Abstract

Ovaj rad analizira emisije ugljikovog dioksida (CO₂) kroz cijeli životni ciklus različitih vrsta vozila: električnih vozila, plug-in hibridnih vozila i vozila s motorima s unutarnjim izgaranjem. Korištenjem analize životnog ciklusa (LCA), procjenjuju se emisije tijekom faze proizvodnje, uporabe i reciklaže vozila. U analizu su uključeni pojedini koncepti uporabe u EU, SAD-u i Kini, za razdoblja od 5 i 10 godina te prosječnu godišnju vožnju od 20 000 kilometara.
Rezultati pokazuju da električna... More vozila imaju najniže emisije tijekom uporabe, posebno kada se električna energija dobiva iz obnovljivih izvora. Ipak, značajne emisije povezane su s proizvodnjom baterija i potrebnom reciklažom. Plug-in hibridna vozila pružaju ravnotežu između niskih emisija tijekom vožnje na električni pogon i mogućnosti korištenja fosilnih goriva. Vozila s motorima s unutarnjim izgaranjem imaju najveći izvor emisija zbog visokog udjela fosilnih goriva tijekom vožnje.
Rad naglašava potrebu za prelaskom na obnovljive izvore energije, poboljšanjem tehnologija baterija i razvojem održive prometne infrastrukture. U radu su iznesene preporuke za daljnja istraživanja koja bi mogla ubrzati smanjenje zagađivanja okoliša koji je uzrokovan prometom. Less

Abstract (english)

This paper analyzes carbon dioxide (CO₂) emissions throughout the entire lifecycle of various types of vehicles: electric vehicles, plug-in hybrid vehicles, and vehicles with internal combustion engines. By utilizing life cycle analysis (LCA), emissions are assessed during the production, usage, and recycling phases of the vehicles. The analysis incorporates usage patterns in the EU, the US, and China over periods of 5 and 10 years, with an average annual driving distance of 20 000... More kilometers.
The results show that electric vehicles have the lowest emissions during use, especially when electricity is sourced from renewable energy. However, significant emissions are associated with battery production and the necessary recycling process. Plug-in hybrid vehicles provide a balance between low emissions during electric driving and the flexibility to use fossil fuels. Vehicles with internal combustion engines have the highest emissions due to the significant reliance on fossil fuels during operation.
The paper emphasizes the need to transition to renewable energy sources, improve battery technologies, and develop sustainable transportation infrastructure. It also offers recommendations for further research that could accelerate the reduction of environmental pollution caused by transportation. Less
