Monday, January 11th, 2010
This week’s spotlight is on the University of Minnesota and the University of Florida. Also, sustainability education makes USA Today and the NY Times.
1. U of M Energy Conservation Campaign Collects 10,000 Energy Pledges
Growing sustainability from the bottom-up in any community is challenging. Here’s one way that the Golden Gophers are working on it:
Getting 10,000 people at the University of Minnesota to agree on any one subject is difficult. But 10,000 students, faculty and staff do agree on one thing: saving energy on campus is important.
The U of M has just met its goal of collecting 10,000 energy conservation pledges from students, faculty and staff as part of the It All Adds Up campus energy conservation campaign. The 10,000 pledge marked was topped early Thursday after a flurry of pledges came in response to a university-wide e-mail from President Robert Bruininks asking the Twin Cities Campus to take the pledge.
The university rolled out It All Adds Up last spring in an effort to increase campus awareness about how each person at the U could play a part in saving energy. The energy conservation pledge asks individuals to take seemingly small actions – like turning off lights or powering down computers at the end of the day – with the understanding that if each member of the 80,000 person campus community did those small actions, it would all add up.
2. One Less Car Wraps As Alternative Transportation Increases
Here’s another bottom-up approach, and the FL Gators get a gold star for doing it with one of the hardest behavioral modifications—driving:
The second annual One Less Car challenge was a success, with nearly 1,000 people participating. More than 100 teams represented students, faculty, and staff from departments and units across campus. Together, One Less Car participants avoided over 260,000 miles of driving during the challenge. Through alternative transportation commutes, such as busing, biking, and walking, approximately 246,370 pounds of carbon dioxide were kept from entering the atmosphere.
The teams that used alternative transportation for the most miles were: The Office for Student Financial Affairs, The Florida Museum of Natural History, and The College of Dentistry. Final prizes were awarded to the teams with the highest average points per member: Extreme Backroads, Los Tamales Calientes, Radical Gainesville, Geography, and No glass on the bike lanes. Individuals also earned prizes for logging the most trips and avoiding the most miles of driving. Final prizes included: lunch from Satchel’s Pizza, bike tune-ups, Hippodrome Tickets, Gator Dining meal coupons, and tickets to the Butterfly exhibit at the Florida Museum of Natural History.

How do I find a green job?
Thursday, January 7th, 2010
That’s the title of a column over at Grist by Bowdoin alum, Auden Schendler.
What I like about it is Auden’s emphasis on not waiting for sustainable jobs to slap you in the face. Rather, work to turn any job—your life—into a greener enterprise. Those entrepreneurial skills are tremendously important (Teach a man to fish and he’ll eat forever).
His book, Getting Green Done, is a case study on his doing just that at the Aspen Skiing Company.

The promise and perils of algae-based biofuels
Monday, December 28th, 2009
In a forthcoming article1 in Trends in Ecology and Evolution, Val Smith and colleagues describe why biofuels produced from algae have many benefits:
- The current production of biodiesel (~2 billion gallons in 2006) is far lower than annual consumption of diesel fuel (44 billion gallons per year). Simply put, biodiesel crops can’t keep pace with demand. We would have to grow significantly more biofuel crops, which would affect land use by reducing the acreage of food crops or natural habitats.
- Algae fats (lipids) can serve as the feedstocks for many types of fuels, including aviation fuel, which would be a major benefit because airline travel is a huge part of most people’s carbon footprints. Algae fuels are potentially carbon neutral. Making air travel carbon neutral would be a game changer.
- Algae grow extremely fast—much faster than terrestrial plants (which are made into biodiesel or ethanol). They lack anatomical parts like roots, flowers, and woody stems that don’t help plants photosynthesize (making them more productive than plants).
- One of the most amazing statistics in this paper is how much less land it would take to make algae based fuels compared to terrestrial plants because of the increased productivity of algae. To produce an amount of fuel equivalent to the global demand for oil, we would only need an area of land equivalent to 3-20% of current croplands. If we were to use biofuel plant crops instead, we would need about 2-8 times the amount of current global cropland. That’s so amazing I did a double take when I read it.
- Algae can be grown in tanks on lands that are marginally useful for crops so that we don’t have to sacrifice croplands.
- They can serve double-duty by removing excess nutrients from wastewater, thereby linking energy production and wastewater treatment.
- Algal production virtually eliminates the use of herbicides and insecticides and uses much less water than growing crops for fuels.
They also point out an interesting pitfall:
- Bioreactors containing algae are often unintentionally invaded by zooplankton that eat the algae. This can lead to predator-prey-type cycles in algae biomass, which is not good when you want to maximize algal biomass production.
- The solution? Add fish that eat the zooplankton. This would cause “top-down” pressure on the zooplankton, keeping their populations in check.

