The Paris Agreement on climate change was signed by the largest number of countries ever in one day.

When 174 world leaders signed the Paris Agreement on Earth Day in 2016 at the United Nations (UN) headquarters in New York, it was the largest number of countries ever to come together to sign anything on a single day, according to the UN. The agreement aimed to combat climate change and accelerate and intensify the actions and investments needed to strengthen the global climate effort.
