A 2013 report from REMI, a consulting firm commissioned by Citizens Climate Lobby, shows that taxing carbon and rebating all of the revenue back to families is a net benefit for the U.S. economy (in each year, economic output is higher than in a scenario without the policy).
The report finds that this "carbon fee and dividend" approach reduces five times as much carbon emissions in 2030 than the Clean Power Plan.
The report also shows that the policy can prevent over 13,000 premature deaths and give the average family of four a $350 monthly check to compensate them for higher energy prices by 2030.
Takeaway: the majority of emissions reductions expected by 2030, relative to 2005, are expected to happen regardless of whether the Clean Power Plan exists.
Relative to the Clean Power Plan's greenhouse gas (GHG) reduction goals for power plants in 2030 (32% below 2005 levels), the U.S. is already two-thirds of the way there (21% below 2005 levels).
Without the Clean Power Plan (CPP), the Department of Energy projects power plant GHG emissions will stay roughly constant, at 20% below 2005 levels in 2030.
Thus, the CPP is the difference between emissions staying constant and declining slightly.
