Since the 2002 Assessment of the Technology and Economic Assessment Panel (TEAP), a large number of technical developments have taken place. The direction many of these developments have taken could not have been predicted in 2002. The Panel's Technical Options Committees, on Chemicals (CTOC), on Foams (FTOC), on Halons (HTOC), on Methyl Bromide (MBTOC), on Medical Uses (MTOC) and on Refrigeration and AC (RTOC) have each issued a 2006 Assessment Report that document these developments. The Executive Summaries of these reports form the body of the 2006 TEAP Assessment Report and their Abstract Executive Summaries, with the summaries of other chapters, form the Executive Summary of the 2006 TEAP Assessment Report."

“Even if the control measures of the Montreal Protocol were to be implemented by all nations, today’s atmospheric abundance of chlorine (about 3 parts per billion by volume (ppbv) will at least double to triple during the next century. If the atmospheric abundance of chlorine reaches 9 ppbv by about 2050, ozone depletion of 0–4 percent in the tropics and 4–12 percent at high latitudes would be predicted, even without including the effects of heterogeneous chemical processes known to occur in polar regions, which may further increase the magnitude of the predicted ozone depletion.”
