Extended Data Fig. 4: Variations in state-level carbon intensity and mitigation costs to achieve 80% decarbonization nationally.
From: The surprisingly inexpensive cost of state-driven emission control strategies

a, Carbon intensity in 2015; b, Reduction in carbon intensity in 2050 relative to 2015, to achieve 80% national decarbonization with uniform or heterogeneous approach; c, Mitigation cost in 2050 as a fraction of 2050 GDP, to achieve 80% national decarbonization with uniform or heterogeneous approach. All economic values are presented in US$2015.
