The global environmental crisis demands urgent attention and comprehensive action. While governments must prioritise environmental protection and climate change mitigation, the continued depletion of natural resources calls for innovative approaches. One such approach is the Environmental Global Citizenship theory, which offers a perspective on participatory environmental governance while emphasising cultural diversity. The article argues that the idea of global environmental citizenship can help address the challenges associated to the global environmental crisis, outlining a vast theoretical framework to this notion, grounded in a thorough literature review and legal examination of global environmental agreements. Environmental Global Citizenship is presented as a critical, yet non-exclusive strategy for global environmental stewardship, simultaneously advocating for a model of global integration that is rooted in cultural diversity. The manuscript underscores that the concept of Environmental Global Citizenship should form one necessary aspect of a more extensive environmental protection global strategy.
