Palm oil production a source of heat-trapping methane
Mar 13th
are a climate concern, CU-Boulder study says
In recent years, palm oil production has come under fire from environmentalists concerned about the deforestation of land in the tropics to make way for new palm plantations. Now there is a new reason to be concerned about palm oil’s environmental impact, according to researchers at the University of Colorado Boulder.
An analysis published Feb. 26 in the journal Nature Climate Change shows that the wastewater produced during the processing of palm oil is a significant source of heat-trapping methane in the atmosphere. But the researchers also present a possible solution: capturing the methane and using it as a renewable energy source.
The methane bubbling up from a single palm oil wastewater lagoon during a year is roughly equivalent to the emissions from 22,000 passenger vehicles in the United States, the analysis found. This year, global methane emissions from palm oil wastewater are expected to equal 30 percent of all fossil fuel emissions from Indonesia, where widespread deforestation for palm oil production has endangered orangutans.
“This is a largely overlooked dimension of palm oil’s environmental problems,” said lead author Philip Taylor, a postdoctoral researcher at CU-Boulder’s Institute of Arctic and Alpine Research (INSTAAR). “The industry has become a poster child for agriculture’s downsides, but capturing wastewater methane leaks for energy would be a step in the right direction.”
The global demand for palm oil has spiked in recent years as processed food manufacturers have sought an alternative to trans fats.
For now, the carbon footprint of cutting down forests to make way for palm plantations dwarfs the greenhouse gases coming from the wastewater lagoons. But while deforestation is expected to slow as the focus shifts to more intensive agriculture on existing plantations, the emissions from wastewater lagoons will continue unabated as long as palm oil is produced, the researchers said.
However, the climate impact of the leaking methane could be mitigated by capturing the gas and using it to fuel power plants. Biogas technology has been used successfully for decades and it can produce renewable electricity at a cost that’s competitive with traditional fuels, the authors said.
The amount of methane biogas that went uncollected from palm oil wastewater lagoons last year alone could have met a quarter of Malaysia’s electricity needs. Tapping into that unused fuel supply could yield both financial and environmental benefits, the authors said.
Capturing methane at wastewater lagoons could be encouraged by making it a requirement before palm oil products can be certified as sustainable, the authors said. Current sustainability certifications do not address wastewater emissions.
Taylor, whose research typically focuses on carbon cycling in old-growth tropical forests, was inspired to do the analysis by undergraduate researcher Hana Fancher, who also is a co-author of the journal article. Fancher and Taylor were doing research in Costa Rica, where palm oil production is spreading, when Fancher became curious about how the oil was being processed.
“She has a wastewater background,” Taylor said. “She ended up doing an honors thesis on palm oil agriculture and wastewater emissions. This paper is an extension of that thinking.”
Other co-authors from CU-Boulder include Associate Professor Diana Nemergut, doctoral student Samantha Weintraub and Professor Alan Townsend, in whose lab the work was based. Other co-authors include Cory Cleveland of the University of Montana, William Wieder of the National Center for Atmospheric Research and Teresa Bilinski of St. Edwards University.

CU symposium: Is digital journalism an oxymoron?
Mar 6th
at CU-Boulder symposium March 14-15
Students, scholars and media professionals will discuss media “in the fast-paced world of digital journalism” at a University of Colorado Boulder symposium March 14-15.
CU-Boulder’s Journalism and Mass Communication program will host the conference including two talks that are free and open to the public.
Jay Rosen will give one of the talks on March 14 at 10 a.m. at the Old Main Chapel. Rosen, who will discuss “The Ethics of Point-of-View Journalism,” is a journalism professor at New York University and a media critic. He is an adviser at First Look Media, a new venture featuring the work of Glenn Greenwald, who published the explosive national security documents leaked by former government contractor Edward Snowden. Rosen also writes the blog PressThink.
At 2 p.m. on March 14 at the Old Main Chapel, Steve Buttry will present “Upholding and Updating Journalism Values.” Buttry is the digital transformation editor for Digital First Media. The company operates about 800 multi-platform media products nationally, including several in Colorado. He is a prominent consultant in digital journalism and author of the blog The Buttry Diary.
During other portions of the symposium, participants will explore issues such as the loss of the “ethics support group” found in traditional newsrooms for today’s freelancers, developers and entrepreneurs; today’s ethics challenges in the journalism work environment; and what the latest research and journalistic practice says about norms and values in the digital age.
“Technology has enabled new forms of public communication that raise new kinds of ethical questions,” said Paul Voakes, CU-Boulder professor of journalism and mass communication. “For example: When corrections can be made seamlessly and instantly online, is first-time accuracy now overrated? What are the appropriate journalistic uses of drones? In a profession increasingly populated by developers, activists, entrepreneurs and volunteers, where does a code of ethics fit?”
Excluding the two public talks, symposium participants will work in groups to write brief papers about the issues discussed. The papers could lead to collaborative essays or research projects, according to symposium organizers.
The symposium is supported by the Ethics and Excellence in Journalism Foundation, Colorado State University and the Association for Education in Journalism and Mass Communication.

Florida reporters win Al Nakkula Award for Police Reporting
Mar 4th
Two Florida reporters have won the 2014 Al Nakkula Award for Police Reporting from the University of Colorado Boulder’s Journalism and Mass Communication program and the Denver Press Club.
The $2,000 Nakkula prize goes to reporters Megan O’Matz and database editor John Maines of the South Florida Sun Sentinel for their series, “Cops, Cash, Cocaine.” The piece uncovered a police department’s secret scheme to lure drug dealers to a small town, entangle them in a sting and pocket money from the operation.
The award is named in honor of the late Al Nakkula, a 46-year veteran of the Rocky Mountain News whose tenacity made him a legendary police reporter, according to award organizers. The contest has existed since 1991 and this year drew more than two dozen entries from major publications around the country including the Los Angeles Times, the Seattle Times, the Boston Globe and Newsday.
Five veteran reporters, who worked at the Rocky Mountain News before its closure in 2009, judged the contest. Most of the reporters worked with Nakkula.
“The Sun Sentinel’s report stood out for the sheer doggedness of the reporting and the sheer audacity of the operation the newspaper exposed,” said Nakkula award judge Kevin Vaughan, an investigative reporter for Fox Sports.
Reporters O’Matz and Maines found that the Sunrise, Fla., police department enticed drug buyers to come to town, arrested them, confiscated their cash and cars and kept millions in proceeds. The officers who participated also received hundreds of thousands of dollars in overtime pay.
“ ‘Cops, Cash, Cocaine,’ was one of those stories that allowed Megan O’Matz and John Maines to deploy the skills they have become known for around here: piecing together bits of information, reviewing documents endlessly, talking to sources and checking things out in person. In other words: old-fashioned tenacity,” said Howard Saltz, Sun Sentinel editor.
“The result of their investigation not only revealed something that still boggles the mind when you read it, but served the community by forcing a highly unusual — and arguably dangerous — police operation to shut down,” he said.
O’Matz has received numerous state and national honors for previous work and was a 2006 finalist for the Pulitzer Prize in investigative reporting.
Series co-reporter Maines has been a database editor for the Sun Sentinel for 16 years. He and a Sun Sentinel colleague won the 2013 Pulitzer Prize for Public Service.
Second place in this year’s competition was awarded to reporters John Diedrich and Raquel Rutledge of the Milwaukee Journal Sentinel for their series, “Backfire.”
The judges also sent a special commendation to the staff of the Pittsburgh Post-Gazette for the depth and breadth of their work in 2013. The staff entered two major reporting projects in the contest.
