Paris Agreement to take effect in 30 days: UN

The Paris deal has been ratified by 72 countries, accounting for more than 56% of the global greenhouse gas emissions

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.

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

According to the website of the UN Framework Convention on Climate Change (UNFCCC), the Paris deal has been ratified by 72 countries, accounting for more than 56 per cent of the global greenhouse gas emissions.

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

The deal takes effect 30 days after 55 countries, accounting for at least 55 per cent of global emissions, have adopted it.

"The secretary-general is 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.

He added that the UN will announce the names of those Parties that have deposited their ratification instruments by the end of the day.

The much-anticipated Paris Agreement is the third international document on addressing climate change, following the 1992 UNFCCC and the 1997 Kyoto Protocol.
