Ep 43: EPA's Miles Per Gallon Decision Anything But Simple

The EPA says it's going to revise the federal fuel efficiency standards for cars and trucks, which environmentalists fear could resurrect the gas guzzlers that used to roam the roads decades ago. For this episode of Parts Per Billion, we give the keys to climate reporter Abby Smith, who tries to explain a very complicated and messy regulatory situation. For one, she says, there's the issue of California, which has the power to set its own efficiency standards for cars and is likely not on...


Ep 42: Anyone Want to Buy a Superfund Site?

Sometimes businesses leave toxic waste in their wake when they shut down a factory. What should be done with that contaminated land? That's where the EPA's Superfund program comes in. Its mission is to clean up the land and makes it usable for someone else. But who really wants to buy a Superfund site? For the latest of Parts Per Billion, Bloomberg Environment reporter Sylvia Carignan talks about the agency's efforts to make these rehabilitated properties more attractive to potential...


Ep 41: Back to Nature in the Big City

Hey big city dwellers, ever wish you could escape the stress of the concrete jungle and visit something that more resembles an actual jungle? Well now, thanks to something called the "biophilic" movement, your wish may be coming true. On this episode of Parts Per Billion, we head over to Kingman Island--a nature preserve nestled in the heart of Washington's inner city--to learn more about this movement from Bloomberg Environment reporter Adam Allington.


Ep 40: Pot and Poison on Illegal Weed Farms

Marijuana is becoming a big business and many are hoping this will eventually drive out the illegal pot farmers and their environmental reckless pest control tactics. However, not everyone is so sure. Legal pot could just create a larger market for the drug, which in turn could make it more lucrative to grow the crop illegally. On this episode of Bloomberg Environment's podcast Parts Per Billion, we speak with reporter Sara Merken about the environmental hazards of growing marijuana and...


Ep 39: New Year, New Environment?

Welcome to 2018! For the latest episode of our podcast, Parts Per Billion, we convene a roundtable discussion among Bloomberg Environment reporters of some of the big policy issues that will be shaping the news in this new year. We touch on everything from energy to chemicals to, of course, climate change. (Note: Due to recording problems, some of the audio in this week's episode is distorted. We apologize for the audio quality.)


Ep 36: Will Corporations Save Us From Climate Change?

It's pretty clear that the federal government is now out of the business of leading the way on climate change. Can America's CEO's fill this leadership vacuum? We speak with Dean Scott about what companies are doing to become more sustainable and whether you really can "do well by doing good."


Ep 35: Celebrate SCOTUS Day With Parts Per Billion

For attorneys, today is like Christmas, July 4th and Super Bowl Sunday all rolled into one. It's the first day of the Supreme Court's new term! To get you prepared for what to expect, we spoke with John Cruden, who was the top environmental attorney in the Obama Department of Justice. Cruden talks with us about the environmental cases (or lack thereof) that the court has agreed to hear and also about how changes among the nine justices could affect the shape of their rulings.


Ep 34: After Hurricane, Houston Can't Be What It Was

In some ways, things are returning to normal in Houston after Hurricane Harvey. But in other, very important ways, things will never be back to normal there. We speak with Bloomberg BNA Houston correspondent Nushin Huq, a lifelong resident of the city, about how the cleanup is going a month after the storm and about some of the long-term environmental problems that may trouble Houston for years to come.


Ep 33: The Frenzy Begins as Congress Returns

Congress returns from a month-long vacation today and it definitely has its work cut out for it: by the end of this month, it has to fund the government, raise the debt ceiling, reauthorize the FAA and provide disaster relief for victims of Hurricane Harvey. We speak with Bloomberg BNA's Dean Scott and Brian Dabbs about all the environmental measures that might get tacked on to these "must pass" bills.


