By 1992 the list of participating countries had grown to 140, and the timetable for ending production of CFCs advanced to 1996. This goal has largely been met. HCFCs pose less of a risk than CFCs because they decompose more readily in the lower atmosphere; nevertheless, they too degrade the ozone layer and are scheduled to be phased out by 2030.
From the end of 1984 until the eve of the Great Recession at the end of 2007, real personal consumption grew almost 37% more than the other components of real GDP. To a large extent, the secular growth of demand depended on the reliable rise in the spending of American households.
At its meeting, the committee determined that a trough in business activity occurred in the U.S. economy in June 2009. The trough marks the end of the recession that began in December 2007 and the beginning of an expansion. The recession lasted 18 months, which makes it the longest of any recession since World War II. Previously the longest postwar recessions were those of 1973-75 and 1981-82, both of which lasted 16 months. In determining that a trough occurred in June 2009, the committee did not conclude that economic conditions since that month have been favorable or that the economy has returned to operating at normal capacity.
