The impact large vehicle fleets have on the environment is, as a rule, higher than the impact of private motor vehicles due to large annual mileage. A single management center for such fleets can provide more reliable information on the operating conditions of vehicles, and replacement of diesel engines with gas ones in vehicle fleets of large cities will improve the environmental conditions of urbanized areas. The article analyzes potential consumers of compressed-gas trucks in cities. The migration of vehicles of utility companies to natural gas will reduce the volume of harmful emissions to the atmosphere and the noise level at garbage pickup in the morning. Studies on the safety of compressed natural gas (CNG) vehicles have confirmed its high level. Nevertheless, reliability matters remain relevant. The suggested method for prediction of possible failures and service planning, as well as prediction of operating conditions will take into account the prospects of enlargement of gas-engine vehicle fleets and the ways to reduce the environmental load
