There is an on-going scholarly debate on European (dis)integration. Research (Cross, 2017; Jones et al., 2021; Vollard, 2018; Webber, 2018) has addressed how historical European crises often led to deepened European collaboration (Cross, 2017). The scholarly work has mentioned how severe crises in EU member states' reluctance to stay as member-state or include new member-states, obstruction to integration in certain policy areas (the Euro, CFSP, SEM and Schengen), right-winged populism and anti-EU rhetoric in most cases not resulted in expected disintegration, but rather in new negotiations and policy-making. In such context, the European Commission plays an important role to promote European interest beyond individual member-states' national interests. The climate change challenge provides one of the most contemporary global crisis. The Agenda 2050 on sustainable development is a bold and ambitious vision by the European Commission for a climate neutral Europe and may serve as a normative model globally. This study explores the recent role of the European Commission to promote sustainable development. It is argued that in times of serious European crises, the European Commission has acted as a normative power and transformed crises into a window of opportunity.
