Last December at the COP 21, the participants voted to adopt a global protocol on climate change. As president of COP 21, France will be the first country to sign at today’s Climate Signing Ceremony at UN headquarters in New York attended by 60 Heads of State and Government. The Paris Agreement will have the biggest opening day for signatures of any global agreement.

The goal of the agreement is to keep the average global temperature rise to less than 2 degrees Celsius above pre-industrial levels.

This morning, President Peña Nieto said on Twitter that "Mexico is a megadiverse country, and we must care for it not only for ourselves, but also for the world and for future generations.”

Parties to the agreement will have the first review of their contributions in 2018 and the first update in 2020. The agreement will enter into force 30 days after at least 55 countries representing 55% of global emissions have ratified it.
