The Paris Climate Change Agreement, adopted last December, was signed by 175 Parties (174 countries and the European Union) at a ceremony at UN Headquarters. "We are in a race against time.The era of consumption without consequences is over" - U.N. secretary-General Ban Ki-moon told the gathering at the United Nations headquarters in New York.
