Short summary
We studied the impact of US air quality (AQ) regulations and hypothetical CO2 reduction policy on public health and climate change. We find that AQ regulations are projected to have strong health benefits in the near future but result in a positive radiative forcing (RF), ~ 0.8 W m−2, over the USA. Under the US CO2 policy we find air quality co-benefits. However, despite CO2 reductions, it leads to overall positive RF (+0.22 W m−2 in 2055) over the USA mainly by lowering SO2 via less coal usage.
