A career State Department official speaking at a conference Thursday on behalf of the Trump administration backed a climate policy then-President Obama pursued shortly before he left office.

The policy phases down powerful greenhouse gases found in a range of everyday appliances. This is the most explicit and public the Trump administration has been about supporting it.

The big picture: The conference, held this week in Montreal, is about a recent amendment to the Montreal Protocol, a global treaty created 30 years ago to fix the hole in the Earth's ozone layer, which is now it's achieving its goal. World leaders, led by the Obama administration, agreed in October 2016 to the Kigali amendment, which would phase down emissions of powerful greenhouse gases in refrigerants called hydrofluorocarbons (HFCs). HFCs are used in many appliances from air conditioners to refrigerators.

Quoted: "The United States believes the Kigali Amendment represents a pragmatic and balanced approach to phasing down the production and consumption of HFCs, and therefore we support the goals and approach of the Amendment," said Judith Garber, Principal Deputy Assistant Secretary of the State Department's Bureau of Oceans and International Environmental and Scientific Affairs.

What's next: Rhetorical backing for the amendment is one thing, but to have it actually take effect, the administration needs to send it over to the Senate so it can vote on its official ratification, as the Senate has done on other amendments and the original treaty 30 years ago. "There is no timeline currently determined for these steps, but we have initiated the process to consider U.S. ratification of the Amendment," Garber said.

Fast facts: The Montreal Protocol is a treaty about the ozone layer, but this latest amendment from Kigali represents an evolution to concerns about climate change. The 2015 Paris climate deal, which is a non-binding treaty that didn't require congressional input, is mostly about cutting other greenhouse gases from energy and land use. It's wholly separate from the Montreal Protocol.

Bottom line: Process matters a lot here. One of the biggest complaints of Trump administration officials about the Paris deal is that Obama circumvented Congress (because he knew he wouldn't get support from the GOP-controlled Senate). The Kigali amendment backers, which include chemical makers like Honeywell and Chemours, are emphasizing how this is a collaborative process with Congress and is about the Montreal Protocol, not climate change per se.

What we're hearing: "These remarks in support of the Kigali Amendment are very significant. Obviously, they were cleared by the White House," said David Doniger, who directs the climate change program at the Natural Resources Defense Council, by email. "The contrast with Trump's rejection of Paris is striking. But the Montreal Protocol and all of its amendments have enjoyed support from presidents and members of Congress from both parties."

My thought bubble:

If/when you see this process unfold further, don't expect congressional Republicans and administration officials, most of whom don't acknowledge climate change is a problem, to focus on the climate angle. It'll be all about collaboration and protecting the environment and creating business opportunities for industry.

  • The amendment is set to go into force (for those that have officially signed onto it) in January 2019, thanks to Sweden just recently signing on and meeting the ratification threshold, per the NYT.

Sen. Tim Scott (R-S.C.) told reporters on Wednesday that he believes President Trump "misspoke" when he told the far-right "Proud Boys" group to "stand back and stand by" in response to a question about condemning white supremacy at the first presidential debate.

Catch up quick: Moderator Chris Wallace asked Trump on Tuesday, "Are you willing, tonight, to condemn white supremacists and militia groups and to say that they need to stand down?" Trump asked who specifically he should condemn, and then responded, "Proud Boys, stand back and stand by. But I'll tell you what, somebody's got to do something about antifa and the left."

The Commission on Presidential Debates announced Wednesday that it plans to implement changes to rules for the remaining debates, after Tuesday night's head-to-head between Joe Biden and Donald Trump was practically incoherent for most of the night.

What they are saying: "Last night's debate made clear that additional structure should be added to the format of the remaining debates to ensure a more orderly discussion of the issues," the CPD said in a statement.

Trump says he doesn't know who Proud Boys are after telling them to "stand by"

President Trump told reporters on Wednesday that he doesn't know who the "Proud Boys" are, after saying at the presidential debate last night that the far-right group should "stand back and stand by" in response to a question asking him to condemn white supremacists.

Why it matters: The comments set off outrage and calls for clarification from a number of Republican senators. After being asked several times on Wednesday whether he will condemn white supremacy, Trump responded: "I have always denounced any form — any form of any of that, you have to denounce. But I also — Joe Biden has to say something about antifa."
