Washington's emissions vs. a straight-line path to the 2030 limit

Washington emitted 96.1 million metric tons of greenhouse gases in 2022. A straight line from the 2020 limit to the 2030 limit would have put 2022 at 84.7, so emissions were 13.4% above that path. Reaching 51.2 by 2030 means cutting about 5.6 million metric tons a year from 2023 on.
