Council of Nuclear Matters, an industry-backed group that advocates for nuclear power as a means to combat climate change. In that role, she said, "We can't take a carbon-free source of energy off the table." She has acknowledged that looking at herself twenty years earlier, she would "probably not be pro-nuclear", but said, "I think climate change is the biggest problem the world has ever faced" and it would simply be "irresponsible" not to consider nuclear energy as part of the solution. After a different administration had been in power for a year, Browner was one of several former EPA heads who expressed alarm at the effects that new head Scott Pruitt had had upon the agency.
