Transnational civil society movements are increasingly at the core of political and social transformations. In 2013, the Panama Papers scandal triggered a global anticorruption campaign, while the recent mobilisation led by Greta Thunberg in defence of the environment has demonstrated how civil society can impact institutions and policies. Many governments are now addressing climate change in their budgetary plans and the Green New Deal is a core policy of the new Von der Leyen’s Commission. Moreover, civil society mobilisation on EU trade agreements (e.g. TTIP) has triggered more transparency on trade issues. The panel discusses how civil society acts, reacts and mobilises. How do institutions and policy-makers respond to transnational mobilisation? The panel will bring together representatives from civil society and from institutions.
