The U.S. Environment Protection Agency (EPA) has published documents to set Guidelines on Airport Emissions and Emission Reductions, which is encouraging airports to put efforts into reducing emissions from ground support equipment (GSE), such as lavatory service vehicles. Depending on their off-road utilization characteristics, lavatory service vehicles are subject to various emission regulations. Although most lavatory service vehicles are powered by gasoline or diesel, popularity of zero-emission GSE is expected to boost demand for electric lavatory service vehicles in the coming future. For example, over 22 airports in the U.S., including Seattle–Tacoma, Dallas-Fort Worth, and Philadelphia International Airport, are using over 230 electric vehicles. Increasing adoption of zero-emission GSE, including lavatory service vehicles, is expected to redefine growth prospects of the lavatory service vehicles market in the foreseeable future.
