This two-part indicator equally weighs the willingness and promptness of a country in adopting the United Nations Framework Convention on Climate Change (UNFCCC). Willingness is scored as either 0.5 if a country adopted the UNFCCC 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 the country adopted the UNFCCC at its earliest possible ratification date in July 1992. The lowest score is given if a country had not ratified the UNFCC at the time of the Kyoto Conference in December 1997.
