In which one of the following Conferences of Parties (COP) was the Kyoto Protocol adopted?

The Kyoto Protocol was adopted at the third Conference of the Parties, held in Kyoto in 1997.

This meeting set binding emission cuts for developed countries under the climate convention.

The first such conference took place in Berlin in 1995 and only prepared the ground.

The seventh conference at Marrakech settled the operational rules for the protocol later.

The tenth conference came years after the protocol had already been adopted.

The Kyoto Protocol finally entered into force in 2005 after enough ratifications.
