Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.
