Earlier this week, Environmental Protection Agency (EPA) Administrator Scott Pruitt confirmed that he will sign a rule to repeal the Clean Power Plan, a signature environmental policy from the Obama administration focused on cutting U.S. carbon emissions. But given the shifting dynamics of the market, this decision might not have the intended impact.

In 2015, the EPA published a final rule to enforce the Clean Power Plan (CPP) to reduce U.S. carbon dioxide emissions from fossil-fuel power plants by 32% by 2030.  The rule set targets based on each state’s unique blend of power generation, allowing states to determine how to most effectively meet the targets.