Small green behaviors: Encouraging or distracting?
Wednesday, December 23rd, 2009
There’s been some debate over the past month as to whether small green behaviors, such as changing out compact fluorescent lightbulbs, spur people to take bigger steps—say, buying a hybrid car, weatherizing a home, or commuting to work.
One camp says no. In a blog post, We cannot change the world by changing our buying habits, George Monbiot argued (links his)
I’ve never been convinced by this argument. In my experience, people use the soft stuff to justify their failure to engage with the hard stuff. Challenge someone about taking holiday flights six times a year and there’s a pretty good chance that they’ll say something along these lines:
I recycle everything and I re-use my plastic bags, so I’m really quite green.
I wasn’t surprised to see a report in Nature this week suggesting that buying green products can make you behave more selfishly than you would otherwise have done. Psychologists at the University of Toronto subjected students to a series of cunning experiments (pdf). First they were asked to buy a basket of products; selecting either green or conventional ones. Then they played a game in which they were asked to allocate money between themselves and someone else. The students who had bought green products shared less money than those who had bought only conventional goods.
The researchers call this the “licensing effect”. Buying green can establish the moral credentials that license subsequent bad behaviour: the rosier your view of yourself, the more likely you are to hoard your money and do down other people.
Then they took another bunch of students, gave them the same purchasing choices, then introduced them to a game in which they made money by describing a pattern of dots on a computer screen. If there were more dots on the right than the left they made more money. Afterwards they were asked to count the money they had earned out of an envelope.
The researchers found that buying green had such a strong licensing effect that people were likely to lie, cheat and steal: they had established such strong moral credentials in their own minds that these appeared to exonerate them from what they did next. Nature uses the term “moral offset”, which I think is a useful one.
More recently, Mike Tidwell had a column in the Washington Post, To really save the planet, stop going green, in which he argued
December should be national Green-Free Month. Instead of continuing our faddish and counterproductive emphasis on small, voluntary actions, we should follow the example of Americans during past moral crises and work toward large-scale change.
….So what’s the problem? There’s lots of blame to go around, but the distraction of the “go green” movement has played a significant role. Taking their cues from the popular media and cautious politicians, many Americans have come to believe that they are personally to blame for global warming and that they must fix it, one by one, at home. And so they either do as they’re told — a little of this, a little of that — or they feel overwhelmed and do nothing.
However, a few days ago, Margaret Southern posted a column, Stop ‘Going Green’ to Save the Planet?, on TNC’s website in which she argued that there are data to back up the notion that small changes do spur us to make bigger ones (emphasis and links hers):
According to Professor Michael Vandenbergh of Vanderbilt University, co-author of “Household Actions Can Provide a Behavioral Wedge to Rapidly Reduce U.S. Carbon Emissions” (published in the Proceedings of the National Academy of Sciences), there is no research to support the assumption that if someone does one good thing (say, bike to work) they would be less likely to do another good thing (support climate change legislation).
In fact, Professor Vandenbergh told NPR that behavior change is contagious:
There are a number of psychological phenomena that suggest that we might actually induce more support for behavior change. When someone becomes committed to a certain behavior, they’re more likely to follow through in other areas as well.
So, those already concerned about conservation might become even more concerned about it as time goes on.
So, while I agree with Tidwell that the conservation-concerned should turn up the heat on Congress and other decision-makers on creating real climate change policies, we don’t have to set aside our green habits — even temporarily — to do so. I don’t think that setting a good example for personal changes that people can make (that collectively would make a huge difference) is confusing people that either don’t know how to change or don’t care to change.

