In May 2013, 191 countries and a regional economic organization (EC) ratified the agreement, accounting for more than 61.6% of 1990 emissions from Annex I countries.

Sanctions may be unilateral, imposed by a single country on another country or multilateral imposed by one or more countries on a number of different countries.
