CELESTE HEADLEE, HOST:
It's WEEKENDS on ALL THINGS CONSIDERED from NPR News. I'm Celeste Headlee.
In previous elections, candidates from both parties have pledged to be environmental presidents. This time, neither candidate is talking much about cleaning up the air or protecting scenic lands.
As part of our ongoing series Solve This, which examines how the next president may tackle big problems, NPR's Elizabeth Shogren reports the debate in this election is about whether or how much environmental regulations hurt business, especially the energy industry.
ELIZABETH SHOGREN, BYLINE: America has made progress cleaning up its air and water over recent decades. But dirty air in many areas still contributes to lots of asthma attacks and premature deaths from heart and lung failure. And dirty water in streams across the nation still makes some fish dangerous to eat. President Obama has targeted the pollution that comes from using coal for electricity. One of his new rules for the coal industry fulfills a mandate set by Congress and the first President Bush 22 years ago. Here's President Obama.
PRESIDENT BARACK OBAMA: Because we're acting, emissions of mercury and other pollutants, which cause a range of health problems, including neurological damage in children, will decrease significantly.
SHOGREN: The president's Environmental Protection Agency also started limiting greenhouse gases from new coal-fired power plants. One of the biggest criticisms of Obama's regulations is that they make it harder to get permits to build new projects and create jobs. GOP presidential candidate Mitt Romney says Mr. Obama's regulations are strangling the economic recovery. Here's Romney in Virginia's coal country.
MITT ROMNEY: And the president has made it almost impossible, virtually impossible to build a coal-fired facility in this country. I want to keep using our coal. We get a lot of it. I want to use it.
SHOGREN: Romney has said he'd help businesses by taking a weed whacker to the president's environmental regulations on coal and other industries. Here's what he said this week in Iowa.
ROMNEY: The regulatory burden under this administration has just gone crazy.
SHOGREN: But getting rid of these environmental regulations would not be easy. Jeff Holmstead supports Romney. He headed EPA's air pollution programs under the second President Bush. He knows presidents can't just erase regulations. Holmstead says, first, you have to propose a rule change and give the public time to comment on it. You need to show the scientific and legal justifications.
JEFF HOLMSTEAD: And then you have to build a record that explains why that change makes sense. And I think that that will certainly be done, but it's not something that can be done overnight.
SHOGREN: Even after that, there would be another hurdle. Environmental groups surely would sue if a President Romney tried to weaken environmental protections. That's what they did when the second president Bush's EPA tried to weaken clean air rules. And in many instances, the environmentalists won.
Energy industry consultant Kevin Book says the federal judges who oversee EPA rules likely would prevent big changes.
KEVIN BOOK: If you take a hard right turn on an environmental rule or, for that matter, a hard left turn, you've got strict constructionist judges who are going to say no, and they're on the federal courts today.
SHOGREN: That's because the pollution rules aren't just ideas President Obama and his EPA came up with. They can be decades in the making and ordered by federal courts. They're called for in environmental laws passed by bipartisan majorities in Congress, laws such as the Clean Air Act. It was first signed by President Nixon and strengthened by the first President Bush, both Republicans.
Still, there are ways Romney could move quickly to make things easier for industry, for example, by streamlining permit requirements and easing enforcement. Dan Weiss is a volunteer adviser to the Obama campaign.
DAN WEISS: A President Romney could starve the agencies of money needed to enforce existing public health safeguards - in effect, take the environmental cop off the beat.
SHOGREN: President Obama hasn't spent much time talking up his environmental record. But during his convention speech, he described Romney's attitude this way.
OBAMA: If a company releases toxic pollution into the air your children breathe, well, that's the price of progress.
SHOGREN: The president said he disagrees.
OBAMA: You know what, that's not who we are. That's not what this country is about.
SHOGREN: If Mr. Obama wins a second term, his challenge will be to prove that he can revive the job market while continuing to reduce pollution and promote green energy. Elizabeth Shogren, NPR News, Washington.