Progress and the good life
Sunday, December 20th, 2009
The cover story of this week’s The Economist, The idea of progress—Onwards and upwards: Why is the modern view of progress so impoverished?, examines an issue central to this blog: What does/should the good life look like?
Excerpts:
In the rich world the idea of progress has become impoverished. Through complacency and bitter experience, the scope of progress has narrowed. The popular view is that, although technology and GDP advance, morals and society are treading water or, depending on your choice of newspaper, sinking back into decadence and barbarism.
….The Economist puts more faith in business than most. Yet even the stolidest defenders of capitalism would, by and large, agree that its tendency to form cartels, shuffle off the costs of pollution and collapse under the weight of its own financial inventiveness needs to be constrained by laws designed to channel its energy to the general good.
Nor does economic progress broadly defined correspond to human progress any more precisely than does scientific progress. GDP does not measure welfare; and wealth does not equal happiness. Rich countries are, by and large, happier than poor ones; but among developed-world countries, there is only a weak correlation between happiness and GDP. And, although wealth has been soaring over the past half a century, happiness, measured by national surveys, has hardly budged.
….And it is not just that material progress does not seem to be delivering the emotional goods. People also fear that mankind is failing to manage it properly—with the result that, in important ways, their children may not be better off than they are. The forests are disappearing; the ice is melting; social bonds are crumbling; privacy is eroding; life is becoming a dismal slog in an ugly world.
….Such values are the institutional face of the fundamental engine of progress—“moral sensibility”. The very idea probably sounds quaint and old-fashioned, but it is the subject of a powerful recent book by Susan Neiman, an American philosopher living in Germany. People often shy away from a moral view of the world, if only because moral certitude reeks of intolerance and bigotry. As one sociologist has said “don’t be judgmental” has become the 11th commandment.
But Ms Neiman thinks that people yearn for a sense of moral purpose. In a world preoccupied with consumerism and petty self-interest, that gives life dignity. People want to determine how the world works, not always to be determined by it. It means that people’s behaviour should be shaped not by who is most powerful, or by who stands to lose and gain, but by what is right despite the costs. Moral sensibility is why people will suffer for their beliefs, and why acts of principled self-sacrifice are so powerful.
People can distinguish between what is and what ought to be. Torture was once common in Europe’s market squares. It is now unacceptable even when the world’s most powerful nation wears the interrogator’s mask. Race was once a bar to the clubs and drawing-rooms of respectable society. Now a black man is in the White House.
There are no guarantees that the gap between is and ought can be closed. Every time someone tells you to “be realistic” they are asking you to compromise your ideals. Ms Neiman acknowledges that your ideals will never be met completely. But sometimes, however imperfectly, you can make progress. It is as if you are moving towards an unattainable horizon. “Human dignity”, she writes, “requires the love of ideals for their own sake, but nothing requires that the love will be requited.”

Sustainable seafood: Does fresh vs. frozen make a difference?
Wednesday, December 9th, 2009
The NY Times is running an op-ed, Catch of the Freezer, by a few ecological economists who were interested in learning whether it’s more sustainable to eat fresh or frozen seafood.
Focusing on salmon as a case study, they suggest that it does matter. Eat frozen when you can to reduce carbon emissions:
When it comes to salmon, the questions of organic versus conventional and wild versus farmed matter less than whether the fish is frozen or fresh. In many cases, fresh salmon has about twice the environmental impact as frozen salmon.
The reason: Most salmon consumers live far from where the fish was caught or farmed, and the majority of salmon fillets they buy are fresh and shipped by air, which is the world’s most carbon-intensive form of travel. Flying fillets from Alaska, British Columbia, Norway, Scotland or Chile so that 24 hours later they can be served “fresh” in New York adds an enormous climate burden, one that swamps the potential benefits of organic farming or sustainable fishing.
There are a lot of other important questions about sustainable seafood, including harvest rates, the industrialization and carbon intensity of the fishing process, genetic modification of farmed species, and organic pollutant loads in wild vs. farmed fish. In terms of transportation and climate warming, this article offers a useful point of view, but I think their statement dismissing the importance of organic and wild vs. farmed is a bit parochial to a discussion of seafood sustainability writ large. It depends on what part of sustainability—warming, human health, fish stocks, genetic alteration—matters most to you.

Innovative ideas for financing home energy efficiency
Wednesday, December 9th, 2009
Let’s face it, how many people have a spare $10k lying around for a new furnace? Not me, and I could use a new furnace.
Home weatherization and efficiency upgrades can make a big difference in U.S. carbon emissions. As we saw in a previous post, American households (including personal transportation) are responsible for
- 38% of the overall US carbon emissions
- 8% of global emissions
- more emissions of any single country except China
Unfortunately, there’s a big disconnect between things we can do to to save home energy and the ability for folks to pay for these improvements. New insulation, solar hot water, solar photovoltaics, high-efficiency furnaces: Take your pick….Each can cost $10k or more.
Fortunately, there are a lot of creative ideas coming to the rescue to help people defray these up-front costs:
- Municipalities can issue bonds that homeowners can borrow from to pay the up-front costs of improvements. The costs of these improvements are then payed back over an extended periods of time through raised property taxes. Homeowners effectively get a zero-interest loan from their cities.
- Banks can issue higher mortgages that include up-front costs for major energy efficiency improvements. These added costs are then spread out over the life of the mortgage, resulting in manageable monthly payments for homeowners.
- Or, the federal government can simply reimburse people for part of the costs of improvements. The so-called “Cash for Caulkers” program reported today by CNN is an example.
These kinds of programs make a lot of sense and have the potential to be game changers, along with helping Americans transition to electric vehicles as soon as possible.

This week’s good ideas in campus sustainability: 12/7/09
Monday, December 7th, 2009
This week, it’s the University of Oklahoma and Florida Gulf Coast University:
(1) Regulators approve ‘OU Spirit’ wind farm plan
This will be one of the largest wind power projects among universities—44 turbines generating 101 Megawatts. Eventually, the university hopes to supply all of its electricity by wind. This is exactly what needs to happen throughout the Great Plains. Hopefully OU will serve as a model for all other states and schools in the region. Maybe we won’t need the Pickens Plan if enough people get on board.
(2) Florida College To Create Green Research Center
Another great example of public, private, and university partners coming together to spur technology, education, and green jobs.
As part of its goal to become a center for renewable energy and green technology research and education, Florida Gulf Coast University has joined the John D. Backe Foundation in a collaborative venture to create Florida Gulf Coast University Innovation Hub, a 1.2 million square-foot, state-of-the-art research and development area.
One of the primary goals of the initiative is to attract businesses and universities with an interest in renewable energy, and spur growth in green jobs, all of which are good for the region, the state and its residents. As more people realize the value of green initiatives and the vital importance of renewable energy, initiatives like the I-Hub and the work that will be conducted at FGCU will play an exciting role in the future growth and prosperity of the region and the state.

This week’s good ideas in campus sustainability: 11/30/09
Tuesday, December 1st, 2009
The showcase this week: Eastern Illinois University and the University of California, Merced.
(1) Honeywell and EIU Bring the Heat with Biomass-Fueled Plant
This is an impressive scaling of biomass energy. It sounds like it’s about two times the size of the biomass gasification plant at Middlebury. By displacing 10,000 tons of coal, this will go a long way in helping EIU move towards carbon neutrality (provided that the fuelwood forests are replanted). However, not everyone is going to be able to do this; otherwise, we’ll end up deforesting all of North America!
Honeywell today announced a $79 million renewable energy and building retrofit program with Eastern Illinois University in Charleston, Ill. The program, which combines energy-efficient facility upgrades with one of the largest biomass-fueled heating plants on a university campus, will help EIU address deferred maintenance, improve its infrastructure, and save approximately $140 million in energy and operating costs over the next two decades.
EIU will finance the improvements and use the savings, guaranteed by Honeywell through a 20-year performance contract, to pay for the work. As a result, the program will not place a burden on the university’s budget or require additional taxpayer dollars or student fees.
The upgrades will impact all facilities on the 320-acre campus, and significantly curb the university’s energy use and greenhouse gas emissions. For example, they will reduce electricity consumption by an estimated 6.2 million kilowatt-hours per year — enough energy to power more than 580 homes annually. Carbon dioxide emissions will also decrease by nearly 20,000 metric tons each year. According to figures from the U.S. Environmental Protection Agency, this is equivalent to removing more than 3,600 cars from the road.
The focal point of the program is the construction of a new steam plant on the southeast corner of campus that will be driven by two large biomass gasifiers, the first application of this technology in the region. The plant will use wood chips sourced from the local logging industry to generate steam and heat buildings on campus. And it will replace the university’s aging steam plant, which is inconveniently located in the center of campus, consumes more than 10,000 tons of coal per year and requires constant maintenance.
(2) UC Merced Unveils New Solar Power System
This is another ambitious effort. Hopefully opportunities like this will become commonplace in the next five years as solar panel costs continue to decline.
The University of California, Merced announced today (Nov. 10) the completion of a 1 megawatt solar power system at the campus, marking the university’s inaugural effort to produce clean, renewable energy as the first American research university of the 21st century.
“We are here today to celebrate a remarkable milestone,” said Mary Miller, vice chancellor for administration. “The solar array project exemplifies UC Merced’s founding vision to become an international model for sustainable development and environmental stewardship.”
The system is located on 8.5 acres southeast of the Science & Engineering Building. It consists of 4,900 solar panels that follow the sun’s movement during the day. The system will supply two-thirds of the campus’ electricity on summer days and 20 percent of the campus’ annual electricity needs.
The solar array will provide UC Merced with an abundant source of clean, renewable power. According to conversion formulas provided by The Climate Registry, the system is expected to remove more than 45 million pounds of carbon dioxide over the next 30 years. That is equivalent to the emissions displaced from removing more than 3,600 cars from California’s roads.
