COP26 was the moment countries revisited climate pledges made made under the 2015 Paris Agreement.
Six years ago, countries were asked to make changes to keep global warming "well below" 2C - and to try to aim for 1.5C.
COP stands for "Conference of the Parties", and the one in Glasgow was the 26th annual summit. Ahead of it, 200 countries were asked for their plans to cut emissions by 2030.
The goal is to keep cutting emissions until they reach net zero by mid-century.
