of using an Uber per mile, which was 90 cents according to Uberestimate.com. Since our initial
analysis was based in various scenarios rather than subcategories of the lifecycle, we did not take
into account anything past stage 0. We did this because we were more interested in these values
from the point of the consumer rather than the company.

Base Scenario
The base scenario provides a rough estimate of CO 2 emissions from three different
processes in the automobile sector. According to the 2002 EIOLCA tool, automobile
manufacturing emits 412 tCO 2 e and automobile maintenance and operations emits a total of
tCO 2 e. Based on our assumption that the average car travels 11,244 miles annually, a
conventional car emits a total amount of 77.4 tCO 2 e. The base scenario values are affected in
each of the following cases.
Case
In case 1, CO 2 emissions from car manufacturing dropped to 4.1 tCO 2 e, a percent
decrease of 99%. Moreover, car maintenance and operations also decreased by 99% to 2.
tCO 2 e. Lastly, emissions from driving remained constant.
