The Kyoto Protocol is a treaty that only applies to one country.
A multilateral treaty is concluded among several countries, establishing rights and obligations between each party and every other party
The Protocol was based on the principle of common but differentiated responsibilities: it acknowledged that individual countries have different capabilities in combating climate change, owing to economic development, and therefore placed the obligation to reduce current emissions on developed countries on the basis that they are historically responsible for the current levels of greenhouse gases in the atmosphere
