Sulfur dioxide cumulative reductions from a 2008 baseline totaled 1,673,601 tons from all nine RGGI states compared to the ABT Associates estimated impact of RGGI reduction of 109,000 tons so the estimated reduction of RGGI is 6.5 % of the total. (pragmaticenvironmentalistofnewyork.blog)
This would have been good for an 8.6 percent cumulative reduction below sequestration levels, more than recommended by the House Budget Committee (see Figure 1). (aaas.org)
Greenblatt concluded: «Additional policies beyond those in S3 would be needed to continue reduction beyond 2050, but focusing on cumulative reductions may offer a more flexible policy framework.» (newscenter.lbl.gov)
