Carbon footprint and automotive pollution are some important concerns in transportation field. Main objective of the present work is to propose, develop and implement the new complex method of computer aided measurement concerning carbon footprint in urban driving condition of a city car with instruments and equipment available at Technical University from Cluj-Napoca (TUCN). Specific objectives consist in experimental research of fuel consumption and economy coefficient, determination of pollutant emissions from the motor vehicle and pointing out the method’s fundamentals at TUCN. Applied research and testing results were gained, stored and fully analyzed with different interpretation tools. There were also highlighted the economy and carbon footprint trend lines in each particular context. Defining the set of expectations in fuel economy coefficient and carbon footprint is tight related to the consumption evaluation and research. Engine operating parameters and exhaust gases are not manifesting in isolation of the whole surrounding environment. The engine, the operating processes and the fuel efficiency should be studied in connection with the complex structure and multitude of influences which happens to be the entire motor vehicle moving on the city roads and impacting the surrounding ambient. The fuel efficiency and carbon footprint aspects have great influence on the vehicle’s use and its regime, but also they have a health and financial impact when it comes to mankind. Research perspectives are shown in order to ease up the further investigations of the outlined problems.
