The European Parliament has approved the ratification of the Paris Agreement, meaning the necessary threshold has been reached, and the agreement will enter into force on 4 November.
US president Barack Obama, whose administration helped negotiate the agreement, said the world had arrived at a “historic moment”. Seventy-three of 197 parties to the convention have ratified the Paris Agreement, including the US and China, the two biggest greenhouse gas emitters.
The deal doesn’t legally require countries to curb emissions or take other steps on climate change, but it does require them to release targets and report emissions.
Presidential nominee Donald Trump has said he would “cancel” the agreement.
But once the deal goes into force, a country must wait three years to announce it intends to pull out, and then wait another year to actually do so.
