Eat Fluffy or Get Rid of the Family SUV?


A tough choice for any family, but according to a new study recently published the family dog looks to be contributing more to global warming than that favorite villain of environmentalists... the SUV. Read the full story here.

This really is disappointing news, if only this study had been published before I went on my carfree crusade I could have saved myself a lot of useless headache. Part of my reasoning for going carfree for a year was to reduce my ecological footprint, but it seems this new study gives me an easier alternative.

Rather than giving up my '83 Toyota Landcruiser that only gets 14 miles-to-the-gallon I could have been practicing a little population control on the neighborhood dogs, having a tasty meal, and saving the planet all at the same time. I could be out there stalking around my neighborhood at night dressed all in black luring neighbor's dogs out with the promise of steak, then capturing them for my planet saving plan... just garnish with some seasoning and a side of baked potatoes. I could still be driving around with a clean conscience and I could have had more of an impact than by giving up on driving... all the while hot having to screw around with riding a bike in subzero temperatures.

Now, I am only kidding as I never intentionally eat such a meal. But it is amazing to think that a pet could be twice as harmful to the environment as an SUV, mainly because of the food that we feed them. I think this study is great because pet ownership is something that most American enjoys and also an aspect of people's live that hasn't received such an analysis. The impact of our transportation and food systems are well known, continually being debated and revised. But pet ownership is something that completely fell under the scope of any analysis. I doubt this will seriously wake people up to the idea of getting rid of fluffy, but maybe it will inspire more debate and a new look at our collective ecological footprint.

Solutions to Climate Change must focus more on behavior and less on technology

Much of the focus this week in the media has been centered around the summit in Copenhagen focusing on climate change and the pledges of governments to cut emissions. But the media misses half of the solution in many cases; only focusing narrowly on technologies that can combat global warming and largely ignoring how people's behaviors are the true culprits of green house gas emissions. While a hybrid vehicle might be better than a regular SUV, a bike is even better and a person changing their behavior from driving to biking will do more for the environment than simply changing the tool that people use to express their everyday behavior.

An article in the Mother Nature Network by Ken Edelstein got me thinking about this subject. Even so called "Green" media outlets such as Treehugger and EcoGeek, when covering a topic such as transportation, usually discuss the latest hybrid or electric vehicle rather than the much more green option of not driving at all. Four out of seven of today's top articles in the transportation section of Treehugger are about cars. As Ken points out in his MNN article, stories about the latest in vehicular technologies provide a Wow factor that connects with American's love affair with the car

But I think it goes deeper than that and our current economic downturn can provide a little bit of insight. With the economic downturn everyone is suffering, not least of all the media industry and people don't like change. There is a big emphasis on the need for recovery and for things to get "back to normal." By normal I mean more cars sold, more vehicle miles traveled, more consumption, and a bigger than last year holiday sales season. Media outlets especially want this so that their advertising revenue can return to normal. I'm not claiming this is some conspiracy, it is just that people and media outlets perceive "back to normal" as being in their interest.

Thats why we have a government that wants us to go out and spend and a stimulus package that is designed to inject money back into the system. In Obama's opinion it is better to saddle us with debt so that we can spend now than it is to be frugal and let creative destruction take affect and reorganize our economic system. Its the same policy Bush put in place after the Dotcom bubble and 9/11; lower taxes, borrow more, and take out your credit cards and go to the mall.

Rather than learn lessons from my grandparents generation that had frugality and self reliance forced on them by the Great Depression, we are trying to spend our way out of the mess we created when we borrowed and spent too much in the first place. We are attempting to prop up an outdated economic system, one based on perpetual growth, consumption of ever more resources, and unlimited sprawl.

As Ken points out:

Even though repair backlogs can stretch years or decades into the future, nearly one-third of (stimulus)
money, $6.6 billion, went towards roadway new capacity projects. At a time when public
transportation ridership is hitting all-time highs and the budget crunch is causing transit agencies to cut
routes, service and jobs, an abysmal 0.9% was spent on public transportation. Only 2.8% percent was spent
on non-motorized projects (i.e., bike and pedestrian projects).


