Electric scooters (e-scooters) are one of the newest forms of shared micromobility in which private companies provide users with access to an e-scooter for a period time for nominal fee. These e-scooters typically can travel about 15-20 miles per hour with a range of about 20-30 miles on one charge. Because of their higher speed and greater range e-scooter may better substitute for vehicle travel than other micromobility modes like bike sharing systems.
To help assess the potential of shared e-scooters to decrease automobile usage and reduce greenhouse gas emissions, researchers at Université libre de Bruxelles (Free University of Brussels) in Brussels, Belgium conducted a lifecycle analysis of e-scooter systems. In this lifecycle analysis researchers took apart an e-scooter and estimated the greenhouse emissions from the manufacturing, charging, and disposal of these e-scooters. Researchers then conducted an online survey from June to August 2019 in the Brussels metropolitan area and asked respondents about their e-scooter usage patterns, including mode substitution habits. Finally, the research team combine the lifecycle analysis data with the survey data to build a model of the potential environmental affects of e-scooters considering different mode substitution patterns.
