Ireland has formally ratified the Paris Agreement on global climate change, it was announced on Monday.

Minister for Communications Denis Naughten completed the process last Friday, the day the deal came into force.

A spokeswoman for Mr Naughten said Ireland had "deposited the instrument of ratification" with the United Nations last week.

The confirmation came as leaders from almost 200 countries met in Marrakesh, Morocco, for the annual United Nations climate talks.

UN climate chief Patricia Espinosa told delegates "no politician or citizen, no business manager or investor" can doubt that the world is determined to shift towards a "low-emission, resilient society".

The agreement marks the first time all countries have pledged to fight global warming by curbing the rise in greenhouse gas emissions, primarily carbon dioxide from fossil fuels.

Ms Espinosa said: “Achieving the aims and ambitions of the Paris Agreement is not a given. The peaking of global emissions is urgent, as is attaining far more climate-resilient societies.”

Mr Naughten is expected to travel to Morocco next week to participate in the discussions.

Delegates will meet for two weeks to work on the rules for implementing the deal, including how to measure and report emissions so that countries can be held accountable.

The goal of the agreement is to keep the global temperature rise below 2 degrees Celsius compared with pre-industrial times.
