This study examines the average age of light vehicles and the ownership cost of old used cars in New Zealand, finding that the PCO for a used EV is the lowest. Additionally, it highlights the potential of electric vehicles in reducing greenhouse gas emissions.
In New Zealand, the average age of a light vehicle in 2018 was 14.09 years. Despite having an old light vehicle fleet, no study has been conducted so far to calculate the per-kilometre cost of ownership (PCO) for old used cars. Therefore, this study attempts to identify the PCO of a new and a used light duty EV and light duty petrol-powered car over a 12-year period. The emissions reduction potential of EVs is also investigated. Findings are that the PCO for a used EV is the lowest (25.5 NZ cents) followed by the PCO for a used petrol-powered car (31.5 NZ cents). Most importantly, replacing a light petrol-powered ICEV by a light EV can reduce GHG emissions at the user level by 90% if New Zealand could maintain its low emission grid electricity. The findings have policy implications for countries that are considering rapid emissions reduction through EVs.
