Portfolio RA16 performed the best across theemission types for most of the CO 2 adder cases. RA2 performed nearly as well, coming in secondplace on SO 2 , NO X , and mercury emissions for all CO 2 adders except the $61 case.Table 7.41 – Total Emissions Footprint by CO 2 Adder Case(From system generation for 2007-2026)Emission Type and UnitsSO 2 NO X Hg CO 2ID 1000 Tons 1000 Tons Pounds 1000 Tons$0 CO 2 Adder CaseRA13 844 1,196 8,325 1,118,625RA14 811 1,157 8,048 1,077,417RA15 814 1,162 8,053 1,079,015RA16 805 1,148 8,035 1,076,347RA17 820 1,170 8,056 1,079,240$8 CO 2 Adder CaseRA13 803 1,132 8,022 1,064,261RA14 766 1,088 7,729 1,019,946RA15 770 1,094 7,735 1,021,983RA16 759 1,077 7,742 1,017,187RA17 777 1,104 7,745 1,023,767$15 CO 2 Adder Case197
