Federal Environmental Protection Agency officials introduced a proposed rule Monday that would reduce carbon emissions in the U.S. by one-third in the next 16 years. The potential reduction in carbon emissions could vary significantly between states. The initial draft would mandate North Carolina cut carbon emissions 40-percent by 2030. That figure is based on last year's amount of pollution.
North Carolina gets more than half its power from coal. The vast majority of that is produced by Duke Energy - the nation's largest electricity provider.
