In which year was the Kyoto Protocol adopted?

Correct answer: 1997

The Kyoto Protocol was adopted on 11 December 1997 in Kyoto, Japan, under the UNFCCC. It set greenhouse-gas emission reduction targets for developed countries. 2005 is a close distractor because that was the year the Protocol entered into force, not the year it was adopted. Exam tip: remember “adopted in 1997; entered into force in 2005.”
