Governor Ernie Fletcher and his Democratic challenger Steve Beshear outline their plans for environmental policy.
The pair sparred during a midday forum in Louisville.
Beshear says that global warming is a reality and promises to push for more coal production, along with new technology to burn coal more cleanly.
Fletcher also echoed clean-coal technology.
He cited the energy bill that passed during a special legislative session.
The bill allows the state to provide hundreds of millions of dollars in financial incentives to companies that build plants to convert coal to cleaner-burning alternative fuels.
