Figure 1. Example of NO_x emissions for baseline and maximum traditional controls scenarios, as well as incrementally more stringent regional NO_x constraints for Region 5, the South Atlantic.

Figure 2. National MACC for NO_x for 2035.

Figure 3. National, sectoral MACCs for NO_x for 2035.

Figure 4. National MACC for NO_x for 2035, as well as MACCs for reductions attributed to traditional controls and RE/EE/FS.

Figure 5. National electric-sector MACC for NO_x for 2035, oriented with marginal cost on the x-axis.

Figure 6. Change in electricity production by fuel in 2035 as a function of marginal cost. Electricity production by fuels or technologies not shown on the graphic (e.g., oil, biomass, nuclear, and hydropower) did not change.

Figure 7. Regional MACCs for NO_x in 2035.

Figure 8. RE/EE/FS portion of regional MACCs in 2035 (percent of NO_x emissions reduced; e.g., the combination of a 40% regional reduction target and 20% reduction from RE/EE/FS would indicate that half the reduction target was met by RE/EE/FS). The markers along each series indicate the last reduction target at which the marginal was less than $60k/tonne.
