Abstract The paper presents a comparative analysis of fire trucks with different types of power units, diesel, hybrid and fully electric. The study included general-purpose models: ATs 5.0-40 (MAZ-5309 chassis), Rosenbauer RT/RTX, Pierce Volterra, E-ONE Vector and Emergency One EV0, all of them are classified according to STB 11.13.04-2009 as heavy fire tankers with a gross vehicle weight of more than 14 t. All models have comparable weight in the range of 18–24 t, which ensures the validity of the comparison. In addition, a specialized airport fire truck Ziegler Z6 HYBRIDdrive was analyzed, which also belongs to the heavy class, but has a significantly higher mass (40 t) and is designed for use in specific conditions. The methodology was based on the calculation of energy consumption and CO2 emissions using typical operational modes: annual mileage, pump operation time and idle time, with reference fuel and electricity consumption rates. It was found that hybrid fire trucks reduce operating costs by up to 50 % and CO2 emissions by up to 70 % compared to diesel analogues, while fully electric models achieve over 98 % reduction of emissions. The scientific novelty lies in the application of a comprehensive methodology for assessing fire trucks with different types of power units adapted to the conditions of the Republic of Belarus, taking into account its low-carbon electricity profile. The practical significance is determined by the fact that hybrid fire trucks can serve as an optimal transitional stage of fleet modernization, combining ecological efficiency with operational reliability.
