Current measures can deliver reductions of 25% below 2005 levels by 2030; enhanced non-federal action can deliver up to 37% reductions, and a comprehensive strategy that layers ambitious federal action on top of state and other sub-national action can deliver up to 49% below 2005 levels by 2030. The gray line shows historical emissions drawn from EPA data. Given large uncertainties and limitations in connecting individual country emissions to global temperature pathways, the shading in the 2 and 1.5 °C bars on the right is indicative.
