Most major events scheduled for 2020 that were postponed due to the pandemic were hosted in 2021, including the Eurovision Song Contest, the 26th United Nations Climate Change Conference, Expo 2020, and sporting events such as UEFA Euro 2020, the 2020 Summer Olympics and Paralympics, as well as the 2021 Copa América.
