UNITED NATIONS, Oct. 5 (Xinhua) -- The Paris Agreement on climate change is expected to enter into force in 30 days after it crossed "the second and final threshold" needed for it to take effect, the United Nations announced on Wednesday.

"Today, we expect the Paris Agreement on climate change to have crossed the second and final threshold needed for it to enter into force," Farhan Haq, the deputy UN spokesman, said at a daily news briefing here.

The Paris deal has been so far ratified by 72 countries accounting for more than 56 percent of the global greengas emissions, said the website of the United Nations Framework Convention on Climate Change (UNFCCC).

"On October 5, 2016, the threshold for entry into force of the Paris Agreement has been achieved," the UN website said.

The Paris Agreement, adopted in December 2015, shall enter into force on the 30th day after the date on which at least 55 Parties to the Convention accounting in total for at least an estimated 55 percent of the total global greenhouse gas emissions have deposited their instruments of ratification, acceptance, approval or accession with the Depositary.

"The secretary-general has been very encouraged by the tremendous positive support from a broad coalition of countries -- from the largest emitters to the small island developing states -- to bring the Paris Agreement to life as soon as possible," Haq said.

"We will announce the names of those Parties that have deposited their ratification instruments by the end of the day," he said. "The UN recognizes that all Parties that deposit in a single day are considered collectively in meeting the legal threshold."

"The secretary-general expresses his appreciation for all countries that have accelerated their domestic processes to ensure the Paris Agreement comes to life as soon as possible this year," he said.

The much-anticipated Paris Agreement is the third international document on addressing climate change, following the 1992 United Nations Framework Convention on Climate Change and the 1997 Kyoto Protocol.
