Representatives of 195 counties reached a historic agreement on Saturday evening that is set to help reduce harmful emissions worldwide.
The deal is the first to commit all countries to cutting carbon emissions.
The agreement is in part legally binding, and partially voluntary.
President of the UN climate conference and French Foreign Minister Laurent Fabius said: “I now invite the COP to adopt the decision entitled Paris Agreement outlined in the document.”
“Looking out to the room I see that the reaction is positive, I see no objections. The Paris agreement is adopted,” he said.
The final draft stipulates limiting greenhouse gas emissions as soon as possible and achieving a balance between sources and sinks of greenhouse gases in the second half of this century.
It also includes maintaining global temperature increases at “well below” 2C (3.6F) and pursuing efforts to limit them to 1.5C, while reviewing progress every five years.
$100bn will be invested every year in climate financing for developing countries by 2020, with a commitment to further finance in the future.
