States Could Slash Clean Power Plan Costs with Mass-Based Standards, Regional Plans -- Study ($)

States could halve the costs of implementing U.S. EPA's Clean Power Plan if they work with other states and use a mass-based standard to cap emissions outright, according to a new study from Duke University's Nicholas Institute for Environmental Policy Solutions. ClimateWire reports that researchers examined three major choices regulators must make as they craft proposals for cutting carbon emissions from power plants to meet their states' individual goals. They looked at the effects of choosing rate-based vs. mass-based standards and regional vs. individual plans, as well as incorporating new natural gas combined-cycle plants into the targets.