And that brings me back to our behavior. We can thrive on producing and consuming less because by doing so there is the potential to unleash previously locked up resources to create whole new business models, local economies, and industries. Economists for the longest time worried about the loss of union jobs in manufacturing because the jobs that replaced those lost usually payed less. William Travis in his book, New Geographies of the American West, cites two University of Montana economists, Thomas Powers and Richard Barret, who found that supporting such "old economy" industries such as manufacturing and resources extraction actually held back the Montana economy from developing faster and better allocating scarce resources of capital and labor. While manufacturing and union jobs have constantly declined since the '70s America is rich not poorer because of it.

Part of the problem is obviously design, as our cities, road networks, and economic connections are all designed to work toward moving vehicles, goods, and money through the system as fast as possible. Thats why the financial collapse happened. All of a sudden when a banks payment of a loan was held up by a second bank's inability to pay the first bank, the whole system came crashing down in a matter of days. Its the same with our cities, if we only connect communities with roads designed for cars, there will be no opportunity for a community to connect through walking and biking and that community will miss out on an opportunity to organize itself and social and economic activities around such activities

By changing behavior, i.e. consuming less, driving less, working less, we don't have to sacrifice our quality of life and can actually improve it while at the same time lessening our impact on the environment. Change can be a scary thing for many people because of the uncertainty that it fosters. But if people are serious about combating climate change and at the same time developing more resilient economies that offer opportunities for the future we have to focus on behavior and not just the technology.

David Orr on Post-Carbon Cities


Missoula was lucky enough yesterday to have David Orr in town. In between the meetings usual social events, there was enough time for him to give two lectures at the University of Montana.

For those of you who don't know of David Orr, he is a leading thinker and innovator environmental issues, green building, and ecological design. Within the last decade he gained national press for his effort and subsequent success in building a fully carbon-neutral building on the campus of Oberlin College which can be seen above. It integrates passive solar design by orienting the building to take advantage of the suns energy, a roof fully covered by solar panels, sustainable materials, food production in the form of a garden and orchard on the north side of the building, and environmental restoration on the wetlands immediately adjacent.

David Orr covered post-carbon cities in the lecture I attended. The scope of his talk was extensive, delving heavily into the philosophy behind green building/urban design. What resounded with me was his call to take a systems approach to issues. He blames academia for the tradition of reductionist thought that breaks issues/objects into components without concerning itself with how the whole works or interacts with the world. He used the example of optimizing the Hvac system of a building without also optimizing the insulation or materials used in the building.

By taking a systems or wholistic world view we can come to better understand the world and the interaction between our actions and the environment. This is true of economics - which as a student of economics I fully agree with - where one doesn't pay the full cost of any product. Externalises exist everywhere and with every purchase; a vehicle doesn't really cost only $20,000 if you include the pollution from its manufacture and operation, the cost of the roads it travels, and the cost of disposal, etc. If all these costs where taken into affect, our world would be a much different place. There would be no coal fired power plants if the coal industry had to directly pay for every death caused by the pollution it creates.

Back to post-carbon cities. David has an ambitious goal of turning Oberlin into a carbon-neutral city, starting by redeveloping the downtown area to be an eco-village. He is taking a ground up approach by gathering support and investment from within the community. This seems like a much better approach for such a project than the one taken by Saudi Arabia and China in attempting to build their own respective eco-cities, both of which after years of being in the design and planning phases have gone nowhere.

Of course, building a fully carbon-neutral town is a big challenge, as not only do the buildings have to be redesigned, but people's behavior's have to radically change and a whole new local economy built from scratch. If David Orr has any misgivings about such a project, its is that he doesn't know whether people are willing to do what needs to be done to create such an ecologically friendly future.

He is optimistic in terms of having all the tools ready and at his finger tips. David talked of how over the last thirty years scientists and entrepreneurs have developed the tools to create such a future and now everything simply has to be brought together and integrated. Social awareness has also progressed enough to allow the building of such a future. This is especially true within professions that can move something such as eco-cities along. Daniel Narrin over at Discovering Urbanism illustrates this point in a recent post. Having found a planning text book from the early 1990s, he was surprised to see how far the profession has developed in two decades, having found that the book never once mentioned pedestrians or cyclists and describes environmentalists only as obstructionists against progress.

