A new proposal by the Environmental Protection Agency to reduce carbon emissions is "modest" and won't negatively affect the consumer, Public Citizen's Tyson Slocum told CNBC.
According to the EPA's new regulations, U.S. power plants must cut carbon emissions 30 percent by 2030 from 2005 levels. Each state will create its own plan.
"This plan is not about raising prices, the goals are too modest and the states have too much flexibility," Slocum said in an interview with "Street Signs."
"The rules give so much flexibility to electric utilities and states to come up with plans, including energy efficiency, renewable energy deployment [and] investments in the grid, to offset coal emissions."
