Policy-specific synergy levels in GHG and air pollution emission co-control.

Caption

(a-c) Results for the case that climate metrics are represented by CO2e (a), CO2 (b), and BC (c) emission reductions, respectively. The x-axis represents health metric, showing relative changes in deaths associated with on-road emissions attributed to environmental policies, compared to the baseline attributable deaths in 2015. The y-axis represents climate metric, showing relative changes in CO2e emissions attributed to environmental policies, compared to the baseline CO2e emissions from on-road transportation in 2015. Bubbles with dashed borders represent results for 2020, with numerical labels corresponding to the estimated Synergy Index. Values for health metric, climate metric, and the estimated Synergy Index range from 0 to 1, with higher values indicating superior performance.
