Global citizenship education (GCED) is a form of civic learning that involves students' active participation in projects that address global issues of a social, political, economic, or environmental nature. The two main elements of GCE are 'global consciousness'; the moral or ethical aspect of global issues, and 'global competencies', or skills meant to enable learners to participate in changing and developing the world. The promotion of GCE was a response by governments and NGOs to the emergence of supranational institution, regional economic blocs, and the development of information and communications technologies. These have all resulted in the emergence of a more globally oriented and collaborative approach to education. GCE addresses themes such as peace and human rights, intercultural understanding, citizenship education, respect for diversity and tolerance, and inclusiveness.

GCE provides the overall lens which views the role of education in the promotion of the rule of law (RoL). It draws upon experience from other education processes, including human rights education, peace education, education for sustainable development, education for international and intercultural understanding. GCE aims to empower learners to engage and assume active roles, both locally and globally, as proactive contributors to a more just, peaceful, tolerant, inclusive, secure and sustainable world. GCE aspires to be a transformative experience, to give learners the opportunities and competencies to realize their rights and obligations to promote a better world and future. GCE is built on a lifelong learning perspective. It is not only for children and youth but also for adults. It can be delivered in formal, non-formal and informal settings. For this reason, GCE is part and parcel of the Sustainable Development Goal 4 on Education (SDG4, Target 4.7). GCE is also a component of the single indicator for Target 12.8 in Sustainable Development Goal 12 for "responsible consumption and production".

The Global Citizenship Foundation defines Global citizenship education as "a transformative, lifelong pursuit that involves both curricular learning and practical experience to shape a mindset to care for humanity and the planet, and to equip individuals with global competence to undertake responsible actions aimed at forging more just, peaceful, secure, sustainable, tolerant and inclusive societies."

Global citizenship consists of voluntary practices oriented to human rights, social justice, and environmentalism at the local, regional, and global level. Unlike national citizenship, global citizenship does not denote any legal status or allegiance to an actual form of government. The emergence of regional economic blocs, supra-national political institutions such as the European Union, and the advancement of ICTs, has caused governments to try to prepare national populations to be competitive in the global jobs market. This has led to the introduction of global citizenship education programs at primary, secondary, and tertiary level, but also at independent NGOs, grass roots organizations, and other large scale educational organizations, such as the International Baccalaureate Organization and UNESCO.

The most important features of global citizenship education are voluntary action that can extend from local to international collectives; the practice of cultural empathy; and a focus on active participation in social and political life at the local and global level. In the late 1990s, OXFAM UK designed a curriculum for global citizenship education which stressed "the 'active' role of global citizens".In this approach, individuals and groups both inside and outside the educational sector might take action that addresses human rights, trade, poverty, health, and environmental issues, for example. This is sometimes called the 'global consciousness' aspect of GCE. However, organizations such as UNESCO have also begun to emphasize 'global competencies', including science and technology into their GCE curricula.

In the present era of globalization, the recognition of global interdependence on the part of the general public has led to a higher degree of interest in global citizenship in education. Though modern schooling may have been oriented to education suitable for the nation-state throughout the 19th and 20th centuries, in the 21st century, citizenship is understood in global terms, so that schooling might improve individual nations' global competitiveness. Many universities worldwide have responded to the need for a globally oriented education by sending their students to study abroad in increasing numbers, and some have announced that this will soon become a mandatory degree requirement.

Many governments also now promote GCE for the cohesion of society. The large numbers of people migrating across national borders means that the diversity of ethnic, religious, and linguistic groups, "has raised [...] complex and difficult questions about citizenship, human rights, democracy, and education". In addition, global issues related to sustainability, such as the world's future energy arrangements, have also been incorporated into the domain of global citizenship education.

While GCE can take different forms, it has some common elements, which include fostering in learners the following competences:
