Power-plant data flawed, ASU team finds

Small nationwide median difference masks large variation at some facilities.
Problem is fixable — now that we know it's there, ASU scientist says.

Inaccurate numbers for carbon dioxide emissions undermine Clean Power Plan

Federal data on power-plant carbon dioxide emissions is significantly flawed, according to a study by Arizona State University scientists published this month.

Monthly emission differences at a fifth of U.S. power plants varied plus or minus 13 percent. At half the plants, differences varied plus or minus 6 percent.

Inaccurate data undermines the federal Clean Power Plan, which is designed to strengthen the trend of clean energy by setting a national limit on carbon pollution produced from power plants.

“I would say that, in order for that piece of policy to be as effective as I’m assuming everyone wants, we need to make sure we’re monitoring and measuring power plants accurately,” said Kevin Gurney, lead author of the study. GurneyGurney is a senior sustainability scientist in the Julie Ann Wrigley Global Institute of Sustainability and an associate professor in the School of Life Sciences in the College of Liberal Arts and Sciences. is an atmospheric scientist, ecologist and policy expert working in carbon-cycle science, climate science, and climate-science policy.

Gurney (left) was “pretty darn surprised” by the findings.

“That’s too much error,” he said. “You can’t implement and enforce a policy with that type of error.”

Power plants are responsible for roughly 40 percent of carbon dioxide emissions nationwide. Climate-change science, air-pollution regulation and potential carbon-trading policies rely on accurate measurement of emissions. Two U.S. federal agencies — the Department of Energy and the Environmental Protection Agency — tabulate the emissions from U.S. power plants using two different methodological approaches.

The scientists analyzed those two data sets and have found that when averaged over all U.S. facilities, the median percentage difference is less than 3 percent. However, this small difference masks large differences at individual facilities.

“Power-plant emissions have been looked at for a long time, but they’re typically examined in the aggregate — ‘Here’s the whole U.S.,’” Gurney said. “They just haven’t been looked at individually or analyzed individually. That of course is where the problem arises.”

Differences that large at individual plants raise concerns over implementing the Clean Power Plan.

“This policy relies on the achievement of state-level CO2 emission-rate targets,” the authors wrote. “When examined at the state level, we find that one-third of the states have differences that exceed 10 percent of their assigned reduction amount. Such levels of uncertainty raise concerns about the ability of individual states to accurately quantify emission rates in order to meet the regulatory targets.”

It’s fixable, according to Gurney.

“It’s just that no one has paid attention,” he said. “I think that just a little bit of recalibration and consideration of good instruments, and a little more transparency from utilities, and it can fixed.”

The Clean Power Plan requires individual states to meet specific standards. Currently the plan is tied up in court; resolution is not expected this election year.

Young African leaders find innovation at ASU

Community service a key part of the Mandela Washington Fellows program.
50 fellows studying civic leadership, public management this summer at ASU.

Mandela Washington fellows learn from faculty, perform community service as they create solutions for their communities

Fifty young African leaders who are visiting Arizona State University will take home memories of the scorching summer heat, but they also will carry back new ways to improve their communities.

The group is part of the Mandela Washington Fellowship for Young African Leaders, and they are in the United States for six weeks, including academic work at ASU, community service and a meeting with President Barack Obama in Washington, D.C. This is the third year of the fellowship programThe costs are paid by the U.S. Department of State., begun in 2014 as the main part of Obama’s Young African Leaders Initiative.

“I have never been to so much heat ever in my life, but I’ve also never been to a good university that is very well organized,” said Borso Tall, who is a Mandela fellow from Senegal.

Tall is one of 1,000 Mandela fellows from Sub-Saharan Africa who were selectedThere were more than 50,000 applicants. to study at 36 universities in the United States this summer in one of three tracks: civic leadership, public management, and business and entrepreneurship. ASU is one of only four universities with two Mandela cohorts — 25 in the civic-leadership track and 25 in public management.

The fellows are between the ages of 25 and 35 and are selected based on their accomplishments in their home countries. Many own their own businesses, lead non-profit organizations or teach. While here, each scholar develops a project that he or she can implement in his or her communitiesBack home, they will get continued support, such as mentoring and training, from U.S. embassies, Regional Leadership Centers, the Young African Leaders Initiative Network and other partners..

They have 100 hours of academic instruction and spend five days in community service at agencies around the state, according to Dana Newell, assistant dean of the College of Public Service and Community Solutions, which hosts the Mandela program at ASU.

“One of the things that makes ASU unique is that everyone on the faculty and community-partner side is volunteering for this,” she said. “That’s very unique in a university structure, and it shows ASU’s level of commitment to community engagement and how much we care about these global initiatives.”

Newell said that the community-service piece is huge.

“Last summer, our fellows went to the Community Food Bank of Tucson and packed enough food to feed over 6,000 families.”

This year’s projects include work with Habitat for Humanity in Flagstaff and Ben’s Bells and Roosevelt Row Community Development Corp. in Phoenix.

But there also is time for fun.

“I cannot wait to go to the Grand Canyon,” Tall said. “I have seen it in postcards and movies, but I never thought I would see it.”

'Everyone has a role to play'

In their first week together, the fellows gathered at the Sun Devil Fitness Complex on ASU’s Downtown Phoenix campus for team-building activities.

The young people hopped, squirmed and slid across the shiny floor, clasping hands as they competed to see which team could reach the finish line first while still touching each other.

After the challenge, the 25 participants sat in a circle and dissected the results of their teamwork.

“Leaders aren't always in the front,” Tall said. “Leaders can be in the front, in the middle or in the back. Everyone has a role to play in the process.”

Darlington Muyambwa said that no one should sit back and not participate.

“We have to have the hunger of wanting to be part of the conversation. We need the willingness and eagerness to engage,” said Muyambwa, who wants to establish a center for youth employment in his home country of Zimbabwe.

Concerned about human rights

The projects are the core of the fellows’ work. All of the participants have a vision for a way to help their communities.

Andry Rakotomanana is an English teacher at a school in Madagascar with a bachelor’s degree in computer science.

“I have noticed that students are very motivated for Facebook, so I would like to create a social network for education,” he said.

The digital platform would connect high school students, college students, teachers and professionals to provide career counseling.

“Then everyone can advise high school students for their futures,” Rakotomanana said.

“My goal as a future professor at the university would be to have an officially recognized human-rights program in my department,” she said.

She was impressed with the School of Social Work in the College of Public Service and Community Solutions at ASU.

“It was awesome to see so many people in social work and so many people concerned about human rights,” she said.

“In my country, social work is not in the university — it is a separate training school. All of this collaboration will give me the support I need to add that program to my university.”
