Table 2. Assessed NCS pathways listed in descending order by their respective Ambitious potential CO2e reductions in the final year (ca. 2050) of a 30-year deployment for Washington state.

Reductions are shown here as the median of 1,000 Monte Carlo simulations along with the minimum and maximum ends of confidence intervals ranging from 5th to 95th percentiles.

Notes.

^aCombination of five activities: harvests on Private, State, Federal, and Other land owner types, and additional sequestration occurring where even-aged management would otherwise likely take place on Private timberlands.

^bCombination of three activities: cover crops, no-till, and nutrient management on croplands.

^cCombination of two activities: avoided conversion from forest-to-rural and forest-to-urban development.

^dMedian and confidence intervals of all pathways combined (called Total here) were calculated from all pathways simultaneously and not by summing the median and confidence interval results of each pathway listed in this table.
