Program to Curb 'Black Carbon' Pollution on Obama's Chopping Block

EPA 's budget eliminates a $60 million program to curb soot, as UN scientists report that tackling such pollutants is key to fighting climate change

WASHINGTON—Environmental organizations weren't feeling any love on Valentine's Day when the White House announced that it would slash funding for retrofitting dirty diesel engines in the 2012 budget.

Now they're hopeful an enlightening report about the climatic benefits of curbing soot and ground-level ozone emissions will force President Obama to experience a change of heart.

Remarkably, slicing these pollutants on a worldwide basis by 2030 could halve the projected increase in global temperatures in the first half of the century, according to a report issued by the United Nations Environment Programme (UNEP) this week.

The study, "Integrated Assessment of Black Carbon and Tropospheric Ozone," points out that regulators would be wise to focus on soot and ground-level ozone in tandem with reining in carbon dioxide emissions.

Its authors say that reducing black carbon and ground-level ozone, which includes methane, has a more immediate effect on climate because they have short lifetimes. Carbon dioxide, on the other hand, lingers in the atmosphere for much longer periods.

Dirty diesel engines emit black carbon, a major component of soot, as well as tiny particulates and nitrogen oxides that contribute to the formation of ground-level ozone.

"It blows the mind that the Obama administration would ever consider cutting a program that's so popular and cost-effective," Frank O'Donnell, president of the advocacy group Clean Air Watch, told SolveClimate News in an interview. "This new study underscores how the administration has gone off in wrong direction on this issue.

"To suddenly give the impression they've solved the problem is ludicrous," he continued, "given that there are still millions of dirty diesel engines out there."

EPA Chief Explained Cuts Earlier

Though green groups suspect the White House forced the budget cut on the Environmental Protection Agency, Administrator Lisa Jackson stoically referred to the lopping of the clean diesel grants program as "one of the tough decisions we had to make" during a Feb. 14 teleconference with reporters.

EPA's Diesel Emission Reduction Act grants (DERA) program — scheduled to be zeroed out next year — received $60 million in funding in the 2010 budget. Jackson told reporters that about half of the $100 million allotted to the clean diesel program via the 2009 American Recovery and Reinvestment Act is still unspent.

The grants cover strategies that include retrofitting, rebuilding and replacing older and dirtier diesel engines.

"As millions of families are cutting back and spending less, they expect the same good fiscal sense out of their government," Jackson said in a statement the same day she told reporters that the 2012 budget reduces the EPA's overall budget from a 2010 high of $10.3 billion to $8.87 billion. "This budget focuses our resources on the most urgent health and environmental challenges we face."

Diesel Cuts Surprise Everybody

Democratic Sen. Tom Carper of Delaware, a longtime champion of what are known as DERA grants, told SolveClimate News he will lead a movement to push the White House to restore funding. And he's equally puzzled by the administration's about-face on the money.

"The United Nation's report confirms this link between black carbon and climate change," Carper said in an e-mail, adding that he has requested an EPA report on the same topic.

"DERA leverages federal dollars so efficiently that for every $1 invested, we get over $13 in health and economic benefits in return. This huge return on a relatively nominal investment seems like a good deal for the taxpayer."

And the program isn't a single-party issue either.

For instance, GOP Sens. Jim Inhofe of Oklahoma and George Voinovich of Ohio (now retired) enthusiastically supported legislation that the upper chamber passed Dec. 16 authorizing $100 million in grants annually from fiscal 2012 through 2016. The House passed a companion bill Dec. 21 and President Obama signed the measure into law Jan. 4.

A broad coalition of more than 530 environmental, public, industry and labor groups also backed the program.

Diesel engines can operate for at least 20 to 30 years, according to EPA officials. Information from Carper's Web site indicates that each year DERA grants clean up at least 14,000 diesel-powered vehicles and heavy equipment. The EPA estimates that 11 million diesel engines nationwide lack the latest pollution control technology.

"It's still unclear why it happened," O'Donnell said about the White House 180-degree turn on the funding. "Maybe they wanted to shift money to some other program or inflate the amount of budget cuts, expecting Congress to reinstate the money."

EPA Touts Diesel Program

"Due to the sheer numbers of engines in use and the volume of pollutants they emit, the health effects and environmental pollution stemming from diesel emissions could be substantial," EPA authorities wrote in a report presented to Congress in 2009 that touted DERA's successes.