It now seems very possible that the environmentalists so reviled by many only two decades ago will be the ones innovating and creating our future as it has gone from a movement of obstructionism to one of practical application and problem solving. Best of luck to David Orr and his vision of a carbon-neutral future, I hope to experience it one day.

Book Review: After The Car

Full Disclosure: I received a free copy in return for this review

Despite the provocative title and front cover of the book, After The Car by authors Kingsly Dennis and John Urry, there is little radical thought or ideas that give a blueprint on how our society will organize after the decline of the personal automobile. That said, if you are new to how personal transportation issues relate to global climate change, economics, social organization, and urban design, than this book gives a short and concise summary that provides a good overview of all these issues. Overall After The Car is a well-written and well-thought out book that is concise and covers a lot of ground in a very small package.

At a mere 164 pages, After The Car, takes the reader through a handful of today's most pressing issues. The first chapter quickly explores the situation we find ourselves in today, including climate change, peak oil, the growth of the Internets, and the supremacy of urban areas. This quick overview sets the stage for the rest of the book and for how we got to the situation we find ourselves in today.

The heart of the book delves into how the car came to completely reshape our lives. At one time the automobile was a new and disruptive technology. At the beginning of the car's history it transformed the lives of millions of people and led to a huge leap in productivity. But after a century of the car's dominance it has come to signify, "...many of the most troubling aspects of human civilization."

The authors take the view that the dominance of the car is thanks to the convergence of various trends such as allowing for freedom of mobility, the huge increase in economic productivity it allowed, and the complete seepage of car culture into the fabric popular American culture. But this wholehearted acceptance of the car has led to unintended consequences. The car system's full adoption by society has come to mean high levels of pollution, possible climate change, economies that are held back by the maintenance of sprawling transportation networks, and the adverse social affects that come with being so spread out and disconnected from one's neighbor.

As for my aforementioned disappointment, once the book finally makes it to a diagnosis for our future, there is very little in the way of new thinking and rather mostly a simple summary of current trends that might come to partially supplant the current transportation system. The trends covered include denser living through new urban design, rapid personal transit, electrical vehicles (EVs), and green cities. The authors express great hope in the idea of green cities such as Dongtan China, even though most of the over hyped green trophies are still just nice drawings on some government official's desk.

The criticism I can't get out of my head is talk of how EVs and biofuels will be a part of the solution. For a book entitled After The Car it seems a bit of contradiction to propose that EVs and biofuels will really change anything. How many trillions of dollars will ultimately need to be spent on infrastructure to build generating capacity just to power our EVs and how little will that investment reduce our green house gas emissions? This is a question that the authors simply gloss over.

Overall, After The Car, does an excellent job of giving a concise overview of many of the issues that will shape our new century and how that could affect our transportation system. But there is little revolutionary thought held within the pages of the book, and despite the title, there is almost no vision of our future after the car.

Infrastructure Needs to be Factored in on Long-Term Transportation Cost/Carbon Emissions Calculations


Tracy White recently left a comment on an old blog post of mine that discussed the per-mile Carbon Dioxide emissions of different modes of travel. She brought up an excellent point that infrastructure costs and resource-use needs to be taken into account in cost-benefit analysis.

She even conveniently linked to an abstract of a research paper that indicated that adding such information to the analysis can significantly add to the lifetime energy use and greenhouse gas emissions (GHG). The study's abstract finds... "that total life-cycle energy inputs and greenhouse gas emissions contribute an additional 63% for onroad, 155% for rail, and 31% for air systems over vehicle tailpipe operation."

This seems like a a substantial impact... and I'm sure that it is. But the headline numbers touted in the abstract can be misleading. Now, I will admit that I have not taken a look at the full text of the study. Rail's impact on a per mile basis is much lower than that of cars, especially SOVs. It is because rail starts out at such a smaller GHG impact that the increase is so much higher when infrastructure is taken into account.

I'm sure that rail's lifetime environmental impacts are still much lower than that of vehicles, and from the research I have seen that is what people are finding. I'll have to dig into the study a little more when I have the time. Thanks Tracy for bringing up a great point that needs to be considered in these types of issues.
