This chart is based on WRI’s analysis of potential reductions under existing federal authorities and announced state actions through 2030.

The three potential reduction scenarios analyzed include a “Lackluster” scenario that aggregates reductions at the lower end of what is technically feasible and therefore represents low regulatory ambition; a “Middle-of-the-Road” scenario that combines reductions generally in the middle of the range considered technically feasible and corresponding to moderate regulatory ambition; and a “Go-Getter” scenario that adds up reductions that may be considered toward the higher end of what is technically feasible and corresponds to higher regulatory ambition.
