Sažetak
Despite many efforts, total emissions from passenger cars have been increasing for the last few years. One reason for this is the rise in the number of passenger cars and their exploitation activities, but another one is the aging vehicle fleet, whose average age has risen since 2005. The 2008 global economic crisis affected new passenger car registrations, decreasing the number from nearly 90 000 that year to 45 000 in 2009. After Croatia became a member of the EU in 2013, the number of first registered second- hand passenger cars exceeded the number of newly registered passenger cars. Trends and changes in vehicle structure are unfavourable, the vehicle fleet is aging, and emissions generated by those vehicles are also increasing. More than 2 million vehicles were registered in Croatia in 2016, around 1.57 million of which were passenger cars. The average age of all registered vehicles in 2016 was 13.76 years. Passenger cars had a slightly lower average age of 12.76 years. Croatia, like all other EU member states, is obligated to collect, analyse and deliver emissions data (emissions inventory) to various institutions and bodies of the EU. Current emission estimations in Croatia were calculated using Tier 1 method which includes statistical fuel data for national road transport. Tier 1 is a simple method that uses basic data, so its usage is recommended only when no data other than fuel statistical data is available. If there is lack of data, EU member states ought to take measures in order to acquire more detailed data required for the application of improved methods. In order to estimate emissions more precisely, Tier 3 method is used which includes a variety of parameters like emission factors that take into account the average vehicle speed, and which divides emissions into hot and cold-start emissions. During this research, the vehicle fleet structure of Croatia was closely analysed and passenger car emissions were calculated for the period from 2007 to 2016 using COPERT 5, a Tier 3 capable program. Aside from data on air pollutants CO, NO_x, PM, NH_3, VOC and NMVOC the data shown includes greenhouse gas CO_2 as well as fuel consumption. Tracking the passenger car fleet and their exploitation activities for the mentioned period has shown a negative impact of the change of passenger car fleet has had on total emissions.
