<div>Just to make things more complicated ... </div> <div> </div> <div>With cars, energy consumption is not just a matter of miles driven, but also manufacturing. Manufacturing, according to a Carnegie-Mellon study, accounts for 10 percent of energy consumed and more than half the toxic releases over a car's lifetime (<A href="http://www.ilea.org/lcas/macleanlave1998.html">http://www.ilea.org/lcas/macleanlave1998.html</A>).</div> <div> </div> <div>The analysis is based on a 1990 Ford Taurus with an expected lifetime of 14 years. Although a direct extrapolation to older/newer cars and manufacturing plants isn't possible, you might guess that keeping an old clunker running wouldn't be the worst thing in the world, if it were to delay the creation of a new car.</div> <div> </div> <div>Kevin</div> <div> </div> <div> </div> <div> <BR><BR><B><I>jthorn65@sbcglobal.net</I></B> wrote:</div>
<BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">I too love big old cars and have a few of them. In itself this would hardly seem a reason to reject climate change <BR>or reject the idea of autos as contributing a significant portion to the CO2 problem. That's said I pollute less <BR>driving my big old V8 to Florida from Missouri than someone who takes a flight there on a plane seating under <BR>60% of it's capacity. My car does not need 105 AvGas with lead and run with absolutely no pollution control <BR>devices. I have installed a MPFI system with Cat back exhaust. On a per gallon basis it pollutes somewhere <BR>between a new SUV and new automobile. Anyone who gets on an airplane to do something other than cross an <BR>ocean is more likely than not having more pollution dumped into the environment than a person driving a newer <BR>car to the same destination. Cars are no more a problem than airplanes or the trucks that
inefficiently haul <BR>everyones groceries to their destination.<BR><BR>John Thornton <BR><BR></BLOCKQUOTE><p>
