The U is getting rid of the old-fashioned hangtag permit system, but will it seize opportunities to reduce car commuting? |
With the new system, your license plate serves as your permit. Such an approach will certainly be more convenient, although commuter services also claims that amongst the benefits of doing this is a savings of 650 pounds of paper and 450 pounds of plastic.
With a virtual system, however, commuter services could do the following:
- Create a system where instead of purchasing an annual permit, you pay by the day (say $2/day). Every time they scan your plate, your credit card is charged. You just sign up at the beginning of the semester. This incentivizes multimode commuting to campus. Such a system has worked at other universities.
- Add a surcharge for parking on campus on yellow or red burn days. On these days, if you park on campus, it costs an extra $2. Exceptions could be made for low or no tail-pipe emission vehicles and individuals who need to drive for medical reasons. Perhaps something could be done for carpoolers, but that might be more difficult to enforce, although carpooling would be partly incentivized since it would be cheaper to park one car on campus than two or three.
That is a great idea/plan.
ReplyDeleteHow is a no-tailpipe emissions vehicle work pollution-wise when it needs to be plugged into a largely coal- and gas-based electrical grid here in Salt Lake City? If all SLC residents went out and got Nissan Leafs, would our pollution situation improve relative to similar gasoline or hybrid vehicles? Obviously, its a complicated problem, but I'm wondering if you can provide some clarity.
ReplyDeleteThis is a good question.
DeleteIn Utah, about 80% of our electricity is produced by coal. Thus, electric vehicles that obtain their energy from "the grid" are not zero emission. The are only zero emission at the tailpipe (see http://wasatchweatherweenies.blogspot.com/2012/01/can-evs-save-us-from-pollution-during.html).
However, the location of the emissions is different, and that is potentially important for wintertime PM2.5 events. During inversions, tailpipe emissions are essentially trapped in the Salt Lake Valley and contribute to our high PM concentrations. In the case of electric vehicles, however, the emissions are at the power plants, which are usually outside the Salt Lake Valley. Basically, you are moving the emissions to a location where they have a much smaller (often negligible in the case of wintertime inversions) impact on pollution *in the Salt Lake Valley.*
In such a scenario, you would help reduce the frequency and severity of poor air quality events in the Salt Lake Valley, but you still have a regional and global emissions source. For instance, you are still emitting CO2, NOX, mercury, etc., if the energy source is a coal plant. Efforts would need to be made to capture those emissions at the coal plant and/or move to cleaner energy sources (e.g., natural gas, nuclear, renewables) to have an overall decrease in pollution.
