The agreement is the new international framework to reduce emissions of greenhouse gases. It was adopted by more than 190 countries and territories at the UN climate conference in France last year.

The parameters of the framework say that it takes effect 30 days after more than 55 countries representing more than 55 percent of global emissions have ratified it. The requirements were met on October 5th.

The agreement aims to cut global emissions as quickly as possible and bring them to virtually zero in the latter half of this century.

Unlike the Kyoto Protocol, which mandated only advanced nations reduce emissions, the Paris Agreement covers all nations, including developing countries.

Each nation must submit reduction targets every 5 years and implement measures to achieve them.
The targets are up to each participant. Their commitment will be examined.

Delegates from around the world will gather in Morocco to begin this year's UN climate conference on Monday. They will discuss concrete rules to ensure emission cuts, including ways to verify whether nations have met their goals.

Parties to the Paris agreement will hold their first meeting on the sidelines of the conference. Japan will participate as an observer due to a delay in ratifying the agreement.
