The Kyoto Protocol is an international agreement linked to the United Nations Framework Convention on Climate Change, which commits state parties to reduce greenhouse gas emissions. The Protocol set binding emission reduction targets for 37 industrialized countries and the European community but did not include binding targets for developing countries like China and India. While some parties achieved their targets, overall global emissions continued to rise significantly during the Protocol's first commitment period from 2008-2012. The Protocol has faced criticisms around its flexibility mechanisms, lack of participation from major emitters, and difficulty enforcing compliance. In 2012, an amendment extended the Protocol with a second commitment period through 2020 but with fewer participating parties.
