U.S. President-Elect Donald Trump’s plans to reduce government regulatory restrictions on industry include some lifting or preventing of regulations on the operations of power plants. This could mean pulling back on new federal power plant regulations intended to cut back on emissions that contribute to global warming and other industries’ practices that contaminate the atmosphere and spread toxic substances. Klaus Lackner, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, and director of ASU’s Center for Negative Carbon Emissions, notes that cleaner and cheaper natural gas is helping to reduce harmful carbon emissions problem but that it remains critical to achieve zero emissions of all greenhouse gasses.
