Rethinking Transportation
As part of our Green Sanctuary work in 2007, we will be promoting a greening in how we think about transportation. We all need to think more deeply about how we travel, both locally and throughout the world.
>>American mobility is one of our society's greatest freedoms. We can go places faster and farther than any generation before us. This is a good thing. But our driving and flying contribute mightily to global warming! According to the Union of Concerned Scientists, our travel contributes one-fourth to one-half of the average American household's annual greenhouse gas production. We Americans account for roughly one-fourth of all greenhouse gas emissions worldwide. Our transportation system is responsiblefor one-sixteenth to one-eighth of all greenhouse gases on Earth. What to do? >>Unquestionably, changes in how Americans get around will be one of the ways to deal with global warming. Technological and structural adaptations on the societal level will be necessary. As individuals, our actions seem minor, if not insignificant, but they do add up. If we could reduce our greenhouse gas emissions, that would be a significant beginning. We can each take our own steps toward this goal and, as a congregation, we can make a difference. >>The first thing we can do to produce less greenhouse gases is to use more efficient means of transportation. Automobiles lead the list, not because they are the most efficient, but because virtually all of us use them. If youre buying a car, get a more efficient one (29mpg or better is called "efficient", 41 mpg or better is called "green", by the Carbon Fund). Consider a hybrid, because these cars not only get great mileage, they are "super-low" emission vehicles. The Toyota Prius from 2004 on is capable of a larger battery which can be recharged by wind power, a so-called "plug-in" retrofit: with a plug-in hybrid, driving becomes as low-polluting as is now possible, up to a certain range. Currently the cost of this retrofit is very high, but Toyota says they will provide plug-in hybrids within two years, so the cost will come down. Remember though, hybrids are not essential--any high mileage car, including diesels since 2006, is an improvement. >>When driving a car, ask if each trip is necessary. >>Combine errands as much as possible. If others are going in the same direction, carpool. We are working towards helping members know who their UU neighbors are, so to facilitate carpooling. (in fcat, if there is someone in the congregation with the computer skills we need to complete this, please contact us!!) >>If you have a flexfuel vehicle, use E85 (85% ethanol) gas from the SeQuential Biofuels station at the 30th Ave exit on I-5. Check your cars VIN on their website to see if your car qualifies (85fuel.com/e85101/faqs/cost.php) or go there and theyll look it up. If you have a diesel car, all of them can use biodiesel, also available at this station. These are less polluting fuels. >>However, the E85 fuel has drawbacks because the ethanol is made mostly from corn. First, when all the energy costs are considered (pesticide, fertilizer, tractor and harvester fuel, transport, and fuel production) burning E85 reduces greenhouse gases very little compared with petroleum fuel. Second, corn is a major food source and we are creating a competition between auto fuel for the richer and food for the poorer. Third, Lester Brown points out that corn production is profitable only with government support (your tax dollars.) >>It may sound trivial, but if idling for longer than thirty seconds, turn off the engine to reduce the overall CO2 output. Consider forgoing one -- or more -- car-trips per week, especially for local travel, and use another mode of getting around. See also: your Carbon Footprint calculator (pdf) |
