This two-part indicator equally weighs the willingness and promptness of a country in adopting the Kyoto Protocol. Willingness is scored as either 0.5 if a country adopted the Kyoto Protocol by the end of 2005 or 0 if it did not. Promptness is scored on a declining scale that starts at 0.5 and ends at 0. The highest score is given if a country adopted the Kyoto Protocol at its earliest possible ratification in April 1998. The lowest score is given if a country had not ratified the Kyoto Protocol by the end of 2005.
