Kyoto Protocol

The Kyoto Protocol was an international treaty adopted in 1997 that aimed to reduce greenhouse gas emissions based on the scientific consensus that global warming is occurring and human-made CO2 emissions are driving it. The protocol applied to 7 greenhouse gases and was based on the principle of common but differentiated responsibilities, placing the obligation to reduce current emissions on developed countries that are historically responsible for the current levels of greenhouse gases in the atmosphere. The first commitment period started in 2008 and ended in 2012, with 36 countries fully complying, while 9 countries had to resort to flexibility mechanisms. A second commitment period was agreed to in 2012, known as the Doha Amendment, which extended the agreement to 2020, but only 34 of the 37 countries with binding commitments ratified it.learn more on wikipedia
