The G20 (or Group of Twenty) is an intergovernmental forum comprising 19 countries and the European Union (EU). It works to address major issues related to the global economy, such as international financial stability, climate change mitigation, and sustainable development.[3]

The G20 is composed of most of the world's largest economies, including both industrialized and developing nations. The group collectively accounts for around 90 percent of gross world product (GWP),[4] 75-80 percent of international trade,[A 1] two-thirds of the world's population,[2] and roughly half the world's land area.

The G20 was founded in 1999 in response to several world economic crises. Since 2008, the group convenes at least once a year, with summits involving each member's head of government or state, finance minister, foreign minister, and other high-ranking officials; the EU is represented by the European Commission and the European Central Bank.[5][6][B 1] Other countries, international organizations, and nongovernmental organizations are invited to attend the summits, some on a permanent basis.

At its 2009 summit, the G20 declared itself the primary venue for international economic and financial cooperation.[7] The group's stature has risen during the subsequent decade, and it is recognized by analysts as exercising considerable global influence;[8] it is also criticized for its limited membership,[9] lack of enforcement powers,[10] and its alleged undermining of existing international institutions.[9] Summits are often met with protests, particularly by anti-globalization groups.[11][12]
