ABSTRACT
The G20 has substantial and growing legitimacy, grounded in its high inherent and constitutional legitimacy arising from the core characteristics of its composition, which well match the needs of the globalized 21st-century world. The G20's growing input, throughput and output legitimacy are seen in its increasing performance on the relevant dimensions of governance through to its Osaka Summit in June 2019, the results of its innovative emergency virtual summit on March 26, 2020, and the promising prospects for its Riyadh Summit hosted by Saudi Arabia in November 2020. Yet there remains a need to strengthen G20 legitimacy, through several low-cost reforms under G20 leaders’ direct control, especially on the current great threat to people's health and the existential challenge of climate change.
