politically Robust Decarbonisation: A Knowledge Base and Toolkit for Policymakers“. Centre for Climate Law and Sustainability Studies of the Institute of State and Law CAS is a member of its consortium led by the CICERO Center for International Climate Research (Oslo). The 3-year project brings together social science and humanities researchers from four disciplines (philosophy, political science, economics, and law) across four countries (Austria, Czech Republic, Norway, and UK). The law part of the project that will be addressed by CLASS will primarily focus on human rights and law principles as criteria for assessing climate policies.
