This year, Earth Day coincides with the signing ceremony for the Paris Agreement on Climate Change, which will take place at UN Headquarters in New York. The Agreement was adopted by all 196 Parties to the United Nations Framework Convention on Climate Change at COP21 in Paris on 12 December 2015. In the agreement, all countries agreed to work to limit global temperature rise to well below 2 degrees Celsius, and given the grave risks, to strive for 1.5 degrees Celsius. The signing ceremony takes place on the first day that the Agreement will be open for signatures, marking the first step toward ensuring that the Agreement enters into legal force as quickly as possible.
The General Assembly, recognizing that Mother Earth is a common expression for the planet earth in a number of countries and regions, which reflects the interdependence that exists among human beings, other living species and the planet we all inhabit, and noting that Earth Day is observed each year in many countries, decided to designate 22 April as International Mother Earth Day in 2009, with resolution A/RES/63/278.
