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.
