NORTH CAROLINA -- The Tar Heel State is one of 22 states suing the Environmental Protection Agency.

• The coalition of states wants to block the Trump administration's rollback of an Obama-era climate rule
• The rule change is part of President Trump's campaign promise to revive the nation's coal industry
• It eliminates an aggressive effort to reduce the energy sector's carbon footprint

The coalition of states wants to block the Trump administration's rollback of an Obama-era climate rule.

The states claim the EPA's efforts to roll back restrictions on coal-burning power plants undercuts their efforts to reduce greenhouse gas emissions.

The rule change is part of President Trump's campaign promise to revive the nation's coal industry.

It eliminates an aggressive effort to reduce the energy sector's carbon footprint.

The EPA is defending the revised rule and says it believes the courts will uphold the roll back.

In a statement, North Carolina Attorney General Josh Stein said "The Trump administration's replacement rule does nothing to address this crisis or protect us and it violates the clean air act in the process. The dirty power rule is exactly the wrong policy at exactly the wrong time."
