State Department Climate Move Hits Snag at White House

The U.S. State Department's effort to combat a class of "super greenhouse gases" many thousands of times more potent than CO2 hit a speed bump at the White House yesterday, jeopardizing its chances of meeting a May 4 deadline.

The goal of the effort is to use the Montreal Protocol to phase down the global use of hydroflurocarbons, or HFCs. While currently used only in small amounts for air-conditioning and refrigeration, these gases are projected to grow astronomically in coming decades.

In response to the White House delay, Sens. John Kerry and Barbara Boxer sent a letter to President Obama today urging him to get behind the State Department plan.

"We understand that your administration is considering offering an amendment to the Montreal Protocol next week that would provide authority to regulate HFCs. We strongly support such an amendment," they wrote.

Reps. Henry Waxman and Ed Markey, leading the push for climate legislation in the House, also supported the State Department plan in a letter sent earlier this month to the White House.

Left unchecked, HFCs would add up to 25 times the current total U.S. emissions to the global burden by 2040, largely because of their use in ever greater numbers in the developing world. They could effectively negate all reductions in CO2 currently being contemplated.

Over the 20 years of its existence, the Montreal Protocol on Substances that Deplete the Ozone Layer has tackled the phase out of more than 90 similar gases, and policymakers believe it offers the best avenue for immediately handling HFCs.

Earlier this month in Bonn, Todd Stern, the United States' chief climate negotiator, described the Montreal Protocol as "the most successful environmental treaty that we have," and he listed it first among five building blocks for a successful international climate treaty to be negotiated in Copenhagen at the end of this year.

The State Department, EPA, the White House Council on Environmental Quality and the Pentagon are among the agencies behind the plan to amend the Montreal Protocol so it can regulate HFCs, and expectations for success were high going in to an interagency meeting at the White House yesterday.

But the plan hit stiff resistance from a White House economist who attended the meeting, three sources closely involved in the process tell SolveClimate.

The economist argued that HFCs were needed within a CO2 cap-and-trade system and should not be shifted to the Montreal Protocol.

Maintaining their inclusion within the Kyoto basket of gases would help keep the price of carbon credits down, the economist argued, and would allow for greater economic efficiency by permitting the trading of one gas against another. 

In other words, a utility company or cement manufacturer on the hook to reduce CO2 emissions under a federal climate law could opt to find sources of HFCs and have them destroyed instead. Since HFCs are as much as 11,990 times more potent than CO2, small amounts could substitute for large amounts of CO2 emissions and offer a cheaper alternative to emissions reductions, lubricating the economy to a more gradual embrace of a price on carbon. It also means CO2 emissions would ratchet down more slowly.

The difference of opinion within the administration on one of its signature issues was an unexpected development.

It reflects the surfacing of tensions within two camps on preferred approaches to climate change. On one side is the cautious approach favored by the president's economic team, headed by Larry Summers, who since the 1990s has been wary of imposing emissions controls. On the other is a much more diverse group of agencies acting rapidly in a politically opportune moment.

Reaction to the sudden White House hold up was greeted with dismay among many stakeholders, including industry.

"We do not agree that HFCs should remain in the Kyoto basket and be subject to a full carbon price," Mack McFarland, chief atmospheric scientist of Dupont, one of the leading manufacturers of HFCs, told SolveClimate today. "We believe that HFCs should be treated separately from other gases."

McFarland explained that the gases in the Kyoto basket, most notably CO2, are waste gases, but HFCs are intentionally produced for societal needs, so they need separate handling. Because they can be found in cars, refrigerators and air-conditioners, they cannot be controlled at the point of emissions when they eventually escape into the atmosphere from hundreds of millions of pieces of discarded equipment.

McFarland is also concerned that subjecting HFCs to a carbon price would have a sudden and shocking impact on consumers.

For example, at a price of $25 a ton for CO2, the HFC commonly used in air-conditioners known as R410a would have a value of $50,000 a ton – or $50 a kilogram – because its global warming potential is more than 2,000 times greater than CO2.
