Emissions redistribution and environmental justice implications of California’s clean vehicle rebate project
Fig 5
As a result of the clean vehicle rebate project, net local SO2 and NOX emissions decrease more for least disadvantaged communities than for disadvantaged communities, as modeled under the present-day scenario.
Based on the CalEnviroScreen 4.0 indicator, as the level of community disadvantage increases moving to the right, the modeled change in annual (a) SO2 or (b) NOX emissions per census tract increases, moving from more negative to less negative median values. Boxes show the median and extend to the 25th and 75th percentiles; whiskers span 1.5 Interquartile Range (IQR). Notches approximate a 95% confidence interval for the median, extending to ± 1.58 * IQR / sqrt(n). The red horizontal line marks a net local emissions change of zero. Disadvantaged Communities are highlighted in red. Census tracts are grouped into 20 quantile groups based on CalEnviroScreen 4.0 percentile.