Ep 32: Finger Pointing on the Farm Amid Weed Killer Calamity

No one's sure who's to blame for the widespread crop damage that was caused by a new weed killer from Monsanto and BASF. Farmers blame the chemical companies, while the chemical companies blame state regulators, and so on and so on. In this episode, we speak with Bloomberg BNA's Tiffany Stecker, who just returned from a visit to the hardest hit area, to sort out what happened here.


Ep 30: Trump a Headache for Pollution Plagued Border Town Mayor

On this episode of Parts Per Billion, we speak with the mayor of a California border town who's struggling with an international pollution problem. After big rain storms, raw sewage can seep into a river in Mexico that flows across the border into his town. Though the mayor is frustrated with his neighbors to the south, he says Donald Trump's harsh rhetoric is making all of these issues harder to solve.


Ep 29: What Happens When Empty Desks Run the Government

President Donald Trump blamed Democrats June 5 for “taking forever” to approve his administration’s appointees in a tweet, say that “They are nothing but OBSTRUCTIONISTS!” But, Trump hasn't moved the quickest of the last few presidents on vetting and getting appointees through the confirmation process—in fact, he is the slowest of the last four presidents, according to data collected by the Partnership for Public Service. Of the 559 key positions requiring Senate confirmation, Trump has...


Ep 28: The World Reacts to Trump's Paris Withdrawal

On this breaking news episode of Parts Per Billion, we speak with international climate reporter Eric J. Lyman about how the major global powers will react to President Trump's decision earlier today to withdraw the U.S. from the Paris climate agreement.


Ep 25: Why Is Water So Cheap? (Hint: It’s Not)

This week on our environmental policy podcast Parts Per Billion we begin the first in a series on drinking water—specifically, how do we pay for the drinking water infrastructure upgrades the country badly needs? We pose that question to Rep. Paul Tonko (D-N.Y.), the top Democrat on a key environmental subcommittee in the House. He says without a big infusion of federal cash, incidents like the ongoing contamination crisis in Flint, Mich., could become commonplace.


Celebrating the Holidays with Chemicals

This week, we're taking a holiday look back at one of our favorite episodes from earlier this year on the implications of the new chemicals law. What will the law mean for big companies, small companies and for you and me?


Ep 18: International Climate Talks and Trump’s Ghost

Even though he wasn't president yet, Donald Trump had a huge impact on the international climate change talks in Morocco a few weeks ago. Bloomberg BNA climate reporter Dean Scott talks about how The Donald influenced the outcome of the talks and where global climate negotiations are headed next.


Ep 17: Making Abandoned Mines Usable Again

How do you make an abandoned coal mine into something that stimulates a local economy, like a park or a farm, instead of literally just an empty hole in the ground? Mine reclamation may be the answer. And there’s a $1 billion bill in Congress right now that could kick start a wave of reclamation across the economically devastated towns in Appalachia. But there’s a catch: can the bill make it through the House and the Senate with only days left to go before the end of this lame-duck session...


Ep 13: Great Barrier Reef's Problems Both Global and Local

Both climate change and water pollution have made 2016 one of the worst years ever for the Great Barrier Reef. We speak with Bloomberg BNA Australia correspondent Murray Griffin about the economic and political obstacles making it difficult for Australia to stop the damage and fix what's been broken.


Ep 11: Climate Change in a Democratic Senate

It's looking like the Democrats have a pretty good shot at taking back the Senate this fall. If they do, how will they tackle climate change? Do they all agree on what strategies they should pursue? (Spoiler alert: they don't) This is the latest in our series "In the Year 2017" that examines how a new administration and a new Congress will handle environmental issues next year and beyond.


Ep 10: Flint, the Environment and Civil Rights

What's wrong with the EPA's Office of Civil Rights? What's it doing to reform itself? And could it have prevented the Flint water crisis? We speak with Rachel Leven, Bloomberg BNA's environmental justice reporter, about problems at the EPA's civil rights watchdog and about who has been held accountable for Flint... at least, so far.
