However, choosing an e-scooter over driving a personal automobile with a fuel efficiency of 26 miles per gallon results in a near universal decrease in global warming impacts. In our analysis, we test a wide range of plausible scooter lifetimes (0.5–2 years), informed by battery lifetimes, the manufacturer warranty, and reports of damage under shared usage programs [To better understand the net impacts of e-scooter usage, we compare our results to alternative modes of transportation. You will only need to do this once. Without these efforts, our Base Case calculations for life cycle emissions show a net increase in global warming impact when compared to the transportation methods offset in 65% of our simulations.

We test a range of parameter values to assess each input's sensitivity and ensure broad applicability of results. When compared to the Benchmark Displacement COIn this study, we found that the global warming impacts associated with the use of shared e-scooters are dominated by materials, manufacturing, and automotive use for e-scooter collection for charging.

The shared dockless bicycles represent non-electric bikes that require 'rebalancing' [These results show that dockless e-scooters consistently result in higher life cycle global warming impacts relative to the use of a bus with high ridership, an electric bicycle, or a bicycle per passenger-mile traveled. Shared stand-up electric scooters are now offered in many cities as an option for short-term rental, and marketed for short-distance travel. The electricity impacts of charging use seasonal marginal emissions factors from Azevedo E-scooter employees (chargers) can collect any scooters at any location in the city once the scooters become available for collection, without specified collection routes, areas for pick-up, or specified scooters. Requiring central management or improved e-scooter collection processes could reduce the auto-miles traveled for collection and distribution. The results of a Monte Carlo analysis show an average value of life cycle global warming impacts of 202 g CO Original content from this work may be used under the terms of the With a small electric motor and a deck on which a single rider stands, stand-up scooters are designed to transport riders short distances around urban settings. To properly bound this comparison, we conducted a survey of 61 riders and use another published survey [To investigate the inherent variability and uncertainty of several of the parameters used in this study, we conduct a Monte Carlo analysis with assumed distributions for relevant parameters to determine the overall distribution of life cycle impacts, as shown in table In addition to the Base Case, we examine three scenarios relating to the e-scooter collection for charging and one additional scenario related to e-scooter lifetime.

Using the EPA Motor Vehicle Emission Simulator (MOVES) version 2014a, we determine a global warming (kg COGiven that shared dockless e-scooters are a recent phenomenon, comprehensive data do not yet exist for the distribution of lifetimes for these products under these usage conditions. To determine the distribution of the battery state of charge at pick-up, we collected end of day (8 pm–10 pm) data on 800 scooters through the Bird rider application. © 2005-2016 Alfresco Software Inc.

Additionally, cities could enact or enforce anti-vandalism policies to reduce e-scooter misuse or mistreatment which can result in short lifetimes (and thus high materials and manufacturing burdens per passenger-mile traveled).The scooter companies also can take meaningful action to reduce the life cycle burdens of their products.
