NOTE: The data presented in this Table are based on international scientific assessments and reflect the latest consensus determinations on potential impacts. However, the reduction requirements and allocations under the Montreal Protocol and many national regulations pursuant to it use older, adopted values. Similarly, emission reporting pursuant to the Kyoto Protocol are based on data from the 1995 IPCC assessment /IPC96/ rather than the updated 2001 assessment /IPC01
