A carbon tax and clean electricity standard (CES) are similar policies in some ways. Both have the potential to drive large emissions reductions from the US power sector and beyond. If the CES is designed to be technology-neutral with tradable credits for clean electricity generation, both policies would operate as market-based mechanisms to encourage such generation.

They also differ in significant ways, and this report, part of the Carbon Tax Research Initiative at Columbia University’s Center on Global Energy Policy, uses energy system modeling to zero in on those differences to enable policy makers to better understand the advantages and drawbacks of each policy tool.
